Lymph node enlargement in the abdomen, according to the different causes of lymph node enlargement, clinically different treatment methods can be used. First, if the abdomen is traumatized, causing local soft tissue injury resulting in enlarged lymph nodes, can reduce the tissue exudation through local ice packs, twenty-four hours after the external application of bruise cream, oral pain and other drugs, to promote the absorption of local soft tissue. At this time, the enlarged lymph nodes can slowly subside, the prognosis is better. Second, the lymph nodes are enlarged due to serious infections in the abdominal cavity, such as acute necrotizing pancreatitis, digestive tract perforation, acute gangrenous cholecystitis, and so on. Through surgery to remove necrotic tissue and strengthen anti-infection treatment, the enlarged lymph nodes can subside by themselves. Third, if the abdominal tumor lesions, such as liver, stomach malignant tumors caused lymph node enlargement. The prognosis of this kind of patients is poor, even if the tumor is removed, it is easy to recur, endangering the patient’s life.
