Alvimopan Versus Placebo in Patients Undergoing Radical Cystectomy on an Enhanced Recovery Protocol

Официальное название

A Randomized, Double-blind, Single-Center Trial of Alvimopan (Entereg) Versus Placebo in Patients Undergoing Radical Cystectomy and Urinary Diversion on an Enhanced Recovery After Surgery ERAS Protocol

Обзор

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.

Подробное описание

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.

Вмешательства

• Препарат Alvimopan
  To determine if Alvimopan during radical cystectomy with urinary diversion results in faster return of bowel function.
• Препарат Placebo
  To determine if placebo during radical cystectomy with urinary diversion results in faster return of bowel function.
