If the bowel perforation is thoroughly repaired and sutured after surgery, the patient’s condition does not affect normal life expectancy at this time if the bowel is not cancerous but only a chronic ulcerative lesion. It is very common for patients to return to a normal state and survive for 40-50 years after surgery. If the patient’s intestinal perforation is repaired and later gastroscopic review reveals that the local perforation is caused by neoplastic lesions, the tumor has often invaded the whole intestinal wall and the surrounding lymph nodes, which is a middle to late stage neoplastic lesion, and the patient’s prognosis is often poor, and the patient’s survival time may only be 1-2 years. Therefore, patients with intestinal perforation need to undergo gastroscopic review in time to clarify the specific cause of perforation and take active and effective treatment methods to avoid serious complications.
