Partial laparoscopic decapsulation of congenital splenic cysts. A medium-term evaluation proves the efficiency in children.
BACKGROUND
In children, laparoscopic decapsulation of large congenital splenic cysts has occasionally been advocated, but substantial series focusing on its long-term success are still lacking. We report the follow-up experiences from two pediatric surgical centers.


METHODS
The decision to proceed to surgery was based on patient symptoms and cyst size (>4 cm and/or progression), after strictly exclusion of a parasitic cause (by serology and CT scan). With the use of three ports (5-10-mm) and a Harmonic Scalpel, the epithelial portion of the cyst was radically excised. The remaining hilar epithelium was coagulated carefully. After discharge, the children were examined regularly by ultrasound to detect recurrences.


RESULTS
From 1998 until 2002, eight children (mean age, 11.1 years; range, 3.1-16.4) were treated for cysts ranging from 4 to 15 cm in diameter. All procedures were completed without significant intraoperative complications (no major bleeding, no conversions). The mean operating time was 75 min (range, 56-184). Postoperatively, one child developed a cystic remnant (2 cm), which remained unchanged during 30 months of observation. After a mean follow-up of 2.2 years (range, 13-38 months), none of the patients showed any evidence of recurrent growth, and all of them had healthy splenic remnants.


CONCLUSIONS
Partial laparoscopic decapsulation is an advantageous approach to large splenic cysts in children, because it is effective, preserves splenic tissue, and provides good medium-term results.
