    Abstract:
    PURPOSE: Endoscopic transanal resection of rectal adenomas and other presumably benign lesions is not widespread. The purpose of this study was to evaluate the efficacy and the safety of endoscopic transanal resection. METHODS: Patients who underwent endoscopic transanal resection at three Stockholm hospitals between 1993 and 2004 were studied retrospectively with respect to patient and lesion characteristics, complications, follow-up time, and recurrence rates. RESULTS: One hundred eighty endoscopic transanal resection procedures were performed in 131 patients. The tissue diagnosis was adenoma in 160 operative cases, cancer in 12 operative cases, and hyperplasia, fibrosis, or normal mucosa in the remaining 8 operative cases. Among the patients with rectal adenomas, one endoscopic transanal resection was sufficient in 77 cases and in 16 cases the surgery was performed in more than one session because of the large size of the adenoma. In 27 cases there were recurrences that needed additional endoscopic transanal resection or other surgery. The median time until recurrence was seven months, but there were no recurrent rectal carcinomas. In 16 operative cases there were complications. Two patients had to undergo a Hartman's procedure as a result of a bowel perforation, and one patient had to be reoperated on because of bleeding. There were no perioperative deaths. The median follow-up time without recurrence was 32 (range, 0-67) months. CONCLUSIONS: Endoscopic transanal resection is a feasible and oncologically safe option for treatment of rectal adenomas, especially in cases where conventional transanal resection or transanal endoscopic microsurgery are unavailable or unsuitable because of the characteristics and localization of the lesion.
