Extended resections of ductal pancreatic cancer--impact on operative risk and prognosis.

114 patients received a standard and 75 patients an extended resection of ductal pancreatic carcinoma at the Hanover Medical School, Germany, from 1971 until 1993. Standard pancreatic resections were combined with vascular resection and reconstruction in 46 and additional organ resections in 45 cases. Vascular resections affected the mesentericoportal vein in 37, the common hepatic in 10 and the superior mesenteric artery in 7 cases. Pancreas resections were combined with total gastrectomy in 23, partial colectomy in 17, hemihepatectomy in 14, adrenalectomy in 8 and nephrectomy in 5 patients. Curative resections could be accomplished in 86% of patients without and 81% with extended resections. Additional vascular resections neither increased the operative risk nor deteriorated the long-term prognosis after resection. Additional organ resections, however, significantly increased the risk of lethality and impaired the long-term prognosis. Especially resections of synchronous hepatic metastases and colectomies were associated with a poor survival probability.
