Diaphragmatic resection in association with right hepatectomy.

Ten cases of combined diaphragmatic and hepatic resection for tumours involving both structures are described. A complete work-up, including ultrasonography and computed tomography, usually can predict potential direct spread to the diaphragm. Up to 50% of the diaphragm can be excised and reconstructed without the need for prosthetic mesh or tissue transfer. Diaphragmatic resection does not appear to cause long-term postoperative morbidity. Diaphragmatic invasion by primary or secondary tumours does not preclude resection for cure. Pulmonary function studies are not necessary if there is no serious pre-existing lung disease.
