Diverticulosis is the condition of having multiple pouches (diverticula) in the colon that are not inflamed. These are outpockets of the colonic mucosa and submucosa through weaknesses of muscle layers in the colon wall. [1] Diverticula do not cause symptoms in most people. [2]
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 ...
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.
Hinchey Classification is used to describe perforations of the colon due to diverticulitis. The classification was developed by Dr. E John Hinchey (1934–present), a general surgeon at the Montreal General Hospital and professor of surgery at McGill University. Diverticulosis (the presence of bowel diverticula) is an essentially ubiquitous ...
While a low-fiber diet is generally used for acute diverticulitis, the NIH guidelines recommend a high-fiber diet for patients with diverticulosis (a condition that may lead to diverticulitis). [17] A Mayo Clinic review from 2011 showed that a high-fiber diet can prevent diverticular disease.
A Meckel's diverticulum, a true congenital diverticulum, is a slight bulge in the small intestine present at birth and a vestigial remnant of the vitelline duct.It is the most common malformation of the gastrointestinal tract and is present in approximately 2% of the population, [1] with males more frequently experiencing symptoms.
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
