However, Japanese gastric cancer treatment guidelines list endoscopic submucosal dissection (ESD) as an option for treating limited early gastric cancer cases. ESD can be curative depending on the pathological characteristics of resected specimens. Thus, we aimed to clarify the benefits and disadvantages of preceding ESD for early gastric cancer. Methods We retrospectively analyzed patients who underwent ESD or curative gastrectomy for cT1b gastric cancer with differentiated adenocarcinoma 30 mm or less in diameter. Patients who underwent ESD irrespective of undergoing gastrectomy were assigned to the ESD group (n = 107), and those who underwent gastrectomy without undergoing ESD were assigned to the non-ESD group (n = 181). Clinicopathological characteristics were assessed, and the short-term and long-term outcomes of patients were compared. Results The criteria for curative resection were satisfied by 83 patients (28.8%), and preceding ESD did not affect the surgical outcomes of gastrectomy. Two patients (1.9%) who underwent ESD had an unscheduled total gastrectomy. The en bloc and complete resection rates of ESD were 99.0% and 84.1% respectively. Nine patients (8.4%) experienced intraprocedure perforation and postprocedure bleeding caused by ESD. Overall survival (hazard ratio 1.38 P = 0.302) and cause-specific survival (hazard ratio 0.96 P = 0.944) were comparable between groups. Conclusions The stomach was preserved in 28.8% of patients, and preceding ESD did not show obvious disadvantages. Therefore, diagnostic ESD should be considered as an initial treatment for limited cT1b gastric cancer cases.
