Exploring alternative techniques for laparoscopic sleeve gastrectomy with stapling first: the in situ method in a propensity score-matched retrospective study

Purpose

Laparoscopic sleeve gastrectomy (LSG) is the most common metabolic and bariatric surgery worldwide. However, achieving adequate exposure at the angle of His remains technically challenging. This study introduces a modified "in situ" method, hypothesizing shorter operative time without increased complications or compromised 1-year weight loss.

Methods

This retrospective analysis included primary LSG (in situ or conventional method) performed between July 2019 and January 2022. Propensity score matching was applied to address sample size imbalance and ensure comparability. Perioperative outcomes, operative time, and 1-year weight loss of the 2 groups were compared.
