Meconium ileus features
Earliest manifestation of cystic fibrosis. Thick meconium plugs can't pass through ileocecal valve. Multiple dilated loops of small intestine. Bubbly intestinal contents represent retained meconium. Often treated with water-soluble contrast enema.
Intrauterine intestinal perforation from bowel obstruction or ischemia. Extruded meconium mayh calcify. Scattered amorphous or curvilinear calcifications throughout peritoneum. Snowstorm ultrasound appearance.
Meconium plug syndrome also known as small left colon syndrome of distal colon. Normal to dilated proximal colon filled with meconium. Empty distal descending colon. More common in normal large infants and infants of diabetic mothers. Often treated with rectal stimulation or saline enemas.
Transient functional immaturity and abnormal peristalsis
Megacystis-microcolon-hypoperistalsis (MMH) syndrome tract. Almost exclusively in girls. Insufficient abdominal muscles. Very large dysfunctional bladder. Bladder exstrophy may occur: Widened pubic symphysis. Splaying of pelvic bones. Decreased peristalsis leads to poor evacuation of colon.
