The objective of this study was to evaluate the safety and effectiveness transanal endoscopic microsurgery for rectal neuroendocrine tumours.A retrospective cohort all pathology-confirmed tumours treated by from April 2007 December 2020 at a tertiary care centre performed. Demographic, clinical, radiographic pathological data were collected. Characteristics patients with recurrence examined. Descriptive statistics performed.There 58 excision. Referrals primary excision (15, 25.9%), completion re-excision after incomplete removal (38, 65.5%) or locally recurrent (5, 8.6%). mean age 56.4 ± 11.9 years 26 women (44.8%). Mean tumour size 7.4 3.8 mm (range 1.0-15.0 mm). Most (86.4%) Grade 1 tumours. operative time 37.2 17.2 min 56 (96.6%) discharged on same day. All had negative margins final pathology. Of 38 who referred removal, eight (21.1%) residual Three recurrences diagnosed 2.1, 4.5 12.5 2 tumours, less than cm, radiographically.To date, is largest North American looking This technique effective in managing primary, incompletely excised good clinical oncological outcomes.
