Résumé
Gastrojejunal anastomosis (GJA) dilation is an independent predictor of weight regain (WR) after Roux-en-Y gastric bypass (RYGB). However, the role of planimetric measurements in this context remains unknown. This is a retrospective cohort study including adult RYGB patients who underwent a diagnostic endoscopy with Endoflip assessment of the GJA. We excluded patients in the early postoperative period and those with abnormal endoscopic findings (marginal ulcers and gastro-gastric fistulas). Thirty-four patients were initially included. Endoscopic GJA diameter had a moderate positive correlation with WR (r=+0.438, p=0.011). However, after excluding the 7 patients with GJA> 30 mm, there was no significant correlation. There was a moderate agreement between the EndoFLIP-GJA diameter at 60mL and endoscopic diameter (ICC=0.576, p=0.049). The distensibility index (DI) showed a consistent moderate negative correlation with WR. Considering the maximum DI at 40 ml, we found a cutoff of DI = 7 mm Visual estimation of the GJA diameter correlates with EndoFLIP at 60mL. In the subset of patients with GJA ≤ 30 mm, more distensible GJAs are associated with lower rates of WR. Larger studies are needed to confirm this correlation and to validate its utility for clinical management.
