Pharyngoesophageal bypass using a free jejunal graft for corrosive stricture--a case report.

The management of corrosive strictures of the esophagus involving the pharynx and/or larynx continues to be a challenge to surgeons. This paper presents a case of a corrosive stricture extending from the hypopharynx to the cervical esophagus associated with complete obstruction of the larynx, which was successfully treated by pharyngoesophageal bypass using a free jejunal graft. Postoperative recovery was smooth without any complications, and swallowing was restored. Three months after the bypass operation, the patient underwent laryngoplasty. Although aspiration occurred immediately after the laryngoplasty, six months later she was again able to tolerate the oral intake of semisolid food without any need for supplementary nutritional support. Reconstruction of a short segment of the pharyngoesophageal stricture by a free jejunal graft restores almost normal swallowing provided that dilatation of the lower esophagus is achieved.
