The lengths of the orthotopic, retrosternal, and subcutaneous routes for esophageal replacement were measured in 20 patients at autopsy. The subcutaneous route is 1.8 cm longer than the retrosternal route, which is 1.9 cm longer than the orthotopic route. The difference between the subcutaneous and the orthotopic route is 3.7 cm.
