The surgeon’s goal is to split the diaphragm such that the liver and spleen can be mobilized partially or entirely into the pleural cavity when the patient is in the Trendel- enburg position. The diaphragmatic incision should be a semicircle aiming to- ward the great vessels and the crus of the diaphragm. FIGS. 1-14 AND 1-15.
