Generally, fasting is required after gastrointestinal surgery, and the patient is given liquid food after passing gas. After colon cancer surgery, the patient must wait until the intestinal anastomosis heals before eating, which means that the patient can gradually resume eating five days after the surgery.

Nutritional support is given through parenteral nutrition during fasting.

Due to advances in surgical techniques, many patients can start eating earlier after surgery, but this should be decided by the doctor based on the condition.

On the other hand, sometimes the doctor will choose to place a jejunal nutrition tube in the patient. Depending on the recovery of small intestinal peristalsis function, 250 ml of 5% glucose sodium chloride liquid can be slowly dripped through the nutrition tube usually 24 hours after surgery for examination. Check whether the nutrition tube is unobstructed and observe the recovery of intestinal peristalsis. If there is no flatulence, different formulas of enteral nutrition can be selected the next day according to the situation, but the dosage, speed and time of the infusion should be adjusted by the doctor according to the condition.

Studies have shown that starting enteral nutrition as early as possible can help patients recover early intestinal function.

During the recovery period after colon cancer surgery, choose liquid food and a residue-free diet within one month, eat small meals frequently, and avoid overeating; gradually return to a regular diet after one month.

You can eat more whole grains, vegetables or fruits rich in dietary fiber. These foods can stimulate intestinal peristalsis, increase the frequency of defecation, and reduce the residence time of carcinogens and bacteria in the intestines.

However, if the fiber of the food is too long, it can easily become entangled and cause intestinal obstruction, so you should pay attention to mincing it when processing and chewing more when eating. It must be noted that the cellulose in food is actually the cell wall of plants, a tiny structure that can only be seen under a microscope. Cellulose is not found only in long, filamentous foods. Even if vegetables are chopped into puree, cellulose still remains. It will not be destroyed.

In addition, spicy foods such as chilies and peppers may be irritating to the anus and should not be eaten; pickled, grilled, fried, smoked and other foods can easily cause colon cancer, and should be avoided by people with a history of colon cancer; too much oil , especially animal fat, can stimulate the secretion of bile acid in the small intestine. Excessive bile acid content in the intestine can easily cause cancer, so it should also be avoided.

Cooking oil should be mainly vegetable oil, such as olive oil. Deep-sea fish are usually high in omega-3 fatty acids, which help fight inflammation. Folks have always said that eating deep-sea fish is beneficial to wound healing, and there is some truth to it.
