Abstract

Objective: We performed through-the-scope-manometry of the esophagus on 12 patients referred for esophageal symptoms. Methods: A 3-lumen polyvinyl tube was passed through the biopsy channel of a standard video-endoscope. All patients underwent esophagogastroduodenoscopy with through-the-scope- manometry as well as a conventional laboratory-based manometric study; the sequence of the procedures was randomized. Results: Mean lower esophageal sphincter pressure was 18 ± 11 mm of mercury by both methods. In the lower esophagus, mean wave amplitude was 60 ± 25 mm of mercury by through-the- scope manometry and 82 ± 28 by laboratory testing. In the upper esophagus, mean wave amplitude was 50 ± 26 mm of mercury by through-the-scope manometry and 63 ± 20 by laboratory testing. Wave duration tended to be lower by through-the-scope manometry than by laboratory testing in the lower and upper esophagus. In nine patients with normal esophageal motility, 54% of swallows resulted in a peristaltic wave by the endoscopic study versus 100% for the laboratory test. Conclusion: Through-the-scope-manometry was able to accurately measure lower esophageal sphincter pressure compared with laboratory-based manometry. Peristaltic wave amplitude by through-the-scope manometry was reduced compared with laboratory-based manometry, most likely because of the use of dry swallows. Through-the-scope-manometry has promise as a screening test for esophageal motility disorders.
