Abstract:
BACKGROUND/AIMS: The competency of the gastroesophageal junction (GEJ) holds the key in unlocking pathophysiologic mechanisms of gastroesophageal reflux disease (GERD). However, a relationship between GERD and the incompetent GEJ has not been established. The aim of our study was to assess the relationship between the shape of the GEJ and gastroesophageal acid reflux. METHODS: Forty six patients with reflux symptoms underwent an endoscopy, esophageal manometry and 24-hour esophageal pH monitoring. Patients were placed in 3 groups according to the shape of their GEJ, categorized by a retroflex view of the endoscopy; type I - gastroesophageal fold without a pouch, type II - no pouch and no fold, and type III - a pouch without a fold. RESULTS: In type II and III, LESP was reduced. However, % of time with the pH < 4.0 was increased in type III only. There was a significant correlation between the size of a hiatal hernia and the shape of the GEJ. There was a relationship between the grade of esophagitis and the shape of the GEJ. CONCLUSIONS: The retroflex endoscopic finding of the GEJ focusing on the presence or absence of a GE fold and hiatal pouch, could be an indicator of whether a patient has GERD.
