Extended pancreaticoduodenectomy combined with resection of the involved portal vein(PV) and superior mesenteric vein(SMV)

Objective To explore the feasibility of the radical resection of cancer of head of pancreas with involving PV and SMV.Methods The data of 16 cases who underwent extended pancreaticoduodenectomy for tumors with involvement of PV/SMV were analysed retrospectively.The 16 cases all underwent extended pancreaticoduodenectomy.In 9 of the 16 cases partial resection of the wall of blood vessels was performed,5 cases mnderwent segmental resection of the blood vessel and end-end anastomosis,2 cases had segmental resection of the blood vessel and homologous vein transplantation.Results No cases of embolization,intestinal necrosis or hepatic failure were found in the whole group.One case died of mutiple organ failure was days after operation,and all the others were survival after operation and were followed up.Survival time was more than 3 years in 3 cases,and more than 5 years in 1 case,and 3~26 minths in 4 cases.Conclusions It is feasible to perform extended pancreaticoduodenectomy for cases of pancreatic head carcinoma with involvement of PV/SMV.
