(1) Malrotation is twisting of the intestines (or bowel) caused by abnormal development while a fetus is in utero, and can cause obstruction. Malrotation occurs in 1 out of every 500 births in the United States.
Some children with intestinal malrotation are born with other associated conditions, including:
Some kids with malrotation never experience complications and are never diagnosed. But most develop symptoms during infancy, and the majority are diagnosed by 1 year of age. Although surgery is required to repair malrotation, most kids will go on to grow and develop normally after treatment.
(2) Intestinal malrotation is a birth defect involving a malformation of the intestinal tract. Intestinal malrotation is an abnormality that occurs while a fetus is forming in its mother's uterus.
Malrotation occurs when the intestine does not make these turns as it should.
In addition, intestinal malrotation causes the cecum (the end of the small intestine) to develop abnormally. The cecum is normally located in the lower right side of the abdomen. With malrotation, the cecum and the appendix (which is attached to the cecum) stay in the upper right side of the abdomen. Bands of tissue called Ladd's bands form between the cecum and the intestinal wall and can create a blockage in the duodenum (the beginning of the small intestine).
A volvulus is a problem that can occur after birth as a result of intestinal malrotation. The intestine becomes twisted, causing an intestinal blockage. This twisting can also cut off the blood flow to the intestine, and the intestine can be damaged.
