However, CT scan is the mainstay of diagnosing diverticulitis and its complications. [12] The diagnosis of acute diverticulitis is made confidently when the involved segment contains diverticula. [42] CT images reveal localized colon wall thickening, with inflammation extending into the fat surrounding the colon. [43]
Bowel wall thickening [29] Intestinal mesenteric stranding [32] Evidence of adjacent solid organ infarctions to the kidney or spleen, consistent with a cardiac embolic shower phenomenon; In embolic acute intestinal ischemia, CT-Angiography can be of great value for diagnosis and treatment.
Invasion of tumours through the layers of the gastrointestinal wall is used in staging of tumour spread. This affects treatment and prognosis. The normal thickness of the small intestinal wall is 3–5 mm, [6] and 1–5 mm in the large intestine. [7] Focal, irregular and asymmetrical gastrointestinal wall thickening suggests a malignancy. [7]
Laboratory results are usually normal in SCAD, although the white blood cell count may be mildly elevated. 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.
The normal thickness of the small intestinal wall is 3–5 mm, [8] and 1–5 mm in the large intestine. [9] Focal, irregular and asymmetrical gastrointestinal wall thickening on CT scan suggests a malignancy. [9] Segmental or diffuse gastrointestinal wall thickening is most often due to ischemic, inflammatory or infectious disease. [9]
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.
Barium X-ray examinations are useful tools for the study of appearance and function of the parts of the gastrointestinal tract. They are used to diagnose and monitor esophageal reflux, dysphagia, hiatus hernia, strictures, diverticula, pyloric stenosis, gastritis, enteritis, volvulus, varices, ulcers, tumors, and gastrointestinal dysmotility, as well as to detect foreign bodies.
Unlike aminosalicylates, biologics can cause serious side effects such as an increased risk of developing extra-intestinal cancers, [115] heart failure; and weakening of the immune system, resulting in a decreased ability of the immune system to clear infections and reactivation of latent infections such as tuberculosis. For this reason, people ...
