Volvulus other imaging findings

Barium enema may be helpful in the diagnosis of sigmoid volvulus. In some instances, barium enema may be able to reduce sigmoid volvulus. Findings on barium enema suggestive of sigmoid volvulus include a twisted tapering known as a bird beak configuration. Barium study is contraindicated in the presence of necrotic bowel or pneumoperitoneum.

• Barium enema may be helpful in the diagnosis of sigmoid volvulus in conjunction with plain radiography.^[1]
• Findings on barium enema suggestive of sigmoid volvulus include a bird’s beak appearance representing the dilated area of bowel proximal to the obstruction.
• There is a high risk for perforation and peritonitis, so the enema is performed under fluoroscopic guidance.
• Barium study is contraindicated in the presence of necrotic bowel or pneumoperitoneum.
