Overview

Familial intestinal malrotation is a rare inherited condition where the intestines do not rotate and settle into their normal position during fetal development. In a typical pregnancy, the intestines twist into place in a specific way before birth. In people with this condition, that rotation is incomplete or happens incorrectly, leaving the bowel in an unusual position inside the abdomen. This is sometimes called familial midgut malrotation or hereditary intestinal malrotation. Because the intestines are not anchored properly, they are at risk of twisting around themselves — a dangerous complication called volvulus. This can cut off the blood supply to the bowel and become a medical emergency. Symptoms can include vomiting (often with bile, which looks green or yellow), belly pain, bloating, and feeding difficulties. Some people have mild symptoms for years before a diagnosis is made, while others have a sudden, severe episode early in life. Treatment usually involves surgery called the Ladd procedure, which untwists the bowel, widens the attachment points, and removes the appendix to prevent future confusion with appendicitis. When caught early and treated promptly, many people do well after surgery. Because this condition runs in families, relatives of an affected person may also need to be checked.

Key symptoms:

Vomiting with green or yellow (bile-stained) fluidSevere or recurring belly painBloating or a swollen abdomenDifficulty feeding or poor weight gain in infantsConstipation or irregular bowel movementsDiarrheaFeeling full quickly when eatingNauseaBlood in the stool (in severe cases)Failure to thrive in babies and young children
