| 抄録 | OBJECTIVES: Identifying a bile duct (BD) stone in patients with acute biliary pancreatitis (ABP) is important for the management and prevention of recurrent attack of pancreatitis. The aim of this study was to prospectively evaluate the usefulness of intraductal ultrasonography (IDUS) in patients suspected to have ABP but with no evidence of choledocholithiasis on ERCP.METHODS: Total 92 patients suspected with ABP without evidence of BD stones on imaging studies including ERCP were enrolled. Stones or sludge detected by IDUS were confirmed after endoscopic sphincterotomy (EST) and extraction. If IDUS finding was negative, we swept the BD with a balloon catheter and/or basket without EST.RESULTS: IDUS revealed BD stones in 33 (35.8%). These BD stones were all confirmed endoscopically. IDUS showed biliary sludge in 26 (28.2%) patients, and 22 patients' sludge were confirmed by endoscopic visualization after EST. During the mean follow-up of 24 months, pancreatitis did not recurred in 90 of 92 patients (97.9%) with ABP.CONCLUSIONS: IDUS improves diagnostic accuracy for the detection of clinically occult BD stones in patients suspicious ABP. IDUS guided endoscopic management for patients with ABP can avoid unnecessary EST and help prevent recurrent pancreatitis. |
