All the patients underwent individualized management including endoscopic therapy and were followed

up post operatively about clinical symptoms. Results: Five of these 11 patients diagnosed as portal cavernoma presented with abdominal pain and jaundice, the examination showed biliary strictures and bile duct stones, they underwent initial endoscopic biliary sphincterotomy, then biliary decompression (plastic stent = KU-60019 mouse 3, recyclable coated metal stent = 1, nasal biliary drainage = 1), 4 patients were followed up for 6 m ∼ 24 m with no relapse. Two of these 11 patients presented with gastrointestinal hemorrhage after choledochojejunostomy, the examination showed biliary-enteric anastomotic stoma varices with bleeding, porto-systemic shunting were performed (transjugular intrahepatic portosystemic shunt Idelalisib datasheet = one, surgery = one), the two patients had been relieved without recurrence over the follow-up period (2 years and 6 months). The remaining four patients experienced cholangitis symptoms, were diagnosed as calculus of common bile duct, they all suffered from endoscopic biliary sphincterotomy and balloon stone

extraction, a follow-up period of average 11 months showed no relapse. Conclusion: Approximately 20% of patients with PHB are with symptoms of biliary system, and these patients need individualized treament. Endoscopic management including sphincterectomy, stone extraction and /or stent insertion is safe, minimal invasive and effective therapy. Porto-systemic shunting should be considered in the case of persistent biliary obstruction and/or hemorrhage because of portal hypertension.

affiliated hospital of Nanchang university Objective: Endoscopic retrograde cholangiopancreatography (ERCP) is widely used in diagnosis and treatment of hepatic, biliary and pancreatic diseases. As a trauma examination means, post- ERCP has a variety of complications. Among of them, post-ERCP pancreatitis and cholangitis are the most two of common complications, may result in prolonged hospitalization, Immune system and further intervention. It is very important to search for an effective prevention method for the patients. Our study aimed to determine the application and effect of antibiotics in preventing post-ERCP pancreatitis and cholangitis. Methods: A retrospective study was available. From January 1, 2012 to December 31, 2012,All of the patients who underwent ERCP in endosocopy center of the first affiliated hospital of Nanchang university were analyzed that the interference factors such as age, sex and based diseases have no statistical difference compared with control group. A total of 1231 people, were divided into 3 group by randomized: the first group and second group are the experimental group, the third group as control.
