The most commonly encountered complications include wound infections, subphrenic collections and bile leaks from the cut liver surface. Stress ulceration of the stomach or duodenum is also not uncommon. Inadvertent bile duct damage has also been reported after major resection in children. The results of surgery for benign lesions are very good and usually depend simply on technical expertise. The results for malignant lesions, however, remain poor. Six series, including our own experience, reported in the last 5 years have shown an overall survival rate of 43% for patients whose tumours were resected for cure. It is difficult to compare results as authors differ in their presentation of results, but details of the series are listed in Table 7. There were no definite prognostic factors to be drawn from these series other than that children with the fibrolamellar variant of hepatocellular carcinoma fared better than those with other hepatomas. It is a sad fact that overall 56% of patients in these series presented with unresectable disease. Mahour et al. described seven patients with unresectable disease who were treated by either chemotherapy alone or in combination with radiotherapy, followed by 'second look' laparotomy and resection. Five of these patients were alive and disease-free for a minimum of 2.5 years after surgery. Thus it is necessary to adopt an aggressive approach to these tumours if one is to see any improvement on the overall figures.
