Management of an Unusual Avulsion Trauma of Total Esophagus During Upper Gastrointestinal Endoscopy.

Abstract

An esophageal defect usually resulted from surgical ablation of tumors or corrosive injury. Staged reconstructions are required usually in extensive defects. This study aimed to present a rare iatrogenic complication of total esophageal avulsion injury during upper gastrointestinal endoscopic treatment and to perform staged reconstructions to create a neoesophagus. In the presented case, staged reconstructions with a tubed deltopectoral flap and a supercharged colon interposition flap were performed to reconstruct the hypopharynx and esophagus. However, recurrent choking occurred because of the extent of injury involving the epiglottis. A tubed free radial forearm flap connected to the lower buccogingival sulcus was used to create a new route for food passage. The patient resumed oral intake after rehabilitation. The avulsion injury of the total esophagus is rare and devastating. Staged reconstructions with a tubed deltopectoral flap, a supercharged colon interposition flap, and a tubed free radial forearm flap would be a safe and reliable method.
