Long-term outcomes of laparoscopic sleeve gastrectomy: a Lebanese center experience

Abstract

Background Long-term data of laparoscopic sleeve gastrectomy (LSG) are still scarce in the Middle East. Objectives The aim of this study was to assess the efficacy and safety at 5 years and beyond. Setting Tertiary referral hospital between April 2007 and March 2015. Methods A retrospective review of 76 patients who underwent LSG at the senior author's institution between April 2007 and March 2010. Results Mean preoperative body mass index (BMI) was 42.8±7.1 kg/m2. Follow-up rates were 90.4%, 86.3%, and 77.8% at 5, 6, and 7 years, respectively. Percentage of excess weight loss (%EWL) was 69.8%±28.7% at 5 years, 70.6%±32.7% at 6 years, and 76.6%±21.2% at 7 years, respectively. Mean total weight loss was 26.5%±8.7%, 24.9%±8.8%, and 26.6%±6.0% at 5, 6, and 7 years, respectively. %EWL at 5-years was significantly higher for patients with a preoperative BMI<45 kg/m2 (83.1% versus 46.3%, P <45 kg/m2. De novo acid reflux symptoms developed in 1 of 5 patients. Cholelithiasis necessitating cholecystectomy was the most common long-term complication.
