1 Small-bowel obstruction
Small-bowel obstruction. (A) AP supine radiograph of the abdomen with SBO with multiple dilated loops. In contrast to large-bowel obstruction (LBO), notice the more central position and mucosal folds extending completely across the loop of bowel, representative of the valvulae conniventes (white arrow). (B) Upright AP radiograph of the abdomen of same patient showing multiple differential air-fluid levels with dilated loops of bowel. Given enough time, with a high grade SBO, the distal bowel including the colon and rectum will be devoid of air as in this case.
