Colorectal tumor surgery is only the first peak that patients climb over on the way to fight against cancer. Post-operative follow-up can detect recurrence and metastasis at an early stage and carry out the next treatment as soon as possible, and can detect and treat intestinal diseases (polyps, heterochronous tumors, etc.), guide patients’ diet, and comfort patients’ psychology, etc. For the postoperative follow-up of such tumor surgery patients, our hospital has a special follow-up office; then what should patients pay attention to in the postoperative follow-up? According to the current medical evidence, most of the colorectal tumor recurrence and metastasis occur within 5 years after surgery, and 2 years after surgery is the high incidence period, which greatly affects the effect of treatment and survival rate of patients, so regular review is the most important of postoperative recovery. According to the rule of recurrence and metastasis after colorectal cancer surgery, the recommended review program after colorectal cancer treatment according to the 2015 China Colorectal Cancer Diagnostic and Treatment Standard of the Ministry of Health is as follows: 1. medical history and physical examination, once every 3-6 months for 2 years, then once every 6 months for a total of 5 years, and once every year after 5 years; 2. monitoring CEA and CA199, once every 3-6 months for a total of 2 years then once every 6 months for a total of 5 years and annually after 5 years; 3. Abdominal and/or pelvic ultrasound every 3-6 months for 2 years and then every 6 months for a total of 5 years and annually after 5 years Chest X-ray every 6 months for 2 years, then once a year after 2 years; 4. CT or MRI of the chest, abdomen and/or pelvis once a year; 5. Colonoscopy within 1 year after surgery, if there is any abnormality, review within 1 year; if no polyp is seen, review within 3 years; then once every 5 years, resection is recommended for any large intestinal adenoma that appears on follow-up examination. However, it is not enough just to master the above review scheme, there are several details that need to be paid particular attention to. ① For those who have not completed the whole colon examination due to tumor obstruction before surgery, it is recommended to perform colonoscopy 3-6 months after surgery; ② CT of thoracoabdominopelvic cavity is better than chest X-ray and ultrasound of abdominopelvic cavity; ③ The importance of “one finger” should not be neglected; postoperative anal finger examination can check complications such as anastomotic stenosis, especially low level Patients with protective stoma after rectal cancer surgery should pay more attention to regular postoperative rectal examination; anastomotic stenosis is simple to deal with in the early stage, but very difficult to deal with once the stenosis is aggravated to complete closure! Diet 1. Strictly controlled diet within one week after surgery – liquid diet is advisable: ① Fasting within 24-48 hours. Premature eating will result in abdominal distension, vomiting and other adverse reactions, and during this period of time, it is necessary to provide nutrients and energy through peripheral intravenous rehydration; ② Full liquid diet on the 3rd to 4th day. After the intestine restores its function and the anus begins to exhaust a small amount of food, choose rice soup (combined with diabetes as much as possible), enteral nutrition preparations (diabetics can choose diabetes-specific enteral nutrition preparations, such as Yilijia SR), gradually transition to meat porridge soup (take no dregs soup), pork ribs porridge soup (take no dregs soup), dilute lotus root powder, vegetable juice, etc.; ③ the 5th-6th day to eat a small amount of semi-liquid. Avoid: Before the intestinal function is restored after intestinal surgery, gas-producing foods should be avoided, such as milk, soy milk, cow’s milk, all non-fluid solid foods, foods containing more dietary fiber and foods that are too greasy and thick should not be used. 2.The diet should be properly controlled on the 7th-14th postoperative days – semi-liquid diet Appropriate: The 7th-14th day is mainly liquid. Most of the patients have basically recovered their intestinal function, so there is no need for intravenous infusion of fluids and nutrients, and the patients can completely eat by mouth, which can last for 5-7 days. At this time, food is mainly liquid. Enteral nutrition preparations are supplemented between meals to ensure that the patient’s energy and nutrient needs are met while reducing the burden on the digestive tract. Avoid: Hard and undigestible food should not be consumed at this time; strong and stimulating condiments should not be used. 3, 14-90 days after surgery to control part of the diet as appropriate – normal meals Because some patients do not dare to eat normally or doctors forget to guide, in a longer period of time after surgery to liquid food, the patient is in a “starvation state”, which leads to weight loss, physical decline, so that the patient’s health status. This leads to weight loss and physical fitness loss, and prevents good recovery of physical health. Desirable: After two weeks postoperative, pay attention to the variety of food, coarse and fine, reasonable cooking methods, color and flavor, to ensure a balanced intake of nutrients. Avoid: food that is difficult to digest, chili, garlic, mustard, excessively hard food (walnuts, raw peanuts, dried almonds, etc.) food, especially patients with intestinal stoma should pay attention to eat little or no food. 4, 90 days after surgery, due to the surgery caused by the traumatic inflammation of the abdominal cavity basically disappeared, the abdominal cavity of each organ function are completely restored, you can be like a normal person: “what you want to eat, eat anything”! 5, post-operative diarrhea is suitable for refined rice, refined noodles, lean pork and other low-fiber, low-fat, lactose-free meals based on boiling and steaming. Do not eat foods containing high fat, fried and thick condiments, nuts and high-fiber vegetables. 6.Post-operative constipation is advisable to replace fine food with rough food, eat more vegetables and fruits with skin, and take auxiliary drugs such as lactulose if necessary. Avoid spicy, fried and greasy food. Psychology Colorectal tumor is one of the highly prevalent malignant tumors in China. Its diagnosis and treatment produce extremely bad trauma to patients’ psychology, especially the artificial anus (stoma) will have great influence on patients’ spirit and normal life after surgery. With the development of treatment technology, the survival period of colorectal tumor patients is getting longer and longer, but the problem of low quality of life with disease survival period still prevails. Due to the change of stool function and decline of social function, patients have various bad emotions such as irritability, anxiety, insomnia, depression and frustration, and even some individual patients choose to commit suicide, which is regrettable! Therefore, the psychological health of patients is also a part that cannot be ignored. ①Support and encouragement from friends and relatives are essential; ②If necessary, ask professionals for psychological counseling and psychological guidance, especially for patients whose condition requires failure to retain anal function; ③The correct guidance of medical staff can help relieve patients’ embarrassment and low self-esteem caused by stoma, and patients and their families can be guided to participate in “stoma life (3) Proper guidance by medical and nursing staff can help relieve patients’ embarrassment and inferiority due to stoma, and patients and their family members can be guided to participate in “stoma life.
