It often requires extensive resection of the perianal skin and rectum. Many studies have shown the efficacy of laparoscopic abdominoperineal resection for lower rectal cancer. However, extensive resection of the dorsal side of the perineal skin is difficult in the lithotomy position. We report a laparoscopic abdominosacral approach using the jackknife position for perianal Paget's disease.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and Surgical Technique<\/jats:title><jats:p>Surgery was started using the lithotomy position, and total mesorectal excision with central lymphadenectomy was performed laparoscopically. Pelvic floor muscles were divided 2\u00a0cm away from the rectum. The sigmoid colon was then divided with a linear stapler, and a terminal colostomy was made. The sacral approach was then followed with the patient placed in a jackknife position. A skin incision was made 1\u20102\u00a0cm from the negative margin confirmed by preoperative mapping biopsy and resected en\u2010bloc. We used this approach in two patients with a mean operative time of 483\u2009minutes, including 53.5\u00a0minutes for the position change. All tumor margins, including the skin, were cancer\u2010free, and primary wound closure was possible in both of the cases.
