Extended left hepatectomy (left hepatic trisegmentectomy) in childhood

Background/Purpose: Extended left hepatectomy, also referred to as left hepatic trisegmentectomy, in which segments II, III, IV, V, and VIII are excised, is rarely performed in children. Experience with 7 such resections is reported to describe the anatomy, technique, indications, and outcomes of the operation. Methods: The medical records of all pediatric patients treated at our institution over the last 15 years who underwent extended left hepatectomy were reviewed. Demographic information as well as operative, pathological, and follow-up data were analyzed. Results: Seven patients underwent extended left hepatectomy over this period. There were 5 boys and 2 girls ranging in age between 4 months and 9 years with a median age of 3.2 years. Follow-up ranged from 8 months to 5 years with a median of 3.5 years. Diagnoses included hepatoblastoma (HB, n = 3), focal nodular hyperplasia (FNH, n = 1), leiomyosarcoma (LMS, n = 1), hepatocellular carcinoma (HCC, n = 1), and metastatic neuroblastoma (NB, n = 1). All surgical margins were grossly negative. Median operative blood loss was 13 mL/kg (range, 5 to 32 mL/kg), and mean hospital stay was 9 days (range, 7 to 12 days). No major intra- or postoperative complications were encountered, and there was no perioperative mortality. The 3 HE patients, 1 FNH patient, 1 LMS patient, and 1 NE patient are without evidence of disease, whereas the 1 child with HCC died of recurrent and distant disease. The 6 surviving children have normal hepatic function. Conclusion: Although technically challenging a nd rarely performed, extended resection of the left hepatic lobe is feasible in children and can yield curative results with minimal morbidity.
