What is Pyloric Stenosis

Pyloric stenosis, or hypertrophic pyloric stenosis (HPS), affects neonates by narrowing and thickening the pylorus, the muscular opening between the stomach and the small intestine. Gastric outlet obstruction is caused by a constriction, or stenosis, that stops food from passing from the stomach to the small intestine. Although the exact cause is unknown, it is assumed to be a complicated disorder caused by genetic and environmental factors. Males are nearly four times more likely than females to suffer pyloric stenosis, suggesting a gender-based threshold for its manifestation.

The thicker muscle, known as hypertrophy, interferes with the pyloric valve, which controls the passage of food. Symptoms in affected babies include projectile vomiting, malnutrition, dehydration, weight loss, and insatiable hunger. When a child is six months old, the issue is generally visible, and surgery is required to remove the obstruction.

It’s difficult to understand how pyloric stenosis is inherited because the gender of the affected child and the next sibling influences the risk of recurrence. Early detection and surgical intervention ensure a good prognosis for newborns suffering from this condition.

Symptoms of Pyloric Stenosis

Pyloric stenosis symptoms are unusual in newborns older than three months, and they often develop three to six weeks after delivery. The symptoms listed below are symptomatic of the condition:

  • Projectile Vomiting– After feeding, vomiting occurs regularly with force, ejecting formula or milk several feet away. Typically, it starts slowly and gets worse over time bile is present, and the vomit can seem clear or curdled.
  • persistent hunger- Despite having vomited, affected babies typically show signs of hunger and a desire to feed again soon after.
  • Abdominal wavelike movements– After feeding but before vomiting, the baby’s stomach muscles may create apparent spasms or ripples as they try to push the food through the obstruction.
  • Dehydration– Symptoms include less wet diapers, dry lips and tongue, sluggishness, and non-tearful weeping. Jaundice, or yellowing of the skin and eyes, can occur in severe cases.
  • modifications to the stool- Because so little food is going to the intestines, newborns may have constipation. This can lead to the loss or inability to gain weight
  • Abdominal pain and irritation because of stomach cramps can make the babies act fussy or appear uncomfortable.

Sometimes, a palpable mass resembling a “sausage” can be felt in the baby’s abdomen. Parents should distinguish between severe vomiting, which indicates a major condition, and regular spit-up. If these symptoms appear, it is critical to consult a doctor immediately because pyloric stenosis can cause severe malnutrition and dehydration if not treated.

Causes of Pyloric Stenosis

Pyloric stenosis is a complex condition resulting from a combination of environmental and inherited causes. These factors interact together to contribute to its development, while the exact cause is unknown. Pyloric stenosis, which is usually nonexistent at birth, develops over the first few weeks of life.

This condition occurs nearly four times more frequently in men than in women, demonstrating a gender-related threshold for manifestation. Multifactorial inheritance also impacts recurrence risks; the gender of the first sick child and the second child impacts the likelihood that the illness will reoccur in the next child.

Treatment

Although initial steps are focused on stabilising the infant’s health, surgical surgery is the primary treatment for pyloric stenosis. Here’s a detailed explanation:

Preparation and diagnosis before surgery

  • Blood tests are used to diagnose electrolyte imbalances and dehydration. Intravenous (IV) fluids are used to treat dehydration by replenishing lost fluids and correcting any mineral deficits.
  • Pre-operative Instructions are to reduce the risk of aspiration during anaesthesia, the newborn should not be fed (milk or formula) for at least six hours before surgery.

Surgical Procedure: Pyloromyotomy

Pyloromyotomy is the definitive treatment for pyloric stenosis and almost always resolves the condition permanently.

Laparoscopic Methodology

The infant receives general anaesthesia. To reach the pylorus, a small incision is made above or near the belly button. To provide a broader passageway for food to enter the intestines, the surgeon delicately trims the thicker outer muscle of the pylorus while leaving the inner layers intact.

Often, the first option is minimally invasive laparoscopic surgery. A camera and surgical equipment are introduced through tiny incisions, and carbon dioxide gas is injected into the stomach to improve vision. The approach is less invasive than open surgery, requiring only two to three incisions.

In very rare occasions that the laparoscopic method is not possible, open surgery is performed. 

Conclusion

Although it can be alarming, pyloric stenosis is treatable and has a favourable prognosis if detected early. Even though the illness can be highly unpleasant and result in malnutrition and dehydration, it can be effectively treated with immediate medical attention, typically with pyloromyotomy surgery. Laparoscopy and other less invasive surgical techniques have reduced recovery periods and scarring.

Parents can seek timely care and ensure their newborn receives the necessary therapy by recognising the signs, which include dehydration, projectile vomiting, and persistent hunger. When properly cared for, the majority of babies thrive and develop normally. If you suspect your unborn child has it, consult your doctor straight away for a thorough evaluation and guidance.

Frequently asked questions

1.How long does pyloric stenosis surgery take?

Usually, the surgery takes less than an hour. 

2.Can pyloric stenosis recur after surgery?

It is extremely rare for it to recur, the surgery is considered a permanent cure. 

3.Is pyloric stenosis preventable?

Since the cause of pyloric stenosis is not known, preventing it is not easy. It is easiest to catch it early and get treatment.

4.Does pyloric stenosis affect long-term health?

No, once it is cured the baby will grow to live a normal life without having lasting effects.
