Traumatic splenic rupture is associated with generalized abdominal wall tenderness and muscle tonus on physical examination, most notably in the left upper abdomen. The high incidence of splenic trauma can be explained by the mechanism of its occurrence, as demonstrated by Gieseler’s experiments in 1965: not only direct trauma to the left side of the abdomen can cause splenic injury, but also indirect blows can cause splenic trauma. The tight union of the spleen with the gastric wall and the tight fixation of the surrounding ligaments restrict the sudden movement of the spleen, especially when the intra-abdominal pressure increases dramatically, the upper and lower poles of the spleen are very narrow, and the diaphragmatic surface is curved into an extremely convex form, while the base of the spleen is hyperextended, making the spleen very vulnerable to transection. In case of trauma, the pressure in the spleen and the pressure in the stomach are increased, while the increase in blood storage in the spleen leads to an increased possibility of injury. How to prevent and treat a hollow sound in the right waist when lying on the left side and a turbid sound in the left waist when lying on the right side? 1.Patients should be placed in a surgical ward for monitoring, with absolute bed rest for 2-3 weeks; 2.Fast food, continuous gastrointestinal decompression, and nutritional support; 3.Rapid blood volume replenishment to maintain water and electrolyte balance; 4.Close monitoring of hemoglobin, red blood cell pressure and urine volume; 5.Use of hemostatic agents and appropriate application of antibiotics. As the largest lymphoid organ in the body through blood circulation, the spleen plays an important role in the cellular and humoral immunity of the body. Studies have found that the risk of pulmonary infection, wound infection, thromboembolic lesions and even post-splenectomy fulminant infection can occur after splenectomy is significantly increased. With the progress of basic research, the function of self-hemostasis after splenic trauma provides a theoretical basis for non-surgical splenic preservation. The development of imaging can not only clarify the diagnosis, but also provide a basis for whether conservative treatment is possible. However, there are certain risks in the process of conservative treatment, so strict mastering of the indications for conservative treatment and strengthening the monitoring during treatment are the keys to success.
