A case of strangulated transomental hernia diagnosed preoperatively.

A patient with an unusual case of internal hernia was treated successfully with surgery for strangulated transomental hernia, diagnosed preoperatively by abdominal computed tomographic examination (CT). The herniation occurred through congenital defects in the gastrocolic omentum. Herniation of this nature is extremely rare, and abdominal CT examination is very useful for preoperative diagnosis.
