Comparison of the endoscopic aspect of the cardia, manometry and 24 hours pH measurement in patients with chronic gastroesophageal reflux. Santiago de Chile. Background: The endoscopic view of the gastric cardia could be related with the manometric competence of the lower esophageal sphincter LES and with pathological gastroesophageal reflux.

Aim: To compare the endoscopic aspect of the cardia with the results from esophageal manometry and 24 h esophageal pH monitoring. Materials and Methods: The cardia of a group of patients aged 19 to 72 years, 89 women with gastroesophageal reflux symptoms was classified as normal or open, during upper gastrointestinal endoscopy. All subjects were subjected to a manometric study to measure LES pressure and determine LES incompetence and to a 24 h esophageal pH measurement. Results: LES pressure was Conclusions: The endoscopic appearance of the cardia can identify patients with pathological gastroesophageal reflux.
