HPS is a surgical emergency, and is the most common cause of intestinal obstruction in infants. For unknown reasons the pylorus hypertrophies after birth and causes progressive gastric outlet obstruction. The incidence is approximately 2–5 per 1,000 live births; the risk is four times higher in boys than girls.
Does pyloric stenosis always require surgery?
Pyloric stenosis is always treated with surgery, which almost always cures the condition permanently. The operation, called a pyloromyotomy, divides the thickened outer muscle, while leaving the internal layers of the pylorus intact.
Can pyloric stenosis cause death?
Death from infantile hypertrophic pyloric stenosis is rare and unexpected. The reported mortality rate is very low and usually results from delays in diagnosis with eventual dehydration and shock.
What happens if pyloric stenosis is left untreated?
If left untreated, hypertrophic pyloric stenosis can cause: Dehydration. Electrolyte imbalance. Lethargy.
What are the long term effects of pyloric stenosis?
There are no long-term effects. Recurrence of HPS is extremely rare with only a one percent chance. The rare baby with recurrent pyloric stenosis is still expected to have a normal gastro-intestinal tract long term, but may need additional surgery or nutritional therapy to recover.
Can babies with pyloric stenosis still gain weight?
Babies with pyloric stenosis usually have fewer, smaller stools because little or no food is reaching the intestines. Constipation or stools that have mucus in them may also be symptoms.

A small incision is made over the abdomen or belly. The surgeon will open the thickened stomach muscle so that food can pass out of the stomach more easily. The surgery usually takes less than 1 hour, and your baby will be in the recovery room for about another hour.
Can pyloric stenosis cause reflux?
Diagnosing pyloric stenosis
Pyloric stenosis can be confused with reflux (frequent spit-up) or gastroesophageal reflux disease (GERD), a condition in which the contents of the stomach come back up. GERD can also cause irritability and poor weight gain.
What are the symptoms of pyloric stenosis in adults?

Is pyloric stenosis painful?
Symptoms and Causes

Can a baby outgrow pyloric stenosis?
Long-term outlook. Pyloric stenosis is unlikely to reoccur. Babies who have undergone surgery for pyloric stenosis should have no long-term effects from it.
Why is pyloric stenosis more common in males?
WHAT’S KNOWN ON THIS SUBJECT: Infantile hypertrophic pyloric stenosis is 5 times more common in male infants. The male hormone testosterone is known to induce muscle hypertrophy, and the testosterone levels are several-fold higher in male infants than female infants.
Can pyloric stenosis cause GERD in adults?
It can be a problem of the pyloric valve or the “doorway” that separates the stomach contents from those of the small intestine. When the pyloric valve doesn’t work properly, food stays in the stomach, and symptoms such as bloating, nausea, vomiting, reflux can occur.
What does it mean when a baby’s stomach is tight?

If your child’s abdomen feels swollen and hard, and if she has not had a bowel movement for more than one or two days or is vomiting, call your pediatrician. Most likely the problem is due to gas or constipation, but it also could signal a more serious intestinal problem.
Can pyloric stenosis be missed on ultrasound?
If the ultrasonographic findings are negative, perform a UGI study to confirm or rule out other pathology. Ultrasonography, although reliable for diagnosing hypertrophic pyloric stenosis, may miss malrotation, which is the most serious cause of vomiting in infants.
What does pyloric stenosis vomit look like?
The most common symptoms noted in a baby with pyloric stenosis is forceful, projectile vomiting. This kind of vomiting is different from a “wet burp” that a baby may have at the end of a feeding. Large amounts of breast milk or formula are vomited, and may go several feet across a room.

Can you live without a pyloric sphincter?
Gastrectomies that result in removal of the pylorus/plyroic valve can allow food to move into the upper part of the small intestine (the duodenum) very rapidly. The absence of the pyloric valve combined with removal of the stomach (resulting in no “storage area ” for digestion) can cause “dumping syndrome”.
