| Research Abstract |
This study was designed to reevaluate the pathological spread of resected specimens for pancreato-biliary cancer, develop the operative procedures of resection and reconstruction of the main vessels in the pancreato-biliary system, and elucidate the adequate range of lymphatic dissection according to the extension of the tumor. Some institutes which have ever operated many cases of the same carcinoma, or specialized in the blood vessel surgery joined it. It became clear that the previous procedures might be unable to remove curatively the advanced cancer of the pancreato-biliary system from the pathological investigation of the extension of cancers, and curative removements needed a combined resection of the total hepato-duodenal ligament for biliary cancer and a combined resection of the superior mesenteric vein and artery. In the combined resection of the blood vessels, a combined resection of the portal vein became safer and more certain, but the technique of a combined resection of arteries such as the hepatic artery and the superior mesenteric artery still remained insufficient. However, this study showed that the combined resection of these arteries would be resolved in the near future by the continuous research about these problems.
