Geometry and reproducibility in 360° fundoplication

Background: In this study, we set out to precisely define two symmetrical points—a on the anterior fundic wall and b on the posterior fundic wall. These points, when advanced around a 60-Fr bougie-filled esophagus, will meet on the right side, to the right of the anterior vagus nerve, to create a reliable, reproducible, loose (i.e., or “floppy”) 360° fundoplication (FP).
