title: [Stomach neoplasms in the IX Region of Chile: comparison of the anatomo-pathological study of lymph node emptying in 2 periods].
abstract: Complete resection of lymph nodes may help achieve a cure in patients with gastric cancer. In this paper we evaluate the yield of a careful search for lymph nodes in fresh tissue obtained immediately after resection. A mean of 42.5 nodes per gastric piece was obtained, which is significantly higher than that previously reported with examination of fixed tissue. The yield was higher for all node groups except the left para-cardial one.
