Paraduodenal hernias also known as congenital mesocolic hernia or retroperitoneal hernias is defined as protrusion of bowel into the retroperitoneal space through peritoneal defects near the third and fourth portion of duodenum. Though the disease is rare, the lifetime risk of obstruction and bowel strangulation is around 50% with a mortality of 20% and higher. We report a case of left paraduodenal hernia in a young adolescent male with intestinal obstruction, who underwent subsequent laparotomy with hernia repair.
