title: Incidentally found Killian-Jamieson diverticulum due to an embedded fish bone.
abstract: We report the first case of Killian-Jamieson diverticulum (KJD) found because of an embedded fish bone. A 52-year-old female patient presented with a foreign body sensation after accidentally ingesting a fish bone. A plain x-ray revealed a linear hyperopaque lesion in the upper esophagus, but the foreign body could not be found on flexible esophagoscopy. Enhanced neck CT revealed an esophageal diverticulum containing a long embedded fish bone. After removing the bone via rigid esophagoscopy under general anesthesia, pharyngoesophagography confirmed the KJD without contrast leakage. Any pharyngoesophageal diverticulum found following accidental fish bone impaction should be evaluated closely radiologically, such as with CT and a barium esophagogram, to rule out complications such as esophageal perforation. For a small KJD, not a Zenker diverticulum, resection via an open approach is more reliable than endoscopic diverticulostomy due to the difficult transoral manipulation and possibility of recurrent laryngeal nerve damage.
