Abstract
Abstract: Diverticulitis is a symptomatic diverticular disease characterized by inflammation of the diverticulum. Until now, the pathophysiology of diverticulitis is not known with certainty. Interactions between factors such as genetic factors, colonic structure and motility, colonic microbiota, age, and diet are thought to play a role in the occurrence of the disease. Diverticulitis should be considered as a differential diagnosis of acute abdominal pain specifically in the lower left part of the abdomen. Diagnostic criteria in cases of diverticulitis are the presence of inflamed diverticula, intestinal wall thickening exceeding 3 or 5 mm, and increased contrast absorbing medium on CT Scan and MRI examinations. Any perforation, obstruction, fistulization, and abscess detected on any imaging examination can be a sign of complicating diverticulitis. The prognosis in patients with diverticulitis depends on age, the presence of comorbidities, and the severity of the disease.
