Study Notes
Pyloric Stenosis
Infantile Pyloric Stenosis
- A congenital condition that affects infants, typically between 2-4 weeks old
- Caused by hypertrophy of the pyloric muscle, leading to narrowing of the pyloric canal
- Boys are more commonly affected than girls (4:1 ratio)
Symptoms and Diagnosis
- Common symptoms:
- Vomiting (projectile, non-bilious)
- Poor feeding
- Weight loss or failure to gain weight
- Visible peristalsis
- Diagnostic methods:
- Physical examination (palpable olive-shaped mass in the upper abdomen)
- Ultrasound (enlarged pyloric muscle and pyloric canal narrowing)
- Upper GI series (delayed gastric emptying and pyloric stenosis)
Treatment Options
- Surgical treatment is the standard of care
- Laparoscopic pyloromyotomy (see below)
- Open pyloromyotomy (alternative to laparoscopic approach)
Laparoscopic Pyloromyotomy
- Minimally invasive surgical technique
- Involves making small incisions and using a laparoscope to visualize the pylorus
- The pyloric muscle is split, releasing the narrowing and allowing for normal gastric emptying
Postoperative Care
- Infants are typically fed within a few hours after surgery
- Monitor for vomiting, fever, and wound infection
- Pain management with acetaminophen or ibuprofen
- Follow-up with pediatrician and surgeon to ensure proper healing and weight gain
