The survival time of elderly people with intestinal perforation is not fixed, it is mainly related to the patient’s physical condition, the cause of intestinal perforation and the treatment measures, etc. For benign diseases, the patient can reach the natural life span after active treatment, if it is caused by malignant tumors, it needs to be decided according to its specific stage and type, and it cannot determine the survival time. For intestinal perforation caused by benign diseases such as intestinal inflammation, ulcers and trauma, after active surgical repair and other treatments in the early stage, the prognosis of patients can be cured, and there is no danger to their lives, and they can reach their natural life expectancy; however, if the treatment is not timely, diffuse peritonitis, infectious shock and so on can occur, and even life-threatening, and the patients can die within a few days. For intestinal perforation caused by malignant tumors, while actively treating intestinal perforation, it is necessary to clarify its staging as well as typing. For patients with low malignant degree and limited lesions, they can be cured after active treatment and reach natural life expectancy, while patients with high malignant degree in middle and late stages can survive for about 1~2 years, or even a few months. To summarize, the survival time of the elderly after intestinal perforation is not fixed, once the intestinal perforation occurs, you need to consult a doctor in time, and be treated by a professional physician for the patient’s condition, so as not to delay the condition.
