Abstract


Tumors at the level of the anorectal junction had required abdominoperineal resection (APR) to achieve an adequate resection margin. However, in the cases of tumor invading ipsilateral levator-ani muscle (LAM), en-bloc resection of the rectum with LAM including tumor would be possible. This video is to show the critical anatomic steps of this procedure. A video was produced from the robotic right partial excision of LAM (PELM) performed in a 57-year-old female patient with rectal cancer at 3 cm from the anal verge, invading the ipsilateral anorectal ring, who had received neoadjuvant chemoradiotherapy. The patient discharged at postoperative day 8 without complication. The pathology of the surgical specimen revealed ypT3N1bM0. The secure resection margin from the tumor was achieved. Robotic PELM is the sphincter-preserving technique that can be an alternative treatment option for low rectal cancer invading the ipsilateral LAM, which has been an indication for APR or extralevator APR.
