title: Intestinal Ultrasound in Rare Gastrointestinal Diseases, Update, Part 2.
abstract: Intestinal ultrasound has become an established and valid diagnostic method for inflammatory bowel disease, diverticulitis, appendicitis, bowel obstruction, perforation and intussusception. However, little is known about sonographic findings in other rarer intestinal diseases. Ultrasound may display the transformation of the intestinal wall from a normal to a pathological state both in inflammatory and neoplastic disease. Besides demonstrating the transmural aspect, it also shows the mesenteric reaction as well as complications such as fistula, abscesses, stenosis, or ileus. Furthermore, in some diseases intestinal ultrasound may serve as a diagnostic clue if typical patterns of the bowel wall and impaired peristalsis can be demonstrated. This may lead to an important reduction of invasive and expensive (follow-up) procedures. The information gained by ultrasound regarding intestinal disease, however, is as important and valid as e. g. in case of focal lesions of the liver. Serving as tertiary referral centers for a broad spectrum of intestinal diseases, we therefore report some aspects of ultrasound in patients with less often recognized diseases. The article is divided into two parts, the first focusing on examination techniques, infectious diseases and celiac sprue and the second on hereditary, vascular and neoplastic diseases and varia.
