Early symptoms of bowel perforation may include abdominal pain, abdominal muscle tension, and an abdominal mass. In the early stages of intestinal perforation, patients typically experience abdominal pain near the location of the perforation. After the perforation, the contents of the bowel leak out of the perforation into the abdominal cavity, causing signs of peritoneal irritation, and the patient may experience severe abdominal pain and abdominal muscle tension in the form of a plate. As a result of abdominal infection, it can lead to chills, high fever and other symptoms, and on examination the patient has signs of abdominal pressure, rebound pain and loss of bowel sounds. In a small number of patients, the perforation is chronic, the process of perforation formation is slow, wrapped by the surrounding organs or omentum, and symptoms such as abdominal pain and abdominal mass may occur, and symptoms of peritonitis may be atypical. When intestinal perforation is found, it is recommended that patients seek timely medical examination and treatment to avoid further development of perforation enlargement, causing serious complications such as peritonitis, and even endangering patients’ lives. So once there are symptoms of intestinal perforation, it should not be taken lightly.
