A spontaneous transomental hernia through the greater omentum

Transomental hernia is the rarest form of internal hernias. Clinical expression of this pathology is ambiguous and diagnosis is often made at complication phase, after irreversible strangulation of the herniated loop. Radiological diagnosis is still difficult and intraoperative exploration usually allows discovering this pathology when patient is operated for acute intestinal obstruction. Treatment is surgical and aims to treat intestinal obstruction and prevent recurrence. We describe the case of a 65 years old male operated for a preoperatively suspected internal hernia; surgical exploration found a transomental hernia trough the greater omentum.
