An analysis of weight loss failure and weight regain in patients undergoing laparoscopic sleeve gastrectomy

Abstract

Introduction: The present study evaluates the weight regain (WR) and weight loss failure at the end of 4 years in patients undergoing laparoscopic sleeve gastrectomy (LSG). Materials and Methods: The data of patients who underwent a LSG in a single center for the treatment of morbid obesity were reviewed and analyzed retrospectively. Body mass index (BMI) was measured before surgery in all patients. The patients underwent a control examination and BMI measurement at 1, 2 3, and 4 years. The data were analyzed using the Statistical Package for the Social Sciences. Results: A total of 179 patients were included in the study. The proportion of male patients was significantly higher in the group of patients who re-gained weight than in those who did not re-gain weight at the end of 4 years. The rate of smokers was lower in the group of patients who re-gained weight than those who did not re-gain weight at the end of 4 years (p<0.05). Conclusion: The short- and long-term results of the present study suggest that LSG is an effective bariatric surgery procedure. WR was at the lowest levels in the first 3 years after LSG, but showed a progressive in- crease at the end of 4 years
