Small bowel faeces sign.
It is an uncommon but highly specific sign of small bowel obstruction (SBO) on CT scan of the abdomen, particularly in patients with low-grade or intermittent obstruction. (2) The adjacent transition zone and the distal collapsed bowel loops indicate the level of obstruction. The most common cause of the SBO is adhesions. Other common causes are inflammation, tumours and hernias. Small bowel faeces sign may also indicate severe metabolic or infectious pathology of the small bowel.
The clinical signs of SBO are difficult to distinguish from local or generalised paralytic ileus; therefore an early radiological diagnosis is very important.
