직장유암종의 내시경 치료 = Endoscopic Resection of Rectal Carcinoid Tumors : Conventional Endoscopic Submucosal Dissection vs Endoscopic Submucosal Resection with Ligation Device

다국어 초록 (Multilingual Abstract)

Purpose: Endoscopic treatment for rectal carcinoids requires special techniques for deeper resection. There are various reports in the literature about endoscopic submucosal resection (ESMR) of small rectal carcinoids using different techniques. The aim of this study was to compare ESMR of rectal carcinoid tumors by endoscopic submucosal resection with ligation device (ESMR-L) with conventional endoscopic submucosal dissection (C-ESD).
Methods: Indication for endoscopic resection was rectal carcinoid measuring less than lcm in diameter located within the submucosal layer. 23 patients with rectal carcinoid tumors underwent endoscopic tumor resection. Group 1 (n=14) carcinoid tumors were treated with ESD using a flex-knife with a conventional single-channel endoscopy. Group 2 (n=9) carcinoid tumors were treated by ESMR-L.
Results: There were no significant differences between group 1 and 2 in the rate of complete resection (92.9%/100%, p=0.609), mean operating time (23.6 ± 14.5 min/ 14.4 ± 5.3 min, p=0.101), and complication associated with the procedure (14.3%/11.1%, p=0.668).
Conclusions: Both ESMR-L and C-ESD have proven to be useful and safe procedures for complete resection of rectal carcinoid tumors less than 10 mm in diameter and had no serious procedure-related complication.
