N/A Rectal cancer. Intervention 1: Intervention group: Appendicostomy: Surgery is done in two steps. First, after the release of the disending colon, the inferior mesenteric artery and vein are high ligated. The sigmoid colon is removed from the middle portion. Then the perineal phase is done and The complex of anal sphincter and the rectum and distal sigmoid are resected and left side colostomy are inserted and perineal incision are closed. At the same time, an appendicectomy is inserted for patient.To do this, the appendix is ​​dissected and the longitudinal insision of the distal appendices is done,then in right lower quadrant skin U shape insision is performed and anti mesenteric edges are sutured to the skin with 4-0 absorbable. A small catheter is placed in the appendicectomy for a week and the first antegrade enema with one liter of water is done. The necessary care and method of using appendicectomy is given to patients before discharge. Intervention 2: Control group: without appendicostomy: First, after the release of the disending colon, the inferior mesenteric artery and vein are high ligated. The sigmoid colon is removed from the middle portion. Then the perineal phase is done and The complex of anal sphincter and the rectum and distal sigmoid are resected and left side colostomy are inserted and perineal incision are closed.
