Can you tell me pyloric stenosis long term effects?

Usually none: A pyloric stenosis if treated appropriately will have no long term effects. The surgery used to treat it is minor and well tolerated.

Usually fine: Usually once diagnosis is made and patient has surgery, pyloromyotomy the outcome is very good with resumption of normal feedings.Rarely does this condition recur. Deformity of narrow pylorus remains but surgery widens enough for liquids and chewed foods to pass.if child swallows foreign body such as coin or marble, prolonged retention in stomach occurs because exit from stomach not large enough.
