Small bowel obstruction caused by Meckel's diverticulum enterolith: case report

Abstract

Meckel Diverticulum (MD) is a relatively common congenital anomaly, but is rarely diagnosed because it is usually asymptomatic. Most of the symptomatic MD presents as intestinal bleeding in children. Enterolith is a rare complication in MD, because the conditions supposed to be necessary for the stones formation (stasis and alkaline environment) are uncommon. Enteroltith formation have been reported in those MD with narrow neck (witch contributes to stasis) and absence of ectopic gastric mucosa (witch allows the development of a alkaline environment). The most common symptom is recurrent abdominal pain. The image findings are stones seen in the plain films or in the interior of the intestine wall at CT. This report is different from the previous by showing enteroliths in a MD with ectopic gastric mucosa and a wide neck communicating the diverticulum to the intestinal lumen.
