High ‐resolution manometry findings in symptomatic post‐Nissen fundoplication patients with normal endoscopic configuration

Summary The aim of this study was to investigate high‐resolution manometry (HRM) findings in symptomatic post‐fundoplication patients with normal endoscopic configuration. A retrospective review of a prospectively maintained database was conducted to identify patients who underwent evaluation with HRM and endoscopy for symptom evaluation after previous fundoplication. Study period extends from September 2008 to December 2012. Only patients with complete 360° fundoplication (Nissen) were included, and patients with partial fundoplication were excluded. Patients with endoscopic abnormality or patients who underwent Collis procedure were also excluded. Additionally, contrast study and 24‐hour pH study if done were reviewed. Symptoms were graded using a standard questionnaire with symptoms graded on a scale of 0–3. Symptom grade 2 or 3 was considered a significant symptom. One hundred seventy‐nine symptomatic patients with previous Nissen fundoplication underwent HRM and endoscopy during the study period. Of these, 136 patients were excluded (51 had recurrent hiatal hernia, 2 had disrupted fundoplication, 68 had slipped fundoplication, 10 had twisted fundoplication, 2 had esophageal stricture, and 3 had Collis procedure). Remaining forty‐three patients met inclusion criteria (mean age of 56.0 ± 14.8, 32 females).The most common symptom was dysphagia (67%). Patients with dysphagia had a significantly longer length of distal esophageal high pressure zone (HPZ) and a h...
