DIAGNOSIS AND TREATMENT OF NEOPLASTIC DIS EASES OF EXTRAHEPATIC BILE-DUCTS AND MAJOR DUODENAL PAPILLA

Fifty-three operations were conducted on 48 patients for tumors of the extrahepatic bile ducts and the major duodenal papilla. Early diagnos is of this pathological condition is very difficult, which affects dir ectly the results of treatment; 18 % of patients underwent radical ope rations. Modern diagnostic methods-computered tomography, ultrasonic e xamination, and endoscopic retrograde pancreatocholangiography made it possible to detect neoplastic diseases in all of the examined patient s. Radical surgical treatment is expedient in distal localization of t he neoplastic process and in the absence of metastases. Endoscopic and puncture methods of decompression of the bile ducts are andicated in diffuse forms of the disease.
