Diverticulitis is defined as diverticular disease with signs and symptoms of diverticular inflammation. Clinical features of acute diverticulitis include constant abdominal pain, localized abdominal tenderness in the left lower quadrant of the abdomen, nausea, vomiting, constipation or diarrhea, fever and leukocytosis .
In Western countries, diverticular disease most commonly involves the sigmoid colon (95 percent of people with diverticulitis). [83] Diverticulosis affects 5–45% of individuals with the prevalence of diverticulosis increasing with age from under 20% of individuals affected at age 40 up to 60% of individuals affected by age 60. [83]
Unlike other diverticular diseases, SCAD symptoms spontaneously resolve on its own without or with very limited pharmaceutical intervention. Endoscopic evaluation and biopsy are needed for diagnosis. They should show evidence of inflammation in the mucosa in-between diverticula, with sparing of the rectum and proximal colon. [13]
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.
Segmental colitis associated with diverticulosis (SCAD) is a condition characterized by localized inflammation in the colon, which spares the rectum and is associated with multiple sac-like protrusions or pouches in the wall of the colon (diverticulosis). Unlike diverticulitis, SCAD involves inflammation of the colon between diverticula ...
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 ...
A Laimer diverticulum is an outpouching that occurs in the Laimer triangle between the cricopharyngeus and superior esophageal circular muscle. Colonic diverticula, although found incidentally during colonoscopy, may become infected (see diverticulitis) and can perforate, requiring surgery. [8] Gastric diverticula are very infrequent. [9]
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 ...
