Pancreatic-duct stent placement facilitates difficult common bile duct cannulation.

BACKGROUND: Cannulation of the common bile duct can be difficult in certain instances. Difficult cannulation has been demonstrated to be a risk factor for post-ERCP pancreatitis. We report a technique to facilitate difficult cannulation that uses a pancreatic-duct stent to guide biliary cannulation. METHODS: A retrospective review of all ERCPs performed at our institution from October 1, 2000 to June 30, 2004 (1638) was performed to identify all cases in which a pancreatic-duct stent was placed to guide common bile duct cannulation. Charts on these patients then were reviewed to assess cannulation success and complications. In addition, indications for the ERCP and previously failed cannulation attempts by outside physicians were documented. OBSERVATIONS: Thirty-nine patients had pancreatic-duct stents placed as an aid to guide common bile duct cannulation. Successful cannulation of the bile duct was achieved in 38 of the 39 patients (97.4%) Procedure-related pancreatitis occurred in two patients and was mild in both. There were no procedure-related deaths. CONCLUSIONS: In cases of difficult common bile duct cannulation, placement of a pancreatic-duct stent as a guide to aid common bile duct cannulation appears to be an effective and safe technique.

Common bile duct diameters after endoscopic sphincterotomy in patients with common bile duct stones: ultrasonographic evaluation.

BACKGROUND: One of the most reliable, frequently used imaging techniques in cholestasis is ultrasonography (US) for the diagnosis of common bile duct (CBD) stones. METHODS: In this study, changes in diameters of CBD were determined ultrasonographically before and after endoscopic sphincterotomy (ES) in 46 patients with stone-induced dilated CBD. RESULTS: There was a significant decrease in CBD diameter measured 1 week after ES and extraction of stone (p < 0.001). In 87% of cases, the difference was more significantly pronounced during the first 24 h of ES. The mean CBD diameters on US were 13.70 +/- 3.00 mm (10-21 mm) before and 9.13 +/- 2.90 mm (4.2-18 mm) 24 h after endoscopic treatment (p < 0.001). After ES, six patients (13%) with inadequate decreases in CBD diameters were found to have residual stones. CONCLUSION: US can show residual stones in the CBD with the same efficacy as endoscopic retrograde cholangiopancreatography.

Congenital dilatation of the common bile duct in children.--The etiologic significance of the narrow segment distal to the dilated common bile duct.

Radiographic studies of 26 choledochal cyst patients were evaluated. Abnormal junction of the pancreatico-biliary system (PBS) was demonstrated in all patients. The transverse diameter of dilated common bile ducts was closely related to the length of the narrow segment of the distal common bile duct. Common bile ducts had not dilated despite the anomalous junction of PBS during the follow-up period, ranging from 2 to 12 years after choledochocysto -jejunostomy in 7 patients. The present studies indicate that no abnormal junction of PBS but stenosis of the distal common bile duct may be etiologically responsible for the choledochal cyst.
