Dr. William Byars answered:

How do you test for metabolic alkalosis? If this is confirmed how is it treated?

Treat the cause

The most certain way to test for alkalosis (or acidosis) is with an arterial blood gas test. If the arterial pH is abnormally high, there is alkalosis. M. A. typically shows an elevated serum CO2 level, because of increased bicarbonate. The treatment depends on the cause of M.A. Repeated vomiting causes M.A. because of loss of HCl (acid) from the stomach. You treat the cause of vomiting.

What is the result of metabolic acidosis if pyloric stenosis?

Bowel obstruction

Open-uri20121007-19187-i6m9g2
then vomiting, dehydration and loss of electrolytes. Gastric contents lost as vomit include acids, leading to a metabolic alkalosis (a 'contraction' alkalosis) with hypokalemia (low potassium), The baby needs to be admitted to a hospital, have intravenous fluids, a surgical consult and surgical repair of the pylorus to relieve the stenosis. It can be performed open or laprascopic.

What are the symptoms of Pyloric Stenosis?

Projectile vomit

Laparoscopic_surgery
1-2 month old who starts to vomit after meals. It progresses. Vomit after eating gets worse and more forceful. Sometimes more common in first born males. Ultrasound is diagnostic. Surgery only after the fluid balance is restored. Hope this helps. Laparoscopic surgery is common for this operation.

Dr. Joseph Iocono answered:

What problems can result from a late diagnosis of pyloric stenosis in infants?

Severe dehydration

Stricture
If a baby has delayed diagnosis of pyloric stenosis the baby may have profound dehydration and metabolic alkalosis. Thankfully with directed rehydration over hours to days this can be corrected and then the baby can undergo surgery to repair the problem

Dr. Faisal Qureshi answered:

Are there any important lab tests that will help diagnose pyloric stenosis?

No

Ultrasound
Although lab tests can help with the diagnosis, the actual diagnosis is made on history, physical exam and nowadays on ultrasound. Lab tests help determine how severely dehydrated the child is.

What is pyloric stenosis?

Stomach exit blockag

Stomach_stricture
In a baby with hypertrophic pyloric stenosis (HPS), the circular pyloric muscle fibers which regulate the emptying of the stomach become swollen ("muscle-bound") usually between 2 and 8 weeks' age. The pyloric channel becomes blocked, and fluid cannot exit the stomach. The baby has progressive projectile nonbilious vomiting which can cause dehydration and weight loss if uncorrected.

What causes pyloric stenosis?

Ulcer disease

Stricture
It happens in neonates in the first month. In adults, it is usually a result of ulcer forming and healing cycle repeated over time. This scarring causes the stomach opening to narrow over time.

What are the pyloric stenosis risk factors?

Minimal

Stricture
Pyloric stenosis is seen in babies from 2-6 or 7 weeks of age. There is often a family history of HPS. Over time, once surgically corrected, the issue is resolved.

Could pyloric stenosis 'come back'?

Ususally not

Stricture
I have seen one case of recurrent hypertrophic pyloric stenosis in forty years. I do not know whether initial surgery was insufficient or exact reason for this occurrence.
