Abstract

BACKGROUND/AIMS
The study aimed to determine pre- and post-fundoplication esophagogastric junction (EGJ) pressure and esophageal peristalsis by high-resolution manometry (HRM) in patients with gastroesophageal reflux disease (GERD).
METHODS
Pre-operative and post-operative HRM data from 25 patients with GERD were analyzed using ManoView version 2.0.1. with updated software for Chicago classification and pressure topography. The study involved swallowing water boluses of 10 mL in the upright position.
RESULTS
Significant increase of mean basal EGJ pressure and minimal basal EGJ pressure was found in post-operative as compared with preoperative patients (P < 0.05 and P < 0.001, respectively). Integrated relaxation pressure (IRP) reached higher values in post-operative patients than in pre-operative patients (P < 0.001). Intra-bolus pressure (IBP) was significantly higher (P < 0.05) and contractile front velocity (CFV) was slower (P < 0.01) in post-operative patients than in pre-operative patients. Moreover significant increase of distal contractile integral (DCI) was found in post-operative patients (P < 0.05). Hiatal hernia was detected by HRM in 11 pre-operative patients. Fifteen out of 25 post-operative patients complained of dysphagia.
CONCLUSIONS
Fundoplication restores the antireflux barrier by reinforcing EGJ basal pressures, repairing hiatal hernias, and enhances peristaltic function of the esophagus by increasing DCI. However slight IRP elevation found in post-fundoplication patients may result in bolus pressurization and motility disorders.
