Abstract

Introduction: The use of alvimopan at the time of cystectomy has been associated with improved perioperative outcomes. Naloxegol is a less costly alternative that has been used in some centers. This study aims to compare the perioperative outcomes of patients undergoing cystectomy with urinary diversion who receive the mu-opioid antagonist alvimopan versus naloxegol.
Materials and methods: This was a retrospective review that included all patients who underwent cystectomy with urinary diversion at our institution between 2007-2020. Comparisons were made between patients who received perioperative alvimopan, naloxegol and no mu-opioid antagonist (controls).
Results: In 715 patients who underwent cystectomy, 335 received a perioperative mu-opioid antagonist, of whom 57 received naloxegol. Control patients, compared to naloxegol and alvimopan patients, experienced a significantly (p < 0.05) delayed return of bowel function (4.3 vs. 2.5 vs. 3.0 days) and longer hospital length of stay (7.9 vs. 7.5 vs. 6.5 days), respectively. The incidence of nasogastric tube use (14.2% vs. 12.5% vs. 6.5%) and postoperative ileus (21.6% vs. 21.1% vs. 13.3%) was also most common in the control group compared to the naloxegol and alvimopan cohorts, respectively. A multivariable analysis revealed that when comparing naloxegol and alvimopan, there was no difference in return of bowel function (OR 0.88, p = 0.17), incidence of postoperative ileus (OR 1.60, p = 0.44), or hospital readmission (OR 1.22, p = 0.63).
Conclusions: Naloxegol expedites the return of bowel function to the same degree as alvimopan in cystectomy patients. Given the lower cost of naloxegol, this agent may be a preferable alternative to alvimopan.
