Background: The aim of this study is to assess postoperative morbidity and mortality in tumors with a proximal margin 15 cm or more from the anal verge operated with transanal endoscopic microsurgery (TEM). Methods: This observational study of consecutive rectal tumor patients undergoing TEM was carried out from July 2004 to June 2017. We compared the results of rectal tumors at distances of ≥15 cm (group A) and <15 cm (group B) from the anal verge. Results: During the study period 667 patients were included: 118 in group A and 549 in group B. In the comparative analysis there were no significant differences in morbidity (p = 0.23), mortality (p = 0.32) or free margin involvement (p = 0.545). Differences were observed in terms of lesion size (p < 0.001), surgical time (p < 0.001) and peritoneal cavity perforation, which were all increased in group A. Conclusion: TEM for lesions in the rectosigmoid junction is feasible and is not associated with higher morbidity or mortality.
