- W2920954283 abstract "Introduction: Endoscopic submucosal dissection (ESD) of the stomach lesions offers a higher rate of en bloc resection and a lower rate of recurrence than conventional polypectomy or endoscopic mucosal resection, even for the superficial submucosal cancer. However, the data on its outcome for colorectal lesion is lacking, particularly in the Western countries. Here we present a single center experience of ESD in colorectal lesions. Objective: Evaluate safety and efficacy of ESD in colorectal lesions. Methods: All patients who had ESD for colorectal lesions, including those who had prior unsuccessful attempt of removal by Endoscopic submucosal resection (EMR), from 1/2013 to 6/2017 were included. Various data point and procedural outcomes at 3, 6, and 12 months were extracted. Results: A total of 20 patients, including 12 had prior failed attempted EMR, were included in the study. The average age was 63.5±9.3 years, 45% (9/20) patients were male. 9 patients had the lesion in right colon (7 in ascending colon, 1 on the ileocecal valve and 1 on appendicular orifice), 2 patients had lesions in transverse colon and 9 patients had lesions in the left side of the colon (7 in rectum and 2 in descending colon). The average size of the lesion was 3.6±2.4 cm. 7 patients (35%) had en bloc resection. Out of resected lesions, there were 9 tubular adenomas, 5 sessile serrated adenomas, 1 lipoma, 1 hyperplastic polyp, 1 giant cell tumor, 1 neuroendocrine tumor and 1 intramucosal cancer. The average duration of the procedure was 102.6±46.8 minutes. 12 patients were admitted post-procedure. 2 patients had complications - one had bleeding which stopped spontaneously and the other had contained perforation, which improved with conservative management. A trainee was involved in 50% of the procedures. During 12 month surveillance, 1 patient had recurrent lesion showing adenocarcinoma requiring sigmoidectomy and 1 patient had TVA at resection site which was resected endoscopically. En bloc resection had higher complication rates while piecemeal resection required longer procedure time (Table-1). Conclusion: ESD is a safe and effective method of treatment for colorectal lesions with overall low complication rates and low recurrence rates. Additionally, ESD is a useful salvage therapy in particular for unresectable lesions by EMR.800 Figure 1 No Caption available." @default.
