抄録

The results of microsurgery carried out during associated arterial resection with reconstruction in cases of progressive pancreatic and biliary tract cancer accompanyning by infiltration into the hepatic or superior mesenteric artery were investigated. The significance and problem in performing this procedure are briefly discussed.<br> Of 10 patients subjected to this study, 6 patients had pancreatic carcinoma and 4, biliary tract cancer. Portal vein resection was performed in 6 cases. In 7 cases, in which postoperative blood circulation of the reconstructed artery was checked by arteriography, excellent patency was confirmed. Six patients had postoperative complications and 4 of the 6 died postoperatively resulting from complications accompanied with reconstruction of the hepatic artery. The longest postoperative survival period was 11 months in patients with pancresatic carcinoma and 14 months in cholangiocarcinoma.<br> Microsurgery-applying associated arterial resection with reconstruction improved the rate of postoperative patency of arteries, however, it could not contribute to improve the surgical outcome in patients with pancreatic or extrahepatic biliary tract carcinoma.
