[Laparoscopic resection of intraoperatively diagnosed parasitic cyst of the liver with the use of harmonic scalpel].

Echinococcus granulosus is one of the most important parasitic infections in the Mediterranean countries, it presents in the form of cystic lesions of the liver. During their development the cysts may cause various symptoms due to compression. Rupture of the cysts may lead to anaphylactoid reactions and/or to acute abdomen. We operated on a patient with symptoms of cholelithiasis and cholecystitis; she underwent laparoscopic cholecystectomy, during which a cystic tumour in the liver was accidentally detected. Successful laparoscopic pericystectomy was performed with Harmonic Scalpel. We are sure that laparoscopic resection of hydatid cysts is a safe option for a number of patients in the treatment of parasitic cysts of the liver.
