Abstract

Ultrasound is the modality of choice for the diagnosis of cholelithiasis and for the evaluation of theintra-and extra hepatic biliary tree in the patient with jaundice, but its role in the diagnosis ofcholedocholithiasis is less certain. We retrospectively examined 127 patients who had undergone ERCP by performingright upper quadrant sonography immediately prior to ERCP and undergone surgery due to biliary stone. We assessedthe size of the intra-and extrahepatic ducts and presence or absence of calculi, and compared the detection rateof ultrasound with that of ERCP in the patient with biliary stone in order of gall bladder, extrahepatic duct, andintrahepatic duct. the results are as follows: 1. Of all 127 patients with biliary stone, female were 75(59%). 6thdecades were most common. 2. Each numbers of patients in the order of biliary location are 43 in gall bladder, 17in intrahepatic ducts, 23 in extrahepatic ducts, 44 in multiple locations. 3. Gall bladder stones were 81 in totaland ultrasound detected stones in 75 patients (sensitivity;93%). ERCP-in 35 patients(Sensitivity;43%) 4.Extrahepatic duct stones were 54 in total and ultrasound detected stones in 31 patients (Sensitivity;91%) 5.Intrahepatic duct stones were 45 in total and ultrasound detected stones in 38 patients(Sensitivity;84%). ERCP-in41 patients(Sensitivity;91%) In summmary, Ultrasound is much more sensitive to detect GB stones thanERCP(93%;43%). ERCP is much more sensitive to detect extrahepatic duct stones than ultrasound (91%;57%).Sensitivity of ultrasound and ERCP were almost equal in the intrahepatic duct stones(84%;91%)
