Splenectomy versus spleen-preserving surgery for splenic echinococcosis.

Background/aims: The spleen is the third most common location of hydatid disease after liver and lung. The aim of this study was to analyse the long-term outcome of surgical treatment of patients with splenic echinococcosis comparing splenectomy with spleen-preserving surgery.

Methods: During a period of 25 years (1976-2001), 19 (5.4%) patients with splenic echinococcosis were treated in our department out of 349 patients with abdominal hydatid disease. In 16 patients the spleen was the only organ involved, while in 3 patients the liver was also affected.

Results: Eleven patients had splenectomy and in the other 8 the spleen was preserved: enucleation (n = 4), partial cystectomy and omentoplasty (n = 2) and cystojejunal Roux-en-Y anastomosis (n = 2). One (6%) patient died in the early postoperative period and 5 (29%) patients had postoperative complications. There was no significant difference between the splenectomy and spleen-preserving groups concerning median hospital stay and postoperative complication rate. The median follow-up in 15 patients was 52 (range 6-300) months. Two patients (13%) developed recurrence of the disease requiring re-operation at 2 and 3 years, respectively. Recurrence occurred in 1 (12%) patient in the splenectomy group and in 1 (14%) out of 7 patients in the spleen-preserving group.

Conclusion: In the present series it was possible to preserve the spleen in 8 (42%) of 19 patients, without significant increase of recurrent echinococcosis.
