Laparoscopic decapsulation of congenital splenic cysts: a step forward in splenic preservation.
OBJECTIVE
The aim of this study was to evaluate the role of laparoscopic decapsulation in the management of congenital splenic cysts in children.


METHODS
Patients who presented over the last decade with congenital splenic cysts and were treated with laparoscopic decapsulation were reviewed retrospectively. The authors performed 4 procedures in 3 patients aged 10, 11 (and later 13), and 13 years. In all cases there was progressive enlargement of a single cyst, which lay in the upper pole of the spleen in 3 instances and in the lower pole in the fourth. Pneumoperitoneum was induced using the Veress needle technique, and 3 or 4 ports were utilized. Cysts were aspirated initially before marsupialization with excision of around two thirds of the cyst wall. Both endoshears and the harmonic scalpel were used with good hemostatic effect.


RESULTS
All patients had a good outcome with cyst resolution on long-term follow-up using serial ultrasound scanning. The first patient (in 1993) remained 3 days as an in patient postoperatively, and the others stayed overnight only. One patient had a new cyst near the first 30 months after the initial procedure. This again was dealt with laparoscopically, with patient discharge the following day. There were no complications in the short or long term. Histology in all cases confirmed a simple epithelial cyst. Median follow-up was 2 years (range, 6 months to 8 years).


CONCLUSIONS
Our experience shows that laparoscopic decapsulation is an effective means of managing congenital splenic cysts and that both harmonic scalpel and endoshears are satisfactory dissecting instruments. Extensive marsupialization is probably unnecessary in these larger cysts, because long-term follow-up has shown no increased risk of recurrence after leaving a significant proportion of the cyst wall behind. This approach helps avoid major surgery in these cases.
