This study was to compare the accuracy of IDUS and endo- scopic retrograde cholangiography (ERC) in the diagnosis of extrahepatic bile duct stones. METHODS: Thirty patients suspected of extrahepatic bile duct stones on B ultrasonography, CT, or MRI were en- rolled for study. ERC was performed using a Fujinon duo- denoscope (ED-410XT, ED-410Xu), then IDUS was done by inserting a Fujinon microprobe (PL2220-15) through the endoscopic biopsy channel to detect the extrahepatic bile duct. Finally stones in the extrahepatic bile duct were detected and extracted by endoscopic sphincterotomy (EST). RESULTS: Among the 30 patients, 26 were diagnosed as having cholelithiasis accurately through ERC. In one pa- tient the stone detected by ERC was really floccule. Mis- diagnosis happened in 2 patients with extrahepatic bile duct stones. So the overall accuracy and sensitivity of ERC in the diagnosis of extrahepatic bile duct stones were 86.7% (26/30) and 92.9% (26/28) respectively. In contrast, IDUS showed the results of diagnosis were in consistent with those of EST stone extraction. Its accuracy and sensi- tivity in the diagnosis of extrahepatic bile duct stones were 100% (30/30) and 100% (28/28) respectively. CONCLUSION: IDUS which is superior to ERC in diagno- sing extrahepatic bile duct stones can avoid the visual error of ERC.展开更多
