This study compared two laparoscopic sleeve gastrectomy (LSG) techniques. Technique B, involving stomach section before mobilization, showed trends towards shorter operative times and less bleeding than Technique A.

Area of Science:

  • Bariatric surgery
  • Minimally invasive surgery
  • Obesity treatment

Background:

  • Laparoscopic sleeve gastrectomy (LSG) is a modern restrictive bariatric procedure.
  • This study prospectively compares two distinct LSG surgical techniques.

Purpose of the Study:

  • To compare the efficacy and safety of two laparoscopic sleeve gastrectomy techniques.
  • To evaluate operative time, complications, and weight loss between techniques.

Main Methods:

  • A prospective randomized study involved 40 patients divided into two groups (A and B).
  • Technique A: stapling after full devascularization and mobilization. Technique B: stapling upon entering the lesser sac, followed by greater curve devascularization.
  • Staple-line reinforcement was performed in both techniques.

Techniques of Sleeve Gastrectomy and Modified Roux-en-Y Gastric Bypass in Mice

Published on: March 20, 2017

Main Results:

  • Median operative time was shorter in Technique B (25 min) vs. A (34 min).
  • Peroperative bleeding and hospital stay showed no significant difference between groups.
  • Excess weight loss (%EWL) at 1 year was comparable: 48.3% (A) vs. 49.5% (B).
  • Complications included hiatal hernia, bleeding, and one postoperative leak in Group A; one stenosis in Group B.

Conclusions:

  • LSG can be performed using two distinct techniques.
  • Technique B may offer advantages in operative time, bleeding, and hospital stay, though not statistically significant.
  • Both techniques demonstrate similar weight loss outcomes and acceptable complication rates.
