To determine whether the appendiceal stump is normal or not, usually the clinical manifestations can be initially judged, and then need to follow the doctor’s instructions to do blood routine, imaging tests such as abdominal ct, ultrasound and barium enema examination to clearly determine. 1. Clinical manifestations: Most patients with appendicitis residual strain have the same symptoms as those of first-time appendicitis, which may include right lower abdominal pain, accompanied by loss of appetite, nausea, vomiting and elevated body temperature. 2. Blood test: The blood test of appendicitis residual strain may show that the white blood cell count is larger than normal and the proportion of neutrophils is increased. 3. Abdominal ct and ultrasound: patients with appendicitis residual strain may show occlusion of the appendiceal lumen, edema, effusion or obvious dilatation. 4. Barium enema examination: Barium enema examination can help to diagnose appendicitis residual, which can be seen as irregular filling of the appendix, excessive length of the stump, stiffness of the appendix and poor peristalsis. It is recommended that patients with the above clinical symptoms should go to the hospital in time to do relevant examinations, so that doctors can diagnose whether appendicitis is normal or not, and avoid misdiagnosis.
