The median distance of tumor from anal verge was 11\u2009cm. Ordinarily, a multiport platform with three channels was placed in the 3\u2010cm umbilical incision, and another 5\u2010 or 12\u2010mm port was placed in the right lower abdomen.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The median operative time, amount of intraoperative bleeding, number of harvested lymph nodes, and length of distal margin were 272\u2009min, 10\u2009mL, 22 nodes, and 4.0\u2009cm, respectively, and there was one (2%) patient with involvement of the radial margin. There were eight patients (13%) who required additional ports, and one patient (2%) who converted to open surgery. Intra\u2010 and postoperative complications occurred in one (2%) and 12 patients (19%), respectively. The median length of postoperative hospital stay was 8\u2009days. The median follow\u2010up period was 79\u2009months, and incisional hernia was observed in 3 (5%) patients at the platform site not the port site, and cancer recurrence occurred in four patients (6%). The 5\u2010year relapse\u2010free and overall survival rates were 100% and 100% in the patients with pathological Stage I disease, 94% and 100% in the patients with pathological Stage II disease, and
