Microvascular "supercharged" cervical colon: minimizing ischemia in esophageal reconstruction

Traditional colonic reconstruction of the esophagus is performed by cervical transposition of an isolated segment of colon with the vascular supply derived from one of the mesenteric colic vessels. The transposed cervical portion of the colon is farthest from the vascular supply and is at risk of ischemic injury. Despite notable risk of ischemic complications to the colonic neoesophagus, reports advocating a "supercharged" microvascular augmentation of the vascular supply to the cervical portion of the colon remain few in number. Herein, the ischemic complications associated with traditional transposition of the colon for esophageal reconstruction are reviewed, and avoidance by microvascular "supercharging" of the cervical colon is advocated under particular circumstances. The authors present a case of colonic interposition for esophageal replacement requiring a cervical microvascular anastomosis for survival of the transferred colon.
