Expert statements from the recordings in this collection.
Pyloric Stenosis
Pyloric stenosis is hypertrophy and hyperplasia of the inner circular layer with associated mucosal hypertrophy
Bhargava Muliudi0:31
Pyloric stenosis leads to gastric outlet obstruction in infants between 2 to 10 weeks of age
Bhargava Muliudi0:37
Pyloric stenosis is more common in males
Bhargava Muliudi0:46
There is increased risk for first born infants with a positive family history
Bhargava Muliudi0:49
Patients with pyloric stenosis typically present with non-bilious vomiting, usually seen between 2 to 10 weeks of life
Bhargava Muliudi1:04
Infants with pyloric stenosis are otherwise well appearing and hungry after vomiting
Bhargava Muliudi1:12
Emesis in pyloric stenosis will progress until it is projectile
Bhargava Muliudi1:16
Hyperbilirubinemia can occur in up to 14% of patients with pyloric stenosis due to downregulation of hepatic enzymes associated with starvation
Bhargava Muliudi1:24
Bilious emesis should always be worked up to rule out intestinal malrotation with midgut volvulus
Ultrasound is the gold standard for diagnosing pyloric stenosis
Bhargava Muliudi2:50
Pyloric stenosis is diagnosed on ultrasound when pyloric muscle is 3 millimeters thick and 14 millimeters long or greater
Bhargava Muliudi2:55
The classic electrolyte abnormality in pyloric stenosis is hypochloremic, hypokalemic, metabolic alkalosis
Bhargava Muliudi3:19
Prolonged gastric outlet obstruction leads to persistent vomiting and loss of hydrochloric acid, which leads to hypochloremia and loss of protons leading to metabolic alkalosis
Bhargava Muliudi3:29
The kidneys compensate for dehydration by increasing the activity of the sodium potassium pump to retain fluid, leading to urinary excretion of potassium to preserve sodium and water
Bhargava Muliudi3:41
In later stages of pyloric stenosis, excretion of protons leads to paradoxical aciduria, which further worsens metabolic alkalosis
Bhargava Muliudi3:56
In the US, pyloromyotomy is the standard of care for pyloric stenosis
In some countries, atropine is used as a non-surgical option for pyloric stenosis, with a success rate of about 60 to 90%
Bhargava Muliudi4:22
Cincinnati Children's follows a resuscitation protocol published by the Children's Mercy Group in Kansas City for pyloric stenosis
If chloride is less than 85, give 3 boluses separated by an hour and then recheck labs
If chloride is between 85 and 97, give two boluses
If chloride is greater than 97, give 1 bolus
If bicarbonate is greater than 40, give 3 boluses
If bicarbonate is greater than or equal to 33, give 2 boluses
Prior to going to the operating room, serum chloride must be corrected to greater than 100 and bicarbonate to less than 30
The proximal edge of the pylorus can be easily identified as the antrum transitions to a thick pylorus
Bhargava Muliudi7:00
The distal extent of the pyloromyotomy is generally to the crossing vein of Mayo or the white line, which marks the pyloroduodenal junction
Bhargava Muliudi7:07
After the pyloromyotomy is completed, the submucosa should bulge into the myotomy site
Bhargava Muliudi8:18
After adequate pyloromyotomy, each side of the pylorus should move independently
Bhargava Muliudi8:25
Complications from pyloromyotomy include incomplete myotomy, mucosal perforation, aspiration, wound infection, and incisional hernias
Bhargava Muliudi8:42
There is a slight increased risk of incomplete myotomy and perforation with a laparoscopic approach, but the overall low incidence of complications decreases the clinical significance of the differences between the two approaches
