ABSTRACT
Background and purpose:Radical surgery remains the main treatment for the patients with pancreatic and duodenal cancer,but resectability rate is low when clinically diagnosed,portal vein/superior mesenteric vein or inferior caval vein invaded by tumors are a few of the main reasons.How to increase resectability of pancreatic cancer and duodenal cancer still is very challenging to the clinician.This study was done to explore the feasibility of the new surgical approach for the treatment of pancreatic and duodenal cancer with portal vein/superior mesenteric vein or inferior caval vein invasion.Methods:5 patients received pancreatoduodenectomy with vascular reconstruction between February 2002 and June 2005.Three patients with pancreatic head cancer underwent pancreatoduodenectomy combined with portal vein/SMV resection and vascular reconstruction and two patients with duodenal cancer underwent pancreatoduodenectomy combined with inferior caval vein resection and vascular reconstruction.Results:There was no surgery related death.The serious complications such as artificial blood vessel infections or obstructions were not experienced.After surgery,one patient died 10 months later,one patient died 24 months later,two patients survived for over 3 years and one patient over 4 years.Conclusions:Pancreatoduodenectomy with vascular reconstruction for patients with carcinoma of the pancreatic head or duodenum invading portal vein/superior mesenteric vein or inferior caval vein has been proved to be a safe treatment,it could improve the resectability of the tumor and prolong survival.
ABSTRACT
Background and purpose:In all treatments of retroperitoneal tumors,surgical operation is still the only effective method which might cure the tumors.However,the patients were always in advanced stages when they were clinically diagnosed.The inferior cava of the patients always have been invaded by tumors,which is considered to be a relative surgical contraindication.This study was to explore the surgical method in treatment of retroperitoneal tumors with major blood vessels invasion,and in order to raise the resection rate and survival rate. Methods :Retrospective analysis of twelve cases which implicate major vessels and have parallel artificial vascular reconstruction during operations of retroperitoneal tumor from January 2003 to June 2007. Results :Twelve cases of retroperitoneal tumor and implicated major vessels were integrally resected,corresponding important vascular reconstructions were done,no short-term postoperative deaths. Conclusions :Retroperitoneal tumor involving abdominal important vessels is not a contraindication of radical surgical.Integrated resection of retroperitoneal tumor and implicated major vessels and corresponding important vascular reconstruction are safe,and can improve the resection rate and reduce the relapse rate,extend the survival time.
