چکیده

Aims: To evaluate the safety, effectiveness, success rate and complications of needle knife precut papillotomy for inaccessible bile duct after failed pancreatic ducts access. Methods: Selective common bile duct cannulation was required for 582 patients from November 2004 to May 2008. Precut sphincterotomy was performed in 28 patients (16 male, 12 female; mean age 71). When standard bile duct cannulation was unsuccessful after more than 20 minutes, the bile duct was considered inaccessible. Group A consisted of patients where pancreatic duct access was possible and transpancreatic papillary septotomy was performed (20 patients). If pancreatic duct cannulation also failed, needle knife precut method was performed and these patients belonged to group B (8 patients). The success and complication rates of the two groups were compared using the Chi-square test. Results: The success rates were 85% and 87.5% respectively. Of the 28 patients in group A, 6 had mild to moderate pancreatitis and one patient had mild bleeding. The complication rates were 35% and 0% respectively and the differences were not signifi cant. Conclusion: Needle knife precut papillotomy is useful and acceptable in patients after failed pancreatic duct access.

Endoscopic Papillary Large Balloon Dilation Combined with Guidewire-Assisted Precut Papillotomy for the Treatment of Choledocholithiasis in Patients with Billroth II Gastrectomy

BACKGROUND/AIMS Endoscopic extraction of bile duct stones is difficult and often complicated in patients with a Billroth II gastrectomy. We evaluated a simpler technique to achieve an adequate ampullary opening for the removal of choledocholithiasis using endoscopic papillary large balloon dilation (EPLBD) combined with a guidewire-assisted needle-knife papillotomy. METHODS Sixteen patients w...

A case of obstructive jaundice caused by impaction of a pancreatic stone in the papilla for which a needle knife precut papillotomy was effective.

CONTEXT Obstructive jaundice in chronic pancreatitis is generally caused by stenosis of the bile duct in the pancreas. Obstructive jaundice caused by the impaction of a pancreatic stone in the papilla is markedly rare, with only seven cases reported to date. CASE REPORT We report a case of obstructive jaundice caused by the impaction of a pancreatic stone in the papilla. A 41-year-old male wi...

Combined precut in difficult biliary cannulation.

AIM precut sphincterotomy refers to a variety of endoscopic techniques that are used in order to access the bile duct when conventional methods of cannulation have failed. There are not significant data (such as efficacy, safety) about the use of different techniques of precutting at the same session. We have described our experience with combined precut sphincterotomy (CPS) and we have compare...

Transpancreatic Precut Sphincterotomy for Biliary Access: The Relation of Sphincterotomy Size to Immediate Success Rate of Biliary Cannulation

Background. Transpancreatic precut sphincterotomy (TPS) is an option for difficult common bile duct (CBD) access, and the reports are few, with immediate success rate varying from 60 to 96%. The description of relation between the size of TPS and the immediate success rate of CBD cannulation was not found in the literature. The Aim of the Study. To evaluate the relation of large TPS to immediat...

Burdick's Technique for Biliary Access Revisited

The precut sphincterotomy is used to facilitate selective biliary access in cases of difficult biliary cannulation. Needle-knife precut papillotomy is the standard of care but is associated with a high rate of complications such as pancreatitis, duodenal perforation, bleeding, etc. Sometimes during bowing of the sphincterotome/cannula and the use of guide wire to facilitate biliary cannulation,...
