To achieve more thorough understanding of the clinico-imaging spectrum of bowel intussusception of various aetiologies. To become familiar with optimal techniques and attain confidence in use of ultrasound for diagnostic evaluation.

There is a growing recognition that intussusception in adult population is not as rare as we previously believed. Moreover, accumulated experience in cross sectional imaging, including our own suggests that the majority of intussusceptions detected in adults are due to enteroenteric transient intussusceptions without lead point, which are self-limiting [1-5]. Many of these are incidental but some are associated with underlying conditions such as coeliac disease and Crohn’s disease. The radiologist is invariably the first to suggest the diagnosis because clinical presentation is nonspecific. When...

Intussusception = prolapse (telescoping) of a bowel loop (entering segment or intussusceptum) with its mesentery into the lumen of contiguous distal bowel segment (receiving segment or intussuscipiens) (Fig.1). Any lesion involving bowel wall can potentially serve as a mechanical lead point pulled by peristalsis. Many conditions that alter bowel wall tone and peristalsis (ie. celiac disease, diarrheal diseases, diabetes mellitus) can unbalance peristaltic forces and potentially precipitate intussusception. Transient intussusception may be a physiological phenomenon of no significance, particularly in proximal small bowel where peristaltic...

Following the methodical approach outlined in this exhibit will enable the viewer to hasten the route to success in this area of imaging.
