Default Signs/symptosm TE fistula, Duodenal Atresia & Pyloric Stenosis

Hey guys can you help me out as to how I can differentiate between

TE FISTULA
DUODENAL ATRESIA
PYLORIC STENOSIS

I ALWAYS GET SO CONFUSED WHEN THEY GIVE THE SIGNS AND SYMPTOMS OF A BABY
ALSO THE TIME FRAME (AS IN WEEKS) OF WHEN IT IS VISIBLE

I KNOW THEY SAY "TWO WEEKS AFTER BIRTH" ETC

THANKS IN ADVANCE GUYS!

pyloric stenosis is gonna be a hypertrophied mass on biopsy plus non-billious vomiting (hasnt reached duodenum) vs duodenal atresia which is billios vomiting and will show a dubble bubble sign (since there is inflammation proximal and distal to it). TE Fistula is a fistual between esopahgus and trachea plus a blind esophagus so right when you try feeding the baby he pukes it out (non billious) also you get air in the stomach coming from the trachea. Thats all i can remember off the top of my head

thanks crunchtime!

So im assuming if they ask about a baby who soon after births starts vomiting, it would be TE fistula?

Pyloric stenosis in FA says there would be vomiting at around 2 weeks of age, when would we see the signs of duodenal atresia? 2 weeks also?
