Abstract

Background and Study Aims. Patients undergoing therapeutic endoscopic retrograde cholangiography (ERC) may require different amounts of sedative agents depending on demographic characteristics, indication of ERC, and/or endoscopic intervention. Patients and Methods. We retrospectively analyzed all patients undergoing therapeutic ERC from 2008 - 2014 who received deep sedation with propofol ± midazolam. Results. A total of 2448 ERC procedures were performed in 781 patients. The cumulative per procedure propofol dose in the different groups was as follows: PSC 479 mg (±256), bile duct stones 356 mg (±187), benign stenosis/cholestasis 395 mg (±228), malignant stenosis 401 mg (±283), and postliver transplant complications 391 mg (±223) (p < 0.05). Multivariable analysis showed that dilatation therapy (p = 0.001), age (p = 0.001), duration of the intervention (p = 0.001), BMI (p = 0.001), gender (p = 0.001), platelet count (p = 0.003), and bilirubin (p = 0.043) influence independently the propofol consumption. Conclusions. Demographic characteristics and endoscopic interventions have a distinct influence on the amount of sedation required for therapeutic ERC. Although the sedation-associated complication rate is low optimization of sedative regimens is a prime goal to further reduce adverse events of therapeutic ERC.
