Clinical surgery-International Liver resection for benign liver tumors: indications and outcome

Background: The indications for intervention in cases of benign liver tumors include symptoms, suspi- cion of malignancy, or risk of malignant change. Methods: Eighty-four liver resections for benign tumors were performed in our hospital from June 1996 to December 2004. The patient records were reviewed retrospectively. Results: The study group (41 females, 43 males; average age, 41.4 10.5 y) included 46 cavernous hemangiomas, 27 focal nodular hyperplasias, 5 hepatic adenomas, and 6 liver cysts. The indications for resection were inability to rule out malignancy (50 (59.5%)), symptoms (33 (39.3%)), and others (1 (1.2%)). Postoperatively, 28 of the 33 patients had resolution of symptoms. Twenty-nine patients (34.5%) had chronic hepatitis B infection. Conclusions: Liver resection for benign liver tumor is safe, but indications for intervention must be evaluated carefully. The presence of chronic parenchymal liver disease does not increase morbidity in these patients. © 2007 Excerpta Medica Inc. All rights reserved.
