Official title

Multicentric Randomized Prospective Study Assessing the Impact of the Bougie Calibration Size During Laparoscopic Sleeve Gastrectomy on the Rate of Postoperative Staple-line Leak Rate

Overview

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

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.

Interventions

  • Procedure Laparoscopic sleeve gastrectomy using 48-Fr bougie
    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.
  • Procedure Laparoscopic sleeve gastrectomy using standard care bougie
    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.

Primary outcome measures

  • Postoperative gastric leak rate [Time frame: 30 days following the procedure]
Secondary outcome measures (4)
  • Postoperative morbidity rate [Time frame: 90 days following the procedure]
  • Short-term weight loss [Time frame: At 3 and 6 months after the procedure]
  • Mid-term weight loss [Time frame: At 1 and 2 years after the procedure]
  • Quality of life related to health [Time frame: At 3 months, 6 months, 1 year and 2 years after the procedure]

Eligibility criteria

Inclusion criteria
