In cases of low risk T1 local excision facilitates rectal-preserving treatment. Transanal minimally invasive surgery (TAMIS) is the most recent alternative developed for local excision. In this study we evaluate the results after implementing TAMIS as the routine procedure for local excision of rectal neoplasms.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods<\/jats:title>\n                <jats:p>All patients who underwent TAMIS from January 2016 to January 2020 at St. Olav\u2019s University Hospital were included, and clinical, pathological and oncological data were prospectively registered. The primary endpoint was local recurrence, and the secondary endpoint was complications.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Results<\/jats:title>\n                <jats:p>There were 76 patients (42 men, mean age was 69\u00a0years [range 26\u201388\u00a0years]), The mean tumour level was 82\u00a0mm (range 20\u2013140\u00a0mm) from the anal verge measured on rigid proctoscopy, and mean tumour size was 32\u00a0mm (range 8\u201373\u00a0mm). Three patients experienced complications needing intervention (Clavien\u2013Dindo\u2009&gt;\u20093A). Seventeen patients had rectal adenocarcinoma, 9 of whom underwent R0 completion total mesorectal excision (cTME). Fifty-five patients had an adenoma, 3 of whom developed recurrence (5.4%) within 12\u00a0months. All recurrences were treated successfully with a new TAMIS procedure. In addition, TAMIS was used in treatment of 2 patients with a neuroendocrine tumour, 1 patient with a haemangioma and 1 patient with a solitary rectal ulcer.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>TAMIS surgery is associated with a low risk of complications and a low recurrence rate in rectal neoplasms.
