Laparoscopic Banded Sleeve Gastrectomy: Single-Center Experience with a Four-Year Follow-Up.

ABSTRACT

Introduction: Laparoscopic sleeve gastrectomy (LSG) is now the most common bariatric procedure to treat morbidly obese patients. The main concern of LSG lies in the long-term weight regain, which is reported to happen in up to 75.6% of patients after 6 years. In this study, we report our overall experience with Laparoscopic Banded Sleeve Gastrectomy (LBSG) using the MiniMizer® over a 6-year period. Materials and Methods: We performed a retrospective review of data from a prospectively collected database. All patients submitted to primary LBSG were examined. Patients were submitted to LBSG between February 2014 and January 2020. Collected data included demographic factors, preoperative body mass index (BMI), operative time, surgical complications, and clinical outcomes. Results: Two hundred nine patients were submitted to primary LBSG in the study period. They were 136 females (65%) and 73 males (35%) with a median age of 43.0 years (range, 18-65 years). Median preoperative BMI was 48.4 kg/m2 (range, 36.2-65.5 kg/m2). Median operative time was 72.0 minutes (range, 40-142 minutes). Median time for ring placement was 8.0 minutes. Median postoperative hospital stay was 2.8 days. Seven major complications occurred in the postoperative period (3.3%) five gastric leaks (2.3%) and two major bleedings (0.9%). There was no postoperative mortality in the 209 patients. Long-term major complications occurred in 2 patients (0.9%). Median follow-up was 49.2 months (range, 2-72 months). Median postoperative BMI was 29.6 kg/m2 (range, 22-42 kg/m2). Median %excess weight loss (%EWL) at 1 year after surgery was 52.0%. Median %EWL at last follow-up visit was 64.0%. Conclusion: LBSG is as safe as standard LSG with excellent results in terms of postoperative morbidity and weight loss outcomes. Whether this procedure may result superior to standard LSG in the long-term period needs to be evaluated in randomized trials. Clinical Study Registration Number NCT04354532.
