[Ultrasonography in the diagnosis of cholelithiasis and its complications].

The author presents the results of ultrasound investigation (USI) of 419 patients with cholecystocholedocholithiasis. The diagnostic accuracy of USI methods in patients with calculous cholecystitis was 98.8%. Direct signs of visualization of concrements in the common bile duct (CBD) were found but in 68.5% of patients. On the basis of USI results the common bile stones were found in 287 (68.5%) patients. The concrements omitted in transabdominal USI were diagnosed using endoscopic retrograde cholangiopancreaticography, magnetic resonance cholangio-pancreaticography, endoscopic ultrasonography as well as in operative intervention.
