{Abstract}: <B>OBJECTIVE: </B>The aim of this study was to investigate whether there was a difference in overall survival (OS) between elderly patients with early gastric cancer (EGC) who underwent endoscopic submucosal dissection (ESD) and those who underwent surgery.<BR><B>METHODS: </B>Four databases including PubMed, Embase, the Cochrane Library and CKNI were searched on March 20, 2023. The characteristics of the studies and the baseline information of the patients, including their medical histories, postoperative data, and prognoses, were recorded. Odds ratios (ORs) or mean differences (MDs), and 95% confidence intervals (CIs) were pooled up to calculate baseline information and postoperative information. Hazard ratios (HRs) and 95% CIs were used to calculate the prognosis of the patients. Stata V16.0 software was used for the data analysis.<BR><B>RESULTS: </B>A total of eight studies involving 2334 patients were included for the data analysis in this study. After pooling up the data, we found that the ESD group had lower Eastern Cooperative Oncology Groupprevious (ECOG) scores (OR = 0.33, 95% CI = 0.17 to 0.65, I2 = 59.69%, P = 0.00 < 0.05) than the surgery group. There were significant differences in the operation time (MD = -3.38, 95% CI = -5.19 to -1.57, I2 = 98.31%, P = 0.00 < 0.05), length of hospital stay (MD = -3.01, 95% CI = -4.81 to -1.20, I2 = 98.83%, P = 0.00 < 0.05) and hospitalization expenses (MD = -2.67, 95% CI = -3.59 to -1.75, I2 = 93.21%, P = 0.00 < 0.05) between the two groups. The ESD group had a lower OS rate (HR = 2.81, 95% CI = 2.20 to 3.58, I2 = 12.28%, P = 0.00 < 0.05).<BR><B>CONCLUSIONS: </B>Elderly patients with EGC who underwent ESD had a significantly worse OS rate than those who underwent surgery. If the patient's condition was suitable, surgery was still recommended for these patients.
