Inflammatory polyps (pseudopolyposis) Pseudopolyposis is a term hallowed by usage. Milk consumption may exacerbate the disease.Įndoscopic Image of Ulcerative Colitis with Pseudopolyps This relationship is reversed in Crohn disease. Smoking is negatively associated with ulcerative colitis. Psychological and psychosocial stress factors can play a role in the presentation of ulcerative colitis and can precipitate exacerbations. These when contiguous may fuse causing irregular masses. Show polyps made up primarily of granulation tissue. However, the outcome in patients with pseudopolyps is better than in those with similar disease extent and severity who do not have pseudopolyps.Īn important role for colonoscopy is in the surveillance of longstanding extensive ulcerative colitis where there is an increased risk of developing carcinoma. Pseudopolyps are associated with increased severity and more extensive involvement in UC. They tend to be taller than they are wide and can mimic neoplasms biopsy confirms that they are not neoplastic. They can range from a few millimeters in diameter to a centimeter or more. Long segment of the transverse colon with Pseudopolyps In contrast to Crohn's disease, lower endoscopy in ulcerative colitis shows continuous and circumferential involvement, with no normal areas of mucosa.Įndoscopic View of Ulcerative Colitis with Pseudopolyps Instead of reflecting light in large patches, the granular mucosa reflects a multitude of small points of light, giving the appearance of "wet sandpaper" The granular appearance is manifested by changes in light reflection during colonoscopy.

We recommend seeing the video clips in full screen mode.Įndoscopic findings in ulcerative colitis. Endoscopy in UC typically reveals the following findings: Erythema Loss of the usual fine vascular pattern Granularity of the mucosa Friability Edema. All endoscopic images shown in this Atlas contain video clips.

In these cases, about 30 cm of the terminal ileum is usually affected.ĭownload the video clips by clicking on the endoscopic images, if you wish to observe in full screen, wait to be downloaded complete then press Alt and Enter for Windows media, Real Player Ctrl and 3. Chronic and severe cases can be associated with areas of precancerous changes, such as carcinoma in situ or dysplasia.Īnatomically, the large majority of cases involve the rectum some patients develop terminal ileitis caused by an incompetent ileocecal valve. Chronic disease is associated with pseudopolyp formation in about 15-20% of cases. In severe cases, the submucosa may be involved in some cases, the deeper muscular layers of the colonic wall is also affected.Īcute severe colitis may result in a fulminant colitis or toxic megacolon, which is characterized by a thin-walled, large, dilated colon that may eventually become perforated. Ulcerative colitis involves only the mucosa it is characterized by the formation of crypt abscesses and a coexisting depletion of goblet cell mucin. This 53 year-old female suffering of longstanding ulcerative colitis.
