Congenital antral web
Congenital antral web (prepyloric diaphragm, gastric antral web): a rare 2–4 mm mucosal membrane 1–7 cm proximal to the pylorus causing gastric outlet obstruction, presenting with non-bilious vomiting and failure to thrive, treated surgically or by endoscopic balloon dilation.
Congenital esophageal diverticulum
Congenital esophageal diverticulum (congenital esophageal pouch, ORPHA:91358, ICD-10 Q39.6) is a rare non-syndromic birth malformation: a false esophageal outpouching, usually upper posterior, causing dysphagia, regurgitation, cough, or respiratory distress; treated by excision.
Congenital esophageal stenosis
Congenital esophageal stenosis (CES), a rare intrinsic narrowing of the esophagus present at birth (1 in 25,000-50,000 births), occurs as tracheobronchial remnants, fibromuscular stenosis, or membranous web, treated by dilatation or resection.
Congenital hiatus hernia
Congenital hiatus hernia (congenital hiatal hernia, ICD-11 LB13.1): herniation of abdominal contents, usually the stomach, through the esophageal hiatus into the mediastinum from disordered diaphragm development; rare in children, treated with repair plus fundoplication.
Pyloric stenosis
Congenital (infantile) hypertrophic pyloric stenosis, IHPS: pyloric muscle hypertrophy narrowing the gastric outlet, causing projectile non-bilious vomiting at 2-6 weeks; treated by Ramstedt pyloromyotomy after fluid correction.
