AIM:To determine the perigastric lymph node involvementin periampullar tumors,in an attempt to optimize the surgicaltreatment of pylorus-preserving pancreatoduodenectomy.METHODS:We retrospectively investigated the frequenceof lymph nodes involvement in pedgastric regions.Distributionand number of involved lymph nodes were exambined from112 patients with carcinoma of pancreas,59 patients withdistal bile duct carcinoma,and 41 patients with carcinomaof the papilla of Vater.RESULTS:The frequency of lymphatic spread of carcinomain pancreas;distal bile duct and papilla of Vater was 18.7%,1.9%,2.5% respectively.With regard to the mode oflymphatic spread in perigastric region,Infrapyloric nodes ofcarcinoma of the head of pancreas predominated over others,in carcinomas of the distal bile duct and the papilla of Vater,the left gastric artery,and the greater curvature lymph nodeswas the only sole sites,respectively.CONCLUSION:Understanding perigastric lymphaticinvolvement in periampullary tumors may be helpful for choosingthe appropriate surgical approaches to pancreatoduodenectomywith preservation of pylorus.
