Talking with Dr. Diego Gonzalez Rivas about single port surgery

an Interview with Dr. Diego Gonzalez Rivas – and coverage of ‘Videotoracoscopia y cirugia robotica en torax: Avances y perspectivas’ in Santiago, Chile

Santiago, Chile

I was a little intimidated to actually interview Dr. Diego Gonzalez Rivas after reading his articles and pestering him with emails for the last few years.  But he was just as nice and patient with my questions as he’s always been.

Dr. Diego Gonzalez

Dr. Gonzalez is here in Santiago for the single port thoracic surgery / robotic surgery conference at Clinica Alemana, hosted by Dr. Raimundo Santolaya.

Dr. Santolaya, Dr. Sales dos Santos, Dr.Berrios and Dr. Diego Gonzalez Rivas

Since publishing the last few articles on his single port technique, Dr. Gonzalez has been in high demand from thoracic surgeons wanting to learn more, and to train in single port techniques.  In addition to traveling the world to teach – he continues to offer training at the Minimally Invasive Thoracic Surgery Unit at the Complexo Hospitalario Universitario de A Coruna, in Coruna, Spain.


Dr. Gonzalez reports that single port thoracoscopy doesn’t just provide patients with the least invasive surgery possible, but that single port thoracoscopy is superior to traditional VATS in the vast majority of cases.  Single port thoracoscopy is defined by the creation of one 2cm to 4cm incision – with no rib spreading and utilization of video-assisted thoracoscopy.

“Forward Motion”

He states that using a single port approach gives much better visibility than traditional VATS.  This visibility is equal to that of open surgery – versus the 3 or 4 port approach, which is constrained by the 30 degree movement / rotation of the thoracoscope.  This visibility concept; called ‘Forward Motion,’ along with the ease of using instrumentation through the same port makes single port surgery amendable to most thoracic surgery procedures.

Learning curve? What learning curve?

He reports that members of the “Playstation Generation” as he terms the newest young surgeons, adapt more readily to the use of both traditional and single port thoracoscopy.  In fact,  he reports that the residents (in his program) are able to learn and use this approach with minimal assistance.

With the exception of lung transplantation (requiring the traditional clamshell incision), Dr. Gonzalez reports that he is able to successfully perform a wide range of surgeries from wedge resections and lobectomies to more complicated procedures such as pneumonectomies and sleeve resections.

In today’s lecture he debunks some of the myths regarding the ‘classic contraindications’ to video-assisted thoracoscopy (VATS) such as broncheoplasty, the presence of dense adhesions or the need for complete lymph node dissection.  While he reports that dense adhesions may make the procedure more painstaking and difficult – it is still possible.

Lymph Node Dissection

In cases of lymph node dissection – he reports that lymphadenectomy is actually superior by single port and other VATS methods, with the average surgeon actually harvesting more nodes, more easily.

While he initially believed that right upper lobe resections would be impossible with this method – his recent experiences (included in an upcoming paper on 102 cases) show that any anatomic complexities are readily overcome by an experienced VATS surgeon.  Not only that, but he has been able to successfully remove very large (8cm or greater) lung tumors using this method – by slightly enlarging the port at the time of specimen removal.  He has also successfully removed Pancoast tumors and performed chest wall resections with this procedure, as well as single port thoracoscopy after previous VATS or previous thoracotomy including completion pnuemonectomies and completion sleeve lobectomies.

One of the biggest obstacles for surgeons implementing the single port method is the dreaded complication of catastrophic bleeding.  This often causes inexperienced single port surgeons to hasten to convert to open surgery without attempting to control the bleeding.  Dr. Gonzalez presented several cases today to demonstrate the difference between controlled bleeding that can be managed with the speedy application of surgical staples, clips or sutures versus heavy uncontrolled bleeding, which requires quick recognition and prompt conversion to open thoracotomy.

He reports that in the over 500 cases he has performed by VATS (3 port, dual port and single port), conversion to open thoracotomy remains a very rare occurence.  (He presented data on his outcomes today.)

In his own practice, he reports that prior to 2007 the majority of cases were by traditional thoracotomy.  He began using 3 port VATS more heavily in 2007 – 2009.  After training with Dr. D’Amico at Duke  University in Durham, NC – he moved to dual port thoracoscopy in 2009.  Since 2010, his practice is almost exclusively single port thoracoscopy.

The future of single port thoracoscopy

Dr. Gonzalez believes the future of single port thoracoscopy will be a hybridization of current robotic thoracic surgery (which now uses three and four port techniques) to using less invasive, smaller robotic arms that will allow surgeons to enjoy the micro-precision of robotic technology through a single port.

Not just a ‘single port surgeon’

While he is famous internationally for his innovations in the field of minimally invasive surgery, he is also a transplant surgeon.  In fact, along with his partners, he performed an average of 35 – 40 lung transplants a year.*  This makes the transplant program in Coruna the second largest in Spain, despite the relatively small size of Coruna compared to other cities such as Barcelona or Madrid.

I published an article based on this interview over at Examiner.com

* Spain is reported to have one of the highest rates of voluntary organ donation in the world.  According to data provided by the Organ Registry of Spain – there were 230 lung transplants in 2011.

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.

Relaxed roundtable discussion – Latin American surgeons. (Dr. Fernando Bello is the second from the left)

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.

SITS lobectomy with Dr. Diego Gonzalez

Discussion of a case report by Gonzalez, Paradela, Garcia & Dela Torre (2011) of a lobectomy by single incision thoracoscopic surgery.

Since there’s been quite a bit of interest in single-port thoracoscopic surgery (SITS) here at Cirugia de Torax.org  – I’ve added information about SITS lobectomy.  British surgeons, Rocco et. al  had previously reported the outcomes of several wedge resections by uni-port (SITS) back in 2004 but this is the first case report that I’ve seen for lobectomies via this technique*.

Gonzalez et al. in Coruna, Spain published a case report of a lobectomy by SITS.  The authors note that they have performed three cases by this technique at the time of article submission (November 2010).

As expected, the authors reported decreased post-operative pain and parathesias when using this technique.   They also reported that while visibility is more limited with this approach, they feel that it is less problematic for surgeons already accustomed to, and familiar with double port lobectomies.  This approach, in their experience, is best used for lower lobe lesions due to difficulties accessing and maneuvering for bronchial resection for upper lobectomies.

Update:  25 July 2011

I contacted Dr. Gonzalez to inquire about his surgical experiences since the publication of the article this past March.  Dr. Gonzalez reports that he and his colleagues (Dr. Mercedes De la Torre and Dr. Fernandez) have continued to practice SITS for lobectomies and other thoracic procedures, and that he is now using it for the majority of his cases.

Dr. Gonzalez states that many of his patients are discharged earlier (POD 2 or 3) and are experiencing less post-operative pain.  He is planning future studies to demonstrate this.

I expect we’ll be hearing more about Dr. Gonzalez and his partners in the future.

Note: Dr. Chu in Beijing, China has also published cases in the literature with single port lobectomies.
