BACKGROUND: In recent decades, transanal surgery for rectal lesions has become a valid alternative treatment for the treatment of small lesions of the rectum. Significant benefits in terms of morbidity and mortality are confirmed. There are multiple platforms for transanal surgery but the TEO system® is one of the best known.
METHODS: Between November 2017 and July 2019, 25 patients with rectal lesions suitable to transanal treatment came to our observation. In all reported cases, full-thickness rectum resections were performed. Demographic, histopathological, surgical morbidity/mortality and clinical outcome in all patients who underwent TEO were retrospectively evaluated from a prospectively collected database.
RESULTS: For a period of less than 2 years, 25 rectal lesions were excised by TEO. Sixteen lesions (64%) were low (<4 cm), 7 (28%) were mid-rectal (4-8 cm) and 2 (8%) were in the proximal rectum (>8 cm). Postoperative complications included: 3 (12%) bleedings, and 8 (32%) post-polipectomy syndrome.
CONCLUSIONS: Our initial experience suggests TEO is safe and feasible. Full-thickness resection guarantees adequate deep margins. Moreover, the limited number of cases requires the development of adequate reference centers.
