A rare case of small bowel obstruction

Internal hernias account for approximately 5 percent of cases of small bowel obstruction (SBO) with more than 50% mortality rate. Transomental hernia is very rare, accounting to 1-4% of all internal hernias. So it is a very unusual cause of SBO. We reported a 69 year-old man who presented with SBO signs and symptoms. Early diagnosis and exploration revealed a segment of congested small bowel loop herniated through a defect over the greater omentum. This case is presented for its rarity and its importance in causes of SBO, especially in patients without history of abdominal surgery or trauma
