A 48-year-old man accidentally swallowed his upper partial denture while asleep, at about 4 o’clock in the morning. He thought he was dreaming and continued to sleep. However, when he woke up around 7 o’clock, he realized that he was missing his upper denture, and 1 hour later, he presented to our emergency room. A plain film of the abdomen confirmed his fear ([Fig.1]). On physical examination the patient appeared poorly groomed and disheveled but in no apparent distress. The abdomen was soft and nontender, and bowel sounds were normal. An esophagogastroduodenoscopy (EGD) did not reveal any foreign body in the entire stomach or duodenum. Thus we carried out a small-bowel enteroscopy, using the single balloon technique (i. e., only using the overtube balloon but not placing a balloon on the scope; Fujinon EN-450T5; Fuji, Fujinon Corp., Tokyo, Japan). The missing denture was found at approximately 35 cm from the pylorus ([Fig. 2]). The overtube was advanced towards the tip of the endoscope, and the balloon of the overtube was inflated to provide stability to the small bowel. With an assistant holding the overtube in a straight position, we could easily torque and manipulate the scope in a to-and-fro manner. Once an adequate endoscopic position was achieved, we used a standard oval snare ([Fig. 3 a]) to grasp the most proximal part of the denture ([Fig. 3 b]), which was then pulled out under direct and continuous endoscopic visualization. As the denture could not be brought inside the overtube, we proceeded in the following stepwise fashion: (1) we kept the tip of the overtube close to the tip of the enteroscope; (2) the balloon of the overtube was inflated and deflated while pulling out of small bowel; and (3) we kept insufflating the small bowel. We speculated that with this method, the dilated bowel lumen on the proximal side (overtube and partially inflated balloon) and on the distal side (dilated through air insufflation) would minimize impaction and/or laceration potential of the prosthesis while it was being pulled out. Whereas in the stomach there was a minimal chance of impaction, at the level of the cardia and esophageal sphincter we again carefully inflated and deflated the balloon of the overtube to repeat the maneuver used within the small bowel. The denture was thus successfully removed and returned to the patient, who had it re-cemented by his dentist after discharge.

Most ingested foreign bodies are excreted without any problems. However, large or sharp objects can result in significant complications, such as bowel perforation or an abscess [1]. Dental prostheses are usually large objects, which can get stuck in any part or stricture of the luminal gastrointestinal tract and result in obstruction, fistulae, abscess, perforation, or bleeding [2] [3] [4]. Thus, in the present patient, removal of the denture while it was still in the stomach would have been indicated but it had already migrated into the small bowel. Although the most common foreign bodies removed from the small bowel are retained capsule endoscopes, needles, coins, and migrated gastric bands have also been removed using balloon enteroscopy [5] [6] [7] [8]. This case report is interesting for several reasons. First, we demonstrated that a large denture with six teeth can be removed endoscopically from the small bowel. Second, we have provided a detailed description of the technical procedure, which may facilitate further use of the procedure. Third, our report adds to the expanding literature on therapeutic small-bowel endoscopy. Lastly, the ready availability of deep enteroscopy techniques allowed us to make rapid decisions, switch equipment and scopes with minimal time delay and continue the search for the lost foreign body within the small bowel. In the absence of deep enteroscopy equipment, we recommend transferring the patient as soon as possible to the closest center with this capability as endoscopy may obviate a stressful “wait-and-watch” strategy, a major complication, or the need for a more invasive procedure such as a laparotomy.
