Intestinal Malrotation :

the bowel twists on itself, cutting off the blood flow to the tissue and causing the tissue to die. Symptoms of volvulus, including pain and cramping, are often what lead to the diagnosis of malrotation.
Bands of tissue called Ladd's bands may form, obstructing the first part of the small intestine (the duodenum).
Obstruction caused by volvulus or Ladd's bands is a potentially life-threatening problem. The bowel can stop working and intestinal tissue can die from lack of blood supply if an obstruction isn't recognized and treated. Volvulus, especially, is a medical emergency, with the entire small intestine in jeopardy. UcenterDress convertible wears for bridesmaid With twist wrap
