title: Hepatic lobectomies in children: experience of a center in the light of changing management of malignant liver tumors.
abstract: Hepatic resection is the main treatment modality for hepatic tumors in childhood. Advances in diagnostic technique, preoperative preparation, surgical technique, and postoperative management increased the success rate. The aim of this study is to report our experience in hepatic lobectomy, which is relatively rare procedure in childhood. Medical records of 25 patients who underwent hepatic lobectomy between January 1977 and June 2002 were reviewed retrospectively. Age, gender, diagnosis, physical examination findings, results of preoperative laboratory investigations, radiological examination, resectability criteria, preoperative biopsies, chemotherapies, radiotherapies, postoperative pathological results, incisions, operation technique, intraoperative transfusions, drains used, antibiotic prophylaxes, and intraoperative and postoperative complications were evaluated for all patients. Out of 25 patients with hepatic tumor seven patients with hepatoblastoma and four patients with hepatocellular carcinoma were given 5.7 +/- 0.3 cycles of chemotherapy before the operation. Right lobectomy (n = 12), left lobectomy (n = 5), extended left lobectomy (n = 4), and extended right lobectomy (n = 3) and right lobectomy with enucleation of two masses from left lobe (n = 1) were performed. Intraoperative blood transfusion of 30.7+/-6.0 ml/kg body weight was necessary. Pathological examination of resected tumors revealed hepatoblastoma (n=11), mesenchymal hamartoma (n = 5), hepatocellular carcinoma (n = 4), hemangioendothelioma (n=1), malignant mesenchymal tumor (n = 1), hemangioma (n = 1), cyst adenoma (n = 1), and metastasis of cellular mesoblastic nephroma (n = 1). Patients were observed in the intensive care unit for 3.4 +/- 0.3 days. Postoperative complications were sepsis (n = 1), disseminated intravascular coagulation (n = 2), fever (n = 3), jaundice (n = 3), intraabdominal abscess (n = 3), ileus (n = 2), and subdiaphragmatic abscess with pleural effusion (n = 1). Hepatic lobectomy is a major operation, which is feasible yielding curative results in children. Safe hepatic resections with acceptable blood loss can be performed by a technique relying on good anatomic dissection and surgical control.
