title: Opioid use is not associated with incomplete wireless capsule endoscopy for inpatient or outpatient procedures.
abstract: Objective. Wireless capsule endoscopy (WCE) is commonly used to directly visualize the small bowel. Opioids have variably been linked with incomplete studies and prolonged transit times in heterogeneous cohorts. We aimed to investigate the effect of opioid use on WCE for inpatient and outpatient cohorts. Methods. We performed a retrospective review of patients receiving WCE at our institution from April 2010 to March 2013. Demographic data, medical history, and WCE details were collected. Transit times were compared by log-rank analysis. Multivariable logistic regression and Cox proportional hazard models were utilized. Results. We performed 314 outpatient and 280 inpatient WCE that met study criteria. In the outpatient cohort, gastric transit time (GTT) was not significantly different between opioid and nonopioid users. Completion rates were similar as well (88% and 87%, P = 0.91). In the inpatient cohort, GTT was significantly longer in patients receiving opioids than in patients not receiving opioids (44 versus 23 min, P = 0.04), but completion rates were similar (71% versus 75%, P = 0.31). Conclusion. Opioid use within 24 hours of WCE did not significantly affect completion rates for inpatients or outpatients. GTT was prolonged in inpatients receiving opioids but not in outpatients.
