The parents of a 2 week old term baby presented to the out of hours general practice service late in the evening with a two hour history of green vomiting. As the baby looked well, had been passing stools and urine normally, and had a soft non-tender abdomen, they were advised to attend their own general practice the following morning. The baby arrived in the local emergency department by ambulance six hours later with intractable shock. After aggressive resuscitation, the baby was taken to theatre for emergency laparotomy that revealed intestinal ischaemia from midgut volvulus associated with malrotation.
What is intestinal malrotation and volvulus?
Intestinal malrotation occurs because of failure of the normal sequence of rotation and fixation of the bowel (fig 1⇓). Duodenal obstruction can occur due to extrinsic compression from bands leading from the caecum to the lateral abdominal wall (Ladd’s bands) or from small bowel volvulus, which also leads to ischaemia of the midgut from superior mesenteric artery occlusion (fig 2⇓).1 Midgut volvulus can lead to irreversible intestinal necrosis, which is potentially fatal.1
