Abstract
- We analyzed findings of sonography and ERCP retrospectively to compare the diagnostic accuracy of sonographywith ERCP in patients suspected with biliary stones. 88 patients underwent surgery who had studied with sonographyand ERCP were evaluated in order of intrahepatic duct, extrahapatic duct and gall bladder. Of these patients, 80cases were proved billiary stones. Sonography correctly diagnosed 19 of 19 patients with intrahepatic duct stones,32 of 40 patients with extrahepatic duct stones and 35 of 41 patients with gall stones with sensitivities of 100%, 80% and 85% rspeictively. ERCP correctly identified 14 of 18 patients with intrahepatic duct stones, 26 of 37patients with extrahepatic duct stones and 15 fo 33 patients with gall stones with sensitivities of 78%, 70% and45% respectively. Our results shows sonography is more sensitive to detect stones of biliary system than ERCP.
