Endoscopic submucosal dissection versus surgery in elderly patients with early gastric cancer of relative indication for endoscopic resection

Surgery is recommended for early gastric cancer (EGC) beyond the endoscopic resection (ER)‐indication for the risk of lymph node metastasis; however, ER may be chosen as a “relative ER‐indication” considering age and comorbidities. This study aimed to compare outcomes of endoscopic submucosal dissection (ESD) only and surgery (primary surgery and additional surgery after non‐curative ESD) among elderly patients with relative ER‐indication EGC and to further assess prognostic factors.
