CT scan showing extensive diverticulosis of the sigmoid colon Diverticular disease Whole slide of a transverse section of the left colon with diverticulosis. Diverticulosis is defined by the presence of multiple pouches (diverticula) in the colon. [22] In people without symptoms, these are usually found incidentally during other investigations.
In some cases, the affected part of the colon adheres to the bladder or other organs in the pelvic cavity, causing a fistula, or creating an abnormal connection between an organ and adjacent structure or another organ (in the case of diverticulitis, the colon, and an adjacent organ). Related pathologies may include: [12] Bowel obstruction ...
Acute diverticulitis is thought to arise from either trauma or lack of blood flow to the existing diverticulum in the colon. The traumatic theory proposes that a fecalith, which is a hardened fecal matter, becomes trapped in a diverticulum, leading to colonic mucosa abrasion and local inflammation.
Fecal calprotectin, a marker of colon inflammation, may be elevated. Computed tomography of the abdomen is not routinely necessary, but may show thickening or inflammation in the distal colon (sigmoid colon) with associated diverticulosis. Treatment may consist of antibiotics, aminosalicylates (mesalamine), or prednisone. In rare cases, surgery ...
Spaces between the circular bands of taeniae are weak points in the bowel, and are the sites of diverticulosis. Most diverticulosis occur in the sigmoid colon as it is the segment with the highest intraluminal pressure. Diverticulosis does not occur in the rectum as the tenia coli become a continuous
Diverticula, diverticulitis, diverticulosis video Diverticula, or a single diverticulum, is this pouch that forms along the walls of a hollow structure in the body, kind of like a cave. Usually we talk about these caves or pouches in the context of the large intestine, so it’d be a colonic diverticula, but it can also happen in the small ...
