The use of endoprostheses in biliary fistula of hydatid cyst.

摘要: Hydatid disease is a common medical problem in some areas of the world. In fact, it main zoonosis affecting human population southern Chile.1,2 The incidence this country has been approximately 600 to 800 new cases per year. Among patients harboring disease, liver most commonly affected organ with an infestation rate 60% 74%. Cyst rupture into biliary tree complication, right hepatic duct more involved (55% 60%).3 Communications are usually small, occurring as result tears between cyst wall and radicles. Large involving bile ducts less frequent (7% 9%). Obstructive jaundice cholangitis occur when daughter cysts fragmented membranes obstruct (5% 10%).4-6 Biliary fistula develops after surgical drainage intracystic pressure decreases.7,8 involvement not easy detect. CT US generally fail show involvement. Intravenous cholangiography rarely shows well-defined image tree, percutaneous transhepatic contraindicated because chance causing intraabdominal spread echinococcal contents subsequent anaphylactic shock.9,10 Because relative high morbidity mortality rates associated therapy, nonoperative methods treatment for fistulas have developed. use ERCP considered effective detecting from cyst, also provides approach therapy.11,12 We report here our experience management four hydatid communicated using stent insertion.
