Primary Giant Splenic Echinococcal Cyst Treated by Laparoscopy.

Cystic echinococcosis (CE) is a zoonosis caused by the larval stage of the dog tapeworm Echinococcus granulosus. Liver and lungs are the most commonly affected organs whereas splenic infection is rarer and its primary involvement occurs in less than 2% of abdominal CE. We report a case of primary giant splenic hydatid cyst in a 75-year-old Peruvian woman that was laparoscopically removed without any complications, perioperative prophylactic chemotherapy with albendazole 400 mg twice a day 5 days before, and 7 days after the surgical procedure was administered, postoperative recovery was uneventful, and; at her 3-month follow-up the patient remains asymptomatic and an abdominal computed tomography scan demonstrated a cystic cavity of 15 cm diameter with no daughter vesicles, neither other abdominal organ involvement. This case is in line with the existing literature on laparoscopical treatment of splenic cystic hydatid disease, suggesting that laparoscopical treatment is a safe and effective approach for large splenic hydatid cysts to be preferred to open surgical techniques. © The American Society of Tropical Medicine and Hygiene.
