Background: Laparoscopic splenectomy is an effective treatment for idiopathic thrombocytopenic purpura (ITP) and hemolytic anemia that has a remission rate of 80-90%. In some patients in whom the disease persists or recurs, a diagnosis of accessory spleen is made. The long-term efficacy of laparoscopic accessory splenectomy is unknown.

Methods: Patients who underwent laparoscopic accessory splenectomy were followed in the outpatient clinic. The perioperative course, blood counts, and need for medical therapy to maintain a normal count were recorded.

Results: Eight patients underwent laparoscopic accessory splenectomy. All procedures were completed laparoscopically, and all patients were discharged on the 1st postoperative day. Patients were available for a follow-up period of 15 months range, (3-27). None of the ITP patients achieved a complete remission. Two of them had a partial remission, and five ITP patients are now being treated with chronic corticosteroids to maintain a platelet count of >100,000/ml.

Conclusions: Laparoscopic accessory splenectomy is associated with a low rate of morbidity and a short hospital stay. Despite its success in removing all residual splenic tissue, most patients will probably not enjoy a complete remission.
