Correlation Between Gastrojejunal Anastomosis Diameter, Distensibility Index, and Weight Regain After Roux-en-Y Gastric Bypass.

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.
