          Abstract

          Endoscopic retrograde cholangiopancreatography (ERCP) is associated with a spectrum of complications such as pancreatitis, hemorrhage, perforation, and cardiopulmonary events. These complications can range from mild to severe resulting in extended hospitalization, requiring surgical intervention, and leading to permanent disability or even death. Complications of ERCP have been better understood in the past decade, with adoption of standardized consensus-based definitions of complications and introduction of new recommendations to minimize risks of ERCP. Adequate selection of patients undergoing ERCP, skilled operators using novel techniques and prompt identification and treatment are key to successful prevention and management.

          Complications of endoscopic biliary sphincterotomy.

          Endoscopic sphincterotomy is commonly used to remove bile-duct stones and to treat other problems. We prospectively investigated risk factors for complications of this procedure and their outcomes. We studied complications that occurred within 30 days of endoscopic biliary sphincterotomy in consecutive patients treated at 17 institutions in the United States and Canada from 1992 through 1994. Of 2347 patients, 229 (9.8 percent) had a complication, including pancreatitis in 127 (5.4 percent) and hemorrhage in 48 (2.0 Percent). There were 55 deaths from all causes within 30 days; death was directly or indirectly related to the procedure in 10 cases. Of five significant risk factors for complications identified in a multivariate analysis, two were characteristics of the patients (suspected dysfunction of the sphincter of Oddi as an indication for the procedure and the presence of cirrhosis) and three were related to the endoscopic technique (difficulty in cannulating the bile duct achievement of access to the bile duct by "precut" sphincterotomy, and use of a combined percutaneous-endoscopic procedure). The overall risk of complications was not related to the patient's age, the number of coexisting illnesses, or the diameter of the bile duct. The rate of complications was highest when the indication for the procedure was suspected dysfunction of the sphincter of Oddi (21.7 percent) and lowest when the indication was removal of bile-duct stones within 30 days of laparoscopic cholecystectomy (4.9 percent). As compared with those who performed fewer procedures, endoscopists who performed more than one sphincterotomy per week had lower rates of all complications (8.4 percent vs. 11.1 percent, P=0.03) and severe complications (0.9 percent vs. 2.3 percent, P=0.01). The rate of complications after endoscopic biliary sphincterotomy can vary widely in different circumstances and is primarily related to the indication for the procedure and to endoscopic technique, rather than to the age or general medical condition of the patients.

            Incidence rates of post-ERCP complications: a systematic survey of prospective studies.

            To provide health-care providers, patients, and physicians with an exhaustive assessment of prospective studies on rates of complications and fatalities associated with endoscopic retrograde cholangiopancreatography (ERCP). We searched MEDLINE (1977-2006) for prospective surveys on adult patients undergoing ERCP. "Grey literature" was sought by looking at cited references to identify further relevant studies. Data on postprocedural pancreatitis, bleeding, infections, perforations, and miscellaneous events as well as their associated fatalities were extracted independently by two reviewers. Sensitivity analysis was performed to test for data consistency between multicenter versus single center studies, and old (1977-1996) versus recent (1997-2005) reports. In 21 selected surveys, involving 16,855 patients, ERCP-attributable complications totaled 1,154 (6.85%, CI 6.46-7.24%), with 55 fatalities (0.33%, CI 0.24-0.42%). Mild-to-moderate events occurred in 872 patients (5.17%, CI 4.83-5.51%), and severe events in 282 (1.67%, CI 1.47-1.87%). Pancreatitis occurred in 585 subjects (3.47%, CI 3.19-3.75%), infections in 242 (1.44%, CI 1.26-1.62%), bleeding in 226 (1.34%, CI 1.16-1.52%), and perforations in 101 (0.60%, CI 0.48-0.72%). Cardiovascular and/or analgesia-related complications amounted to 173 (1.33%, CI 1.13-1.53%), with 9 fatalities (0.07%, CI 0.02-0.12%). As compared with old reports, morbidity rates increased significantly in most recent studies: 6.27%versus 7.51% (P(c)= 0.029). ERCP remains the endoscopic procedure that carries a high risk for morbidity and mortality. Complications continue to occur at a relatively consistent rate. The majority of events are of mild-to-moderate severity.

              Endoscopic sphincterotomy complications and their management: an attempt at consensus.

              Despite its relative safety (in comparison with surgery), and undoubted role in many clinical circumstances, biliary sphincterotomy is the most dangerous procedure routinely performed by endoscopists. Complications occur in about 10% of patients; 2 to 3% have a prolonged hospital stay, with a risk of dying. This document is an attempt to provide guidelines for prevention and management of complications, based on a workshop of selected experts, and a comprehensive review of the literature. We emphasize particularly the importance of specialist training, disinfection, drainage, and collaboration with surgical colleagues.
