Gunshot injuries of the lower oesophagus.

Abstract

We present seven cases of lower oesophageal gunshot injury cared for by one surgeon. Diagnosis was made clinically, with the help of chest X-rays and with oesophagography and oesophagoscopy. Five were treated with wide debridement and resection of the distal esophagus and oesophago-gastric anastomosis with a Nissen wrap to protect the anastomosis. Two lesser injuries were treated by primary repair. The five treated with resection and oesophago-gastric anastomosis did not leak and the patients were discharged after oesophagography 10 days postoperatively. Primary repairs in two patients were complicated by oesophageal leaks, one subclinical and one with an empyema. The oesophageal blood supply is segmental in areas and variable in the distal part. Injury due to a bullet wound may cause more damage than is evident at surgery. Additional mobilization can further devascularize the distal oesophagus and lead to anastomotic leaks. We advocate wide debridement of oesophageal gunshot injuries and resection of the distal oesophagus. Continuity is restored with a primary oesophago-gastric anastomosis (double layer) with a fundoplication to protect the anastomosis.
