Primary torsion of the greater omentum. Case report

Four cases of primary torsion of the greater omentum are reported. The most common clinical picture in this condition mimics acute appendicitis. Primary torsion with spontaneous derotation of the greater omentum may be an important cause of right iliac fossa pain of obscure origin. Scrutiny of the omentum during negative appendiceal exploration is extremely important. Treatment is excision of the twisted, infarcted omentum.
