Abstract
A dilated gastrojejunal anastomosis (GJA) diameter is an independent predictor of weight regain following Roux-en-Y gastric bypass (RYGB). Despite this, there is no standardized method for GJA diameter measurement. We performed a retrospective analysis to compare endoscopic visual estimation and endoluminal functional impedance planimetry (EndoFLIP) for measuring GJA diameter in patients with weight regain post-RYGB. Visual estimation was found to overestimate GJA diameter by a mean of 4.2mm ± 4.6mm when compared with EndoFLIP. Furthermore, we identified symptomatic patients with normal GJA diameter but increased distensibility, which may represent a previously unrecognized subgroup. Our findings suggest the potential utility of EndoFLIP in the evaluation of post-RYGB weight regain and support the need for prospective studies to investigate the relationship between GJA distensibility and weight regain.
