To determine if Alvimopan during open or robotic radical cystectomy with urinary diversion results in quicker return of bowel function (GI-2 recovery = time to upper [first toleration of solid food] and lower [first bowel movement] gastrointestinal recovery) compared to placebo.


A prospective, randomized, single-center double blind trial of Alvimopan versus placebo for improving patient outcomes and cost during radical cystectomy and urinary diversion will be performed. A randomized trial is necessary to control for all the known and unknown confounders associated with instituting this novel intervention into a surgical procedure. We will recruit 136 subjects (63 patients in each arm of the study per sample size calculation below, plus additional 10 subjects to account for drop outs). A control group will be administered a placebo in order to directly compare if the Alvimopan intervention is effective.

Previous total colectomy, gastrectomy, or gastric bypass, or functional colostomy or ileostomy

Clinically significant laboratory abnormalities at screening that would have resulted in the cancellation of surgery
Using illicit drugs or abusing alcohol
History of previous surgeries, illness, or behavior (eg, depression, psychosis) that in the opinion of the investigator might have confounded the study results or might have posed additional risk in administering the study procedures
