BackgroundThe development of endoscopic techniques such as endoscopic retrograde cholangiopancreatography (ERCP), endoscopic sphincterotomy (EST) and stenting are relatively new alternatives to surgery for the treatment of benign lesions in the biliary duct and pancreas. The objective of this study was to assess the value of stenting in the endoscopic pancreatic duct and biliary duct in the treatment of chronic pancreatitis with distal benign biliary stricture.MethodsTwenty-two patients diagnosed with chronic pancreatitis with distal benign biliary stricture underwent endoscopic treatment in our center, with ERCP, EST, endoscopic retrograde biliary drainage (ERBD) and endoscopic retrograde pancreatic drainage (ERPD) with stents. A numeric rating scale was used to assess pain intensity. The clinical data on endoscopic therapies and recovery of the patients were recorded and compared.ResultsERCPs were successfully performed in 21 patients and 1 (4.5%) failed because of pancreatic ductal variation. A total of 68 ERCPs were performed with 47 pancreatic duct stents and 39 biliary duct stents. The rate of complications was 13.2% (9/68). The abdominal pain score after endoscopic treatment was significantly reduced. The levels of bilirubin and alanine transaminase in all 21 patients were improved compared to those before endoscopic treatment.ConclusionEndoscopic stent drainage of the pancreatic duct and biliary duct for chronic pancreatitis with distal biliary benign stricture can be selected as a safe, effective and minimally invasive therapeutic method.
