Major hepatic resections for neoplasia in children.

In a consecutive series from 1968 to 1978, 11 hepatic resections encompassing at least two hepatic segments were carried out for neoplasia in pediatric patients varying in age from 7 days to 14 years. There were no operative deaths. These resections consisted of four right lobectomies, three extended right lobectomies, one right lobectomy with right nephrectomy and inferior vena caval resection, two left lobectomies, and one left extended lobectomy. Diagnoses were hepatoblastoma in six patients, Wilms' tumor invading the liver in two, hemangioendothelioma in two, and malignant mesenchymoma in one. Selective angiography and technetium Tc 99m sulfur colloid scintigraphy were important preoperative aids. Complications were infrequent and there were no major infections or biliary fistulas. There was one death eight months postoperatively due to recurrent hepatoblastoma. Vigorous hepatic regeneration occurred in all instances. Major hepatic resections are well tolerated in children and allow good subsequent development.
