Impact of surgeon experience and buttress material on postoperative complications after laparoscopic sleeve gastrectomy.

Background: Sleeve gastrectomy is gaining popularity whether as a primary, staged or revisional operation. The aim of this study is to evaluate the perioperative safety and the learning curve for laparoscopic sleeve gastrectomy (LSG).

Methods: We performed a retrospective review of the prospectively collected data for all patients who underwent LSG for the treatment of morbid obesity at our institution from January 2003 to December 2008.

Laparoscopic sleeve gastrectomy--influence of sleeve size and resected gastric volume.

Background: Although the efficacy of laparoscopic sleeve gastrectomy (LSG) for morbidly obese patients with a BMI of <50 kg/m2, the incidence of weight gain by change of eating behaviors, and gastric dilatation following LSG have not been investigated thus far, LSG is becoming more common as a single-stage operation for the treatment morbid obesity.

Methods: This is a prospective study of the initial 120 patients who underwent isolated LSG. Initially, the LSG was performed without a calibration tube and resulted in high sleeve volumes (group 1: n=25).
