The survival time of patients after gastric perforation surgery is related to the disease that caused the perforation. Gastric perforation caused by benign disease may not affect life expectancy after surgery. Gastric perforation caused by malignant disease also has a different survival time depending on the stage of the tumor, generally advanced tumors may be 2-3 years. There are many causes of gastric perforation, which are generally divided into benign perforation and malignant perforation. Benign perforation is mainly gastric perforation caused by peptic ulcer. After timely surgery for gastric perforation caused by ulcer disease, the ulcer can be completely cured with taking treatment and does not affect life expectancy. Of course, if the patient’s surgery is not timely, or the condition is serious, the stomach acid outflow causes intestinal spasm, and even causes internal organ damage, the recovery time after surgery is longer. If the gastric perforation is caused by malignant tumor, most of them are caused by advanced gastric cancer, and usually radical gastric cancer surgery should be performed after the gastric perforation repair. If the gastric cancer is in early stage, it can survive for a longer time after gastric resection. However, most patients with gastric cancer causing gastric perforation have advanced gastric cancer, so the survival time after gastric perforation surgery is relatively short, usually 2-3 years. Therefore, patients should consider having a gastroscopy if they feel any discomfort in the stomach or during health check-ups. If there is gastric ulcer disease, timely treatment can prevent the occurrence of gastric perforation. Gastroscopy can detect early gastric cancer, and early treatment can have better therapeutic effect. In addition, avoid overeating and drinking a lot of alcohol to prevent gastric perforation.
