Rigid esophagoscopy combined with angle endoscopy for treatment of superior mediastinal foreign bodies penetrating into the esophagus caused by neck trauma: A case report

BACKGROUND Herein, we report a case in whom two foreign bodies entered the upper mediastinal cavity from the cervical root and subsequently the esophagus.Surgery is the preferred treatment method, and operational procedures depend on the size and location of the foreign body relative to the mediastinal vessels.Rigid esophagoscopy combined with angle endoscopic surgery was selected to avoid surgical trauma and complications.CASE SUMMARY A 63-year-old male patient with a 6-mo old history of neck trauma presented with a black-brown foreign body in the lateral wall of the esophagus. Neck and chest computed tomography(CT) revealed that two superior mediastinal foreign bodies penetrated the esophagus diagonally. We removed two foreign bodies through an esophagoscope. Owing to the rigid working channel of esophagoscope and good exposure of endoscope, the risk of injury to the adjacent vital tissues was minimized. Postoperative comprehensive therapies, including antibiotic administration and nutritional support, resulted in a prompt postoperative recovery. Postoperative CT confirmed the absence of a residual foreign body and neck and chest infections. In addition, upper gastrointestinal angiography and gastroscopy revealed the absence of an evident esophageal perforation. The patient received an oral diet and did not experience any complication at the time of discharge from the hospital.CONCLUSION Rigid esophagoscopy combined with angle endoscopy is an effective, minimally invasive treatment for penetrating neck injuries.
