The lesions that can be cured by early endoscopic cancer can be treated with minimally invasive endoscopic treatment. The treatment of advanced and intermediate cancers is based on surgery, supplemented by chemotherapy, immunotherapy, traditional Chinese medicine and other supportive treatments to increase the surgical resection rate. Reduce the recurrence rate and improve survival. Surgical treatment principles: as far as possible radical treatment, protection of pelvic autonomic nerves, preservation of sexual function, urinary function and defecation function, improve the quality of life. The surgical method is as follows:

1. Right hemicolectomy is suitable for cancers of the cecum, ascending colon and the curvature of the liver in the colon.

 

2. Left colon resection for the descending colon, colon and spleen curvature cancer.

 

3. Transverse colectomy is suitable for horizontal colon cancer.

 

4. The sigmoid colon cancer is swollen to remove the sigmoid colon, but it should also be done with descending colon or partial rectal resection.

 

5. With the principle of surgery with intestinal obstruction, the patient's condition allows for a resection and anastomosis. If the patient is in poor condition, colostomy can be performed first. After the condition is improved, two radical resections are performed.

 

6. The principle of radical surgery cannot be performed. When the tumor is infiltrated extensively or when it cannot be removed with the surrounding tissues or organs, the intestinal canal has obstructed or may be obstructed. It can be used for short-circuit surgery or colostomy. If distant organs metastasize and local tumors still allow resection, local palliative resection can be used to relieve symptoms such as obstruction, chronic blood loss, and infection.
