Pancreatoduodenectomy with vascular reconstruction in treating carcinoma of the pancreatic head.
BACKGROUND
The incidence of carcinoma of the pancreas is increasing in the world. Pancreatic carcinoma is characterized by early local extension to contiguous structures and metastases to regional lymph nodes and the liver. This study was conducted to increase the rate of pancreatoduodenectomy combined with vascular reconstruction.


METHODS
Pancreatoduodenectomy with vascular reconstruction was performed for 79 patients at a number of hospitals in Fujian Province, Zhejiang Province, Shanghai and Xinjiang Uyghur Autonomous Region from April 1994 to December 2003. One of these patients also underwent right hemicolectomy; but all received through superior mesenteric vein (SMV)-portal vein (PV) reconstruction. The reconstructions of the superior mesenteric artery (SMA) and hepatic artery (HA) were performed in 4 patients, and reconstructions of the SMA or HA were carried out in 7 and 4 patients respectively. Partial reconstruction of the inferior vena cava (ICV) was done in 2 patients when the tumor was adhering to the wall of the inferior caval vein.


RESULTS
Four patients died during the peri-operative period, with a mortality rate of 5%. No complications such as biliary or pancreatic fistulae or artificial blood vessel infection were noted. Histological examination showed one patient with neuroendocrine cancer and the other 78 patients with adenocarcinoma of the pancreatic head. Resected endothelia and vascular margins proved to be microscopically tumor-free. Follow-up for 3 months to 10 years for all except two patients showed 7 of the 9 patients who had undergone resection and reconstruction of the SMA and HA died 7 months or 4 years after operation and 37 survived for over 3 years and 12 for more than 5 years. The rest are still under follow-up.


CONCLUSIONS
Pancreatoduodenectomy with vascular reconstruction for carefully selected patients with carcinoma of the pancreatic head has proved to be a safe and reliable treatment, capable of raising the rates of tumor resection and survival.
