Difficulty: Very hardPediatric Gastrointestinal Disorders

Match each pediatric gastrointestinal emergency clinical presentation with its most appropriate definitive surgical management.

  • A 3-day-old term infant presents with sudden-onset bilious emesis and hemodynamic instability. Upper GI series shows a 'corkscrew' appearance of the proximal small bowel.Counterclockwise detorsion, division of mesenteric bands, widening of mesenteric base, and appendectomy
  • A premature neonate (26 weeks gestation) develops lethargy, thrombocytopenia, and bloody stools. Abdominal radiograph shows portal venous gas and pneumoperitoneum.Primary peritoneal drainage or exploratory laparotomy with necrotic bowel resection
  • An 8-month-old boy presents with lethargy and intermittent severe abdominal pain. Ultrasound shows a target sign, but fluoroscopic air enema is unsuccessful at resolving the lesion.Operative manual reduction; if unsuccessful or bowel is necrotic, segmental resection with primary anastomosis
  • A newborn with Down syndrome presents with bilious vomiting on the first day of life. Radiographs demonstrate a dilated stomach and proximal duodenum with an absence of distal bowel gas.Surgical bypass via duodenoduodenostomy or duodenojejunostomy
  • A 3-year-old girl is evaluated for severe symptomatic anemia and painless dark red rectal bleeding. Technetium-99m pertechnetate scan demonstrates focal ectopic activity.Wedge resection of the anomaly or segmental ileal resection

Answer

Each pediatric GI emergency is accurately matched with its specific surgical intervention based on its unique anatomical and pathophysiological requirements.
Each pediatric gastrointestinal emergency requires a specific surgical approach tailored to its underlying pathophysiology. Malrotation requires detorsion and widening of the mesentery (Ladd procedure). Perforated NEC requires resection of necrotic tissue or drainage. Refractory intussusception requires manual reduction or resection. Duodenal atresia requires surgical bypass. Meckel diverticulum requires resection of the ectopic gastric mucosa.

Step-by-Step Solution

1
Identify the underlying pathology for the first patient.
The corkscrew appearance on upper GI series in an infant with bilious emesis indicates midgut volvulus due to malrotation.
Recognizing the diagnostic imaging pattern is essential to determine the specific surgical procedure required.
2
Determine the surgical intervention for malrotation with volvulus.
The correct management is the Ladd procedure (counterclockwise detorsion, division of bands, appendectomy).
This procedure untwists the bowel and prevents future catastrophic recurrent volvulus.
3
Diagnose the premature infant with pneumoperitoneum and determine management.
The diagnosis is perforated necrotizing enterocolitis (NEC), requiring laparotomy with bowel resection or primary peritoneal drainage.
Pneumoperitoneum is an absolute indication for surgical intervention in NEC.
4
Identify the next step for intussusception refractory to air enema.
Operative manual reduction or segmental resection is required.
Failure of non-operative reduction means mechanical surgical reduction is necessary to prevent bowel ischemia.
5
Diagnose the newborn with a double bubble sign and determine surgery.
The diagnosis is duodenal atresia, managed with duodenoduodenostomy.
The congenital obstruction must be surgically bypassed to allow enteral feeding.
6
Match the bleeding child with positive Meckel scan to treatment.
Meckel diverticulum is treated with wedge or segmental resection.
The bleeding ectopic gastric mucosa must be completely excised.

Key Concept

Surgical management of pediatric gastrointestinal emergencies requires recognizing specific clinical and radiologic patterns to select the exact corrective procedure.
