Intraoperative scintigraphic localization and laparoscopic excision of accessory splenic tissue

Abstract

The recent advent of laparoscopic splenectomy for the treatment of refractory idiopathic thrombocytopenic purpura (ITP) has been embraced by surgeons and hematologists in many institutions. However, the occurrence of accessory splenic tissue in a proportion of such splenectomies, either concurrently or later, raises the question of how to deal with this problem when it arises. We report that the laparoscopic approach, facilitated by lateral positioning, can be successfully used for the treatment of an accessory spleen causing recurrent ITP. The use of intraoperative nuclear imaging can greatly aid the localization and provide confirmation of complete excision of the nuclear focus, especially for a very small accessory spleen.
