Volvulus
Volvulus – Midgut, barium swallow
Midgut volvulus is a result of a rotational anomaly of the gastrointestinal tract. The small bowel mesentery has twisted at the root with a vascular twirl of the SMA/SMV. This then sets up a potential for vascular compromise. [Courtesy of Dr. N. Jaffer]
Small Bowel Obstruction – String
Small Bowel Obstruction – String of Pearls (AXR & CT)
The “string of pearls” sign in the images above is caused by air trapped at corners of valvulae conniventes. This is almost always seen in obstructed fluid filled loops of small bowel.
