Single-Center Experience of 500 Cases of Laparoscopic Sleeve Gastrectomy: Surgical Techniques and Perioperative Management Strategies.

Abstract

Introduction: Reported results and techniques of laparoscopic sleeve gastrectomy (LSG) are variable. Our objective was to assess results of weight loss, complications, and reflux in a large consecutive series of LSG, describing technical detail which contributed to outcomes. Methods: Retrospective review of prospectively collected data of 500 consecutive patients undergoing LSG. Patient demographics, weight loss, complications, and functional outcomes were analyzed and operative technique described. Results: Five hundred patients underwent LSG over 3 years (2 revisional). Mean (range) preoperative body mass index was 40 kg/m2 (32-75 kg/m2). Mean follow-up and length of hospital stay were 12 months (1-36) and 7.2 days (5-12), respectively. All-cause 30-day readmission rate was 0.3%. Mean excess weight loss was 22.3% (1 month), 42.2% (3 month), 57.2% (6 month), and 73.1% (1 year). There was no mortality and intraoperative complications occurred in our 500 cases. Early surgical complications in 2 (0.2%) patients (postoperative bleeds). Gastro-oesophageal reflux symptoms decreased about 10%. Conclusion: With attention to detail, LSG can lead to good excess weight loss with minimal complications. Tenants to success include repair of hiatal laxity, generous width at angula incisura, and complete resection of posterior fundus.
