Cornelia de Lange Syndrome (CdLS)

Gastrointestinal Manifestations, Complications & Management — Pediatric GI Quick Reference

Clinical Pearl: Behavioral escalation or irritability in CdLS often reflects GI pain (reflux, constipation, obstruction).

At-a-Glance Overview

Common GI Symptoms & Clinical Manifestations

Gastroesophageal Reflux Disease (GERD)

Feeding Difficulties & Dysphagia

Intestinal Malrotation

Volvulus (Emergency)

Other Anatomic GI Abnormalities

Eosinophilic Esophagitis (EoE)

Constipation

Aspiration & Oropharyngeal Dysphagia

Major Complications to Monitor

Complication Key Points
Esophagitis / Stricture Persistent symptoms or hematemesis → consider endoscopy.
Barrett’s Esophagus Recognized long-term complication of severe GERD.
Volvulus Bilious vomiting = emergency.
Aspiration Pneumonia Often subtle; requires coordinated GI + pulmonary care.
Growth Failure Use CdLS-specific growth charts when available.
Behavioral Dysregulation Often reflects GI pain rather than psychiatric cause.

Treatments & Management

Condition Treatment Approaches
GERD
  • PPIs (first-line), H2 blockers.
  • Upright positioning, thickened feeds.
  • Fundoplication for refractory GERD or aspiration.
Feeding Difficulties
  • High-calorie formulas, fortification.
  • Feeding therapy (OT/SLP).
  • G-tube for inadequate intake or unsafe swallow.
Malrotation / Volvulus
  • Ladd procedure for malrotation.
  • Emergency surgery for volvulus.
EoE
  • Elimination diets.
  • Swallowed topical steroids.
Constipation
  • Polyethylene glycol (first-line).
  • Stimulants or softeners as needed.
Aspiration
  • Swallow study to determine safe textures.
  • Thickened liquids, pacing, therapy.
  • G-tube if oral feeding unsafe.

Red Flags Requiring Urgent Evaluation

Immediate attention: These signs in CdLS require urgent ED or surgical evaluation.
