Brief summary
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
PROCEDURELaparoscopic 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.
PROCEDURELaparoscopic 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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Postoperative gastric leak rate | 30 days following the procedure | Postoperative gastric leak rate during the first month following the procedure will be proven either on: * Morphologic examination (with contrast ingestion) * Blue dye test during surgical reintervention or postoperative course * Contrast opacification during endoscopy |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Postoperative morbidity rate | 90 days following the procedure | Postoperative morbidity rate will be calculated regarding any complication occurring 90 days following the procedure. |
| Short-term weight loss | At 3 and 6 months after the procedure | Short-term weight loss will be assessed by calculation of excess weight loss at 3 and 6 months after the procedure. |
| Mid-term weight loss | At 1 and 2 years after the procedure | Mid-term weight loss will be assessed by calculation of excess weight loss at 1 and 2 years after the procedure. |
| Quality of life related to health | At 3 months, 6 months, 1 year and 2 years after the procedure | Quality of life related to health will be assessed at 3 months, 6 months, 1 year and 2 years after the procedure with the validated GIQLI scale (Gastro Intestinal Quality of Life Index) |
