Ingestion of a Foreign Body Unmasks an Asymptomatic Small Bowel Carcinoid Tumor

Bowel obstruction is a common surgical admission around the world. On the other hand, small intestinal tumors, such as midgut carcinoid, are uncommon neoplasms and an infrequent cause of intestinal obstruction leading to hospitalization. A foreign body is an extremely rare cause of intestinal obstruction and when ingested, foreign bodies most often lodge in the narrowest portion of the gastrointestinal tract. Narrowing of the small bowel due to a neoplasm can prohibit the passage of an accidentally ingested foreign object and produce an obstruction that neither the neoplasm nor the foreign body could have produced alone. We hereby report a case in which an accidentally ingested piece of foreign material leads to the finding of a small, early stage, asymptomatic, midgut carcinoid cancer in the proximal ileum that would have otherwise eluded detection for several years.
