Pyloric Stenosis and Pylorospasm

               --------------------------------

                      General Information



The pylorus is the short muscular passage between the stomach and

the small intestine.  Normally it remains closed, allowing the

stomach to fill with food;  then it opens in rhythm with the

stomach contractions, allowing food to pass into the small

intestine.  In pylorospasm, the muscle fails to relax and allow

food to pass from the stomach.  This results in vomiting of

undigested food.  Pyloric stenosis is a narrowing of the pylorus.

This condition also interferes with the passage of food from the

stomach, and vomiting is the usual result.  Pyloric stenosis may

be present since birth (congenital) or the result of chronic

infection, untreated pylorospasm, or a tumor of the pylorus.

Radiographs (x-rays) or exploratory surgery may be required to

reach a final diagnosis.

                 Important Points in Treatment



1.  Pylorospasm is treated by dietary control, medication to

    prevent spasm, and occasionally tranquilizers.  Chances for

    control and possible cure are very good;  however, prolonged

    treatment may be necessary. 



2.  Pyloric stenosis is treated by surgery to enlarge the

    pylorus.  If the condition is congenital, the chances for

    cure are excellent.  If it is due to other causes, chance for

    complete cure are fair.
