Hydatid Disease — An Overview

ABSTRACT

Human Hydatid Disease is a growing menace, a parasitic disease present in many countries all over the globe (more than 1 million people are affected throughout the World annually). Tape-worm is the main causative organism.In humans it is prevalent in two forms – Cystic Echinococcosis (CE) [caused by Echinococcus granulosus] and Alveolar Echinococcosis (AE)[caused by Echinococcus multilocularis]. Humans are the accidental intermediate host; they are being affected by drinking water or eating food contaminated with parasite eggs or by direct contact with infected animal hosts like dogs. In humans, the most commonly affected organ is Liver followed by the Lungs. The main investigational tool is Ultrasonography but Computed Tomography (CT) and serological tests are also helpful in the diagnosis of Liver Hydatid Cysts (LHC). Although PAIR technique is the most important modality of therapy along with medical treatment, surgery has got a great role in the management of the entire spectrum of the disease. Nowadays, various Laparoscopic techniques have been safely used to improve the morbidity and mortality associated with the surgical management of the disease, and is the only other therapeutic option used all over the World. Prevention programme includes, public awareness and Education, dog deworming and slaughterhouse hygiene.
