Difficulty: EasyPediatric Gastrointestinal Disorders

Match each classic pediatric clinical presentation with the most likely underlying gastrointestinal diagnosis.

  • Episodic, crampy abdominal pain in a toddler accompanied by drawing the legs upward and passage of stool containing mucus and blood.Intussusception
  • Immediate, forceful vomiting after feeds in a hungry infant, associated with hypochloremic metabolic alkalosis.Infantile hypertrophic pyloric stenosis
  • Failure to pass stool within the first 48 hours of life in a term neonate, complicated by progressive abdominal distension.Hirschsprung disease
  • Episodic, painless lower gastrointestinal bleeding in a preschool-aged child with an otherwise normal physical examination.Meckel diverticulum

Answer

Episodic pain and bloody stool matches Intussusception; Forceful vomiting and alkalosis matches Infantile hypertrophic pyloric stenosis; Failure to pass meconium matches Hirschsprung disease; Painless lower GI bleeding matches Meckel diverticulum.
Each clinical vignette provides highly specific 'buzzwords' and pathophysiological clues that unequivocally map to a single classic pediatric GI disorder. Recognizing these hallmark features (e.g., currant jelly stool, non-bilious projectile emesis, delayed meconium, painless hematochezia) is essential for rapid diagnosis and appropriate management.

Step-by-Step Solution

1
Evaluate the toddler with episodic pain, leg drawing, and bloody/mucus stool.
Identify this as Intussusception.
The symptoms represent the classic presentation of bowel telescoping leading to ischemia and 'currant jelly' stool.
2
Evaluate the infant with forceful vomiting and hypochloremic metabolic alkalosis.
Identify this as Infantile hypertrophic pyloric stenosis.
Gastric outlet obstruction prevents food from entering the duodenum, causing severe non-bilious emesis and loss of stomach acid.
3
Evaluate the term neonate with delayed meconium passage and distension.
Identify this as Hirschsprung disease.
The absence of ganglion cells in the distal colon creates a functional obstruction, preventing the passage of the first stool within the normal 48-hour window.
4
Evaluate the preschooler with isolated, painless lower GI bleeding.
Identify this as Meckel diverticulum.
Ectopic gastric mucosa within the diverticulum secretes acid, ulcerating adjacent normal ileal mucosa and causing painless bleeding.
