Hemisplenectomy for giant splenic cysts in children.

To analyse the clinical features and outcome following surgery of giant splenic cysts in children, all patients presenting to a children's hospital over the years 1987-1996 were reviewed. Variables analysed included presenting symptoms, method of diagnosis, operative procedure, and complications. Six patients (aged 8-16 years) presented with abdominal pain or a large abdominal mass. Ultrasound examination demonstrated large (>5 cm) unilocular splenic cysts. Five of the six children underwent hemisplenectomy without complication or blood transfusion. The remaining patient had an infected cyst, for which total splenectomy was necessary because of major intraoperative haemorrhage. Hemisplenectomy is based on accurate dissection of the splenic hilum with clear knowledge of the intracapsular vascular anatomy of the spleen. Preoperative vaccination is recommended in the event that splenectomy is required. This retrospective review concludes that hemisplenectomy for splenic cysts is a safe procedure in children.
