Benign liver tumors in children: outcomes after resection.

<bold>Purpose: </bold>Benign liver tumors in children are rare and data regarding the surgical outcomes are deficient. We reviewed our experience in the management of these tumors particularly the extent, safety, and effectiveness of surgical resection.<bold>Methods: </bold>Between March 2005 and March 2014, 10/90 liver resections were performed for benign liver tumors. Three other patients received conservative treatment. Demographic characteristics, operative management, morbidity, and mortality were analyzed.<bold>Results: </bold>The median age of the patients was 12 months. The distribution of pathology was infantile hepatic hemangioendothelioma/hemangioma (n = 7), mesenchymal hamartoma (n = 4), adenoma (n = 1) and focal nodular hyperplasia (n = 1). Median tumor size was 12.25 cm (range 3.5-21 cm) with a median tumor volume of 576.64 cm(3) (range 13.9-1822.64 cm(3)). Non-anatomic resection was performed in 6/10 patients and the median blood loss was 100 ml (range 10-850 ml). Median length of hospital stay was 7 days (range 5-9 days). There were no mortality, none of the patients had a local recurrence, and all are alive at a median follow-up of 33 months.<bold>Conclusions: </bold>Two-third patients with benign liver tumors were managed with surgical excision, which comprised 11% of our resectional practice. Non-anatomical resection whenever feasible can be performed safely and does not compromise the oncological outcomes. [ABSTRACT FROM AUTHOR]
