Objective The purpose of the study was to test hypothesis that cardiac mucosa, carditis, and specialized intestinal metaplasia at an endoscopically normal-appearing cardia are manifestations gastroesophageal reflux disease. Summary Background Data In absence esophageal mucosal injury, diagnosis disease currently rests on 24-hour pH monitoring. Histologic examination esophagus is not useful. recent identification cardia, along with observation it occurs in inflamed led authors focus type...

To evaluate prospectively the outcome of laparoscopic fundoplication in a large cohort patients with typical symptoms gastroesophageal reflux.The development over past several years has resulted renewed interest surgical treatment reflux disease (GERD).One hundred GERD were studied. The study was limited to positive 24-hour pH studies and "typical" GERD. Laparoscopic performed when clinical assessment suggested adequate esophageal motility length. Outcome measures included relief primary...

All but nine 53 in whom a 24-hour pH study was performed had abnormal reflux, suggesting that endoscopic recognition an columnar mucosa at junction sufficient to precipitate multiple-level indicates high probability reflux. cardiac (CM) or oxyntocardiac (OCM).

To quantify the occurrence of intestinal metaplasia in columnar-lined esophagus (CLE) during endoscopic surveillance and to evaluate impact antireflux surgery on development metaplasia.The malignant potential segments CLE is mainly restricted those containing metaplasia. Patients with which no can be detected are rarely enrolled a program but may still at increased risk developing esophageal adenocarcinoma because missed or develop time.The biopsy samples was determined repeated endoscopies...

Heller's esophagomyotomy relieves dysphagia but does not restore esophageal peristalsis. The myotomy may induce reflux and the addition of a 360° fundoplication be hazardous with regard to remaining aperistaltic esophagus. aim this prospectively randomized clinical trial was compare outcome for patients uncomplicated achalasia who underwent an anterior (H group) or without additional floppy Nissen + N group).

OBJECTIVES Esophageal pH monitoring using a wireless capsule has been suggested to generate less adverse symptoms resulting in improved patient acceptance compared with the catheter-based method although evidence support this assumption is lacking. The aim of study was evaluate and compare subjective experience patients undergoing both techniques for esophageal monitoring. METHODS Using randomized design, referred testing underwent traditional 24-h recording 7-day interval. placed during...

A new wireless technique for oesophageal pH monitoring has recently been introduced (Bravo®). To implement this in clinical practice, values of normal acid exposure need to be defined a large age- and gender-matched healthy population. The aims study were investigate the feasibility safety establish exposure.
