a new film showing the life-changing efforts of one thoracic surgeon.. It’s about time!
Dr. Diego Gonzalez Rivas
I am excited beyond words to hear that my long-time hero and champion of modern-day thoracic surgery, Dr. Diego Gonzalez Rivas, is featured in a new documentary film, “This is Life”. The film follows the life of a patient undergoing a single incision thoracoscopic lobectomy. The film is being released this December.
I eagerly await the film – and am happy to see thoracic surgery (and Dr. Diego Gonzalez Rivas) get their due. For too long, our humble specialty has been overlooked for the more ‘glamorous’ cardiac surgery. This oversight has led to a dire shortage of thoracic surgeons in many parts of the world.
Hopefully, this is only part of an ongoing effort to have thoracic surgery recognized as an independent and complex surgical specialty requiring extensive knowledge, advanced skills and training. It is not an ‘add-on’ for cardiac surgeons with insufficient cardiac consultations.
Dr. Gonzalez Rivas and single-port surgery in Shanghai, China
For those of you hoping to see – and learn from the best, Dr. Gonzalez Rivas will be spending much of the month of October in Shanghai, China at the “National Uniportal VATS Training Course & Continuing Medical Education Forum on General Thoracic Surgery” which runs from October 8th to November 8th, 2014 at Tongi University.
Alas! To my eternal regret, Cirugia de Torax will not be in attendance. However, I will have sources on the ground – and hope to post more information during the conference,
in the operating room with Dr. Diego Gonzalez Rivas for single port thoracoscopic (uniportal) surgery.
Hilar mass resection using single port thoracoscopy with Dr. Diego Gonzalez – Rivas

Instituto Nacional de Cancerlogia
Bogota, Colombia
Surgeon(s): Dr. Diego Gonzalez Rivas and Dr. Ricardo Buitrago
Dr. Diego Gonzalez Rivas demonstrates single port thoracoscopy
Case History:
59-year-old female with past medical history significant for recurrent mediastinal mass previously resectioned via right VATS. Additional past medical history included prior right-sided nephrectomy.
Pre-operative labs:
CBC: WBC 7230 Neu 73% Hgb:14.1 Hct 37 platelets 365000
Pt 12.1 / INR1.1 PTT: 28.3
Diagnostics:
Pre-operative CT scan: chest
edited to preserve patient privacy
Procedure: Single port thoracoscopy with resection of mediastinal mass and lymph node sampling
After review of relevant patient history including radiographs, patient was positioned for a right-sided procedure. After being prepped, and draped, surgery procedure in sterile fashion. A linear incision was made in the anterior chest – mid clavicular line at approximately the fifth intercostal space. A 10mm port was briefly inserted and the chest cavity inspected. The port was then removed, and the incision was expanded by an additional centimeter to allow for the passage of multiple instruments; including camera, grasper and suction catheter.
Dr. Gonzalez Rivas and Dr. Ricardo Buitrago at National Cancer Institute
The chest cavity, pleura and lung were inspected. The medial mediastinal mass was then identified.
As previously indicated on pre-operative CT scan, the mass was located adjacent and adherent to the vessels of the hilum. This area was carefully dissected free, in a painstaking fashion. After freeing the mediastinal mass from the hilum, the remaining surfaces of the mass were resected. The mass was fixed to the artery pulmonary and infiltrating it) . The mass was removed en-bloc. Care was then taken to identify, and sample the adjacent lymph nodes which were located at stations (4, 7 and 10).
Following removal of the tumor and lymph nodes, the area was re-inspected, and the lung was re-inflated. A 28 french chest tube was inserted in the original incision, with suturing of the fascia, subcutaneous and skin layers.
closing the single port incision
Hemostasis was maintained during the procedure with minimal blood loss.
Patient was hemodynamically stable throughout the case, and maintained appropriate oxygen saturations. Following surgery, the patient was awakened, extubated and transferred to the surgical intensive care unit.
Post-operative: Post-operative chest x-ray confirmed appropriate chest tube placement and no significant bleeding or pneumothorax.

Discussion: Since the initial published reports of single-port thoracoscopy, this procedure has been applied to an increasing range of cases. Dr. Gonzalez and his team have published reports demonstrating the safety and utility of the single-port technique for multiple procedures including lobectomies, sleeve resections, segmentectomies, pneumonectomies and mediastinal mass resections. Dr. Hanao Chen (Taiwan) has reported several successful esophagectomies using this technical, as well as bilateral pleural drainage using a unilateral single-port approach.
Contrary to popular perception, the use of a single-port versus traditional VATS procedures (three or more) is actually associated with better visibility and accessibility for surgeons. Surgeons using this technical have also reported better ergonomics with less operating fatigue related to awkward body positioning while operating.
The learn curve for this surgical approach is less than anticipated due to the reasons cited above, and has been cited at 5 to 20 cases by Dr. Gonzalez, the creator of this approach.
The main limitations for surgeons using this technique is often related to anticipated (but potentially unrealized) fears regarding the need for urgent conversion to open thoracotomy. In reality, many of the complications that may lead to urgent conversion, such as major bleeding, are manageable thoracoscopically once surgeons are experienced and comfortable with this approach.
Dr. Gonzalez and his colleagues have reported a conversion rate of less than 1% in their practice. Subsequent reports by Dr. Gonzalez and his colleagues have documented these findings.
Other barriers to adoption of this technique are surgeon-based, and may be related to the individual surgeon’s willingness or reluctance to adopt new techniques and technology. Many of these surgeons would be surprised by how this technique mimics open surgery.
The successful adoption of this technique by numerous thoracic surgery fellows shows the feasibility and ease of learning single-port thoracoscopy by surgeons interested in adopting and advancing their surgical proficiency in minimally invasive surgery.
The benefits for utilizing this technique include decreased length of stay, decreased patient discomfort and greater patient satisfaction.

the 2013 S.W.A.T conference, presented by Johnson & Johnson. Featured presenters Dr. Diego Gonzalez Rivas and Dr. Paula Ugalde discuss single port thoracoscopy and topics in minimally invasive surgery
Very pleased that despite the initial difficulties, we are able to provide information regarding the recent conference.
Talking about Single-port surgery in Bogotá, Colombia – 2013 S.W.A.T. Summit
Dr. Diego Gonzalez Rivas and Dr. Paula Ugalde were the headliners at the recent Johnson and Johnson thoracic surgery summit on minimally invasive surgery. Both surgeons gave multiple presentations on several topics. They were joined at the lectern by several local Colombian surgeons including Dr. Stella Martinez Jaramillo (Bogotá), Dr. Luis Fernando Rueda (Barranquilla), Dr. Jose Maineri (Venezuela) Dr. Mario Lopez (Bogotá) and Dr. Pardo (Cartagena).

Target audience missing from conference
The audience was made up of thirty Latin American surgeons from Colombia, Costa Rica and Venezuela. This surgeons were hand-picked for this invitation-only event. Unfortunately, while Johnson and Johnson organized and presented a lovely event; their apparent lack of knowledge about the local (Colombian) thoracic surgery community resulted in the exclusion of several key surgeons including Dr. Mauricio Velasquez, one of Colombia’s earliest adopters of single-port thoracoscopy. Also excluded were the junior members of the community, including Dr. Castano, Dr. Carlos Carvajal, and current thoracic surgery fellows. It was an otherwise outstandingand informative event.

As discussed in multiple publications, previous posts as well as during the conference itself, it is these younger members who are more likely to adopt newer surgical techniques versus older, more experienced surgeons. More seasoned surgeons may be hesitant to change their practices since they are more comfortable and accustomed to open surgical procedures.
Despite their absence, it was an engaging and interesting conference which engendered lively discussion among the surgeons present.
Of course, the highlight of the conference actually occurred the day before, when Dr. Gonzalez- Rivas demonstrated his technique during two separate cases at the National Cancer Institute in Bogotá, Colombia. (Case report).

Featured presenters:
Dr. Diego Gonzalez – Rivas is a world-renown thoracic surgeon jointly credited (along with Dr. Gaetano Rocco) with the development of single-port thoracoscopic (uni-port) surgery. He and his colleagues at the Minimally Invasive Surgery Unit in La Coruna, Spain give classes and lectures on this technique internationally. Recent publications include three papers in July alone detailing the application of this surgical approach, as well as several YouTube videos demonstrating use of this technique for a wide variety of cases.

Refuting the folklore
Part of the conference focused on refuting the ‘folklore’ of minimally-invasive procedures. Some of these falsehoods have plagued minimally-invasive surgery since the beginning of VATS (in 1991), such as the belief that VATS should not be applied in oncology cases. The presenters also discussed how uniportal VATS actually provides improved visibility and spatial perception over traditional VATS (Bertolaccini et al. 2013).
However, Gonzalez-Rivas, Ugalde and the other surgeons in attendance presented a wealth of data, and publications to demonstrate:
– VATS is safe and feasible for surgical resection in patients with cancer. (Like all surgeries, oncological principles like obtaining clear margins, and performing a thorough lymph node dissection need to be maintained).
– Thorough and complete lymph node dissection is possible using minimally invasive techniques like single-port surgery. Multiple studies have demonstrated that on average, surgeons using this technique obtain more nodes than surgeons using more traditional methods.
– Large surgeries like pneumonectomies and sleeve resections are reasonable and feasible to perform with single-port thoracoscopy. Using these techniques may reduce morbidity, pain and length of stay in these patients.
– Rates of conversion to open surgery are very low (rare occurrence). In single-port surgery, “conversion” usually means adding another port – not making a larger incision.
– Learning curve fallacies: the learning curve varies with each individual surgeon – but in general, surgeons proficient in traditional VATS and younger surgeons (the “X box generation”) will readily adapt to single-port surgery.
– Bleeding, even significant bleeding can be managed using single-port thoracoscopy. Dr. Gonzalez Rivas gave a separate presentation using several operative videos to demonstrate methods of controlling bleeding during single-port surgery – since this is a common concern among surgeons hesitant to apply these advanced surgical techniques.

While I advance criticism of this event – it was a fantastic conference. My only reservations were to the exclusivity of the event. While this was certainly related to the costs of providing facilities and services for this event – hopefully, the next J & J thoracic event will be open to more interested individuals including young surgeons and nurses.
writing about Dr. Diego Gonzalez Rivas and the other living legends in thoracic surgery and connecting people to the world of thoracic surgery
Readers at Cirugia de Torax have certainly noticed that there are numerous articles regarding the work of Dr. Diego Gonzalez Rivas. This week in particular, after a recent thoracic surgery conference and an afternoon in the operating room – there is a lot to say about the Spanish surgeon.
It’s also hard to escape that fact that I regard him in considerable awe and esteem for his numerous contributions to thoracic surgery and prolific publications. I imagine that this is similar to how many people felt about Drs. Cooley, Pearson or Debakey during their prime.
Making thoracic surgery accessible
But the difference is Dr. Diego Gonzalez Rivas himself. Despite the international fame and critical surgical acclaim, he remains friendly and approachable. He has also been extremely supportive of my work, at a time when not many people in thoracic surgery see the necessity or utility of a nurse-run website.
After all, the internet is filled with other options for readers; CTSnet.org, multiple societies like the Society of Thoracic Surgeons (STS), and massive compilations like journal-based sites (Annals of Thoracic Surgery, Journal of Thoracic Disease, Interactive Journal of Cardiothoracic Surgery).
But the difference between Cirugia de Torax and those sites is like the difference between Dr. Gonzalez Rivas and many of the original masters of surgery: Approach-ability and accessibility.
This site is specifically designed for a wider range of appeal, for both professionals in thoracic surgery, and for our consumers – the patients and their families. Research, innovation, news and development matters to all of us, not just the professionals in the hallowed halls of academia. But sometimes it doesn’t feel that way.
Serving practicing surgeons
For practice-based clinicians, and international surgeons publication in an academia-based journal requires a significant effort. These surgeons usually don’t have research assistants, residents and government grants to support their efforts, collect their data and clean up their grammar. Often English is a second or third language. But that doesn’t mean that they don’t make valuable contributions to their patients and the practice of thoracic surgery. This is their platform, to bring their efforts to their peers and the world.
Heady aspirations
That may sound like a lofty goal, but we have readers from over a 110 countries, with hundreds of subscribers along with over 6,000 people with Cirugia de Torax directly on their smart phone. Each month, we attract more hits and more readers.
Every day, at least 200 people read “Blebs, Bullae and Spontanous Pneumothorax”. Why? Because it’s a concise article that explains what blebs are, how a pneumothorax occurs and how it’s treated. Another hundred people usually go on to read the accompanying case report about blebectomy, for similar reasons. There are links for more information, CT scans and intra-operative photos included, so that people can find exactly what they need with a minimum of effort.
Avoiding ‘Google overload’
With the massive volume of information available on the internet, high-quality, easily understood, applicable information has actually become even more difficult for patients to find than ever before. Patients spend hours upon hours browsing through academic jargon, commercial websites and biased materials while attempting to sift through the reams of information for pertinent and easily understandable information. There is also a lot of great material out there – so we provide links to reputable sites, recommend well-written articles and discuss related research.
Connecting patients to surgeons
We also provide patients with more information about the people they are entrusting their bodies, their hopes and their lives to. It’s important that they know about the Dr. Benny Wekslers, the Dr. Hanao Chens, and the Dr. Diego Gonzalez Rivas out there.
Update: June 2019
After multiple reader requests from this site, we have launched a service to assist readers in pursuiting minimally invasive thoracic surgery, uniportal surgery, HITHOC and other state-of-the-art thoracic surgery procedures with the modern masters of thoracic surgery. We won’t talk a lot about this on the site, but we do want readers to know that we are here to help you. If you are wondering what surgery costs like with one of the world’s experts – it’s often surprisingly affordable.
If you are interested in knowing more, please head to our sister site, www.americanphysiciansnetwork.org or send an email to kristin@americanphysiciansnetwork.org.
Keeping it ‘real’
Looking over the shoulder of Dr. Gonzalez Rivas in the operating room
As much as I may admire the work and the accomplishments of Dr. Gonzalez-Rivas – it’s important not to place him on a pedestal. He and his colleagues are real, practicing surgeons who operating on regular people, not just heads of state and celebrities. So when we interview these surgeons and head to the OR, it’s time to forget about the accolades, the published papers and the fancy titles. It’s time to focus on the operations, the techniques, the patients and the outcomes because ‘master of thoracic surgery’ or rural surgeon – the operation and patient are all that really matters.
Reviewing “Ten years experience on 644 patients undergoing single-port (uniportal) video-assisted” by Gaetano Rocco et al. at the National Cancer Institute in Naples, Italy
In this month’s issue of the Annals of Thoracic Surgery, Dr. Gaetano Rocco and his colleagues at the National Cancer Institute, Pascale Foundation in Naples, Italy reported their findings on ten year’s worth of single-port surgery in their institution.
Who: 644 patients; (334 males, 310 females)
Indications:
Annals of thoracic surgery – Rocco et. al (2013)
What: Outcomes and experiences in single port thoracic surgery over a ten-year period. All procedures performed by a single surgeon at this institution, and single-port VATS accounted for 27.7% of all surgeries performed during this time period.
When: data collected on thoracic surgery patients from January 2000 – December 2010.
Technical Notes:
Pre-operative CT scan was used for incision placement planning. Incision was up to 2.5 cm (1 inch) in length depending on indications for surgery.
Conversion rate to 2 or 3 port VATS: 2.2% (14 patients)
Conversion to mini-thoracotomy: 1.5% (10 patients)
Patients underwent conversion due to incomplete lung collapse (22 patients) and bleeding (2 patients).
There were no re-operations or “take backs”. The four patients with malignant effusions who died within the 30 day post-op period were re-admitted to the ICU.
Post-operatively:
Otherwise, all patients were admitted to either the floor or the step-down unit following surgery.
Pain management: post-operative pain was managed with a non-narcotic regimen consisting of a 24 hour IV infusion pump of ketorolac (20mg) and tramadol (100mg*). After the first 24 hours, patients were managed with oral analgesics such as paracetamol (acetaminophen).
Limitations: in this study, uni-port VATS was not used for major resections, as seen in the work of Dr. Diego Gonzalez and others. This may be due to the fact that uni-port VATS was an emerging technique at the initiation of this study.
Strengths: This is one of the largest studies examining the use of single-port thoracic surgery – and showed low morbidity and mortality. (Arguably, the 30 day mortality in this study was related to the patients’ underlying cancers, rather than the surgical procedure itself.)

Discussing Dr. Joseph Coselli and ‘the cowboys of cardiac surgery’ along with some of our own heros of thoracic surgery here at Cirugia de Torax.
There’s a great article in this month’s Annals of Thoracic Surgery, by Dr. Joseph Coselli, from Texas Heart Institute and the Michael DeBakey Department of Surgery at Baylor. His article, entitled,” My heros have always been cowboys” is more than just a title torn from the song sheets of Willie Nelson. It’s a look back at both the pioneers of cardiac surgery and his own experiences as a cardiac surgeon. He also discusses the role of surgeons, and medical practitioners in American society in general and the promises we make to both society at large and our patients.
Here at Cirugia de Torax, I’d like to take a moment to look back at the surgeons that inspired and encouraged me in this and all of my endeavors. Some of these surgeons knew me, and some of them didn’t – but their encouragement and kindnesses have spurred a career and life that have brought immense personal and professional satisfaction.
Like Dr. Coselli, I too, took inspiration from the likes of Dr. Denton Cooley. But our stories diverge greatly from there. I never met Dr. Cooley and I probably never will. But it was a related story, from my former boss (and cardiothoracic surgeon), Dr. Richard Embrey that led to an email to Dr. Cooley himself. My boss had too trained under Dr. Cooley, Dr. Debakey and the Texas Heart Institute, the citadel of American heart surgery. Then, somehow, along the way – Dr. Embrey stopped to work at our little rural Virginia hospital. We were the remnants of a larger Duke cardiothoracic program but we were a country hospital all the same.
While I learned the ins and outs of surgery from Dr. Embrey (and Dr. Geoffrey Graeber at West Virginia University) on a day-to-day basis, I was also weaned on the folklore of cardiothoracic surgery – stories of the giants of history, like the ones mentioned in Dr. Coselli’s article, as well as local Duke legends who occasionally roamed the halls of our tiny ICU and our two cardiothoracic OR suites; Dr. Duane Davis, Dr. Shu S. Lin and Dr. Peter Smith. While never working side-by-side, Dr. D’Amico’s name was almost as familiar as my own. As the sole nurse practitioner in this facility, without residents or fellows, there was no buffer, and little social divide in our daily practice. Certainly, this changed me – and my perceptions. I asked the ‘stupid’ questions but received intelligent and insightful answers. I asked even more questions, and learned even more..
These opportunities fed my mind, and nurtured my ambitions. Not to be a physician or a doctor, but to learn as much as possible about my specialty; to be the best nurse possible in my field. It also nurtured a desire to share these experiences, and this knowledge with my peers, my patients and everyone else who ever had an interest.
It was that tiny little email, a gracious three-line reply from Dr. Cooley himself that made me realize that I didn’t have to rely on folklore and second-hand stories to hear more. That’s critical; because as we’ve seen (here at Cirugia de Torax) there are a quite of few of “Masters of thoracic surgery” or perhaps future giants that haven’t had their stories told. Dr. Coselli and his fellow writers haven’t written about them yet.. So I will.
Sometimes I interview famous (or semi-famous) surgeons here, but other times, I interview lesser-known but equally talented/ innovative or promising surgeons. All of them share similar traits; dedication and love for the profession, immense surgical talent and proficiency and sincere belief in the future of technology of surgery.
So, let’s hope that it won’t take forty more years for these surgeons to be recognized for their contributions to thoracic surgery in the way that Cooley, DeBakey and Crawford are heralded in cardiac surgery.
Awake epidural anesthesia for thoracoscopic pleurodesis: A prospective cohort study. a new publication from Dr. Mauricio Velasquez and his surgical team reviewing results from their 36 month study
On the heels of a recent announcement on CTSnet.org soliciting surgeon input on their experiences with non-general anesthesia for thoracic surgery procedures, Cirugia de torax is revisiting one of the surgeons we interviewed last year, Dr. Mauricio Velasquez at Fundacion Valle de Lili in Cali, Colombia.
Dr. Velasquez in the operating room with Lina Caicedo Quintero (nurse) Valle de Lili, Cali, Colombia
The trip to Cali was primarily to discuss Dr. Velasquez’s Thoracic Surgery Registry, and to observe him performing several single port surgery cases. However, during the trip, Dr. Velasquez also spoke about several other aspects of his current practice including some of his recent cases, and the thoracic surgery program at Fundacion Valle de Lili.
Dr. Mauricio Velasquez after another successful case
We also talked with his wife, (and lead author), the talented Dra. Cujiño, an anesthesiologist who subspecializes in thoracic anesthesia. Together, they have successfully performed several thoracic cases using thoracic epidural anesthesia on awake patients.
By chance, they published articles in both Revista Colombianas de anesthesia and Neumologia y cirugía de torax in the last few weeks.
Revista Colombianas de anesthesia
Patients receiving epidural anesthesia received a small dose of midazolam prior to insertion of epidural needle at the T3 – T4 intervertebral space. During the case, patients received bolus administration via epidural of 0.5% bupivacaine on a prn basis.
Short surgeries, single port approach
All patients, regardless of anesthesia type underwent single port thoracoscopic surgery for the talc pleurodesis procedure. Surgery times were brief, averaging 30 to 35 minutes for all cases (range 25 – 45 minutes) with the epidural patient cases being slightly shorter.
Dr. Mauricio Velasquez performing single port thorascopic surgery
Dramatic reduction in length of stay
In their study, patients receiving awake anesthesia had an average length of stay of four days compared with ten days for the general anesthesia group.
Decreased incidence of post-operative complications
There was a marked reduction in the incidence of post-operative respiratory complications (19 in general anesthesia group) versus 3 patients in the awake anesthesia group. Post-operative mortality was also decreased (six in general anesthesia) versus two deaths in the awake anesthesia group. However, the mortality statistics may also be impacted by the overall poor prognosis and median survival time of patients presenting with malignant effusions.
Post-operative pain
Study patients also self-reported less post-operative pain in the awake anesthesia group – with only one patient reporting severe pain versus seven patients in the general anesthesia group.
Conclusions
Cujiño, Velasquez and their team found awake thoracic epidural anesthesia (ATEA) was a safe and effective method for intra-operative anesthesia and was associated with a decreased post-operative pain, decreased length of stay (LOS) and decreased incidence of post-operative complications.
Notes
This study was funded by the authors with no relevant disclosures or outside financial support.
the latest video from Dr. Diego Gonzalez Rivas demonstrating a sleeve lobectomy via single port surgery
On the heels of the recent conference in Hong Kong, one of our favorite surgeons (and presenter at the 1st Asian single port surgery conference), Dr. Diego Gonzalez Rivas has sent another link to one of his more recent cases – Single port lobectomy – Sleeve resection after chemotherapy.
the latest predictions on the impending shortage of surgeons in the United States
Unsurprisingly – rural area hospitals face additional challenges in attracting and retaining specialty surgeons in comparison to big cities/ metropolitan areas. However, as reported by Patrice Welding at Thoracic Surgery News in a report on the annual meeting of the Central Surgical Association, this may be viewed as a boon for the surgeons themselves as hospitals may devise new and enhanced incentives to attract surgeons to their facilities. The surgical specialties most likely to benefit from this strategy include (as previously reported), obstetrics and gynecology, orthopedic surgery, general surgery, otolaryngology, urology, neurosurgery, and thoracic surgery.
The article which quotes Dr. Thomas E. Williams, Jr. predicts that hospitals and institutions may break out into a ‘bidding war’ over surgeons.
While this is dire news for rural hospitals and the estimated 56 million patients served by these facilities, it comes as a relief for current thoracic surgery fellows and new thoracic surgeons who have faced an increasingly bleak economic landscape over the last few years.
Of course, more sanguine experts note that the impact of the impending shortage has been reported for several years – with little impact on the current job market for new graduates.
Dr. Thomas E. Williams Jr. is one of the main researchers on the impending shortage in the United States and published a book based on his findings in 2009, entitled, “The coming shortage of surgeons: why they are disappearing and what that means for our health“. (Praeger, ISBN #978-0313380709). His work has also be published in multiple journals, and presented in meetings and conferences across the country.
Interested in learning more about single port thoracoscopy, or talking to the inventors of this technique? This March – head to the 1st Asian single port surgery conference in Hong Kong.
It doesn’t look like Cirugia de Torax will be in attendance for this conference, but it’s another opportunity for practicing thoracic surgeons and thoracic surgery fellows to learn more about single port thoracoscopic surgery.
This March (7th – 8th), the Chinese University of Hong Kong, along with the Minimally Invasive Thoracic Surgery Unit (Coruna, Spain), and Duke University are presenting the 1st Asian Single Port Symposium and Live Surgery conference in Hong Kong.
This is your chance to meet the experts – and the inventors of this technique (such as Dr. Diego Gonzalez – Rivas, one of the new masters frequently featured here at Cirugia de Torax.)
a day in the operating room with one of Colombia’s New Masters of Thoracic Surgery
Cali, Colombia
Dr. Mauricio Velasquez is probably one of the most famous thoracic surgeons that you’ve never heard of. His thoracic surgery program at the internationally ranked Fundacion Valle del Lili in Cali, Colombia is one of just a handful of programs in the world to offer single port thoracic surgery. Dr. Velasquez has also single-handedly created a surgical registry for thoracic surgeons all over Colombia and recently gave a presentation on the registry at a national conference. This registry allows surgeons to track their surgical data and outcomes, in order to create specifically targeted programs for continued innovation and improvement in surgery (similar to the STS database for American surgeons).
Dr. Mauricio Velasquez after another successful case
Dr. Velasquez is also part of a team at Fundacion Valle del Lili which aims to add lung transplant to the repertoire of services available to the citizens of Cali and surrounding communities.
He is friendly, and enthusiastic about his work but humble and apparently unaware of his growing reputation as one of Colombia’s finest surgeons.
Education and training
After completing medical school at Universidad Pontificia Bolivariana in Medellin in 1997, he completed his general surgery residency at the Universidad del Valle in 2006, followed by his thoracic surgery fellowship at El Bosque in Bogotá.
The Colombia native has also trained with thoracic surgery greats such as Dr. Thomas D’Amico at Duke University in Durham, North Carolina, and single port surgery pioneer, Dr. Diego Gonzalez Rivas in Coruna, Spain. He is also planning to receive additional training in lung transplantation at the Cleveland Clinic, in Cleveland, Ohio this summer.
Single port surgery
Presently, Dr. Velasquez is just one of a very small handful of surgeons performing single port surgery. This surgery is an adaptation of a type of minimally invasive surgery called video-assisted thoracoscopy. This technique allows Dr. Velasquez to perform complex thoracic surgery techniques such as lobectomies and lung resections for lung cancer through a small 2 – 3 cm incision. Previously, surgeons performed these operations using either three small incisions or one large (10 to 20cm) incision called a thoracotomy.
By using a tiny single incision, much of the trauma, pain and lengthy hospitalization of a major lung surgery are avoided. Patients are able to recovery and return to their lives much sooner. The small incision size, and lack of rib spreading means less pain, less dependence on narcotics and a reduced incidence of post-operative pneumonia and other complications caused by prolonged immobilization and poor inspiratory effort.
However, this procedure is not just limited to the treatment of lung cancer, but can also be used to treat lung infections such as empyema, and large mediastinal masses or tumors like thymomas and thyroid cancers.

Team approach
Part of his success in due in no small part to Dr. Velasquez’s surgical skill, another important asset to his surgical practice is his wife, Dr. Indira Cujiño, an anesthesiologist specializing in thoracic anesthesia. She trained for an additional year in Spain, in order to be able to provide specialized anesthesia for her husband’s patients, including in special circumstances, conscious sedation. This allows her husband to operate on critically ill patients who cannot tolerate general anesthesia. While Dr. Cujiño does not perform anesthesia for all of Dr. Velasquez’s cases, she is always available for the more complex cases or more critically ill patients.
In the operating room with Dr. Velasquez
I spent the day in the operating room with Dr. Velasquez for several cases and was immediate struck by the ease and adeptness of the single port approach. (While I’ve written quite a bit about the literature and surgeons using this technique, prior to this, I’ve had only limited exposure to the technique intra-operatively.) Visibility and maneuverability of surgical instruments was vastly superior to multi-port approaches. The technique also had the advantage that it added no time, or complexity to the procedure (unlike robotic surgery).

Dr. Chen discusses single port thoracoscopy – and specimen size.
Single port thoracoscopy for wedge resection – does size matter? Dr. Chih-Hao Chen, Thoracic Surgeon, Mackay Memorial Hospital, Taiwan Correspondence: musclenet2003@yahoo.com.tw
Case presentation and discussion
A 77 y/o woman was found to have a neoplasm in RML during routine health exam. (Full case presentation here.)
The incision was 2.5 cm. The specimen was removed successfully; patient experienced no complications and was discharged from the hospital without incident. However, when discussing this case with surgeon colleagues a specific question arose.
preparing to remove the specimen through the port
Does size matter? How big is too big to remove through a port incision?
An important issue is the theoretically smallest (and effective) incision size. The issue is very challenging for most surgeons. In the past, other surgeons have questioned me :
“The specimen to be removed is more than 12-15 cm. How can you remove the specimen from a 3.5 cm incision?”
BUT, the fact is “the smallest size depends mostly on the solid part of the neoplasm “.
The lung is soft in nature. In my experience, a 3.5 cm port is usually enough for any lobe. The only problem is that if the solid part is huge, pull-out of the specimen may be difficult.
Therefore, the solid part size is probably the smallest incision size we have to make, usually in the last step when dissection completed , if needed.

Using endo-bags to avoid larger incisions
There is an exception. I have never do this but I think it may be possible. We usually avoid opening the tumor (or cutting tumor tissue into half ) within the pleural space in order to prevent metastasis from spillage of cancerous tissue.
What if we can protect the tumor from metastasis while we cut it into smaller pieces? For example, into much smaller portions that will easily pass through the small port incisions?
My idea is to use double-layer or even triple layers of endo-bag to contain the specimen. If it is huge, with perfect protection, we cut it into smaller parts within the bag. Then the huge specimen can be removed through a very tiny incision. This is possible.
We still have to avoid “fragmentations” since this might interfere or confuse the pathologist for accurate cancer staging. Therefore, in theory, we can cut it into smaller parts but not into fragments. However this idea is worthy of consideration, and I welcome debate from my fellow surgeons and medical colleagues.
Robotic (thoracic) surgery comes to Clinica de Marly in Bogota, Colombia
A year and a half ago, I interviewed and spent some time with Dr. Ricardo Buitrago at the National Cancer Institute, and Clinica de Marly while doing research for a book about thoracic surgeons. At that time, Dr. Buitrago stated he was interested in starting a robotic surgery program – and was planning to study robot-assisted thoracic surgery with Dr. Mark Dylewski.
Dr. Ricardo Buitrago in the operating room, April 2011
Fast forward 1 year – when I received a quick little email from Dr. Buitrago telling me about his first robotic surgery at the Clinica de Marly. At that point, I sent Dr. Buitrago an email asking if I could come to Colombia and see his robotic surgery program to learn more about it. We had several phone conversations about it and I also outlined a research proposal to gather data on thoracic surgery patients and outcomes at high altitude, to which he enthusiastically offered to assist with. Thus began my current endeavor, in Bogota, studying with Dr. Buitrago.
Now – after completing a proctoring period with Dr. Dylewski, Dr. Buitrago has more than a dozen independent robotic surgeries under his belt. He has successfully used the robot for lobectomies, mediastinal mass resections and several other surgeries.
As part of my studies with Dr. Buitrago – I’ve made a video for other people who may be interested in robotic surgery with the DaVinci robot and what it entails.
Developing electronic applications to ease the task of data collection for clinical research.
In clinical research; results are dependent on data. Data is only as good as the data collection tools used to gather it. Furthermore, the best and most accurate data comes from the surgeon or the surgical team themselves at the time of care (versus third-party lay person data collection via chart review). However, there are some limitations that are imposed when following these guidelines; such as the collection of 30-day follow-up information.
Data collection needs to be simple and relatively speedy. The ideal tools allow surgeons to collect the essential data at the time of discharge (when information is fresh), limit additional paper accumulation and are submitted at the time of completion. This necessitates the development of electronic applications.
At the time of this writing, I am currently working on the development of both smart phone and web-based applications for data collection for the altitude project. These electronic forms will allow data to be entered and submitted at the time of collection.
smart phones for data collection
A secondary application is being developed to address the patient re-admission or development of complications post-discharge in the first thirty days after discharge.
Downloadable pdfs and/or spreadsheets will also be available for surgeons who elect to use the ‘paper’ option.
Since the data has only limited patient identifiers, and all data is being submitted to a clinical investigator, (versus outside companies) patient privacy is protected.
When completed, further information will be posted here at Cirugia de Torax.
Calling all thoracic surgeons – particularly those in La Paz, Quito, Bogota and Mexico City.. We have an opportunity for collaborative research.
One of our newest endeavors is a research project on thoracic surgery at moderate altitude. We’ve completed our review of existing literature, and developed our patient parameters and data collection points.
The main base of our operations is Flagstaff, Arizona, which is located at 7000 ft. (2,000 meters) making it the highest altitude cardiothoracic program in the United States. The Flagstaff site has several strengths in that much of our patient population comes from the surrounding areas; which are located at both higher and lower elevations. However, one of the weaknesses in Flagstaff is our small patient population – as a single surgeon site devoted to both cardiac and thoracic surgery – our lung surgery volumes are fairly small.
Right now, I am doing some of the preliminary work with the hospital – meeting with staff to apply for IRB approval, and formalizing the data collection process. I am also interested in recruiting surgeons from other sites to participate in data collection. Dedicated thoracic surgeons with large thoracic surgery practices would be ideal – and all results will be published and presented by surgeon/ and site.
We are particularly interested in recruiting surgeons from the following areas:
1. La Paz, Bolivia
2. Quito, Ecuador
3. Bogotá, Colombia
4. Mexico City, DF – Mexico
These four cities combined house many millions of people living at moderate altitudes, and would help provide for a wider and more expansive collection of data on patients undergoing thoracic surgery. Demographic differences (such as pre-existing thoracic diseases, incidence of heavy cigarette smoking, etc.) of geographic locales will also allow for further points of comparison.
Please contact Cirugia de Torax if you are interested in participating. All participating surgeons and institutions will receive credit (in accordance to level of participation) in any and all subsequent professional and scientific publications.

The majority of general thoracic surgical operations in the United States are performed by surgeons not specializing in thoracic surgery. [despite the fact that] Both general thoracic surgeons and cardiac surgeons achieve better outcomes than general surgeons.” Schipper et. al (2009).
Research has shown that speciality specific training contributes greatly to surgical outcomes, yet large numbers of surgeons persist in operating outside their area of expertise.
In fact, in the United States, the majority of thoracic surgery procedures are not performed by board-certified thoracic surgeons. Unfortunately, the majority of patients are uninformed about the different training and subspecialties among surgeons, and it appears that general surgeons are not hastening to inform them. While most patients are sophisticated enough to realize and understand that a general surgeon is not the best candidate to remove a large brain tumor, this does not apply to a lung tumor.
Why does this happen? As Wood & Farjah (2009) explain: (italics are mine)
“Thoracic surgeons are well aware of the apparent moral hazard that occurs in a community when a patient is referred to the local general surgeon for lung cancer resection but to the general thoracic surgeon if the patient is higher risk, is a “VIP” (health professional or relative, community or business leader), or if the patient demands specialist care. If high-risk or “important” patients benefit from operations done by thoracic surgeons, it seems likely that other patients will as well. This tacit understanding of the benefits of specialty care is obvious and is supported by research from Schipper and others, yet appears to be undermined by local factors that have yet to be confronted by hospitals, payers, patient advocacy groups, or policy makers.
Physicians referring patients requiring thoracic operations may prefer to direct a patient to a nonspecialist due to local politics and economics, potentially benefiting directly or indirectly if the patient is cared for within the same hospital or same medical group. Although many hospital credentials committees require specialty board certification to provide specialty care, this is often overlooked because of local traditions, reluctance to restrict or offend current medical staff, and concern about potential financial implications if lack of hospital “specialists” results in redirection of certain patients to a competing hospital.”
“National specialty societies representing surgeons are generally silent on the issue in an effort to avoid disenfranchising one or more of their constituencies. These well-intended but incongruous local incentives could be overcome by policy decisions by health care systems, payers, agencies evaluating quality, and government policy makers.”
Does local politics, local traditions and financial incentives to the referring physician seem like a good reason to refer a patient to an unqualified surgeon – when conclusive, and comprehensive data shows otherwise?
