Abstract
BACKGROUND

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.

CASE SUMMARY

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.

CONCLUSION

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.

Keywords: Inverted Meckel’s diverticulum; Capsule endoscopy; Anemia study; Small bowel tumor; Case report

Core Tip: Inverted Meckel’s diverticulum is an uncommon disease with a wide spectrum of accompanying nonspecific symptoms. We present, here, a case of iron deficiency anemia with negative endoscopic study, in which capsule endoscopy played a key role in confirming the diagnosis. Since inverted Meckel's diverticulum is an uncommon disease with few cases described in the literature, this report aims to contribute more information concerning the clinical characteristics as well as radiological and capsule endoscopy findings of inverted Meckel’s diverticulum that can help clinicians make the correct diagnosis.
