[Hepatobiliscintigraphy in the diagnosis of obstructive jaundice].

The authors show the role of hepatobiliscintigraphy (HBSG) in cholelithiasis as a screening technique in evaluating the patency of the common bile duct, which allows cholecystectomy to be performed if there are normal values, without resorting to additional studies. They have reprospectively analyzed the results of clinical and instrumental studies in 101 patients with cholelithiasis and obstructive jaundice of various etiology in whom the diagnosis was verified by endoscopic cholangiopancreatography (ERCPG). The sensitivity, specificity, and diagnostic efficiency of the scintigraphic technique were 96.5, 36.3, and 86.1%, respectively. It is recommended that invasive diagnostic techniques, such as ERCPG and other direst X-ray contrasting methods, should be used after having a positive result of two techniques: ultrasonography and HBSG (in the above order).
