[Clinicopathological Examination of 81 Cases Added Gastrectomy for Early Gastric Cancer after ESD].

As a general rule, our department has performed additional gastrectomy with lymph node dissection(radical surgery: RS) for non-curative endoscopic submucosal dissection(ESD)cases. This time, we performed a clinicopathological study on 81 patients who underwent RS after ESD for 10 years from May 2009 to April 2019. Lymph node metastasis(LNM)was observed in 5 cases and local cancer residue(LCR)was observed in 8 cases. Examination of the presence or absence of LNM and LCR by clinicopathological factors(histopathological type, tumor size, lymphatic invasion[ly], venous invasion[v], horizontal margin[HM], vertical margin[VM], submucosal invasion, ulceration[scar])revealed no significant risk factor for LNM, however, tumor size and HM were significant risk factors for LCR. The relationship between the eCura system and the case rate associated with LNM in our hospital was similar to that in the original report. Regarding the prognosis, there was one local recurrence and no death from the primary disease.
