Safety of same-day endoscopic ultrasound and endoscopic retrograde cholangiopancreatography under conscious sedation

AIM: To assess the tolerability and safety of same-day tandem procedures, endoscopic ultrasound (EUS) followed by endoscopic retrograde cholangiopancreatography (ERCP) under conscious sedation. METHODS: A retrospective review was conducted at Loma Linda University Medical Center, a tertiary-care center. All 54 patients who underwent EUS followed by ERCP (group A) from 2004 to 2006 were included in the study. A second group of 56 patients who underwent EUS only (group B), and a third group of 53 patients who underwent ERCP only (group C) during the same time period were selected consecutively as control groups for comparison. RESULTS: Conscious sedation was used in 96% of patients in group A. Mean dosages of meperidine and midazolam used in group A were significantly higher than in group B or C. Mean recovery time in group A was not statistically longer than in group B or C. There was no significant difference in the incidence of sedation- related and procedural-related complications. CONCLUSION: Tandem EUS/ERCP procedure can be safely performed under conscious sedation with minimal adverse events. Combined procedures, however, are associated with higher dosages of sedatives, and slightly longer recovery time. © 2010 Baishideng.
