title: [The laparoscopic spleen-preserving approach to splenic cysts: advantages and limitations].
abstract: BACKGROUND
  Due to the multiple functions of the spleen the preferred management of cystic non-parasitic lesions is nowadays laparoscopic partial splenectomy or decapsulation with preservation of the spleen. We have analysed our patients with non-parasitic cystic lesions and the current literature to weigh the benefits and complications of these methods in children and adults.
  
  
  METHODS
  Laparoscopic partial splenectomy was performed in three children with dysontogenetic cysts. Laparoscopic marsupialisation was performed in one child and in three adults.
  
  
  RESULTS
  Follow-up in the true cysts showed no recurrence in one patient and one residual cyst in the second. In the third patient, splenectomy was performed because there was not enough residual spleen to warrant preservation. In the group with post-traumatic cysts, no complications or recurrences were observed.
  
  
  CONCLUSIONS
  The laparoscopic spleen-preserving approach for the treatment of non-parasitic cysts is feasible, but challenging. The main problem is a recurrence rate of more than 20 %. The reason for recurrence remains uncertain: it is probably due to different operative strategies, the morphology of the cysts or the presence of residual cysts. The recurrence rate in post-traumatic cysts is low on the basis of our own experience and a literature survey.
  
  
  CONCLUSIONS
  The benefit of laparoscopic treatment in true non-parasitic splenic cysts has to be weighed against the rate of recurrence. A complete resection of the cysts should be attempted. In post-traumatic cysts, laparoscopy offers a good minimally invasive treatment option.
