Abstract

Primary outcome of type 2 diabetes mellitus remission shows a 15% advantage for vertical sleeve gastrectomy over Roux-en-Y gastric bypass.

Vertical sleeve gastrectomy (VSG) is associated with higher remission rates for type 2 diabetes mellitus (T2DM) compared to Roux-en-Y gastric bypass (RYGB).
Hypertension remission is also more favorable with VSG, showing a 7% advantage.
Dyslipidemia remission rates are 16% greater with VSG than with RYGB.
Post-surgery body mass index (BMI) measurements indicate a slight advantage for RYGB.
Total cholesterol and LDL levels show significant improvements with RYGB, with 65% and 69% advantages, respectively.

Introduction: Obesity's associated comorbidities and treatment costs have risen significantly, highlighting the importance of early weight loss strategies. Bariatric surgeries like Roux-en-Y gastric bypass (RYGB) and vertical sleeve gastrectomy (VSG) have been effective in promoting weight loss and improving type 2 diabetes mellitus (T2DM) management. Aim: The aim was to determine whether Roux-en-Y gastric bypass is more effective than vertical sleeve gastrectomy in the remission of type 2 diabetes mellitus (T2DM). Methods: A systematic review and meta-analysis was performed. A literature search was performed in the databases Web of Science, Medline/PubMed, Embase, Scopus, and Medline/Ovid. A total of 1323 results were identified; after screening, 14 articles were selected and included in the systematic review. Primary and secondary outcomes were measured by RR with a 95% CI. Results: The primary outcome of T2DM remission was 15% in favor of VSG (RR: 1.15, [95% CI: 1.04-1.28]). For secondary outcomes, hypertension remission was 7% in favor of VSG (RR: 1.07, [95% CI: 1.00-1.16]). Remission of dyslipidemia was 16% in favor of VSG (RR: 1.16, [95% CI: 1.06-1.26]). BMI after surgery was in favor of RYGB (MD: -1.31, [95% CI: -1.98 to -0.64]). For weight loss, the results favored VSG (MD: 6.50, [95% CI: 4.99-8.01]). In relation to total cholesterol, they were 65% favorable for RYGB (MD: -0.35, [95% CI: -0.46 to -0.24]), with a value of p <0.05. For LDL values, our results were 69% favorable for RYGB (MD: -0.31, [95% CI: -0.45 to -0.16]), p <0.01 value. Conclusions: Laparoscopic sleeve gastrectomy is more effective in T2DM remission, hypertension remission, dyslipidemia remission, and weight loss compared to Roux-en-Y gastric bypass. Roux-en-Y gastric bypass is more effective at lowering BMI, total cholesterol, LDL, and TG compared to laparoscopic sleeve gastrectomy.</br&gt.
