Successful laparoscopic-assisted partial splenectomy and splenopexy with umbilical approach to wandering spleen with an enlarged cyst in a pediatric patient.

A 10-year-old girl with a wandering spleen with an enlarged cyst was successfully treated by laparoscopic-assisted partial splenectomy and splenopexy. The patient visited our hospital with a complaint of a lower abdominal mass. Abdominal computed tomography showed malposition of the spleen and the presence of a 10 cm diameter splenic cyst (SC) in the lower pole. In surgery, the navel was opened with an inverted Y-shaped incision. The SC was punctured and aspirated the contents of the cyst, the migrating spleen was pulled out of navel and the partial splenectomy was done. The residual spleen was laparoscopically fixed by creating an extraperitoneal pocket. Pathologically, the cyst was covered with a vitrified fibrotic capsule and was diagnosed as a pseudocyst. We considered it a traumatic cyst. The postoperative course was uneventful. This minimally invasive laparoscopic procedure was feasible and effective for treating wandering spleen with a large SC in a pediatric patient.
