title: Secondary omental torsion in children: report of two cases and review of the literature.
abstract: Torsion of the greater omentum (TGO) may be due to a congenital abnormal attachment of its free edge. There are no specific symptoms that allow a preoperative differential diagnosis of this condition from common pathologies such as acute appendicitis. Attachment of the omentum to the large bowel and the absence of concomitant diseases make it possible to distinguish TGO secondary to a congenital attachment anomaly from omental infarction, primary TGO, and TGO secondary to an acquired attachment anomaly (attachment to cysts, tumours, hernias, surgical scars, or perforated bowel segments). Resection of the ischaemic portion of the omentum permits complete resolution of the clinical symptoms. The authors report two cases of TGO in children due to abnormal attachment of the greater omentum to the ascending and transverse colon, respectively.
