Resection of rectal cancer by incision from the rear of the rectum through the coccyx

Rectal cancer invading the appendix and pelvic tissue is a major problem in rectal resection. It is generally possible to cure the rectal cancer by rectal incision through the posterior rectum. Treatment of diseases: colorectal cancer Indication Rectal cancer has invaded the appendix and pelvic tissue, and non-surgical treatment cannot control cancer cells. Contraindications 1, with systemic diseases, can not tolerate surgery. 2, local infection, not suitable for surgery. Preoperative preparation Appropriate preoperative radiotherapy will not affect tissue repair, and will not increase complications such as local infection and wound dehiscence. Surgical procedure The operation was combined with the perineal and perineal perineum. The patient was first placed in the supine position, and the right lower abdomen was inserted into the abdomen to confirm that there was no distant metastasis and local lymph node metastasis that was difficult to remove. The corresponding position of the upper edge of the tumor in the tibia was determined. The bilateral internal iliac artery was ligated to reduce blood flow and reduce the amount of bleeding. After the abdomen separation is completed, the right lateral position is changed, and the midline incision of the perineum is taken. The tissue attached to the surface of the tibia is separated and the attached tissue is completely exposed. After selecting the resection plane, the humerus is cut or bitten by a bone clamp. The blood is completely stopped, the pelvic cavity is washed, and the drainage is placed. The perineal incision is sutured in one stage. If the tumor is obviously biased to one side, the other part of the tibia can be properly reserved. complication Postoperative intestinal obstruction is also a common complication of gastrointestinal surgery, and sometimes it is impossible to prevent. It is recommended to be conservative first, and most patients can be relieved by conservative treatment without surgery. Abdominal CT and abdominal plain films are recommended for the assessment of obstruction.
