How are the diagnosis of diverticulitis and diverticulosis made?

If suspected, the diagnosis of diverticular disease can be confirmed by a variety of tests. Barium X-rays (barium enemas) can be performed to visualize the colon. Diverticula are seen as barium filled pouches protruding from the colon wall.

Direct visualization of the inside of the colon and the openings of the diverticula can be done with flexible tubes inserted through the rectum and advanced into the colon. Either short tubes (sigmoidoscopes) or longer tubes (colonoscopes) may be used to assist in the diagnosis and to exclude other diseases that can mimic diverticular disease.

In patients suspected of having diverticulitis causing persistent pain, tenderness, and fever; ultrasound and computerized tomography (CT) examinations of the abdomen and pelvis can be done to detect inflammation of the tissues surrounding the ruptured diverticulum or collections of pus.
