sis), which is a more common abdominal deformity in newborns, with most male babies and a male to female ratio of about 1

0: 1. Due to the difficulty of passing food, children's nutrition will be seriously impaired.

Cause death.

There is no satisfactory explanation for the cause of this disease so far, and it is currently recognized that it may be related to the pyloric muscle.

Dysgenesis or absence of plexus, resulting in poor relaxation of the pyloric sphincter, causing gastric pylorus

Muscle compensatory hypertrophy. Its pathological features are hypertrophy and hyperplasia of the pyloric sphincter.

Cartilage, shaped like an olive, has severely narrowed pyloric ducts, producing significant mechanical obstruction.

Clinical features of pyloric stenosis

More pyloric obstruction than at 2 or 3 weeks after birth: a. Nausea and vomiting, after eating

Occurs immediately or after 10 minutes. Vomiting is spouting and the discharge is bile-free.

It is a gallbladder. b. It can be seen that the peristaltic wave of the stomach moves from the lower left rib to the right and disappears to the right upper abdomen. c

A pyloric mass, in about 90% of cases, can be in the right upper abdomen (usually at the lower edge of the liver and the outer edge of the rectus abdominis muscle)

Between), can touch a 2 × 1cm size, clear edges, hard as cartilage is spindle-shaped, surface

A smooth lump on the face is best checked while the sick child is asleep or pumping. d. Barium meal check will

Barium is mixed in the milk, and the perspective of the post-eating shows that the lower end of the gastric expansion is conical and has strong and deep worms.

Dynamic wave, suddenly disappeared in the pylorus, rarely barium enters the duodenum, and barium passes through the pylorus

The cavity is slender and linear, and gastric emptying is slow. e. B-type ultrasonic detection, showing a low echo mass

(Substantially dark area), located on the inside of the gallbladder, in front of the right kidney and outside of the pancreatic head when scanning laterally;

It is located in the lower part of the gallbladder during the longitudinal scan. The mass is about 1cm in diameter, and there is a circular or star-shaped circle in the center.

General treatment and prevention of pyloric stenosis

Those who have not improved after sedation, antispasmodics and correction of water and electrolyte disorders should be operated on

treatment. Mostly use a right upper abdominal transverse incision, and open the pyloric circular muscle longitudinally after laparotomy without cutting

Break the mucous membrane, and then separate the severed muscle ring to make the mucosa protrude from the wound margin, thereby expanding the

At the door, remove the obstruction. Note that the distal end of the incision on the mass should not exceed the duodenum during operation.

Do not cut to cause duodenal fistula.
