Colonic obstruction secondary to accidental ingestion of a dental prosthesis; case report

Introduction: intestinal obstruction is a common medical emergency, usually caused by mechanical processes such as neoplasms or volvulus. However, obstruction secondary to foreign bodies, although rare, can lead to serious complications, especially when the ingested object is a dental prosthesis. Method: We present the case of a 65-year-old male, with no relevant medical history, who presented with symptoms of abdominal pain, nausea, and absence of bowel movements. Computed tomography revealed an intraluminal foreign body in the sigmoid colon. Given these findings, an exploratory laparotomy with enterotomy and extraction of a dental prosthesis was performed. Results: accidental ingestion of dental prostheses can cause obstruction, perforation, and even intestinal ischemia. This type of event is more common in elderly adults or patients with cognitive impairments, although it can also occur in healthy individuals. Detection is difficult if the patient does not recall the event and if the prosthesis material is radiolucent. Computed tomography is the most useful diagnostic tool in these cases. Management varies depending on the location, type of prosthesis, and presence of complications, ranging from observation to endoscopy and surgery. Conclusions: early and multidisciplinary management is essential to avoid major complications. Prevention includes regular dental check-ups and patient education. This case highlights the importance of considering foreign bodies as a cause of obstruction in atypical clinical contexts.
