[Changes in lymph node dissection for pancreatic cancer].
Two step pancreatoduodenectomy for periampullary carcinoma was first reported in 1912 by Kausch. Pancreatoduodenectomy performed for carcinoma of the head of the pancreas was first reported in 1937 by Brunschwig. Before this report, all previous pancreatoduodenectomy had been performed for other periampullary tumors. By the 1960's, pancreatoduodenectomy was performed for pancreatic cancer without lymph node dissection. However, Fortner advocated regional pancreatectomy for pancreatic cancer in 1973. In our institute, also, extended radical pancreatectomy by translateral retroperitoneal approach has been performed during the past 2 decades. Many Japanese surgeons also adopted extend pancreatectomy. In the 1980's, extended radical pancreatectomy consisted of paraaortic lymph node dissection, total pancreatectomy, and complete resection of extrapancreatic nerve plexus. However, based on the many clinicopathologic studies, pancreatoduodenectomy was better operative procedure than total pancreatectomy. Although extended radical pancreatectomy has the advantage of long-time survival, disadvantage of nutritional status and quality of life was produced by this operative procedure. Tarverso and Longmire reported new operative procedure of pylorus preserving pancreatoduodenectomy (PPPD) in 1978. Recently, this operative procedure was indicated for pancreatic cancer. However, there is a question whether PPPD is the best operative procedure for pancreatic cancer or not.
