ABSTRACT

Objective To evaluate the efficacy and safety of emergency endoscopic needle-knife sphincterotomy in acute biliary pancreatitis caused by impacted common bile duct stones at duodenal papilla.Methods Between Jan 2007 and Jan 2017,115 cases underwent emergency endoscopic retrograde cholangiopancreatography (ERCP) and needle-knife sphincterotomy.Clinical data were recorded and analyzed.Results Procedures were successful in all cases.The mean operative time of needle-knife sphincterotomy was (22.5 ± 13.7) min.The clearence of impacted stone at duodenal papilla was 87.8％(101/115).The syptoms of pancreatitis promptly relieved after emergency ERCP.Postoperative white blood cell count,serum amylase and liver function improved significantly.The complication rate was 5.2％ (6/115),including 3 cases of hemorrhage and 3 cases of acute cholangitis,which were cured by conservative treatment.There was not procedure-related mortality.Conclusions Emergency endoscopic needle-knife precut sphincterotomy is effective and safe for acute biliary pancreatitis caused by impacted common bile duct stones at the duodenal papilla.
