How can I save my anus from rectal cancer? The struggle that patients with rectal cancer have with surgery is sometimes not so much about the trauma of the surgery, the risks and how great the risk of recurrence is after surgery. A large part of it comes from the anus that needs to be removed for the surgery. In rectal cancer, especially low-grade rectal cancer and ultra-low-grade rectal cancer, which is less than 8 centimeters or 5 centimeters from the dentate line, the anus needs to be removed and an artificial anus made in the abdominal wall to ensure complete surgical cure and the safety of the anastomosis. For patients, the artificial anus may cause a decrease in quality of life, and some patients even have a certain psychological burden. Therefore, it is very important for patients unfortunate enough to have rectal cancer to preserve the anus as much as possible. From the medical point of view, what doctors can provide is only perfect surgical techniques, advanced anastomotic instruments and advanced concepts of pre-surgical radiotherapy to achieve tumor reduction. However, it is the patient’s own factors that can better determine whether the anus can be preserved or not. The success rate of anal preservation for low and ultra-low tumors is significantly lower than that for tumors above 8 cm from the dentate line; 2. the degree of local infiltration of tumor The infiltration of tumor into the surrounding area often requires expansion of the scope of surgery; 3. the area of lymph node metastasis There are several ways of lymphatic metastasis for rectal cancer, and the ways of metastasis for tumors below the peritoneal fold are more complicated; 4. other factors including the sensitivity of preoperative radiotherapy and chemotherapy, the anatomical type of the pelvis, and the sensitivity of preoperative radiotherapy. sensitivity, anatomical type of pelvis, etc. What patients need to do is to try to detect and treat as early as possible. For abnormal bowel movements, especially bloody stools, black stools, small stools, constipation, severe prolapse of hemorrhoids, etc., do not be paralyzed and seek timely medical consultation, and patients over 45 years of age need to take colonoscopy as a routine means of examination for colorectal disorders. The incidence of rectal cancer is increasing, we need a healthy lifestyle and living environment, and once the disease is treated with a positive attitude, I believe that one day we will conquer the tumor.
