title: Laparoscopic or open splenectomy for hematologic disease: which approach is superior?
abstract: BACKGROUND
  This study was undertaken to compare safety, outcome, and costs of laparoscopic (LS) and open splenectomy (OS) for a variety of hematologic diseases.
  
  
  METHODS
  The records of 137 patients who underwent splenectomy (63 LS and 74 OS) at a large private teaching hospital between March 1991 and April 1996 were reviewed retrospectively. Diagnosis, age, gender, operative time, blood loss, splenic weight, time to resumption of oral diet, postoperative hospital stay, morbidity, mortality, and costs (direct and operative) were analyzed by multivariate statistical analysis.
  
  
  RESULTS
  Laparoscopic splenectomy patients had significantly shorter hospitalization and time to resumption of an oral diet (p < 0.01); although operative costs were higher, total direct costs were not. Idiopathic thrombocytopenic purpura patients had earlier resumption of an oral diet after LS, shorter postoperative stay, and comparable OR time. Five patients (7%) were converted, with outcomes similar to OS except for greater operative time and cost. Grade II complications occurred in three LS and four OS patients; Grade III in three OS patients; and Grade IV in two OS patients. There were two major complications of LS and eight of OS, with two deaths. Multivariate analysis showed that operative time and time to resumption of oral intake were significantly related to age, diagnosis, operative technique, and splenic weight. Duration of postoperative hospitalization was related to operative technique, splenic weight, and major complications. Costs (direct and operative) were related to age, splenic weight, and major complications, but not to operative technique.
  
  
  CONCLUSIONS
  LS results are influenced by splenic weight, disease, and age. Splenic weight appears to be the crucial determinant of operative time and length of hospitalization. LS is a superior treatment for patients with idiopathic thrombocytopenic purpura and patients with small spleens.
