Reconstructed enhanced multidetector-row computed tomography reveals the following: (A) before the surgical repair of the right paraduodenal hernia, the aorto-mesenteric angle is 44°, and the aorto-mesenteric distance is 28 mm. There are intestinal gas bubbles under the aorto-mesenteric junction. (B) After the repair, the aorto-mesenteric angle has narrowed to 14°, and the aorto-mesenteric distance has shortened to 5 mm. Furthermore, no intestinal gas can be seen under the angle.
