Long-Term Results of Laparoscopic Sleeve Gastrectomy for Morbid Obesity: 5 to 8-Year Results.

Abstract

Although long-term results of sleeve gastrectomy (LSG) remain scarce in the literature, its popularity as a stand-alone procedure has accounted for a global increase in LSG performance. In this retrospective study, the authors present 5 to 8-year follow-up results in terms of weight loss, failure/revision rate, and comorbidity resolution from a single center. A prospectively maintained database was reviewed for patients who underwent LSG between 2007 and 2010. Data analysis on weight loss, comorbid conditions, revision surgery, and mortality was conducted. Median percentage excess BMI loss (%EBMIL) was 59.0, and 53.9%, and median percentage total weight loss (%TWL) was 25.1, and 22.9% at 5 and 8years, respectively. Revision to gastric bypass due to insufficient weight loss or gastroesophageal reflux disease (GERD) was performed in 42 patients (15.2%). Resolution of comorbid condition was achieved in 91% of patients with obstructive sleep apnea syndrome (OSAS), 68% of patients with type 2 diabetes (T2DM), 53% of patients with hypertension, and 25% of patients with dyslipedemia. Loss to follow-up rate was 45% at 5years, 28% at 6years, 23% at 7years, and 13% at 8years. This study adds to the currently available data confirming the LSG to be a safe and effective procedure at long term. Data from high-volume studies are needed to establish the definite role of the LSG in the spectrum of bariatric procedures.
