Core Tip

Core tip: No previous reports have described the clinical outcomes of endoscopic submucosal dissection using the Clutch Cutter (ESDCC) for older patients with early gastric cancer (EGC). The present study evaluated the clinical outcomes, including medical economics, associated with ESDCC for older patients. There was no significant difference between older patients and non-older patients in the rate of ESDCC-related complications. There was also no significant difference between older and non-older patients in the mean duration of hospitalization and medical economics. We conclude that ESDCC is safe and effective for older and non-older patients with EGC.
