Sample text

12 Midgut volvulus in a 16-day-old male infant with bilious vomiting. (a) Upper gastrointestinal study, anteroposterior projection. Radiograph demonstrates the corkscrew configuration of the duodenum and proximal jejunum. (b) Lateral projection. The spiral or corkscrew appearance of the duodenum and jejunum is again shown (arrows). The anterior course of the distal duodenum is demonstrated. (c) Midgut volvulus (arrows) without ischemia was found at surgery except in those with evidence of complete duodenal obstruction in the plain radiograph or in critically ill infants.

However, the sonographic transition zone does not correlate with enema findings or pathology making it an unreliable finding. The radiologic diagnosis of total colonic aganglionosis is much more difficult. Findings may include a normal barium enema, a short colon of normal caliber, a microcolon, rounding of the colonic flexures, or a transition zone in the ileum (Fig. 34). Clinical suspicion should be heightened in patients presenting with clear signs and symptoms of distal obstruction, in whom the contrast enema does not demonstrate a specific cause (Hayakawa et al.

Ultrashort segment disease (with aganglionosis essentially limited to the region of the internal sphincter) and aganglionosis involving the entire alimentary tract are very rare presentations (Laughlin et al. 2012). In children with Hirschsprung disease, the absence of ganglion cells results in the failure of the distal intestine to relax normally; peristaltic waves do not pass through the aganglionic segment, and there is no normal defecation leading to a functional obstruction. The aganglionic segment remains unexpanded, and the proximal colon becomes distended and hypertrophied.
