Pyloric stenosis (pylorus narrowing)

The pyloric stenosis is an evacuation disturbance of the stomach happening frequent relatively. About 0.3 per cent of the newborn childs are affected by it. The pylorus narrow part of the second till fourth life week typically appears. The characteristic symptom is a flood like vomiting primarily after the meals. The causes are an enlargement (hypertrophy) and cramp (spasm) of the ring musculature of the pylorus (pylorus) and the pylorus near stomach portions. One also therefore talks about a spastic hypertrophic pyloric stenosis. Common synonymous ones are also pylorospasm or pyloric hypertrophy. The pylorus completes the stomach against the duodenum (duodenum). Only if the pylorus opens, the chyme can be further transported into the intestine. At the pyloric stenosis this doesn't happen or only very much restrictedly.

The exact causes of the pyloric stenosis aren't known. Genetic causes are discussed since the illness appears familially in large numbers. 5 times, boys are concerned more frequently than girl.

The clinical picture appears in the following way:

The intensity (increases) usually in the third life week break the children in the ray or arch open, at first approximately half an hour after it eat then however always frequent. Never gall smells acidically and contains, however, stinging, the broken open with pleasure. After the vomiting the children drink avariciously. You, however, cannot keep it at itself. By the permanent vomiting they aren't provided with nutrients sufficiently and many lose fluid. Since also no-one or very little nutrition pap reaches the intestine, they have rarely and very little bowel movement. Dries her out as a result of the fluid loss, it comes to prospering disturbances and weight loss. The children have a senile, forced till worried facial expression. A pyloric stenosis can untreatedly lead to the coma (coma pyloricum) and at long last to the death.

Therefore go with your child to the physician immediately if you notice symptoms for a pylorus narrowing at it! The prognosis is very good at medical treatment at full term. The children recover completely within less weeks again. It doesn't come to relapses.

The physician makes the diagnosis as follows:

  • At first an exact interview is carried out for the disease history (anamnesis).
  • A physical examination follows. You pay attention on visible stomach motions, for example. Perhaps the attending doctor also feels an olive great tumescence in the abdomen on the right. Breath disturbances and reduced consciousnesses are ascertainable in difficult cases.
  • With a painless Sonografie (ultrasound scan) of the abdomen the diagnosis is safeguarded.
  • A roentgen contrast photo of the gastrointestinal tract is still made possible in cases of doubt.
  • With the help of blood tests one can state shifts in the water and mineral household and in the acid-base balance.
Since the disease conditional water and electrolyte loss can have life-threatening consequences for the children concerned, at first infusions are laid out in the compensation.

It two therapy ways then can be taken:

Since the appearances of the pyloric stenosis disappear spontaneously after the 3rd life month, a conservative medical treatment, this means a medical treatment without operation, tempted can be in very light cases. The children are laid down with an increased upper part of the body and receive only small but many meals. You get muscle easing medicines (spasmolytics).

It can last for weeks, however, until this method of treatment beats. It isn't always successful either. It can be that you must nevertheless have an operation. Perhaps a recovery of the infant only is delayed.

Nowadays the advantage is given to the operative medical treatment. Primarily at difficult cases a pylorotomy is carried out after Weber and Ramstedt as quickly as possible. The complete pylorus musculature is by separated lengthways and the stomach exit stretched so. You can start with an oral fluid supply about twelve hours after the operation. The children recover after the operation in one to three weeks.
