Inverted Meckel's diverticulum diagnosed using capsule endoscopy: A case report

Meckel's diverticulum is a common asymptomatic congenital gastrointestinal anomaly. However, its presentation as an inverted Meckel's diverticulum is a rare complication, of which few cases have been reported in the literature.

Here, we report the case of a 33-year-old man with iron deficiency anemia without manifestation of gastrointestinal bleeding. An upper gastrointestinal endoscopy and total colonoscopy were performed, but no abnormalities were found within the observed area. Finally, a capsule endoscopy was performed and offered us a clue to subsequently confirm the diagnosis of inverted Meckel's diverticulum via computed tomography scan. Laparoscopic intestinal resection surgery was performed. The final pathology report described a Meckel's diverticulum.

Since inverted Meckel's diverticulum is an uncommon disease and its clinical presentation is not specific, it may go undetected by capsule endoscopy. Successful diagnosis and treatment of this disease requires a high index of clinical suspicion.
