Closed abdominal injuries are common in production, traffic and life accidents. The prognosis of a patient is determined by the presence or absence of visceral injury, often accompanied by other parts of the injury, such as brain trauma, chest trauma, and fractures, which mask the history and signs, making the diagnosis difficult to determine; and because of some minor injuries, There may be abdominal organ damage. Therefore, the closed injury of the abdomen must be closely observed, repeatedly checked, and properly handled to avoid delay in diagnosis and treatment.
