Whether or not a hernia will become necrotic after it has fallen depends largely on whether or not there is an incarcerated hernia. If it is an incarcerated hernia, it will cause necrosis of the intestine about six hours after the contents of the hernia have fallen out. If it is not an incarcerated hernia, it will not cause necrosis. Hernia is a common clinical symptom in general surgery, and is typically characterized by the appearance of a lump in the groin area, which appears when standing or moving, and is relieved by rest or lying down. If the mass cannot be returned after the appearance of the mass, it is considered to be an incarcerated hernia. In this case, it is necessary to pay close attention to this situation, and promptly go to the general surgery department of the hospital for ultrasound examination of the inguinal area to make it clear. If the diagnosis of incarcerated hernia is confirmed, emergency surgical treatment is needed. After completing the relevant preoperative examinations, including blood routine, coagulation and electrocardiogram, emergency surgical treatment is needed to loosen the neck of the hernia sac and return the contents of the hernia sac, otherwise it will cause necrosis of the intestinal tubes and other contents, which will lead to adverse consequences.
