Internal hernia is herniation of a viscus, usually in the small bowel, through a normal or abnormal aperture within the peritoneal cavity. Its incidence has been reported to be one to two per cent. Internal hernias are classified based on location, and the hernial orifice can be either congenital or acquired. Paraduodenal hernias are the most common type (53 per cent). Paraduodenal hernia is often a misnomer and is referred to as a mesocolic hernia. Left and right mesocolic hernias are common, while middle and transverse types are rare. We are reporting a rare congenital middle mesocolic hernia presenting as a complete transection of the small intestine due to blunt injury to the abdomen.
