Meckel's diverticulum is the most common congenital abnormality of the gastrointestinal system. It usually has an asymptomatic course and is detected incidentally during laparoscopy. Symptomatic cases are mostly observed under two years of age. In adults, it may rarely manifest with life-threatening complications. In this report, we present a 19-year-old case with Meckel's diverticulum operated with ileus while under follow-up, who was assumed to have Crohn's disease.
