Radiology of sigmoid volvulus

Sigmoid volvulus is often a surgical emergency. The diagnosis is usually reached on the basis of both clinical and radiolotic assessment. A review of the radiologic findings in 20 patients diagnosed as having sigmoid volvulus is presented. Typical radiographic features are illustrated. Reasons for their absence in certain cases are discussed.

Two cases of poststernotomy mediastinitis and sternal wound reconstruction with a pedicled omental flap were complicated by a large anterior diaphragmatic hernia containing the large bowel.
