Internal mammary blood supply for ileo-colon interposition in esophagogastroplasty: a case report

Abstract

We report on a clinical case where microsurgical techniques successfully supported traditional surgery in a wide reconstruction between the oropharynx and small bowel. Several years ago, the patient sustained a severe corrosive injury of the upper digestive tract with subsequent esophageal stricture and stiffening; at that time, an emergency gastrectomy was performed. In this case, the restoration of the defect could not rely on the classic colonic interposition. During the operation the ileo-colic flap, well-fitted for tension-free reconstruction, revealed the foreseen inadequacy of its vascularization based on the sole middle colic vascular pedicle. The blood supply to its proximal part was then increased by microanastomosis between the right internal mammary and ileo-colic vessels. The revascularization ensured the viability of the interposed tissue. Oral intake resumed after 3 weeks; nowadays the patient is able to maintain her ideal weight with adequate nutrition.
