Abstract

In Brief Objective: To conduct a systematic review to identify surgical strategies that may decrease leak after laparoscopic sleeve gastrectomy (LSG). Background: LSG is growing in popularity as a primary bariatric procedure. Technical aspects of LSG including bougie size remain controversial. Methods: Our systematic review yielded 112 studies encompassing 9991 LSG patients. A general estimating equation (GEE) model was used to calculate the odds ratio (OR) for leak based on bougie size, distance from the pylorus, and use of buttressing on the staple line. Baseline characteristics, including age and body mass index (BMI), were included. A linear repeated measures regression model compared excess weight loss (%EWL) between bougie sizes. Results: A total of 198 leaks in 8922 patients (2.2%) were identified. The GEE model revealed that the risk of leak decreased with bougie ≥40 Fr (OR = 0.53, 95% CI = [0.37–0.77]; P = 0.0009). Buttressing did not impact leak. There was no difference in %EWL between bougie <40 Fr and bougie ≥40 Fr up to 36 months (mean: 70.1% EWL; P = 0.273). Distance from the pylorus did not affect leak or %EWL. Conclusions: Utilizing bougie ≥40 Fr may decrease leak without impacting %EWL up to 3 years. Distance from the pylorus does not impact leak or weight loss. Buttressing does not seem to impact leak; however, if surgeons desire to buttress, bioabsorbable material is the most common type used. Longer-term studies are needed to definitively determine the effect of bougie size on weight loss after LSG. Our meta-analysis of 9991 laparoscopic sleeve gastrectomy cases reveals that utilizing bougie ≥40 Fr may decrease leak without significantly impacting weight loss up to 3 years. Distance from the pylorus does not impact leak or weight loss. Staple-line buttressing does not seem to impact leak rate.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
