After the water-soluble enema, abdominal distension eased and the baby started to stool normally. They were observed for a further 48 hours and then discharged with no further imaging.

Appearances here are of meconium plug syndrome. This affects the left colon and causes obstruction. The enema is therapeutic as well as diagnostic and often promotes meconium plugs to be expelled. The colon is normal and there are no sequelae.

Differentials are for failure to pass meconium and include meconium ileus (should have right-sided filling defects and microcolon).
