Small bowel faeces sign(SMA-Syndrom)
It is defined by the presence of particulate faeculent material mingled with gas bubbles in the lumen of the small intestine (as seen in the colon on CT) . It is the result of delayed intestinal transit and is believed to be caused by incompletely digested food, bacterial overgrowth, or increased water absorption of the distal small-bowel contents due to obstruction .
The sign has been described as a finding indicative of small bowel obstruction (SBO) or another severe small-bowel abnormality (ie, metabolic or infectious disease). The reported prevalence of the sign in SBO is however low (7 – 8%)1.
