Surgical management of cystic lesions in the liver.

BACKGROUND: Liver cysts are common, occurring in up to 5% of the population. For many types of cysts, a variety of different treatment options exist and the preferred management is unclear.
METHODS: A PubMed and Medline literature review was undertaken and articles pertaining to the diagnosis and management of cystic lesions within the liver were retrieved.
RESULTS: Therapy for symptomatic cysts may incorporate aspiration with sclerotherapy or de-roofing. Polycystic liver disease presents a unique management problem because of the high morbidity and mortality rates from intervention and high rates of recurrence. Careful patient counselling and assessment of symptom index is essential before embarking on any treatment. New medical treatments may ameliorate symptoms. Acquired cystic lesions in the liver require a thorough work-up to fully characterize the abnormality and direct appropriate treatment. Hydatid cysts are best treated by chemotherapy, followed by some form of surgical intervention (either aspiration and sclerotherapy or surgery). Liver abscesses can be effectively treated by aspiration or drainage.
CONCLUSION: All patients with cystic lesions in the liver require discussion at multidisciplinary meetings to confirm the diagnosis and determine the most appropriate method of treatment.
