Endoscopic evaluation of penetrating esophageal injuries.

There are few objective data evaluating the role of flexible endoscopy in the management of penetrating esophageal and neck injuries. A retrospective analysis was performed on 13 trauma patients who had undergone emergent esophagogastroduodenoscopy for the evaluation of potential esophageal injuries. Endoscopy resulted in one true positive (esophageal injury detected), 10 true negatives (normal esophagus), two false positives, and no false negatives. This yielded a sensitivity of 100% and specificity of 83%. There were no complications of endoscopy. We conclude that urgent flexible esophagogastroduodenoscopy is a useful diagnostic procedure in the evaluation of penetrating wounds possibly involving the esophagus.
