The triangular ligament was taken down sharply, and the left lobe of the liver was retracted superolaterally using a fan retractor placed through the right lateral cannula.  The gastrohepatic ligament was then identified and incised in an avascular plane.  The dissection was carried anteromedially onto the phrenoesophageal membrane.  The phrenoesophageal membrane was divided on the anterior aspect of the hiatal orifice.  This incision was extended to the right to allow identification of the right crus.  Then along the inner side of the crus, the right esophageal wall was freed by dissecting the cleavage plane.
