Background/Aims: Although polypoid leiomyomas in the colon and rectum are rare, they are increasingly detected during colonoscopy. The aim of this study was to evaluate the efficacy and clinical outcomes of endoscopic removal for colorectal polypoid leiomyoma.
Methods: Data were retrospectively collected from 22 patients with polypoid leiomyoma arising from the muscularis mucosae in the colon and rectum who underwent endoscopic removal at single referral gastrointestinal endoscopy unit. Colonoscopic findings, endoscopic removal, success rates, complication rates (bleeding or perforation), pathologic characteristics, and recurrence rates were investigated.
Results: Most polypoid leiomyomas were small asymptomatic lesions less than 1 cm. The tumors were located predominantly in the left colon. Ten leiomyomas were removed using cold biopsy forceps, and 12 were resected by conventional polypectomy or endoscopic mucosal resection. All tumors arose from or involved the muscularis mucosa. There were no complications, such as bleeding or perforation. No local remnant lesions were found in 19 patients who underwent at least one follow-up colonoscopy.
Conclusions: This case series represent cases of small colorectal polypoid leiomyoma that were safely removed endoscopically. An awareness of their endoscopic and clinic-pathological characteristics may provide safe treatment strategy for colonic leiomyomatous tumors of similar size in capable hands.
