Balanced Propofol Sedation Versus Propofol Alone Sedation in Therapeutic Endoscopic Retrograde Cholangiopancreatography (ERCP)

Based on previous results, the investigators considered that sedation quality, complications, and procedure outcomes may not be different, however, propofol alone titration may have a fast recovery time than BPS and cost-effectiveness than balanced propofol sedation (BPS). In present study, the investigators therefore evaluate the time and sedation quality of patient recovery, cost-effectiveness, complication, and procedure outcomes between propofol alone and BPS in therapeutic endoscopic retrograde cholangiopancreatography (ERCP).
