Summary

Metabolic and bariatric surgery (MBS) outcomes, including laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB), showed no significant 24-month weight loss differences. Standardized care and follow-up are key factors in successful MBS results.

Area of Science:

  • Bariatric Surgery
  • Weight Management
  • Surgical Outcomes

Background:

  • Adherence to multidisciplinary follow-up is crucial for long-term weight loss post-metabolic and bariatric surgery (MBS).
  • Preoperative assessment and surgical technique selection may influence outcomes, potentially explaining differences between laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB).

Purpose of the Study:

  • To compare 24-month weight outcomes for LSG and LRYGB within a standardized preoperative and multidisciplinary follow-up framework.
  • Evaluate the efficacy of different MBS procedures under consistent clinical management.

Main Methods:

  • Retrospective comparative cohort study of 71 patients undergoing MBS (LSG: n=45, LRYGB: n=26) between January 2021 and December 2023.
  • Outcomes assessed included percentage of total weight loss (%TWL), percentage of excess weight loss (%EWL), insufficient weight loss, and weight regain at 6, 12, 18, and 24 months.

Main Results:

  • At 24 months, no significant differences were found between LSG and LRYGB in %TWL (29.9% vs. 30.8%) or %EWL (61.6% vs. 63.4%).
  • Insufficient weight loss decreased from 21.1% at 6 months to 9.9% at 12 months.
  • Weight regain at 24 months occurred in 25.4% of patients, with no significant procedural differences.

Conclusions:

  • Under standardized preoperative selection and strict multidisciplinary follow-up, LSG and LRYGB demonstrate comparable 24-month weight loss outcomes.
  • Patient selection, follow-up adherence, and institutional factors likely contribute to MBS success, warranting further investigation into their specific impacts.
