BACKGROUND:

Hydatid disease, a parasitic infestation caused by Echinococcus granulosus larvae, is an infectious disease endemic in different areas, such as India, Australia, and South America. The liver is well known as the organ most commonly affected by hydatid disease and may present a wide variety of complications such as hepatothoracic hydatid transit, cyst superinfection, intra-abdominal dissemination, and communication of the biliary cyst with extravasation of parasitic material into the bile duct, also called cholangiohydatidosis. Humans are considered an intermediate host, exposed to these larvae by hand-to-mouth contamination of the feces of infected dogs.

AIM:

This study aimed to highlight the role of endoscopic retrograde cholangiopancreatography in patients with acute cholangitis secondary to cholangiohydatidosis.

METHODS:

Considering the imaging findings in a 36-year-old female patient with computed tomography and magnetic resonance imaging showing a complex cystic lesion in liver segment VI, with multiple internal vesicles and a wall defect cyst that communicates with the intrahepatic biliary tree, endoscopic biliary drainage was performed by endoscopic retrograde cholangiopancreatography with papillotomy, leading to the discharge of multiple obstructive cysts and hydatid sand from the main bile duct.

RESULTS:

Clinical and laboratory findings improved after drainage, with hospital discharge under oral antiparasitic treatment before complete surgical resection of the hepatic hydatid cyst.

CONCLUSIONS:

Endoscopic retrograde cholangiopancreatography is a safe and useful method for the treatment of biliary complications of hepatic hydatid disease and should be considered the first-line procedure for biliary drainage in cases of cholangiohydatid disease involving secondary acute cholangitis.

ABSTRACT - BACKGROUND:

Hydatidosis is a rare and endemic parasitic disease in Brazil that causes the proliferation of cysts mainly in the liver, leading to many complications, such as compression of vessels and biliary ducts, liver failure, portal hypertension, and cirrhosis. The treatment of choice is the resection of the lesions combined with albendazole therapy. This disease is a rare indication for liver transplantation, a feasible treatment option in more advanced stages.

AIM:

The purpose of this study was to describe two cases of patients from northern Brazil who underwent liver transplantation due to hepatic hydatidosis.

METHODS:

This is a retrospective study with data collected from medical records.

RESULTS:

Case 1: A 51-year-old female patient presented pain in the right hypochondriac, dyspepsia, consumptive syndrome, and obstructive jaundice, with a previous diagnosis of Caroli’s disease with no possibility of surgical resection and a MELD score of 24. She underwent liver transplantation, and the anatomopathological result demonstrated hydatidosis. Case 2: A 52-year-old female patient presented multiple episodes of cholangitis in 30 years, with three liver resections and clinical treatment with albendazole for hydatidosis. She underwent liver transplantation due to recurrent cholangitis with a MELD score of 20. Both patients underwent post-transplant clinical therapy with albendazole, had good outcomes, and remain in follow-up without complications after 5 and 96 months, respectively.

CONCLUSION:

The patients benefited from the procedure and have a good prognosis due to the absence of metastasis, early reintroduction of antiparasitic drugs, and continuous follow-up.
