ICD-11 Diverticular disease of small intestine

Diverticula can occur anywhere in the small intestine, but they are most common in the jejunum. They represent herniations through the mesenteric side of the bowel and are usually acquired. This refers to the clinical entity characterised by the presence of sac-like outpocketings of the intestinal mucosa and submucosa through weak points of the muscle layer of the small intestine. This contains both diverticulitis and diverticulosis.
