title: [Comparative characteristic of preoperative magnetic resonance and intraoperative cholangiography in diagnostics of the common biliary duct disorder].
abstract: The investigation objective have had constituted comparative characteristic of the magnet resonance cholangiography (MRCHG) and intraoperative cholangiography (IOCHG), which were applied in 186 patients, suffering biliary calculous disease. Basing on results of the performed standard operational investigations, three groups of the general biliary duct (GBD) risk affection were delineated: high, middle and low. In the high risk group were included 82 patients, in whom in GBD its widening and echopositive mass presence were revealed, as well as cholangitis, pancreatitis, obturation jaundice and raising of the cholestatic enzymes activity. The middle risk group was presented by 41 patients, in whom the ultrasound investigations data did not show the changes, but nonspecific raising of the hepatic enzymes activity was registered or they have had jaundice and pancreatitis in anamnesis. In the low risk groups were included 63 patients, in whom preoperative investigations did not show pathologic changes. The GBD affection was diagnosed in 82 patients. The investigation results have shown, that along with lowering of the GBD risk affection revealing, the MRCHG sensitivity lowers (in the groups--93.1, 80 and 57.1%, accordingly), and specificity is raising (90, 96.7 and 98.2%). Conduction of intraoperative cholangiography is indicated to all patients in high and middle risk of GBD affection, in low risk--in necessity. In a distal affection of GBD MRCHG owes low sensitivity and specificity.
