Study of Alvimopan for the Management of Opioid-induced Postoperative Bowel Dysfunction/Postoperative Ileus

Overview

Patients undergoing major abdominal surgery are at highest risk for developing Postoperative Ileus (POI), occurring in nearly all cases. Signs and symptoms of POI may include abdominal distention and bloating, persistent abdominal pain; nausea and/or vomiting; variable reduction of bowel sounds; delayed passage of or inability to pass flatus or stool; and inability to tolerate a solid diet. This study will test the ability of alvimopan 12 mg given 30 to 90 minutes before the scheduled start of surgery to hasten the recovery of GI function in patients having partial small or large bowel resections.

Postoperative ileus (POI) can be thought of as temporary slowing down or stopping of bowel function and a slowing down of movement of contents of the intestines. Patients undergoing major abdominal surgery are at highest risk for developing POI, occurring in nearly all cases. Signs and symptoms of POI may include abdominal distention and bloating, persistent abdominal pain; nausea and/or vomiting; variable reduction of bowel sounds; delayed passage of or inability to pass flatus or stool; and inability to tolerate a solid diet. This study will test the ability of alvimopan 12 mg given 30 to 90 minutes before the scheduled start of surgery to hasten the recovery of GI function in patients having partial small or large bowel resections.
