Symptoms of vomiting accompanied by umbilical pain in children may be caused by bacterial or viral infections, and should be promptly treated with medical examination and treatment.

Once diagnosed, emergency surgery should be performed. Preoperative preparation includes gastrostomy tube decompression, correcting electrolyte balance, enhancing blood transfusion, and administering antibiotics and vitamin K. For children with severe abdominal distension, abdominal puncture decompression can be performed to relieve breathing difficulties.
