Same day versus next day antroduodenal manometry results in children with upper gastrointestinal symptoms: A prospective study

Background We evaluated the changes in antroduodenal manometry (ADM) parameters and interpretation when the test is performed the day of catheter placement and the following day. Methods Catheter was placed endoscopically under anesthesia and recorded on day 1 and repeated on day 2. Study parameters including antrum and small bowel motility index (MI) during fasting, meal, postprandial, erythromycin (EES), and octreotide (OCT) challenge phases, the presence of the phase III of the migrating motor complex (MMC), visual postprandial response, and study interpretation were compared between both days. Key Results Twenty patients were studied. Antrum and small bowel MI during fasting, postprandial, and EES challenge phases were significantly higher on day 2 than on day 1 (P
