Usually, the prognosis of gastric perforation is better, but the prerequisite is that it needs to be judged according to the infection in the patient’s abdominal cavity and the cause of the patient’s illness. Most gastric perforations are caused by ulcers, which are benign lesions, while perforations caused by gastric cancer are malignant tumors, so the prognosis of the two is different. The prognosis of benign lesions is usually better, while the prognosis of malignant tumors is usually worse. Because the tumor is staged late due to the perforation triggered by gastric cancer, it needs to be judged according to the infection in the patient’s abdominal cavity. If the gastric perforation is longer and the infection inside the abdominal cavity is serious, it will lead to a poorer prognosis for the patient. It is suggested that patients should supplement carbohydrates appropriately in daily life, avoid spicy and stimulating food intake, and quit smoking and drinking can effectively prevent the stomach from being hurt twice. Abdominal discomfort, should promptly consult a doctor, under the guidance of a professional doctor standardized treatment, in order to avoid delaying the condition.
