Case Discussion

Sigmoid volvulus is an abnormal twisting of the sigmoid colon along its mesenteric axis that causes closed-loop obstruction and can lead to ischaemia, perforation, and death. 

The coffee-bean 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.
