There are a variety of anatomoclinical forms of hepatic echinococcosis. This has led to finding and applying a number of surgical procedures which have the same aim, namely the reduction or elimination of the pericystic cavity. Besides, solving the residual pericystic cavity after the elimination of the parasite represents the main problem of the surgical treatment. The postoperative complications of the hydatid cyst are caused by the failure to adapt the surgical procedures to the morphological characteristics of the pericystic cavity.
In the Romanian medical literature, the surgeries performed for the hepatic hydatid cyst are divided into the so-called conservative surgeries, which abandon the pericystic cavity or resect a part of the pericyst, and the so-called radical surgeries, which completely remove the pericystic cavity by sacrificing a smaller or greater area of the parenchyma of the liver.
