Laparoscopic Sleeve Gastrectomy for Morbid Obesity with Intra-operative Endoscopy: Lessons We Learned After 100 Consecutive Patients.

Background: Sleeve gastrectomy has become the second most common bariatric operation due to its low rates of morbidity and mortality, satisfactory treatment of patients' obesity, and resolution of associated co-morbidities. According to standard technique, calibration of the stomach is performed with varying sizes of bougies while use of intra-operative endoscopy has only sparsely been reported.

Methods: Between 2004 and 2013, 100 patients have undergone laparoscopic or robotic sleeve gastrectomy with intra-operative endoscopic guidance. Technical aspects of the operation, results concerning morbidity, progressive weight loss, and resolution of co-morbidities were retrospectively reviewed.

Results: Morbidity and mortality was zero. Rates of excess weight loss at 6 months and 1 and 3 years were 52.1, 67.4, and 61.3 %, respectively. Patients' highest rate of excess weight loss was achieved 18 months post-operatively. These rates were inversely related with preoperative age, body mass index, and the existence of preoperative co-morbidities.

Conclusion: Sleeve gastrectomy with intra-operative endoscopic guidance is at least as safe and effective as with the bougie. Given the available expertise and equipment, the use of this technique can increase the intra-operative sense of safety with no compromise or even improvement of the immediate or long-term results.
