Laparoscopic sleeve gastrectomy: Technique and results

Laparoscopic sleeve gastrectomy (LSG) has gained popularity as a stand-alone procedure. The objective of this study was to describe the surgical technique and evaluate the outcomes of LSG published in the literature. Twenty-six studies were analyzed with a one to fi ve year follow-up after LSG. Twenty-two of the twenty-six studies reported patient gender (n= 2765) and 69.1% of the patients were women. Mean age of the patients was 41.05 (22 studies, n= 2483 patients). Mean preoperative body mass index (BMI) in all twenty-four studies was 48.2 kg/m 2 (range: 2 37.2 to 65.3 kg/m 2 ). Overall mean percentage of excess weight loss (%EWL) after LSG was 2 reported 57.7% in seventeen studies. Postoperative complication rate ranged from 0% to 15.3%. Leak rate ranged from 0.7% to 5.1% and mortality rate ranged from 0% to 1.4%. Eleven studies showed remission rate of the postoperative co-morbidity data with a follow-up period of 12-60 months. Existing data have identifi ed that LSG is comparable to other accepted bariatric procedures but long-term data is limited.
