Bowel ultrasound (US) is a cost-effective, well-tolerated, non-invasive and readily available tool for the management of patients with inflammatory bowel disease (IBD), including UC, in ...

Megaduodenum due to its duodenal ganglionitis is an unusual condition, Megaduodenum's similarity to megacolon and megaesophagus diseases can better explain the most plausible causes of it.
