Acute necrotizing Meckel diverticulitis due to biliary enterolithiasis.

Background: Acute abdominal pain due to complicated Meckel's diverticulum is an unusual event. Even the presence of biliary enterolithiasis at the onset of inflamed congenital diverticulum has rarely been reported previously.
Results: Despite this unusual presentation, an episode of gallstone passage through the biliary tract has not yet been described.
Conclusions: Whether the stones were primarily formed in the diverticulum as enterolithiasis, or secondary to gallstone passage is discussed. The complications of Meckel's diverticulum requiring surgical treatment are reviewed, focusing on the unusual finding of biliary stones in Meckel's diverticulum and the etiogenic mechanism of enterolithiasis.
