Echinococcosis extrahepatic biliary tract, in which the parasitic cysts are located in the wall or lumen hepaticocholedochus and gallbladder is rare.Depending on the nature of the defeat distinguish primary and secondary hydatid disease of the extrahepatic biliary tract.
In primary echinococcosis, encountered only 0,13-0,48% of the cases, cysts develop in the wall of the duct or gallbladder hexacanth from penetrating to the bloodstream.It is also possible lymphogenous path hexacanth penetration through post lymphatic vessels of the liver and gall bladder.
In secondary echinococcosis parasite enters the biliary tract of adjacent organs, mainly liver, resulting in the opening of parasitic cysts in the bile ducts and gall bladder.In such cases, the contents of the cyst, the cyst usually subsidiaries and fragments of shells, swim freely in the lumen of the gallbladder or hepaticocholedochus unlike cases of primary hydatid cyst when intimately fused with the walls of the latter.Perforation of hydatid cysts
Receipt cyst contents, often infected in the bile ducts can lead to blockage of the latter, which in turn is accompanied by the development of obstructive jaundice and septic cholangitis, which are extremely severe and life-threatening complications.
Echinococcosis gallbladder often occurs under the guise of chronic recurrent, and sometimes acute cholecystitis.In more rare cases, it can be mistaken for a bladder dropsy, empyema or slow tumor growth.In 10-12% of cases of hydatid disease of the gallbladder combined with cholelithiasis.The latter may develop secondarily on the basis of long-term chronic inflammation of the wall of the jet of the gallbladder, in contact with parasitic cysts.At the break of an infected cyst in the gallbladder may experience rough clinical picture with sharp pain in the right upper quadrant, chills, fever, nausea, vomiting, urticaria often.All this is extremely difficult to correct diagnosis.In most cases, patients operate under a different diagnosis, which, however, is not a serious mistake, because the treatment of echinococcosis of the extrahepatic biliary tract can only be surgical, and in order to avoid complications as much as possible earlier.
nature of surgery may vary in each case, but in general, depends on the location of the lesion, complications and patient's general condition.Surgery should always be aimed at the removal of hydatid cysts and restoring patency of the bile ducts.When echinococcosis gallbladder cholecystectomy satisfies these requirements, and with the defeat of hepaticocholedochus - opening and drainage ducts.In secondary lesions of the extrahepatic biliary tract is necessary to open and empty communicating with them hydatid cyst.In some cases, this is enough to pull the entire biliary drainage systems and thus achieve a rapid recovery.It must be remembered about the possibility of multiple lesions and carefully examine the liver, not to leave unnoticed cysts.

Secondary hydatid disease of the biliary tract is unfavorable from the point of view of the forecast, as the majority of such patients operate even in the presence of severe complications: septic angioholitah, obstructive jaundice., liver failure, severe intoxication, etc. It causes high mortality after such operations (25-47%) and frequent postoperative complications - bile and purulent fistulas, peritonitis, cardiovascular failure, pneumonia.Improved results of operations is possible only with timely intervention.
