Background/Aims: Endoscopic submucosal dissection (ESD) of gastric tumors in the mid-to-upper stomach is a technicallychallenging procedure. This study compared the therapeutic outcomes and adverse events of ESD of tumors in the mid-to-upperstomach performed under general anesthesia (GA) or monitored anesthesia care (MAC). Methods: Between 2012 and 2018, 674 patients underwent ESD for gastric tumors in the midbody, high body, fundus, or cardia (100patients received GA; 574 received MAC). The outcomes of the propensity score (PS)-matched (1:1) patients receiving either GA orMAC were analyzed. Results: The PS matching identified 94 patients who received GA and 94 patients who received MAC. Both groups showed highrates of en bloc resection (GA, 95.7%; MAC, 97.9%; p=0.68) and complete resection (GA, 81.9%; MAC, 84.0%; p=0.14). There wereno significant differences between the rates of adverse events (GA, 16.0%; MAC, 8.5%; p=0.18) in the anesthetic groups. Logisticregression analysis indicated that the method of anesthesia did not affect the rates of complete resection or adverse events. Conclusions: ESD of tumors in the mid-to-upper stomach at our high-volume center had good outcomes, regardless of the methodof anesthesia. Our results demonstrate no differences between the efficacies and safety of ESD performed under MAC and GA.
