Tubed Anterolateral Thigh Free Flap for Pharyngoesophageal Reconstruction

Caustic ingestions can severely injure the upper and lower aerodigestive tract, resulting in detrimental mucosal changes both acutely and chronically. Injuries are most severe following alkaline ingestion. Esophagectomy is often recommended in patients with high-grade esophageal injuries to mitigate the risk of perforation. Esophageal reconstruction after these injuries is often delayed, and staged, allowing adequate tissue stabilization before further manipulation. Here, we report on a 25 year-old woman who presented with a high-grade caustic esophageal injury following the ingestion of an alkaline drain cleaner. She underwent an emergent thoracic esophagectomy, gastrectomy and a cervical salivary esophagostomy. Post-operatively, she developed supraglottic and hypopharyngeal strictures, but maintained a functional larynx. She subsequently underwent a staged, extrathoracic total esophageal reconstruction using an anterolateral thigh (ALT) myocutaneous free flap with laryngeal preservation. Although serial esophageal dilatations and trans-oral laser procedures for pharyngeal strictures were required, she was able to maintain the ability to swallow.
