Objective To evaluate the clinical results from different endoscopic treatments of patients with chronic pancreatitis. Methods Thirty-seven cases of chronic pancreatitis had accepted endoscop-ie treatments were analvzed retrospectively. Results All cases were diagnosed clearly by ERCP showing different degree of pancreatic duct dilatation. Among them 21 cases had pancreatic duct stricture, 9 cases pancreatie duet ealeification. EPS in 18 cases and EST in 37 cases, basket extraction pancreatic duct stones in 6 eases, PDSD in 17 cases, NPD in 5 cases were conducted. The abdominal pain in 34 cases disappeared or markedly relieved alter treatment. Conclusion Endoseopie treatments have the advantages of safe, less-trauma and effectiveness. The combination of different endoscopic treatments improved evidently the current state of chronic pancreatitis treatment, thereby the therapeutic results.

Objective To evaluate the diagnostic and therapeutic effects of endoscopic retrograde cholangiopancreatography (ERCP) in biliary papillomatosis. Methods Data of 6 patients, who underwent ERCP and diagnosed as biliary papillomatosis from 2000 to 2008, were retrospectively analyzed. Results There were 3 males and 3 females, with the mean age of onset at 72.8 years (range 52-83 years). Recurrent cholangitis and jaundice were common presentations in all patients, with 5 patients having right upper abdominal pain and 3 others exhiting fever and algor. History of partial hepatectomy was observed in 2 patients. Endoscopic findings included dilated papillary orifice with mucin discharge in 5 patients and papillary-occupying lesion in 1 patient. Multiple filling defects in the lumen of the biliary system in dilated common bile duct were detected in all patients, accompanied with extra-hepatic ducts dilatation in 3, right intra-hepatic duct dilatation in 1, and major pancreatic duct dilation in 1. Of 6 patients, 5 underwent multiple ERCP, inclucling stents and endoscopic nasobiliary drainage (ENBD), and have survived for 10-30 months. Another 83-year-old patient underwent palliative endoscopic treatment with balloons, baskets and ENBD, but died of cholangitis 10 days after the procedure. Conclusion This case series reports the typical endoscopic findings of biliary papiliomatosis. For inoperable or postoperative recurrent patients, endoscopic palliative treatment is a safe, convenient and effective procedure.

Objective To explore the experience on using duodenoscope to treat hepatolithiasis through normal physiological ways.Methods ERCP,EST were used firstly,then removed calculus of the extrahepatic bile duct.Endoscopic papillary balloon dilatation was used if there was stenosis of bile duct.Removed calculus when it had been crushed in the hepatic duct.Injected decoction to dissolve calculus through endoscopic nasobiliary drainage,or inserted the endoscopic retrograde biliary drainage when the calculus was hard to removded.Results 101 cases of calculus in the extrahepatic bile duct were all removed.215 cases of hepatolithiasis were cleaned out at first time.9 cases were cured 1 week after dissolving calculus through endoscopic nasobiliary drainage.59 cases carried out ERBD,and 21 of them were cured 3 months later,37 patients were still in regular follow-up.33 cases with stenosis of bile duct were treated by endoscopic papillary balloon dilatation,19 of them were cured,the others were inserted with the endoscopic retrograde biliary drainage.19 cases of cholangitic abscess were cured by endoscopic nasobiliary drainage.Conclusion Using duodenoscope to treat hepatolithiasis through normal physiological ways is safe and effectic.

Objective To explore the experience of the double guide wires technology in the difficult ERCP examinations.Methods There were 776 difficult ERCP patients.701 cases with difficult cannulation of the bile duct had been inserted another guide wire into the upper left corner of the duodenal papilla after retained pancreatic guide wire.75 cases with difficult cannulation of the pancreatic duct had been inserted another guide wire into the right vertical direction of the duodenal papilla after retained a guide wire into the commom bile.Results 697cases(99.4%)with difficult cannulation of the bile duct were examined successfully at first time;74 cases(98.7%)with difficult cannulation of the pancreatic duct were examined successfully at first time.Conclusion Double guide wires technology is easy to use.The method of retaining a guide wire into the duct which was cannulated easily may increases the achievement ratio of cannulation into another duct.The check time was shortened significantly.
