Perioperative Morbidity and Mortality of Laparoscopic Sleeve Gastrectomy (LSG) in a Single-Surgeon Experience on 892 Patients Over 11 Years

Abstract

BackgroundLaparoscopic sleeve gastrectomy (LSG) has been the most frequently performed bariatric procedure since 2014, with continually growing popularity. This study aimed to present our 30-day morbidity and mortality following LSG over a period of 11 years.Patients and methodsThis is a retrospective study that was based on prospectively collected data from patients undergoing LSG by the same surgeon from July 2011 to the end of August 2022. The LSG-associated 30-day morbidity and mortality and the risk factors for 30-day morbidity were assessed.ResultsThis study included 892 patients who underwent LSG over the course of 11 years. Early postoperative adverse events were encountered in 16 patients (1.79%). Overall, twelve patients (1.35%) required blood transfusions, and two patients (0.22%) required ICU admission. The re-operation rate was 0.9% (n = 8) and the mortality rate was 0.22% (n = 2). The patient’s BMI, hypertension, and revisional surgery were marginally significant/significant predictors of early postoperative morbidity. The mean EBWL% was 63.8 ± 15.55 at the 6-month follow-up.ConclusionThis study confirms the previously reported LSG's short-term safety in terms of a low rate of 30-day postoperative morbidity and mortality. Preoperative BMI, hypertension, and revisional surgery are risk factors for 30-day morbidity and mortality.
