[2] [5] Either the small bowel or large bowel may be affected. [1] Signs and symptoms include abdominal pain, vomiting, bloating and not passing gas. [1]
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 ...

Small bowel transit time is normally 2.5–6 hours and is calculated from the time the pH increases by more than three units to the time it drops by more than one unit and is sustained for at least 30 minutes. This drop denotes the capsule's passage to the cecum. The colon transit period (normal is 59 hours or less) is calculated from the time ...
