Background: The development of endoscopy, over the last three decades, and the widespread access for patients has rendered it the first line treatment for patients presenting with foreign body ingestion. We report the successful endoscopic removal of an ingested thermometer from the stomach of a young female.
Case Report: A 35 years old female patient presented with foreign body ingestion which was successfully managed by endoscopic means. We report the preparation of the patient and the instrumentation; we review the general principles in dealing with ingested thermometers and mercury toxicity.
Conclusions: An ingested thermometer can easily be recovered by means of endoscopy from the stomach. A
multidisciplinary approach in cooperation with surgeons and anesthesiologists is certainly advisable, as is endoscopic skill.
