Relevance of ineffective esophageal motility with erosive and nonerosive gastroesophageal reflux disease.

چکیده
INTRODUCTION Ineffective esophageal motility (IEM) is a frequent finding in patients with gastroesophageal reflux disease (GERD). It is responsible for delayed acid clearance as it affects esophageal emptying and saliva transport. Since erosive GERD is a more severe disease than nonerosive GERD, it may be associated with IEM, which delays esophageal clearance. Objective : We investigated the role of IEM in patients with erosive and nonerosive GERD. METHODS We enrolled 100 patients with heartburn and a primary diagnosis of GERD referred to the GI motility department of RCGLD of Shahid Beheshti University between January 2002 and January 2005. Based on endoscopic findings, the patients were classified into two groups of erosive GERD and nonerosive GERD. Manometry and 24-hour ambulatory pH-metry was performed in all patients. RESULTS Seventy-seven patients completed the study: 31 (40.3%) with erosive GERD and 46 (59.7%) with nonerosive GERD. IEM was present in 38.7% of patients with erosive GERD and in 28.3% of those with nonerosive GERD (p=0.18). A low lower esophageal sphincter pressure was present in 45.2% of patients with erosive GERD, and in 45.7% of those with nonerosive GERD (p=0.97). Abnormal acid reflux was present in 32.3% and 41.3% of patients with erosive and nonerosive GERD, respectively (p=0.42). CONCLUSION There was no difference in the prevalence of IEM between patients with erosive and nonerosive GERD. IEM could be an integral part of GERD and may not always be associated with mucosal injury.

Background/Aims Evaluation of esophageal clearance by orange juice swallowing could be useful to identify different categories of gastroesophageal reflux disease. We determined whether a juice test at the beginning of esophageal pH monitoring can identify nonerosive reflux disease (NERD) among heartburn patients. Methods Multiple swallows of orange juice (pH 3) were performed at the beginning...

Gastroesophageal reflux disease (GERD) is a highly prevalent gastrointestinal disorder. Proton pump inhibitors have profoundly revolutionized the treatment of GERD. However, several areas of unmet need persist despite marked improvements in the ther-apeutic management of GERD. These include the advanced grades of erosive esophagitis, nonerosive reflux disease, main-tenance treatment of erosive ...

Background/Aims Little data exists about esophageal body dysmotility and reflux patterns in refractory gastroesophageal reflux disease (RGERD) patients off therapy. We aimed to evaluate effects of esophageal body dysmotility on reflux parameters in RGERD patients by combining impedance-pH monitoring and high-resolution manometry (HRM). Methods We retrospectively reviewed the impedance-pH data...
