The aim of this study is to evaluate TEM\/TEO in lesions of this type from the point of view of morbidity, mortality and the quality of the pathology specimen.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>This is an observational study with prospective data collection from June 2004 to July 2018. Two groups are defined: group A (rectal tumors with proximal margin between 0 and \u22644\u00a0cm from anal verge) and group B (distal margin\u2009&gt;\u20094\u00a0cm from anal verge). A technical description is provided; resections and postoperative complications in both groups are compared.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>During the study period, 757 patients underwent TEM\/TEO. Finally, 692 patients were included, 192 patients in group A and 500 patients in group B. An en bloc surgical specimen was obtained in 176\/192 patients (91.7%), although the defect was completely sutured in 132 (68.8%).
