A. Mechanical• Pyloric stenosis• Intestinal
atresia, stenosis• Malrotation• Volvulus• Abdominal wall
defects• Anorectal
anomalies• Incarcerated
hernia• Intussusception
B. Functional • Necrotizing
enterocolitis• Hirschsprung’s

• Malrotation with midgut volvulus
• Intussusception (3months to 3years)
• Incarcerated hernia
• Intussusception
• Incarcerated hernia
• Perforated appendicitis
• IBD
• Intrinsic lesions such as polyps, masses or Merkel’s diverticulum
• Extrinsic compression from incarcerated hernia, perforated appendicitis or post-operative adhesions

Intestinal atresia• Incidence 1:2700 births

Malrotation and volvulus • 1:500 births (US)
• Intestinal non rotation or incomplete rotation around the superior mesenteric artery
• Malrotation is often not evident until the baby experiences a twisting of the intestine known as a volvulus
• In the hands of experienced ultrasonographers, ultrasonography has been shown to be very sensitive (approximately 100%) in detecting neonatal malrotation

In this upper GI series with abnormal results, the duodenum does not cross the midline, and the small bowel is present only in the right side of the abdomen
These 2 lower GI series show the cecum (arrows) in the right upper quadrant, indicative of malrotation

Intussuseption • Telescoping of one portion of intestine to another
• 1:2000 births (US)
• Bloody jelly stool
• Nonoperative reduction with a therapeutic enema/air. Its contraindications are peritonitis and any evidence of perforation on plain x ray

General treatment• Fluid and electrolyte replacement
• NBM and NG tube decompression
• Early surgical consultation
• Indications for emergeny laparotomy• Malrotation with or without midgut volvulus• Pneumoperitoneum• Irreducible intussusception• Peritonitis
