Splenic cysts are rare in pediatric surgery. Congenital epidermoid cysts are exceptional representing only 2.5% of all splenic cysts in childhood. Nowadays, considering the short- and long-term complications of splenectomy in children, the management of epidermoid cyst consists of partial splenectomy or decapsulation of the cystic wall. To our knowledge, the case reported in this article describes the first successful laparoscopic decapsulation of an epidermoid splenic cyst in an 10-year-old child using the UltraCision LaparoSonic Coagulating Shears (LCS). Follow-up at six months confirms no recurrence. Laparoscopic splenic decapsulation provides minimal access and small surgical trauma for treating the cyst while preserving splenic function. The use of UltraCision LCS makes the laparoscopy safely, expeditiously, with minimal blood loss and short hospital stay.
