Thread: Coffee bean sign (Bent inner tube sign)

  1. #1

    Default Coffee bean sign (Bent inner tube sign)

    is a sign on an abdominal plain film of a sigmoid volvulus although some authors have also used the term to refer to closed loop small bowel obstructions. This contrasts to a kidney bean sign which is seen with a caecal volvulus.

    This thick 'inner wall' represents the double wall thickness of opposed loops of bowel, with thinner outer walls due single thickness.

    Coffee bean sign (Bent inner tube sign)

    Sigmoid volvulus is the most-common form of volvulus of the gastrointestinal tract and is responsible for 8% of all intestinal obstructions. Sigmoid volvulus is particularly common in elderly persons and constipated patients. Patients experience abdominal pain, distension, and absolute constipation.

    Cecal volvulus is slightly less common than sigmoid volvulus and is associated with symptoms of abdominal pain and small bowel obstruction.

    Large bowel volvulus accounts for ~5% of all large bowel obstructions, with ~60% of intestinal volvulus involving the sigmoid colon. It is more common in the elderly .

    Symptoms are that of a large bowel obstruction: constipation, abdominal bloating, nausea and/or vomiting. Onset may be acute or chronic.
