After identifying the cause of postoperative feeding difficulty of esophageal cancer, anastomotic dilatation, drugs, placing nutritional tube, radiotherapy and other methods can be chosen. 1. Anastomotic dilatation: for the feeding difficulty caused by anastomotic stenosis, anastomotic dilatation under gastroscope is often chosen after a period of time of postoperative period, and the symptom can be relieved to a certain extent after several dilatations at regular intervals. 2. Drugs: When the difficulty in eating is caused by insufficient gastrointestinal power, the patient can take drugs to promote gastrointestinal power, such as mosapride, under the guidance of specialized doctors, which can relieve the symptoms. 3. Placement of nutritional tube: When the symptoms of eating difficulty are serious, nutritional tube can be placed in the gastrointestinal tract to inject nutrition into the body and ensure energy supply. 4. Radiotherapy and other systemic anti-tumor treatment: if the tumor has metastasized to the mediastinum or both lungs, and there are compression symptoms leading to eating difficulty, systemic anti-tumor treatment is needed. Local radiotherapy can improve the symptoms of eating difficulty, and systemic chemotherapy is feasible for patients with advanced stage, and targeting and immunotherapy can also be combined. When the symptom of difficulty in eating after esophageal cancer surgery occurs, it is recommended to consult the doctor in time for early treatment and do not take medicine without authorization.
