The anastomosis of intestinal resection anastomosis usually heals in about 10 days after the operation, the exact time is related to the scope of intestinal resection, the individual’s physical condition and so on. The anastomosis of intestinal resection is divided into four layers of the intestinal wall, the epithelial layer can heal in about a week, and the muscle layer is a little slower. Therefore, a certain degree of healing can be formed in ten days after the operation, and the patient can take a small amount of water and liquid food. However, the specific healing time is related to the length and location of the intestinal resection, the patient’s individual physical condition, and the postoperative nutritional care status. Patients with malnutrition, diabetes mellitus, cirrhosis and other diseases will have a slightly longer healing time. Patients can return to normal life in about 1-2 months after intestinal resection anastomosis. During this period, patients should undergo regular checkups and follow the doctor’s instructions to perform a small amount of activities and eat a light diet to promote recovery.
