Mauricio Velasquez – Thoracic Surgery

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.

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.

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.
