[Partial splenectomy in non-traumatic benign lesions of the spleen].

Partial splenectomy was performed in a patient with cystic lymphangioma and two patients with splenic pseudo-cysts, one of traumatic origin and the other necrotic following infarct. Anatomical features on which this operation is based, together with the technique employed, are exposed and the criteria of efficacy examined. Partial splenectomy was performed to reduce splenomegaly complicated with hypersplenism, and is also applicable for exeresis of cystic and pseudo-cystic splenic lesions. These indications are worthy of more extensive application in young adults.
