Abstract

<p>An 84-year-old female, with no history of abdominal surgery, presented with complaints of abdominal pain and nausea. Computed tomography (CT) revealed a dilated small intestine with an internal hernia pointed cranially beyond the transverse colon. Thus, an internal hernia involving the transverse mesocolon was suspected and emergency laparotomy surgery was performed. The small intestine within the hernial sac was incarcerated into the omental bursa through the defect of the transverse mesocolon. No ischemic changes were detected in the incarcerated intestine. Transmesocolonic hernias are rare, and only represent 12.2% of all mesocolonic hernias. Transmesocolonic hernias are classified into two types : one type which involves the bilateral transverse mesocolon, and another which involves the unilateral transverse mesocolon. This case was classified as the latter type. Today, a few reports indicate that multi-detector row computed tomography (MDCT) enables diagnosis of transmesocolonic hernias. Using MDCT, we could diagnose the transmesocolonic hernia preoperatively.</p>
