Abstract: Background Minimally invasive treatment of early-stage rectal lesion has presented good results, with lower morbidity than surgical resection. Transanal endoscopic microsurgery (TEM) and transanal minimally invasive surgery (TAMIS) are the main methods of transanal surgery. However, endoscopic submucosal dissection (ESD) has been gaining ground because it allows en bloc resections with low recurrence rates. The aim of this study was to analyze ESD in comparison with transanal endoscopic surgery. Methods We searched MEDLINE, EMBASE, SciELO, Cochrane CENTRAL, and Lilacs/Bireme with no restrictions on the date or language of publication. The outcomes evaluated were recurrence rate, complete (R0) resection rate, en bloc resection rate, length of hospital stay, duration of the procedure, and complication rate. Results Six retrospective cohort studies involving a collective total of 326 patients-191 in the ESD group and 135 in the transanal endoscopic surgery group were conducted. There were no statistically significant differences between the groups for any of the outcomes evaluated. Conclusions For the minimally invasive treatment of early rectal tumor, ESD and surgical techniques do not differ in terms of local recurrence, en bloc resection rate, R0 resection rate, duration of the procedure, length of hospital stay, or complication rate, however, evidence is very low.
