A novel method for treatment of pseudomonas pyogenic hepatic abscess complicating an echinococcal cyst by irrigation with acetic acid. A case report and literature review.

Unlabelled: Hepatic hydatid cysts can be complicated by pyogenic abscesses. We report a case of hepatic hydatid cysts presenting to Sultan Qaboos University Hospital (SQUH) on 29 June 2010 complicated by secondary infection with fully sensitive . The infection persisted despite standard treatment (drainage and systemic antibiotics) and was eventually cured with a novel method using acetic acid.

Methods: Instillation of acetic acid (in the form of white vinegar) into the hepatic abscess through the pig tail drainage tube.

Results: The administration of acetic acid (6%) in the form of white vinegar was well tolerated and safe to the patient and resulted in complete clinical and radiographic resolution of the hepatic abscess.

Conclusion: Acetic acid (vinegar) irrigation can be used to clear a refractory pyogenic hepatic abscess due to infection.
