For progressive pancreatic cancer with portal infiltration, it is thought that, if combined resection of the portal vein resulted in curability A or B, it is expected to be no significant difference in prognosis between the case used this method and the case of curability A or B without portal infiltration.
We carried out extended pancreatectomy combined with resection of the portal vein in 46 cases from October 1986 to December 1998. When evaluating these prognosis, average survival time for curability A and B was 12.3 months as compared with 5.0 months for curability C, the former one was significantly better in prognosis and one case of them had 6 years or more survival time. On the other hand, the later one had little significance of operation as compared with the national average of survival time being without operation.
If overestimation before operation was avoided and complete cure could be expected, aggressive resection alone can be used to improve prognosis of the pancreatic cancer with portal infiltration. However, it will result in little significance without complete cure. The collateral vessel may sometimes be found after cutting it during combined resection of the portal vein in particular, and it is an issue to ensure the portal blood stream after operation if changing the technique. We experienced a case that could avoid this problem by using stent in the portal vein. It is considered that curative operation is required to be performed safely and exactly using these techniques concurrently.
