Is meconium plug syndrome only associated with cystic fibrosis?

Not only, but often. No. Certainly patients with meconium plug have a higher risk of CF and must be tested, many babies with this do not have cf. Hirschsprung's disease should also be tested for.
No. Meconium plug syndrome, as opposed to meconium ileus, is not necessarily associated with cf. It can occur with hirschsprung's disease. It is usually self-limited, however, and clears with a contrast enema undertaken to establish the diagnosis. If the baby stools normally after initial evacuation, additional work-up is usually not necessary.
No. It can be associated with maternal diabetes, small left colon syndrome, hirschsprung's disease, or electrolyte imbalances in the infant.
No. Meconium plug syndrome can occur as an isolated event. It can also be associated with other genetic conditions such as hirschsprung disease.

My baby was born 4 weeks early and had a meconium plug that didn't pass till hour 57. Cystic fibrosis has been ruled out. What are the chances it's hirschsprungs? Or could it just be chance?

Likely it's chance. CF is one of the causes of meconium plug, but mostly it's a random happenstance. Ruling out CF is important. As long as your child is starting to have normal stools now, and they are fairly regular, it's very unlikely it's hirschsprungs. Generally anal stenosis, hirschsprungs, or other forms of obstruction would cause chronic constipation. If your child is stooling normally, i'd go with it. Read more...

What is the difference between meconium aspiration and meconium ileus in cystic fibrosis?

See below. Meconium is normal intestinal fluid in an unborn child. If the meconium becomes too thick to pass through the intestines it can cause a blockage.

CF kids have poo that's too sticky & won't pass. Read more...
