Computed tomography of lesser sac hernia through the gastrohepatic omentum

This is the authors' abstract. We don't add key points for this paper.

Internal hernia is an unusual cause of intestinal obstruction and pre-operative diagnosis on plain films has seldom been made. Before the introduction of computed tomography (CT), the literature on the subject was composed principally of case reports, often based on observations made at surgery or autopsy. However, with the increasing use of CT, pre-operative diagnosis of paraduodenal hernias has been made (Passas et al, 1986; Day et al, 1988). We report a case of lesser sac hernia through a rare congenital defect in the gastrohepatic omentum. The diagnosis, based on the findings of CT, was made pre-operatively. The CT appearance of the condition has not been described in the literature previously.
