Minilaparoscopy-guided spleen biopsy in systemic disease with splenomegaly of unknown origin.

subject

description

With the advent of a minimally invasive laparoscopy technique, the advantages of diagnostic laparoscopy are being rediscovered. We report here on four patients with systemic disease of unknown origin and splenomegaly, in whom minilaparoscopy-guided splenic biopsy yielded a definitive diagnosis. Four patients with unclear systemic disease were studied using diagnostic minilaparoscopy and guided spleen biopsy, after failure of diagnostic work-up. Minilaparoscopic spleen biopsy revealed the diagnosis of a B-cell non-Hodgkin's lymphoma in two cases. In one patient, who had a history of Still's disease, the spleen biopsy showed granulocytic infiltration in the spleen typical of an acute episode of Still's disease. One patient with a known immunodeficiency syndrome (stage C III) showed multiple hypodense lesions in the spleen. Biopsy allowed a diagnosis of mycobacterial infection, with identification of Mycobacterium tuberculosis. No major complications occurred in any of the four cases; post-biopsy bleeding was observed in three of the four, but was easily managed by argon plasma coagulation or application of fibrin glue, or both. We recommend the use of spleen biopsy as a diagnostic tool in splenopathy of unknown origin if previous diagnostic methods have failed to yield a definitive diagnosis.
