Extended left hepatectomy associated with resection of the vena cava and suprahepatic veins by in situ perfusion to treat intrahepatic cholangiocarcinoma.

Cholangiocarcinoma is a heterogeneous group of aggressive tumors that correspond to the second most common primary liver tumor. They can be classified according to their anatomical position concerning the biliary tree, and each subtype demonstrates different behavior and treatment. A 38-year-old male patient presenting solely right lumbar pain was diagnosed with a 7 cm hepatic tumor involving segments I, Iva, and VIII associated with involvement of the hepatic veins. He underwent a bloc resection of hepatic segments I, II, III, IV, partial V, partial VII, and VIII; right, middle, and left hepatic veins; and inferior vena cava segment, with perfusion of the remaining liver in situ with a preservation solution. As the patient had a large accessory inferior right hepatic vein draining the remaining liver, no reimplantation of hepatic veins was necessary. He remained clinically stable in outpatient follow-up, with excellent performance status-current survival of 2 years 6 months after surgical treatment.

Hepatoportoenterostomy surgery technique.

Biliary atresia (BA) is a pathology that causes jaundice in children because of an obstruction of the obliterated biliary tract. Despite being considered a rare disease, the incidence can reach 1/2400 live births in the Pacific region. The etiology is unknown. If untreated, it will lead to cirrhosis and death. Early operation (within 60 days after birth) is the most important prognostic factor. The objective of this article is to present the technical description step by step of a hepatoportoenterostomy operation in a female 61 days of age with BA.
