Which term corresponds to the description 'Bowel telescoping in infants'?

• A. Pyloric Stenosis
• B. Febrile Seizure
• C. SIDS
• D. Intussusception

Answer: (D)

Intussusception is the invagination of one segment of bowel into the adjacent distal segment, producing a telescoping effect. In infants this condition classically presents with intermittent, severe colicky abdominal pain, the infant drawing up the legs during episodes, sometimes with vomiting and, as blood supply becomes compromised, currant jelly stools. A palpable sausage-shaped abdominal mass may be felt, and ultrasound typically shows a characteristic target or donut sign that confirms the diagnosis. It’s an emergency because obstruction and ischemia can progress if not treated. Management often begins with nonoperative reduction using an air (pneumatic) or hydrostatic enema under imaging guidance, with surgery reserved for cases that fail enema reduction or show perforation or peritonitis. The other options describe conditions that do not involve telescoping of bowel—pyloric stenosis causes projectile vomiting due to a thickened pylorus; febrile seizures are seizures linked to fever; SIDS is sudden infant death syndrome.
