[Accidental ingestion of dental prostheses; 2 scenarios in the management and outcome. Case reports].

BACKGROUND: Foreign body ingestion is the second cause of endoscopic emergency in the elderly, and dentures are the most frequent accidently ingested objects. Once in the stomach, their expulsion can be expected in 4 to 6 days. The treatment is wait and see in asymptomatic patients, but preventive endoscopic removal can also be performed. OBJECTIVE: To present 2 scenarios of the outcome and treatment in patients with foreign body ingestion. CASE REPORT: Patient under study due to weight loss, with a denture detected by abdominal x-ray, ingested inadvertently a year ago. A laparotomy was required as extraction by colonoscopy failed, due to excessive inflammation. The second case, of 24-hour onset, was due to the ingestion of a partial denture. As duodenal endoscopy extraction was unsuccessful, the patient was kept under observation. When it did not pass the caecum, it was extracted by colonoscopy, with no further complications and shorter hospital stay. CONCLUSIONS: Follow-up can be by simple abdominal x-ray, with endoscopic management if there is insufficient progress. In one of our cases, the outcome was unfavourable due to time of ingestion, and endoscopic management was not possible, whereas in the second case colonoscopy was performed early with success. Proper diagnostic and timely treatment mark the difference in the progression and outcome of the ingestion of foreign bodies.
