At a pyloric stenosis of a muscle of the gatekeeper so are thickened and increase that food or milk have no opportunity to pass from a stomach in a small intestine. It usually occurs in the first six weeks after the birth.

Pylorostenosis reasons:

So far it is authentically not known what causes a thickening and expansion of muscles of the gatekeeper.
The pyloric stenosis arises more often at  boys, than at girls (85:15) and family cases of this pathology are, as a rule, noted.

Pylorostenosis symptoms:

1. Vomiting:
- Persistent vomiting the eaten food, as a rule, within 30 minutes after food.

For diagnosis information on feeding of the child, the nature of vomiting, loss of weight by the child can be required by the doctor. At a palpation of a stomach it is possible to find a thickening (gatekeeper) in a stomach.

If necessary carry out the following diagnostic tests:
- the food test - the child receives small food and then is observed within several hours;
- Ultrasonography of abdominal organs can indicate a thickening of muscles of the gatekeeper;
- a X-ray analysis with baric mix. At this research any obstacle in a way of a food lump, including a pyloric stenosis is visible;
- blood test - if vomiting was heavy and long, in blood symptoms of dehydration and loss of electrolytes can be found.

Treatment of the Pylorostenosis:

For treatment of a pyloric stenosis operation under  the name a pyloromyotomy is performed. The children's surgeon and the children's anesthesiologist in that case shall be a part of operational crew.

The pyloromyotomy can be executed by means of one of three methods:
- open operation – is made a small cut directly over the place where is the gatekeeper;
- umbilical approach - a section through a navel;
- laparoscopic operation – through three small  sections.  
At all types of operation the surgeon cuts the thickened and increased gatekeeper's muscle, as removes obstruction.

After operation it is necessary to watch a postoperative wound carefully. It is necessary to see a doctor if you noticed any symptoms of an infection:
- reddening around a wound increased;
- there were purulent discharges from a wound;
- temperature increased;
- there was a puffiness around a wound.
