Comparative Study Between the Outcomes of Laparoscopic Sleeve Gastrectomy and Mini Gastric Bypass for Morbidly Obese Patients

Abstract

Article information Background: Obesity has become a global epidemic, and bariatric surgery has emerged as an effective treatment for morbidly obese individuals. Laparoscopic sleeve gastrectomy [LSG] and mini gastric bypass [MGB] are two commonly performed procedures with distinct mechanisms of action and outcomes. Aim of the work: This comparative study aims to evaluate and compare the outcomes of LSG and MGB in morbidly obese patients, focusing on weight loss, depression improvement, early complications and blood glucose. Patients and Methods: A prospective interventional study included 40 consecutive morbid obese patients who underwent bariatric surgery [LSG or MGB]. The effects of both procedures on weight loss outcomes, the severity of depression, blood glucose and laboratory parameters were evaluated over six-months duration. Results: Both procedures demonstrated similar effectiveness in reducing weight and lowering random blood sugar levels during the planned follow-up appointments. In the case of LSG, the percentage of excess weight loss [%EWL] had average figures of 13.64%, 34.2%, and 59.52%, while for LMGB, it was 13.42%, 42.96%, and 58.91% at the 1-month, 3-month, and 6-month follow-up visits, respectively. There was a notable decrease in reported depression scores after six months, with no significant variance observed between the two procedures. Conclusion: Both procedures were associated with a similar reduction in body weight and percentage of excess weight loss, improvement in blood glucose levels, and depression scores.
