Objective Superficial colorectal tumors can be treated effectively by endoscopic submucosal dissection ( ESD ). Few data are available on using ESD for residual or recurrent tumors after the first endoscopic resection. This study aimed to evaluate the efficacy of ESD for these lesions. Methods In all, 28 patients with residual or recurrent superficial colorectal tumors were referred to the K obe U niversity H ospital for ESD . The therapeutic outcomes and the possible factors predictive of procedure difficulties for ESD were analyzed. Results In total, 27 (96.4%) patients were successfully treated using ESD. There was no related immediate complication. One patient had a delayed perforation which was then treated surgically. En bloc R0 resection was possible in all the patients and curative resection in 26 patients (92.9%). One invasive cancer was treated surgically. More than one previous endoscopic resection was the only significant predictive factor for the difficulty in performing ESD . None of the patients experienced recurrence during a follow‐up of 22 months (range 3–41 months). Conclusions The use of ESD allowed a high rate of en bloc resection for residual or locally recurrent colorectal tumors. Furthermore, these lesions should be treated by ESD as a first‐line treatment.
