Abstract

Introduction: 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.

Materials and methods: 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.

Results: 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 8 years, 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 5 years, 28 % at 6 years, 23 % at 7 years, and 13 % at 8 years.

Conclusion: 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.
