title: Laparoscopic splenectomy: outcome and efficacy in 103 consecutive patients.
abstract: OBJECTIVE
  To study the safety and efficacy of laparoscopic splenectomy (LS) in patients with predominantly benign hematologic disorders.
  
  
  BACKGROUND
  The technical feasibility of LS has been recently established. However, data regarding the efficacy of the procedure in a large cohort of patients are scarce.
  
  
  METHODS
  One hundred three consecutive patients underwent LS between June 1992 and October 1997. Data were collected prospectively on all patients.
  
  
  RESULTS
  Indications were idiopathic thrombocytopenic purpura (ITP), hereditary spherocytosis, autoimmune hemolytic anemia, thrombotic thrombocytopenic purpura, and others. Mean spleen size was 14 cm and mean weight was 263 g. Accessory spleens were found in 12 patients with ITP and in 5 patients without ITP. There were no deaths. Complications occurred in six patients, one requiring a second procedure for small bowel obstruction. Six patients received transfusions, and four procedures were converted to open splenectomy for bleeding. Mean surgical time was 161 minutes and was greater in the first 10 cases than the last 10. Mean postsurgical stay was 2.5 days. Thrombocytopenia resolved after surgery in 84% of patients with ITP, and hematocrit levels increased significantly in 70% of patients with chronic hemolytic anemias. A positive response was noted in 92% of patients with hereditary spherocytosis, without relapse for the duration of the observation. ITP relapsed in four patients during follow-up, three within 12 months.
  
  
  CONCLUSIONS
  LS can be performed safely and effectively in a teaching institution. Rigorous technique will minimize capsular fractures, reducing the risk of splenosis. Accessory spleens can be successfully localized, thus improving response and limiting recurrence of ITP. LS should become the technique of choice for treatment of intractable benign hematologic disease.
