Comparison of Endoscopy Alone with Surgery Converted from Endoscopy for the Removal of Esophageal Foreign Bodies in Adults: A Retrospective Study from a Single Center

BACKGROUND: The impaction of an esophageal foreign body is an urgent situation requiring emergency intervention. This retrospective study from a single center in China aimed to compare endoscopy alone with surgery converted from endoscopy for the removal of esophageal foreign bodies in adults. MATERIAL/METHODS: A total of 252 patients with esophageal foreign bodies were divided into 3 groups based on the treatment received: endoscopy, surgery converted from endoscopy, or surgery only. Patients’ clinical and demographic data were retrospectively reviewed and analyzed. RESULTS: The diameter of the foreign bodies in patients treated by surgery converted from endoscopy was larger than that of those treated by simple endoscopy (5.2 cm vs 2.7 cm, P=0.0003). The cervical or upper thoracic esophagus was the most common site of foreign body impaction treated by surgery converted from endoscopy, while the foreign bodies removed by simple endoscopy were frequently lodged at the middle thoracic esophagus (P=0.021). Bone-related foreign bodies and dentures were most likely impacted in patients treated with surgery converted from endoscopy. The factors influencing the choice of treatment included foreign body maximal diameter and location. CONCLUSIONS: Larger foreign bodies that were found in the cervical or upper thoracic esophagus were associated with failed endoscopic removal and required surgical removal. Irregularly shaped or sharp foreign bodies, including dentures and fishbones, required surgical removal. These findings may guide future decisions of first-line approaches for the removal of esophageal foreign bodies.
