[Endoscopic duodenobiliary drainage in the treatment of mechanical jaundice of blastomatous etiology].

The experience of endoscopical treatment of 112 patients with blastomatous disease of extrahepatic biliary ducts was summarized. Principal method of biliary bypass was duodenobiliary drainage with the use of transpapillary endoprostheses. Endoprosthetic procedure was carried out in 79 (70.5%) patients, which gave the possibility in 14 of them after elimination of jaundice and cholangitis to perform radical operations. In 52 cases duodenobiliary drainage was used as the final palliative procedure. In 13 patients due to insufficient effect of prosthesis biliary draining procedures were used. The causes of failures in 33 (29.5%) cases were infiltrative growth of the tumor into bowel wall with stricture formation as well as high and extended lesion of hepaticocholedochus duct.
