Standard acid reflux testing revisited

Digestive Diseases and Sciences

Abstract

Patients who present with uncontrolled esophageal acid reflux symptoms require endoscopy to determine the presence or absence of ulcers and stenoses, acid reflux testing to determine if acid reflux is present, and manometry to evaluate esophageal peristalsis and spastic states. These studies are usually done in stages, at separate times. Esophageal manometry catheters currently in use have an incorporated infusion channel. This allows instillation of a dilute acid meal after esophageal manometry has been completed. Standard acid reflux testing can then be done using dynamic positioning and physiologic maneuvers. When combined with an esophagogastroduodenas copy (EGD), these three studies provide all information necessary within 2-3 h to determine further treatment of these patients. A total of 210 patients underwent these studies. A hiatus hernia was present in 84%. An ineffective lower esophageal sphincter was found in 64%. Esophageal hypocontractility was present in 18%, hypercontractility in 14%, and dysmotility in 36%. Upper esophageal sphincter was weak in 42%, hypercontractile in 42%, and dysmotile in 32%. Acid reflux disease was found in the hiatus hernia in 14% and acid reflux to the level of the lower esophagus in 16%,...Continue Reading
