ABSTRACT
BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) is emerging as a popular "stand-alone" bariatric procedure. We report our 5 years experience with LSG as a single-stage bariatric procedure with which to study the technical progress, learning curve, complications, and follow-up results. METHODS: Prospectively collected data of 228 patients (145 females and 83 males), who underwent LSG for morbid obesity, from February 2007 to March 2012, was retrospectively analyzed. RESULTS: The mean age was 34.68 years (range, 18-62 years) and the mean preoperative body mass index (BMI) was 37.42 ± 4.75 kg/m(2) (range, 32.08-65.69 kg/m(2)). Mean operative time was 60.63 ± 27.37 min. The mean BMI decreased to 26.15 ± 3.71 kg/m(2) at 3 years (p < 0.001) and to 27.94 ± 4.08 kg/m(2) at 5 years (p < 0.001). Mean percentage excess weight loss was 71.96 ± 21.30 % at 3 years and 63.71 ± 20.08 % at 5 years. The 30-day readmission rate was 3.07 %.Overall complication rate was 4.3 %, including strictures, leaks, peritonitis, gastrocutaneous fistula, and one (0.43 %) mortality. One patient with weight regain and another with stricture underwent conversion to Roux-en-Y gastric bypass. Complication rates significantly decreased after the first 50 cases (p = 0.022), suggesting an initial learning curve. Resolution of diabetes, hypertension, and hyperlipidemia was 66.67, 100, and 50 %, respectively, at 5 years. CONCLUSIONS: LSG as a single-stage bariatric procedure is safe and durable, achieving weight loss and resolution of comorbidities up to 5 years. Adherence to technical details is pivotal in reducing complications associated with the initial learning phase.
