Alvimopan as a Rescue Treatment of Postoperative Ileus

• Status: Recruiting
• Trial end date: 2022-08-01
• Target enrollment: 0
• Participant gender: All

Summary

This study aims to evaluate the cost effectiveness of Alvimopan as rescue therapy in patients undergoing colorectal or small bowel resection who develop POI, and its safety and effectiveness in reducing LOS and POI duration.

This will be a prospective randomized control trial with a total of 58 patients, 29 in each group. Patients who undergo laparoscopic or open colorectal resection, small bowel resection, or ileostomy reversal with small bowel resection that subsequently develop postoperative ileus will be eligible for enrollment. If they meet inclusion/exclusion criteria, they will be randomized at the time of diagnosis of postoperative ileus to receive Alvimopan as rescue therapy or to receive conservative standard care.

Patients randomized to the study group will be given a maximum of 3 doses of Alvimopan 12mg orally, 12 hours apart. Alvimopan will be given from the time of diagnosis of postoperative ileus to the time of return of bowel function or the maximum 3 doses. Subsequent Alvimopan doses will be given if there is no return of bowel function or if symptoms of distension and/or nausea persist despite some return of bowel function.
