Anastomotic stenosis mainly occurs after gastrointestinal surgery, including gastrointestinal anastomoses as well as anastomoses of the esophagus and jejunum. Patients will have nausea, vomiting, difficulty in swallowing after eating, and even chest pain, abdominal pain and other symptoms may also occur, which will also lead to food retention and secondary infection, patients will also have fever, and in severe cases, abscesses will be formed, which should be actively treated. Mild patients can choose conservative treatment methods, the application of drugs to protect the mucosa of the gastrointestinal tract, the application of drugs to promote gastrointestinal peristalsis, you can choose to stent dilation or placement, and if necessary, need to further choose to select the surgical treatment for anastomosis reconstruction. For the anastomosis of the digestive tract, it is necessary to prevent infection in the postoperative period, because there are some patients who have localized infections that lead to scar stenosis, and postoperative eating should also be careful, avoiding stimulating food, and don’t eat too mucusy food.
