Does operation treat colon cancer to have effect

summary

In the past, I didn't know much when I was studying. I often didn't eat for examination. As a result, my intestines and stomach were not very good and I always had diarrhea. Recently, I found out that I had colon cancer and had been treated in the hospital. Now let's talk about how to treat colon cancer surgically.

Does operation treat colon cancer to have effect

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: transabdominal low resection and extraperitoneal one-stage anastomosis, also known as anterior resection of rectal cancer (Dixon operation), is suitable for upper rectal cancer more than 12 cm away from the anal margin. Most of the sigmoid colon and rectum are removed in the abdominal cavity, and the rectum below the peritoneal reflexed part is free, and the sigmoid colon and rectum resection end are anastomosed outside the peritoneum. This operation is less invasive and can retain the original anus, which is ideal. If the tumor is large and has infiltrated the surrounding tissue, it should not be used.

Third, sphincter preserving resection 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.

matters needing attention

At present, the survival time of colorectal cancer is relatively good. The prognosis should be reexamined and the regular life, especially the diet, should be paid attention to.
