Dr. Diego Gonzalez Rivas discusses non-intubated thoracic surgery

One of the standout presentations on Day One of the Duke Masters of Minimally Invasive Thoracic Surgery was Dr. Diego Gonzalez Rivas’ presentation on performing uniportal surgery on non-intubated patients. Surprisingly, this presentation was greeted with significant skepticism in the form of comments by fellow presenters.

The use of one small 2.5 cm incision with the camera placed above the instruments allows the surgeon to maintain the traditional perspective of open surgery using a minimally invasive approach.  “Eyes above hands” Dr. Gonzalez states, reminding surgeons how to keep their visual perspective unaltered.  He also discussed some of the findings from an upcoming 2016 paper [in-press] entitled, “Pushing the envelope” which reviews the developments in the areas of single port (uniportal) thoracic surgery in non-intubated patients. This along with his new textbook, have dominated the international thoracic surgery news in recent years.

As part of his discussion, he demonstrated the ease and feasibility of performing a complete and thorough lymph node dissection using the uniportal approach.

He also presented several complex thoracic cases such as a bronchial sleeve resection for carcinoid tumor in a young, otherwise healthy female, as well as a double sleeve case, and a uniportal bronchovascular reconstruction.  He discussed distal tracheal resection using high frequency ventilation jet in a non-intubated patient after resecting the carina – tracheal anastamosis and several chest wall resection cases via the uniportal approach.  But the main portion of his talk was devoted to the specifics of non-intubated surgery – from anesthesia protocols to creating a anatomic (surgical) pneumothorax which eliminates problems of lung inflation during surgery.  He discussed that while totally awake nonintubated surgery can be performed (with patients awake and talking), that he prefers the use of conscious sedation for patient comfort.

He highlighted the benefits of these approaches – with non-intubated surgical techniques allowing surgeons to operate on frailer, sicker patients who might otherwise be ineligible for surgery.  He also talked about the benefits of uniportal surgery versus robotic surgery.  Uniportal surgery is faster, and cheaper than costly robotic techniques that require lengthy patient positioning as well as the use of robotic tools that have to be replaced after 10 to 20 cases.

He also reviewed the relative contraindications for nonintubated surgery:

obese patients (BMI greater than 35)

patients with Malpati scores of 3 or 4 (difficult to intubate patients – in case of the need for emergent intubation)

patients with pulmonary hypertension (who will not tolerate permissive hypercapnia)

Masses greater than 6 cm in size

But he also reminded attendees that relative contraindications often change in the face of more experience.
