From: Nature of antireflux barrier formed by Nissen fundoplication surgery
HREMZ pressure and impedance recordings during gastric distension with saline, at baseline, following Nissen and following Toupet fundoplication (A). Note, minimal changes in the EGJ pressure with rapid reflux of saline (purple) into esophagus at baseline. In contrast, note the augmentation of EGJ pressure during gastric distension, and delayed reflux of saline seen following Toupet and Nissen fundoplication. (B) Saline volume at the onset of reflux was higher following Nissen and Toupet fundoplication as compared to before fundoplication.
