Background/Aims: In patients with advanced biliary malignancies, a chance of curability is obtained by only performing extended liver resection with concomitant pancreatoduodenectomy. This hepatopancreatoduodenectomy(HPD) is known to carry high risk of hepatic failure. We evaluated the effect of pancreatoduodenectomy on liver regeneration and the risk of hepatic failure in patients having undergone HPD to prevent complications associated with liver function.
Methods: Sixteen cases of HPD with extended liver resection were reviewed in the aspects of liver regeneration and hepatic failure. Twenty cases of extended right hepatectomy were selected as a control group(ERL group) for comparison of liver regeneration. Liver volumes were measured by computed tomogram volumetry.
Results: Resection rates of the liver and the pancreas in the HPD group were more than 51% and about 40%, respectively. Right portal vein embolization was performed in 66% of cases and all cases with obstructive jaundice underwent percutaneous biliary drainage. Rate of liver regeneration at postoperative 1 month in HPD group was 162%, and that of the ERL group was 169%, resulting in no statistical difference. There was no occurrence of hepatic failure in the HPD group.
Conclusions: Forty percent resection of pancreatic parenchyme following concomitant pancreatoduodenectomy may not compromise liver regeneration after extended liver resection. Complete external drainage of obstructive jaundice and preoperative portal vein embolization are recommended as preoperative procedures for patients undergoing extended liver resection with pancreatoduodenectomy.
