Extended subcostal hinge incision for right hepatic lobectomy.

The safe performance of a right hepatic lobectomy requires adequate exposure of the hepatic veins and of the suprahepatic vena cava. An extended subcostal or midline incision is commonly used to provide exposure for this operation. The technique for an extended subcostal incision that uses the natural hinge mechanism of the rib cage to provide exposure to the right upper quadrant is described. This approach provides adequate exposure during a difficult hepatectomy, avoiding the need for a thoracotomy or sternotomy.
