A diabetic 38 years-old man has presented chills and fever with abdominal pain. Ct has showed a giant multiloculated liver abscess in central portion of the liver. He only presents renal insuficiency due sepsis, hemodialysis was done .Broad spectrum antibiotics was introduced without success. Drainage of multiple lesions is impossible. See that neither portal vein nor hepatic artery may be visualized . I am thinking in performing an open deroofing.
