ABSTRACT
BACKGROUND/AIMS:
Endoscopic submucosal dissection (ESD) of a colorectal tumor is technically difficult. This study aimed to analyze the clinical outcomes of superficial large rectosigmoid tumors after ESD.METHODS:
Medical records of 15 patients with large rectosigmoid tumors (more than 30 mm), in which ESD performed, were reviewed retrospectively.RESULTS:
The mean tumor size was 42.5+/-14.3 mm (range, 30~78 mm). A histological examination revealed a well-differentiated adenocarcinoma in five cases (33.3%), adenoma with high-grade dysplasia in six cases (40%), and low-grade dysplasia in four cases (26.7%). The mean procedural time was 90.5+/-60.7 min (range, 22~246 min). The en bloc resection rate was 86.7%, and the complete resection rate 100%. The lateral resection margin was positive in four cases (26.6%), but no cases with a positive vertical margin were observed. Bleeding occurred in three cases (20%), and all were treated successfully using endoscopic measures. Perforations occurred in three cases (20%); two cases were treated by clipping and the other by a laparotomy.CONCLUSIONS:
ESD is a treatment option for superficial large rectosigmoid tumors. Further studies with larger cases and a longer term follow-up are needed to establish the efficacy and safety of ESD for colorectal tumors.
