On physical examination, traumatic splenic rupture may reveal generalized abdominal wall tenderness and muscle tonus, most notably in the left upper abdomen. The splenic turbid zone in the left quadrant of the rib cage is also often enlarged. If there is a large amount of blood accumulation in the abdomen, mobile turbid sounds can be found, but because there is often a clot around the spleen, the right lumbar region can be hollow when the patient is lying on the left side, but the left lumbar region often shows a fixed turbid sound when the patient is lying on the right side, which is called the Ballance sign. The diagnosis of right lumbar hollow sound when lying on the left side and left lumbar turbid sound when lying on the right side: In general, traumatic splenic rupture can be clinically classified into 3 types: 1. Immediate splenic rupture: that is, splenic rupture is usually referred to clinically, accounting for 80% to 90% of traumatic splenic rupture, which occurs immediately upon trauma with splenic rupture, intra-abdominal hemorrhage, hemorrhagic shock, and in severe cases, death can occur within a short period of time due to acute hemorrhage. Delayed (late) splenic rupture: It is a special type of traumatic splenic rupture, accounting for about 10% of closed spleen rupture, and there is an asymptomatic period (Baudet latency period) of more than 48h between trauma and splenic rupture and bleeding. 3, occult splenic rupture: there is only subperitoneal bleeding or slight laceration after splenic trauma, the symptoms are not obvious, and there is not even a clear history of trauma to be traced, so the diagnosis is not easy to be sure. It is diagnosed only in the presence of anemia, left upper abdominal mass, pseudocyst or rupture of the spleen, and intra-abdominal hemorrhage. This type is rare and occurs in less than 1% of closed splenic ruptures. Open injuries caused by sharp instruments are most often seen in wartime, where a bullet or shrapnel may injure the spleen regardless of where it enters the abdominal cavity. These open injuries are usually associated with other visceral injuries and require early exploratory abdominal surgery; preoperative confirmation of splenic rupture is difficult and not necessary. It should be noted that abdominal injuries with internal hemorrhage are more urgent than those with purely cavernous organ injuries. Closed splenic rupture is generally not difficult to diagnose based on a clear history of trauma to the left upper abdomen or left quadrant of the rib cage, local soft tissue contusions and rib fractures, and post-injury symptoms of peritoneal irritation and internal hemorrhage, especially if there are mobile turbid sounds in the abdomen.
