title: Resection of giant liver adenoma in a 17-year-old adolescent boy using venovenous bypass, total hepatic vascular isolation, and in situ cooling.
abstract: Giant liver adenomas are rare pediatric tumors. Hepatocellular adenomas account for approximately 2% to 4% of all pediatric liver tumors. We present the case of a biopsy-proven 21 x 20.5 x 10.5-cm hepatocellular adenoma in a 17-year-old adolescent boy resected using venovenous bypass and total hepatic isolation. Hepatic adenomas of this size are historically treated with orthotopic liver transplantation. Resection of a massive centrally located giant liver adenoma using total hepatic vascular isolation and venovenous bypass with in situ hepatic cooling and is not previously reported. By combining these techniques, we were able to defer the risks of orthotopic liver transplantation and life-long immunosuppression for our patient. The patient's recovery was uncomplicated and hepatic regeneration was excellent. At 9 months' follow-up, the patient reported enjoying an athletic adolescent life-style with no evidence of recurrence.
