Overview
An x-ray (with or without contrast) may be helpful in the diagnosis of volvulus. Findings on an x-ray suggestive of sigmoid, cecal and ileal volvulus include: U-shaped, distended segment of colon seen as an ahaustral collection of gas volvulus. Findings on an x-ray suggestive of gastric volvulus includes a single, large, spherical gas bubble located in the upper abdomen or chest with an air-fluid level. It is important to rule out pneumoperitoneum before carrying out a barium enema.
X Ray
- A plain x-ray without contrast may be helpful in the diagnosis of volvulus. Findings on an x-ray suggestive of volvulus include:[1][2][3]
- The following result of plain x-ray with contrast barium enema is indicative of volvulus:
- Bird beak appearance or twisted tapering of afferent and efferent colonic segments
- Plain x-ray with contrast barium enema can be utilized in the following circumstances:
- Plain x-ray with contrast barium enema is contraindicated in:
- Peritonitis
- Pneumoperitoneum
- Necrotic bowel
It is important to rule out pneumoperitoneum, this means that a perforation in the bowel has occurred and that air is in the peritoneum. It is a surgical emergency.
