Sigmoid volvulus This occurs in cases of long-standing chronic constipation where patients develop a large, elongated, relatively atonic colon, particularly in the sigmoid segment. It is often referred to as acquired or idiopathic megacolon. In sigmoid volvulus, a large sigmoid loop full of faeces and distended with gas twists on its mesenteric pedicle to create a closed-loop obstruction.
