Hand-assisted laparoscopic splenectomy for a huge splenic cyst: operative technique and case report

We report the case of a huge splenic cyst that was successfully treated by hand-assisted laparoscopic splenectomy. A 17-year-old girl with a chief complaint of left-sided abdominal pain was admitted to our department for investigation of a splenic tumor. Ultrasonography, computed tomography, and magnetic resonance imaging revealed a huge cystic lesion in the spleen measuring approximately 10 cm in diameter. Hand-assisted laparoscopic splenectomy was safely performed to diagnose and treat the splenic tumor. The histologic diagnosis was an epithelial cyst of the spleen with no atypical cells in the cyst wall. Hand-assisted laparoscopic splenectomy may be a good method of managing a huge splenic cyst that becomes symptomatic and potentially life-threatening through enlargement, rupture, and secondary infection.
