The commonly used treatment for advanced colorectal cancer is a comprehensive treatment based on surgery and chemotherapy, which is summarized as follows:

Surgery for colorectal cancer

Treatment of colorectal cancer Surgical resection remains the main treatment for colorectal cancer, and can be supplemented by chemotherapy, biological therapy, and other supportive treatments.

Preoperative preparation: In addition to routine preoperative preparation, colon surgery must be well prepared for the intestine, including

① Clean the intestines: Eat a diet with little or no residue two days before the operation; take laxatives 1 to 2 days before the operation. If there is constipation or incomplete intestinal obstruction, take the medicine a few days in advance as appropriate; cleansing enema can be performed one or several days before the operation depending on whether there is difficulty in defecation.

② Intestinal disinfection: Kill pathogenic bacteria in the intestine, especially common anaerobic bacteria such as Bacteroides fragilis, and Gram-negative aerobic bacteria. The former mainly uses metronidazole, and the latter can use sulfonamides, neomycin, erythromycin, kanamycin, etc. Adequate intestinal preparation can reduce intraoperative contamination, reduce infection, and facilitate healing.

At present, some hospitals at home and abroad have adopted the method of whole intestinal lavage for intestinal preparation. The method is to drip or take a special lavage solution (containing a certain concentration of electrolytes and intestinal disinfectants to maintain a certain osmotic pressure) through a stomach tube, with a dosage of 4 to 8 liters, and squat on a defecation device. It can achieve the purpose of intestinal cleaning and disinfection at the same time.
