Retrievable Silicone-Covered Esophageal Stent-Assisted Endoscopic Extraction of a High-Risk Clasp-Retained Denture Impacted at the Aortic Arch Level of the Esophagus: A Case Report.

INTRODUCTION

Clasp-retained dentures are high-risk esophageal foreign bodies that carry a substantial risk of severe esophageal injury. Reliable protection strategies are therefore critical for safe endoscopic extraction. We present a case of successful endoscopic removal of a clasp-retained denture impacted at the aortic arch level using a retrievable silicone-covered esophageal stent as a protection device.

CASE PRESENTATION: A 50-year-old man with hypertension and coronary stent implantation was admitted with retrosternal pain and dysphagia for 4 h after accidental ingestion of a broken denture. Computed tomography confirmed a 1.3 × 2.0 × 4.7 cm foreign body impacted at the aortic arch level. The foreign body was successfully removed under general anesthesia with tracheal intubation, and no intraoperative complications occurred. Postoperative recovery was uneventful. Telephone follow-up at 1 week, 1 month, and 3 months showed that the patient had a normal diet with no discomfort, and the patient declined endoscopic reexamination.

CONCLUSION

This case confirms that a retrievable silicone-covered esophageal stent is a safe and feasible protection device for endoscopic extraction of high-risk dentures at the aortic arch level, with favorable short- and medium-term outcomes. It provides a valuable clinical reference for managing such life-threatening foreign bodies.
