Extraction of an ingested denture embedded in the jejunum by mucosal cutting.

A 55-year-old woman accidentally ingested a denture, and it did not pass per anus after 4 days. Her local doctor followed her for 15 days, but the denture did not pass, and she was referred to our institution. She did not complain of any abdominal symptoms, and laboratory data did not show any abnormal findings. Abdominal radiograph (▶Fig. 1) and computed tomography scan showed a denture lodged in the jejunum. Antegrade double-balloon enteroscopy showed sharp, elongated teeth embedded in the jejunal mucosa (▶Fig. 2). Forceps extraction was attempted first but was unsuccessful because the elongated part of the denture was lodged deep in the mucosa. Five days later, forceps extraction was attempted again using a short double-balloon endoscope, but the hook prevented extraction. Next, using endoscopic ultrasonography, we confirmed that the hook of the denture was in the thickened mucosal layer of the jejunum. Therefore, after injecting normal saline into the submucosa, we cut the mucosa with a needle-knife (▶Fig. 3). After freeing it from the mucosa, the denture was extracted endoscopically. Foreign bodies in the small intestine are relatively rare, but they do risk perforation and therefore necessitate surgical intervention [1]. Nakamura et al. reported three patients with ingested dentures among 22 patients with foreign bodies in the small intestine [2]. Although forceps extraction of dentures was successful in two of the three patients, one remained deep in the ileal wall and was removed surgically after failure of endoscopic extraction [2]. In the present case, we overcame the problem of the denture hook being stuck in the jejunal mucosa by using the endoscopic mucosal cutting technique and extracting the denture without surgery. In conclusion, mucosal cutting during double-balloon endoscopy is useful for the extraction of a sharp foreign body embedded in the small intestine, after confirming the depth of embedment.
