Laparoscopic splenectomy for a giant splenic epidermoid cyst: report of a case

Abstract

The use of laparoscopic splenectomy has increased in recent years, primarily for patients with idiopathic thrombocytopenic purpura (ITP). We describe herein the first known case of a laparoscopic splenectomy to be performed in Japan for a patient with a giant splenic epidermoid cyst. A 26-year-old woman presented to our hospital with the major complaint of a feeling of abdominal fullness. Prior to surgery, an ultrasound-guided splenic cyst puncture was conducted for diagnostic purposes as well as to reduce the size of the cyst. The carbohydrate antigen 19-9 (CA 19-9) level was found to be elevated in the cystic contents and in the serum. Under laparoscopic guidance, the splenic vessels were ligated using a device for extracorporeal ligation, then divided. After the resected spleen had been placed in a retrieval bag, it was delivered out of the abdominal cavity without fragmentation. Following surgery, the patient's serum CA 19-9 level returned to normal. Splenic epidermoid cysts are most often encountered in young women, and laparoscopic surgery to remove cysts of this type is both minimally invasive and excellent from a cosmetic standpoint. Thus, laparoscopic surgery should be considered as the method of choice for the majority of patients diagnosed with a splenic epidermoid cyst.
