A rare type of lesser sac hernia.

We report herein the case of a female who developed a lesser sac hernia which was a rare type and was strangulated by a hole in the posterior layer of the lesser omentum. In our patient, abdominal computed tomography showed a loop of distended intestines among the liver, gallbladder and stomach. To our knowledge, there has been no previous report of transomental hernia exactly like our present case.
