Pyloric stenosis is a condition in which the opening between the stomach and small intestine thickens. This condition can lead to severe vomiting, dehydration, and weight loss. It is most commonly seen in infants.
Signs and Symptoms[edit]
The primary symptom of pyloric stenosis is projectile vomiting, which typically occurs after feeding. Other symptoms may include:
- Dehydration
- Weight loss
- Constant hunger
- Stomach contractions
Causes[edit]
The exact cause of pyloric stenosis is unknown, but it is believed to involve a combination of genetic and environmental factors. It is more common in males than females and tends to run in families.
Diagnosis[edit]
Diagnosis of pyloric stenosis is typically made through a combination of physical examination and imaging studies. An ultrasound is often used to confirm the diagnosis by showing the thickened pylorus.
Treatment[edit]
The standard treatment for pyloric stenosis is a surgical procedure called pyloromyotomy. This procedure involves splitting the muscle of the pylorus to relieve the obstruction.
Surgical Procedure[edit]
The pyloromyotomy can be performed as an open surgery or laparoscopically. The laparoscopic approach is less invasive and involves smaller incisions.
Prognosis[edit]
With appropriate surgical treatment, the prognosis for infants with pyloric stenosis is excellent. Most infants recover quickly and have no long-term complications.
