Laparoscopic Sleeve Gastrectomy as Treatment for Morbid Obesity: Technique and Short-Term Outcome

Background: Laparoscopic Roux-en-Y gastric bypass (LRYGBP) and laparoscopic adjustable gastric banding (LAGB) are the most commonly performed surgical procedures for weight reduction in the United States. Currently, laparoscopic sleeve gastrectomy (LSG) is being explored. The aim of this study was to assess the safety and short-term efficacy of LSG as a treatment option for weight reduction. Methods: Data of all patients who underwent LSG for treatment of morbid obesity between November 2004 and March 2006 and completed the 3- and 6-month follow-up visits at the time of the study, were retrospectively reviewed. Data collected included demographics, operative time, length of stay, postoperative complications, and degree of weight reduction. Results: Of the 62 patients who underwent LSG performed by two surgeons, the data of 30 patients (7 males and 23 females) were further analyzed. Mean preoperative BMI was 41.4 (33-59) kg/m². Mean operative time was 80 min (range 65-130). Mean hospital stay was 3.2 days (range 2 to 25). Mean weight loss at 3 and 6 months following the procedure was 22.7 kg and 30.5 kg respectively, and mean % excess weight loss (EWL) was 40.7 and 52.8, respectively. Three patients were considered to have mild complications, and one patient had a major complication that necessitated surgical intervention. There was no mortality. Conclusions: In the short-term, LSG is a safe and effective treatment option.
