Background/Aims: Endoscopic submucosal dissection (ESD) has become a standard procedure for the resection of early gastric cancer (EGC). However, the feasibility of ESD for very elderly patients, aged ≥ 80 years, has not been determined. Methodology: The study population included 67 non-elderly (NE) patients aged ≤ 65 years (80 lesions) and 22 very elderly (VE) patients ≥ 80 years (26 lesions) with EGC who underwent ESD and met the criteria for absolute or expanded indications. Eighteen patients (18 lesions) who underwent ESD but did not meet the criteria for absolute and expanded indications were defined as the outside the indications (OI) group. Results: En bloc and complete resection rates were excellent in both the VE and NE groups, without differing significantly. Although the rates of ischemic heart disease and antithrombotic agent use were higher in the VE than in the NE group, procedure-related complication rates did not differ significantly. Of the seven very elderly patients in the OI group, two underwent additional gastrectomy, and the other five were followed-up without surgery. No patient in any group experienced local recurrence, metastasis or disease-specific death. Conclusions: Short- and long-term outcomes of ESD for VE patients with EGC were favorable and did not differ significantly from outcomes in NE patients. ESD may therefore be a good therapeutic option for both VE and NE patients with EGC.
