Diverticulitis of small intestine (ICD-11 DC70, small bowel diverticulitis) is inflammation of small-intestine diverticula, mainly jejunal or duodenal, causing bleeding, perforation, abscess, or obstruction, diagnosed by CT.
Diverticulosis
Diverticulosis of large intestine (ICD-11 DC81, colonic diverticulosis): multiple pouches (diverticula) herniating through the colon wall, mostly sigmoid; over 30% of US adults 50-59 affected, usually asymptomatic, under 5% develop diverticulitis.

Diverticulum of small intestine
Diverticulum of small intestine (small bowel diverticulum, SBD): an outpouching of the small intestinal wall; Meckel's is the only true congenital form, acquired false diverticula affect duodenum, jejunum, ileum, causing bleeding, diverticulitis, perforation, obstruction.
