The extent and location of the cut depends on the extent of the cut. 1. If the cut is in the upper esophagus, fasting is required, along with symptomatic treatment with rehydration fluids and drugs to suppress gastric acid. 2. If the cut is at the cardia, it may lead to gastrointestinal hemorrhage. It is necessary to determine the amount of bleeding, or further hospitalization for observation, as well as to give blood transfusion, rehydration, and symptomatic treatment to maintain vital signs. 3. If the cut is in the middle part of the esophagus, submucosal rupture may occur, leading to perforation of the esophagus. Perforation often leads to an esophageal airway fistula, which can cause local infection. As long as the esophageal cut is relatively mild, it can be treated symptomatically with oral medication. If it is more serious, it needs to be hospitalized for observation, usually after 2-3 weeks of time also need to review the gastroscopy, according to the gastroscopic situation and then further assistance in diagnosis and treatment.
