Changing concepts in the management of liver hydatid disease.

Hydatid disease is a rare entity primarily affecting the population of developing countries. The parasite shuttles between the liver and lungs. but almost any organ can be invaded, forming cysts. Septation and calcification of the cysts with a high antibody titre in the patient's serum confirm the diagnosis, although more sophisticated tests have been applied recently. Surgery constitutes the primary treatment, with a variety of techniques based on the principles of eradication and elimination of recurrence by means of spillage avoidance. Minimally invasive techniques and percutaneous drainage of the cysts are now feasible because of progress in the field. The aim of this review is to collect the experience from three different institutions and to provide practical guidelines for diagnostic and therapeutic strategies.
