BACKGROUND AND OBJECTIVES: Transanal endoscopic operation (TEO) is a minimally invasive technique used for local excision of benign and selected @entity5 . The purpose of this study was to investigate the feasibility, safety, and oncological outcomes of the procedure and to report the experience in 3 centers. METHODS: Retrospective review of a prospectively collected database was performed of all @entity1 with benign lesions or <= cT1N0 @entity5 who underwent TEO with curative intent at 3 Belgian centers (2012 through 2014). RESULTS: Eighty-three @entity1 underwent 84 TEOs for 89 rectal lesions (37 @entity652 , 43 @entity420 , 1 @entity674 , 1 @entity8799 , and 5 scar tissues). Operative time was associated with lesion size (P < .001). @entity260 occurred in 13 @entity1 : 7 @entity548 , 1 @entity293 , 1 urinary retention, 2 abscesses, 1 @entity850 , and 1 entrance into the peritoneal cavity. Median hospital stay was 3 days (range, 1-8). During a median follow-up of 13 months (range, 2-27), there was 1 recurrence. CONCLUSION: Although longer follow-up is still necessary, TEO appears to be an effective method of excising @entity5 and low-risk T1 @entity189 of the rectum. However, TEO should be considered as part of the diagnostic work-up. Furthermore, the resected specimen of a TEO procedure allows adequate local staging in contrast to an endoscopic piecemeal excision. Nevertheless, definitive histology must be appreciated, and in case of unfavorable histology, radical salvage resection still has to be performed.
