Jejunal diverticula are usually multiple and localized to the proximal jejunum. Jejunoileal diverticula may be composed of mucosa and submucosa only, or of all layers of the jejunal wall. The cause of jejunoileal diverticula is unclear, but intestinal dyskinesia and high intraluminal pressure have been implicated in the pathogenesis.

The most frequent complications are:

• complete small bowel obstruction due to volvulus.
• development of an abscess
• diverticular perforation
• gastrointestinal bleeding
