Aim:
This paper addresses the current status of the treatment of acute colonic diverticulitis by an evidence-based review.
Method:
A systematic search in PUBMED, MEDLINE, EMBASE and Google scholar on colonic diverticulitis was performed. Diagnostic tools, randomized controlled trials, non-randomized comparative studies, observational epidemiological studies, national and international guidelines, reviews of observational studies on elective and emergency surgical treatment of diverticulitis, and studies of prognostic significance were reviewed. Criteria for eligibility of the studies were diagnosis and classification, medical treatment, inpatients and outpatients, diverticulitis in young patients, immunosuppression, recurrence, elective resection, emergency surgery, and predictive factors.
Results:
Some 92 publications were selected for comprehensive review. The review highlighted that computed tomography is the most effective test in the diagnosis and staging of acute diverticulitis; outpatient treatment can be performed for uncomplicated diverticulitis in patients without associated comorbidities; conservative treatment is aimed at those patients with uncomplicated acute diverticulitis; elective surgery must be done on an individual basis; laparoscopic approach for elective treatment of diverticulitis is appropriate but may be technically complex; in perforated diverticulitis, resection with primary anastomosis is a safe procedure that requires experience and should take into account strict exclusion criteria.
Conclusion:
The heterogeneity of patients with colonic diverticular disease means that both elective and urgent treatment should be tailored on an individual basis.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...
