Omental torsion is a rare cause of an acute abdomen. Symptoms are nonspecific and easily mistaken with other more common intra-abdominal pathologies (e.g. acute appendicitis and cholecystitis). The widespread and increasing use of computed tomography (CT) has played an important role for making a specific diagnosis. However, the intraoperative diagnosis rate of omental torsion is still quite high. Objectives: This work aims to describe two patients with diagnosis of omental torsion in terms of clinical and paraclinical symptoms, management strategies and review of the literature confirming the diagnosis as well as the treatment attitude of this rare disease. Case report: We present two patients who were diagnosed and urgently operated for torsion of primary omentum at the Department of General Surgery- Hanoi Medical University Hospital, the patients underwent laparoscopic surgery to remove necrotic omentum. The postoperative course was favorable, the patients recovered and were discharged from the hospital. Conclusion: Omental infarction generally presents with nonspecific clinical signs often masquerading as other more common abdominal diagnosis. Laparoscopically omentectomy is a safe method in diagnosis and management of this condition.
