Background technique

Anterior rectal resection is one of the main surgical methods for treating rectal cancer patients, because it preserves the patient's anus on the basis of radical surgery, but anastomotic leakage is a serious complication of this surgery, with a probability of 7-7 9%. The treatment of anastomotic leakage is usually a diversion operation (such as: enterostomy), and then after 3 to 6 months, wait for the fistula to heal on its own, and then return the enterostomy on the abdominal wall to restore the original intestinal tract structure; the principle is that the abdominal stoma at the proximal end of the intestine diverts the feces, so that the feces no longer pass through the fistula, so that the fistula gradually heals. This traditional treatment method usually makes patients with anastomotic leakage need to bear the blow of a second operation, which not only increases the double pain of the patient's body and mind, but also increases the medical expenses, and even endangers the life of the patient in severe cases.
