A study comparing transanal endoscopic microsurgery (TEM) and single-port robotic transanal minimally invasive surgery (SP rTAMIS) for rectal lesion excision found that SP rTAMIS offers shorter operative times and lower postoperative morbidity. Both methods had similar rates of positive margins and piecemeal resection, with no intraoperative complications in either cohort. SP rTAMIS had fewer postoperative complications (9% vs. 20%, p = 0.031) and no mortalities. These findings support SP robotics as a promising alternative to TEM for rectal lesion excision.
