Figure 13a. Jejunal interposition (pharyngojejunoesophagostomy with jejunal free graft) in a 51-year-old man with SCC of the cervical esophagus. (a) Pre-operative CT scan (5-mm section thickness) obtained at the level of the cricoid cartilage shows a mass (arrow) in the cervical esophagus. (b) Postoperative barium esophagogram shows anastomoses at the pharyngojejunostomy (arrowhead) and jejunoesophagostomy (arrow) sites. Note the normal valvular conniventus of the jejunum.
