Colombia – Thoracic Surgery

ALAT : The Grand Trifecta

Talking about the roles of traditional VATS, single port surgery and robots in modern thoracic surgery.

The Ethicon (Johnson & Johnson) sponsored session was by far, the best of the conference – and an excellent overview of modern technologies in thoracic surgery.

Dr. Diego Gonzalez Rivas

“Is uni-port surgery feasible for advanced cancers?” Short answer: Yes.

The first speaker, was Dr. Diego Gonzalez Rivas of Coruna, Spain. He is a world-renown thoracic surgeon and innovator of uni-port thoracoscopic surgery. He discussed the evolution of single port surgery as well as the most recent developments with this technique, including more advanced and technically challenging cases such as chest wall resections (2013), sleeve resections/ reconstructions (2013), pulmonary artery reconstructions (2013) and surgery on non-intubated, awake patients (2014).

Experience and Management of bleeding

The biggest challenges to surgeons learning this technique is management of bleeding. But as he explained in previous lectures, this can be overcome with a direct approach. (these lectures and YouTube videos, Dr. Gonzalez explains the best ways to manage intra-operative bleeding.) In the vast majority of cases – this did not require deviation or conversion from the uni-port technique.)

As surgeons gain proficiency with this technique which mirrors open surgery, the only contra-indications for surgical resection of cancerous tissue (by single port) are tumors of great size, and surgeon discomfort with the technique.

Dr. Mario Ghefter

My favorite lecture of the series was given by Dr. Mario Ghefter of Sao Paolo, Brazil. While his lecture was ostensibly about video-assisted thoracoscopy (VATS), it was more of a retrospective vision and discussion of the modern history of thoracic surgery as seen through the eyes of a 22 year veteran surgeon.

He talked about the beginnings of VATS surgery and the contributions from such legends as Cefolio and D’Amico, including the 2005 paper – and modern-day thoracic bible, “Troubleshooting video-assisted thoracoscopic lobectomy (Demmy, James, Swanson, McKenna and D’Amico).

Dr. Ghefter also talked about how improved imaging and diagnostic procedures such as PET-CT and EBUS have been able to provide additional diagnostic information pre-operatively that helps surgeons to plan their procedures and treatment strategies more effectively.

As a counterpoint to both Dr. Gonzalez and Dr. Buitrago, Dr. Ghefter acquitted himself admirably. He reminded audience members that even the newer technologies have some drawbacks – both as procedures and for the surgeons themselves.

He also successfully argued (in my opinion) that while the popularity of procedures such as multiple port VATS and even open thoracotomies have dropped drastically as thoracic surgeons embrace newer technologies, there will always be a place and time for these more traditional procedures.

Dr. Mario Ghefter is the Director of Thoracic Surgery at Hospital do Servidor Público Estadual – Sāo Paulo and on staff at the Hospital Alemão Oswaldo Cruz.

Dr. Ricardo Buitrago

Native Colombian (and my former professor), Dr. Ricardo Buitrago is acknowledged as one of the foremost experts in robotic thoracic surgery in Latin America.

During his presentation, he discussed the principles and basics of use of robotic techniques in thoracic surgery. He reviewed the existing literature surrounding the use of robotic surgery, and comparisons of outcomes between thoracic surgery and traditional lobectomy.

He reviewed several recent robotic surgery cases and the use of robotics as a training tool for residents and fellows.

While he mentioned some of previously discussed limitations of robotic surgery (namely cost of equipment) he cited recent studies demonstrating significant cost savings due to decreased length of stay and a reduced incidence of surgical complications.

He also discussed recent studies (by pioneering surgeons such as Dr. Dylewski) demonstrated short operating times of around 90 minutes.

Awake Epidural Anesthesia for thoracoscopic pleurodesis

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.

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.

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.

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.

In the operating room with Dr. Mauricio Velaquez: Single port thoracoscopy

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. 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).

Cases proceeded rapidly; with no complications.

Robotic surgery with Dr. Ricardo Buitrago, thoracic surgeon

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.

buitrago 009 — 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.

Hope you enjoy.

Conference coverage: Bolivian Society of Cardiac, Thoracic and Vascular Surgery

Notes from the day’s lectures at the XVI Congreso Boliviana de Cirugia Cardiaca, Toracica u Vascular in Santa Cruz de la Sierra, Bolivia

This afternoon’s thoracic surgery offerings were provided in a more relaxed, round-table style discussion.

Dr. Edwin Crespo Mendoza, thoracic surgeon, of Santa Cruz, Bolivia led the discussion on diaphragmatic hernia repair and reminded the audience that over 50% of traumatic diaphragmatic hernias go undiagnosed at the time of initial presentation after trauma. To illustrate this, Dr. Crespo presented several cases including a case of post-traumatic hernia diagnosed 13 years after initial auto accident.

Dr. Fernando E. Jemio Ojara, MD (cardiothoracic surgeon) here in Santa Cruz at the Clinica Folanini presented a fascinating case of bilateral lung injury after blunt trauma. In this case, the patient was preparing to undergo urgent repair of a right-sided bronchial tear but during attempted intubation saturations dropped dramatically to 60%. At that time, the patient was placed on ECMO by venous cannulation to maintain oxygenation during the case. The surgeons proceeded with a right posteriolateral thoracotomy. Patient had a short successful ECMO run of 85 minutes, with extubated within 36 hours of surgery, and had no further problems post-operatively,

Dr. Ojara also discussed the mechanism of these type of acceleration – deceleration injuries that most commonly affect the right middle lobe, and how stabilization with ECMO is an effective strategy to repair what is essentially a functional pneumonectomy (in this particularly patient).

Dr. Fidel Silva Julio, Thoracic Surgeon also talked on a similar theme in his overview of closed chest trauma. He reminded the audience that 75-85% of all closed chest trauma patients need some sort of surgical management from chest tube placement to urgent surgery. He reviewed the classic presentations and radiographic findings in some of the most common conditions after chest trauma such as tension pnuemothorax/ sucking chest wounds, flail chest, pneumomediastinum, cardiac tamponade and pulmonary contusions. There were several medical students in the audience, taking notes – so I have included links to the radiology signs mentioned in his lecture, as well as a basic radiology primer.

He also highlighted the need to prevent the typical trauma pitfall of massive volume resuscitation which can prove extremely detrimental in these patients.

Simposia Internacional: Advances en Cancer Pulmonar y Mesotelioma

Highlights from the recent conference on Advances in Lung Cancer and Mesothelioma

Instituto Nacional de Cancero
Bogota, Colombia

Dr. Ricardo Buitrago and Dr. Juan Carlos Garzon, Thoracic Surgeons

This one day conference put on by the National Cancer Institute in Bogotá, Colombia highlighted the latest research and techniques of treating lung cancer and mesothelioma.

It was headlined by a trio of invited lecturers, Dr. Carlos Jimenez, MD, Pulmonologist (MD Anderson, Houston, TX), Dr. Garrett Walsh, MD, Thoracic surgeon (MD Anderson, Houston, TX) and Dr. Mark Dylewski, MD, Thoracic surgeon (Baptist Health/ South Miami Hospital – Center for Robotic Surgery).

Dr. Ricardo Buitrago (who readers will be hearing more about in the coming months) and Dr. Rafael Beltran were the moderators for the conference.

Dr. Jimenez spoke on the topics of endobranchial ultrasound and fine needle (Wang) aspiration for lymph node biopsy as an adjuvant of mediastinoscopy for cancer staging, as well as ‘medical thoracoscopy’ or pleuroscopy. (While I will never share his views of pleuroscopy being part of the role/ scope of pulmonology – it was an interesting presentation.)

The presentations of Dr. Walsh and Dr. Dylewski served as beautiful counter-balance to each other and demonstrated the spectrum and breadth of thoracic surgery in the treatment of thoracic diseases.

While Dr. Dylewski presented the latest data from his experiences performing over 355 cases by robotic approach, Dr. Walsh spoke about performing large open cases with an interdisciplinary team to treat later stage cancers (T3, T4 respectively) and the ability to resect cases that are often referred for medical treatment due to local metastasis to adjacent organs.

Other notable speakers included Dr. Stella Martinez who debated the advisability of surgical treatment of Malignant Pleural Mesothelioma (MPM) in response to another presentation by Dr. Walsh, as well as a discussion by Dr. Humberto Varela of the utility of specific diagnostic modalities for the detection and staging of malignant pleural mesothelioma.

Surgery at altitude, part I

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.

You can also contact me, K. Eckland, directly at : k.eckland@gmail.com. Please place ‘cirugia de torax’ or ‘altitude project’ in the sibject line.

Talking with Dr. Juan Carlos Garzon

Interview with Dr. Juan Carlos Garzon Ramirez in Bogota, Colombia

During a recent trip to Colombia, I stopped in to re-visit* renown Bogotá thoracic surgeon, Dr. Juan Carlos Garzon Ramirez. He’s tired from a long night with three back to back urgent cases – ending at 3 am but as always, he is charming, well-spoken and engaged in our discussions on thoracic surgery, and Bogotá, his home.

garzon 002 — Dr. Juan Carlos Garzon during a VATS procedure

Dr. Juan Carlos Garzon is a dynamic, innovative young surgeon and was recently named one of Bogotá’s Hottest Young Surgeons by Adriaan Alsema of Colombia Reports for his efforts (April 2011**). (This article highlights several young surgeons contributing to the advancement of the Colombian medical community.) He currently works at several facilities including Fundacion Cardioinfantil, Clinica del Country, Clinica Colombia (and other Colsanitas facilities).

After completing his thoracic surgery training at the El Bosque in Bogotá, he went to Hong Kong for additional thoracoscopy training. He now trains other surgeons in these surgical techniques

During my visit, we talked about what he sees as the future of thoracic surgery (more minimally invasive surgery) the role of thoracic surgery in the medical tourism phenomenon and the potential role of Bogotá surgeons in this growing trend.

We also discussed his reaction to The Bogotá Surgeons which examines the interplay and dynamics among the twenty practicing thoracic surgeons in Bogotá, as well as the upcoming Thoracic Surgery conference this October (which Dr. Garzon chairs.) This year’s featured speaker, is Dr. Shu S. Lin, noted lung transplant surgeon (previously interviewed here.)

The Thoracic Surgeons of Bogota

After living and working in Bogota, Colombia for the last five months as part of a separate project, I have decided that the story of the thoracic surgeons of Bogota needs to be told. I have been interviewing surgeons from multiple specialities day in and day out for months, but it the personal stories and the practice patterns of these thoracic surgeons that have emerged, which speak to me as a writer. It seems only natural after spending so much time with these fine surgeons to want to write a separate book, dedicated to these surgeons.

However, this book is not a fawning promotion brochure but a detailed glimpse into the behaviors, practices and history of thoracic surgery in Bogota.
Unlike my previous books, this is not a book about surgical tourism, though it would be incomplete without that information. Rather it is a brief narrative of the story of their daily lives, professional and personal and my perspectives as a stranger in the midst of these men and women.
I hope to complete The Thoracic Surgeons of Bogota by August, but I will keep you informed on my progress.
