Presentación:
A 66-year-old man went to the emergency room for conjunctival and cutaneous jaundice associated with pruritus lasting 10 days, without abdominal pain or fever. In the analytical total bilirubin stands out: 9.79mg / dl, direct: 7.77 mg / dl, indirect 2.02 mg / dl, GGT 814U / L, FA 752 U / L, GOT 103 U / L, GPT 128 U / L and PCR 31.01mg / l. The computed tomography to which he was subjected showed the presence of several lesions compatible with hepatic hydatid cysts whose wall was discontinuous and showed a liquid-gas level inside. In addition, slight-moderate dilation of the main bile duct was observed, as well as several linear calcifications in its lumen compatible with hydatid membranes migrated by fistulization. Days later, the patient underwent ERCP with sphincterotomy, which confirmed the tomographic findings and resolved the biliary obstruction.
Discusión:
Although communication between the biliary tract and hepatic hydatid cysts occur in up to 80-90% of cases, the onset of symptoms only occurs in 13-37% of them1,2, in which the passage of the daughter vesicles or membranes of the cyst to biliary system, causes obstructive jaundice, cholangitis, or septicemia1. The diagnosis of rupture of the cyst to the bile duct is established by the discontinuity of the cyst contour and the presence of hydatid material in the biliary tree. The differential diagnosis of the presence of gas within the cyst includes fistulization to the bile duct, bronchial tree, or bacterial superinfection (mainly anaerobes)3. Although most of these fistulas could close spontaneously, endoscopic treatment with sphincterotomy is recommended to reduce morbidity, since it reduces biliary pressure and favors an early closure of said communication.
