After bowel cancer surgery, the exact frequency of colonoscopy should be analyzed according to the stage of bowel cancer after surgery and whether the total colonoscopy is completed before surgery, etc. However, if the colonoscopy is not completed before surgery or because the mass is huge, it is usually enough to check the colonoscopy in the first year after surgery. If colonoscopy has been completed before operation, generally, colonoscopy can be checked once in the first year after operation, and if there is no problem, it can be checked again after 5 years; however, if colonoscopy has not been completed before operation or colonoscopy has not been completed because of huge mass, the first colonoscopy needs to be done in 3-6 months after operation. Since recurrence and metastasis of bowel cancer may occur, thus in daily life, in addition to regular follow-up, patients need to observe themselves carefully, and if they have any uncomfortable symptoms, such as abdominal distension, nausea, vomiting, etc., they should immediately seek medical checkups and take different measures according to the specific conditions of their bodies in order to avoid undesirable situations. Patients are advised to eat less greasy and hard-to-digest food, such as fried chicken and oil cake, and can eat nutritious and easy-to-digest food, such as egg custard and lean minced meat. Likewise to develop good eating habits, you can eat small meals, but need to avoid overeating to avoid discomfort.
