How does rectum cancer do?
summary
Rectal cancer refers to the cancer from the dentate line to the junction of rectum and sigmoid colon. It is one of the most common malignant tumors in digestive tract. The location of rectal cancer is low, so it is easy to be diagnosed by digital rectal examination and sigmoidoscopy. However, because of its deep location in the pelvic cavity and complex anatomical relationship, the operation is not easy to complete and the recurrence rate is high. How does rectum cancer do? Let's talk about my views.
How does rectum cancer do?
First, transabdominal perineal resection (Miles operation) is suitable for lower rectal cancer less than 7cm from the anal margin. The scope of resection includes sigmoid colon and its mesorectum, rectum, anal canal, levator ani muscle, tissues in ischiorectal fossa, skin and blood vessels around anus, ligation and cutting at the root of inferior mesenteric artery or below the left colon artery, and dissection of corresponding para arterial lymph nodes. A permanent colostomy (artificial anus) was performed on the abdomen. The operation is complete and the cure rate is high.
Second, sphincter preserving resection of rectal cancer is suitable for early rectal cancer 7-11cm from anal margin. If the tumor is large, the degree of differentiation is poor, or the main upward lymphatic vessels have been infarcted by the cancer cells and have lateral lymphatic metastasis, the resection is not complete, and the combined abdominoperineal resection is still better. The current sphincter preserving rectal cancer resection methods include anastomotic device, transabdominal low resection transanal eversion anastomosis, transabdominal free transanal pull-out resection anastomosis, transabdominal transacral resection and so on.
Thirdly, radiotherapy plays an important role in the treatment of rectal cancer. At present, it is considered that the survival time of patients with locally late middle and low rectal cancer is longer than that of patients with surgery followed by radiotherapy. Postoperative chemotherapy is recommended for patients with rectal cancer whose postoperative pathological stage is stage II and stage III. The total chemotherapy time is half a year.
matters needing attention
Avoid eating high-fat food for a long time, and eat more fiber containing food to keep the stool unobstructed. Eat more fresh vegetables, fruits, garlic, tea and other natural anti-cancer food, appropriate supplement of food containing vitamin A, B12, C, D, e and folic acid. Pay attention to regular living habits and control weight. Avoid staying up all night, otherwise it will affect the large intestine timely discharge of toxic substances, resulting in a high incidence of cancer.
