Core Tip

Core tip: Accurate examination of dissected lymph nodes is important for precise staging in gastric cancer treatment. We investigated the usefulness of the fat-dissociation method for lymph node harvest in gastric cancer. We used the fat-dissociation method on 24 resected specimens from patients with gastric cancer who underwent standard curative gastrectomy and lymph node dissection at our hospital, while the conventional method was used on 32 specimens. There were no differences in the numbers of harvested lymph nodes between these two groups; however, there was a 60 min reduction in the total median duration of the procedure when using the fat-dissociation method.
