title: Laparoscopic splenectomy for idiopathic thrombocytopenic purpura (ITP).
abstract: BACKGROUND
  Although the short-term benefits of laparoscopic splenectomy (LS) have been well documented, long-term follow-up data of patients who have undergone LS for ITP are scarce. We report our long-term follow-up data in patients who underwent LS for idiopathic thrombocytopenic purpura (ITP).
  
  
  METHODS
  Data were obtained from a prospectively collected computer database of 52 patients who underwent LS between October 1992 and December 2000 for medically refractory ITP. Patients and their referring hematologist were contacted, and follow-up information was obtained for 45 patients.
  
  
  RESULTS
  Fifty-two patients (27 women and 25 men) underwent LS for ITP. Median operative time was 160 min (range, 70-335); and median blood loss was 100 cc (range, 20-1500). There were seven cases of intraoperative hemorrhage (13.7%), resulting in one conversion. A second case was converted due to inadequate working space in a patient with a 26-cm spleen. Accessory spleens were found in 17 patients (32.7%). Postoperative complications occurred in three patients (5.9%). There were no deaths. Median length of hospital stay was 2 days (range, 1-12). Follow-up data were obtained in 45 patients (86.5%), with a median follow-up of 51 months. Six patients did not respond to surgery initially, and another two patients developed recurrent disease, for a remission rate of 82.2%. Nine patients underwent a damaged red blood cell scan. This group included the two patients who suffered recurrences. A positive scan was obtained in three patients (33%), one of whom was a patient with recurrent disease. This patient underwent an uneventful laparoscopic excision of residual splenic tissue but continues to require intermittent steroids to maintain platelet counts. The two other patients with a positive scan remain in remission.
  
  
  CONCLUSIONS
  Laparoscopic splenectomy for ITP is safe and associated with low morbidity and a short hospital stay. Long-term follow-up showed that remission rates of ITP following LS are comparable to those reported in the literature on open surgery.
