투시 촬영을 이용한 하인두 점막하 이물 제거: 증 례 보 고

A 64-year-old woman visited to our hospital for foreign body sensation of throat and odynophagia following meal. A neck lateral radiograph revealed a wire-shaped metallic foreign body at the hypopharynx. Although we investigated the hypopharynx and esophagus throughout using rigid esophagoscope, we couldn’t find out it. Pharyx computed tomography showed the foreign body under the mucosal layer, and it was removed by submucosal dissection under fluoroscopic control. Repeated trial of rigid esophagoscopy raise the chance of complications such as esophageal mucosal injury, esophageal perforation, and cervical vertebrae injury. If foreign body cannot be found out despite repeated trial of rigid esophagoscopy, the possibility of submucosal migration should be considered. Fluoroscopically guided esophagoscopy is a safe and effective technique for the removal of submucosal foreign body. (J Clinical Otolaryngol 2000;11:326-329)
