Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Staple-line leak is the most frequent and incapacitating complication after laparoscopic sleeve gastrectomy (LSG). The aim of this prospective randomized trial is to compare the staple-line leak rate after LSG according to the use of a standard bougie calibre (34, 36 or 38 Fr) or 48-Fr, assuming that a higher diameter is correlated with a lower risk of leak, without lowering long-term weight loss.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Laparoscopic sleeve gastrectomy (LSG) has become an increasing bariatric procedure. The most common complication is gastric leak from the staple line, observed in approximately 3% of cases, and can result in long and incapacitating treatment. The diameter of the bougie used to calibrate the remnant stomach could impact the rate of gastric leak, a higher diameter being correlated with a lower risk of leak, without lowering long-term weight loss.

The aim of this prospective randomized trial is to compare the outcomes of LSG according to the use of a standard care bougie calibre or 48-Fr on postoperative gastric leak and mid-term weight loss.

Laparoscopic sleeve gastrectomy using 48-Fr bougie

Patients will undergo laparoscopic sleeve gastrectomy with a 48-Fr (16 mm) bougie

Group Type EXPERIMENTAL

Laparoscopic sleeve gastrectomy using 48-Fr bougie

Intervention Type PROCEDURE

After gastric mobilization, the 48-Fr bougie is inserted through the mouth by the anesthesiologist and positioned in the stomach. Patient is blind to the type of bougie used. Gastrectomy is performed alongside the calibration bougie.

Laparoscopic sleeve gastrectomy using standard care bougie

Patients will undergo laparoscopic sleeve gastrectomy with a standard care bougie (34, 36 or 38-Fr)

Group Type ACTIVE_COMPARATOR

Laparoscopic sleeve gastrectomy using standard care bougie

Intervention Type PROCEDURE

After gastric mobilization, the standard care bougie is inserted through the mouth by the anesthesiologist and positioned in the stomach. Patient is blind to the type of bougie used. Gastrectomy is performed alongside the calibration bougie.
