On CT imaging, the small bowel feces sign appears as a mottled, mixed-density pattern within a distended small bowel loop. It is typically located proximal to the site of obstruction and is often accompanied by other features of small bowel obstruction, such as: [5] Dilated bowel loops: Loops proximal to the obstruction exhibit dilation (>2.5-3 ...

The fibrous Ladd's bands can constrict the duodenum, leading to intestinal obstruction.
