Omental torsion as a possible cause of acute abdomen.

Primary torsion of large omentum is a rare cause of abdominal pain. The knowledge of this disease is essential for surgeons. It plays an important role in differential diagnosis of acute abdomen. The authors present two cases of primary omental torsion. They describe the diagnostic and therapeutic process. Diagnosis of omental torsion is difficult. Frequently, it presents with abdominal pain and imitates other acute abdominal diseases such as acute appendicitis in most cases. It is difficult to diagnose before surgical revision is approached. Laboratory and paraclinical examinations may not provide any clear findings. Laparoscopic revision is the method of choice, with confirmation of the diagnosis and laparoscopic resection of the ischemic part of omentum.
