title: Inverted Meckel's diverticulum with ectopic pancreatic tissue as a source of severe gastrointestinal bleeding.
abstract: BACKGROUND
  Meckel's diverticulum is the most common congenital anomaly of the gastrointestinal tract. Authors present a 67-year-old woman treated for iron deficiency anemia for the past 5 years. Suddenly, her disease was presented with painless severe gastrointestinal bleeding (fresh melena). Inverted Meckel's diverticulum with ectopic pancreatic tissue as a source of severe gastrointestinal bleeding was diagnosed by intraoperative enteroscopy.
  
  
  CONCLUSIONS
  A combination of inversion of Meckel's diverticulum with ectopic pancreatic tissue is extremely rare, particularly in elderly patient. Capsule endoscopy, double balloon enteroscopy, and ultimately intraoperative enteroscopy may be helpful in timely diagnosis.
