（1）全腹紧张度增加：多见于胃肠道穿孔或脏器破裂所致的急性弥漫性腹膜炎

(1) Increased tension in the whole abdomen: more common in acute diffuse peritonitis (plate abdomen) caused by gastrointestinal perforation or organ rupture. <br>Tuberculous peritonitis and cancerous peritonitis, the abdominal wall is flexible and resistant to palpation, not easy to be crushed, and it is called a feeling of kneading. <br>(2) Increased local tension: caused by inflammation of intra-abdominal organs involving the peritoneum. <br>(3) Weakening of abdominal wall tension: seen in chronic wasting disease, severe dehydration, multiparous women, and the elderly and infirm. <br>2) Tenderness and rebound tenderness <br>(1) Tenderness: The location of tenderness is often the location of the lesion. Such as: gallbladder tenderness, appendix tenderness, etc. <br>(2) Rebound pain: more common in intra-abdominal organ lesions involving the adjacent peritoneum, seen in primary peritonitis.
