Diverticular Disease, Colon
Outpouchings, herniations, or protrusions of the colon; Pseudodiverticulosis
Diverticulosis of the colon is characterized by diverticula in the colon. They represent herniations of the colonic mucosa and submucosa through thickened muscularis mucosae into the pericolic fatty tissue (Riddell et al. 2014). This happens in individuals who eat low-fiber diets when intraluminal pressure is increased and muscle layers of the colon wall are weak (West and Losada 2004). Uncomplicated diverticular disease (diverticulosis) may be asymptomatic or may present with left lower abdominal pain, fever, and diarrhea alternating with constipation. The symptoms are more prominent when inflammation of diverticula occurs (refer to as diverticulitis). This can lead to perforation with abscess or fistula formation. Gastrointestinal hemorrhage can also occur, usually arteriolar, causing bright red blood on the stool. Further complications are strictures of the colon and segmental colitis...
