Antroduodenal manometry: An evaluation of an emerging methodology

Antroduodenal manometry is a relatively new technique for the assessment of gastric and small intestinal motor function. The aim of this review is to provide an evaluation of its current status as a diagnostical tool. Available recording systems are reviewed and the study protocol for the evaluation of antroduodenal motor function is described. The role of this methodology in the evaluation of patients with suspected motor disorders, its advantages over other less invasive techniques and limitations are critically assessed. We conclude that, in the evaluation of suspected foregut motor dysfunction, antroduodenal manometry may provide clinically useful information in selected patients; information which may not be available from standard diagnostic tests, including nuclear medicine gastric-emptying studies.
