Diverticular Disease—An Updated Management Review

Diverticular disease is highly prevalent in the Western world, placing an increased burden on healthcare systems. This review clarifies the consensus in the literature on the disease’s classification, etiology, and management. Diverticular disease, caused by sac-like protrusions of colonic mucosa through the muscular colonic wall, has a varied disease course. Multiple theories contribute to our understanding of the etiology of the disease, with pathogenesis affected by age, diet, environmental conditions, lifestyle, the microbiome, genetics, and motility. The subtypes of diverticular disease in this review include symptomatic uncomplicated diverticular disease, segmental colitis associated with diverticulosis, and uncomplicated and complicated diverticulitis. We discuss emerging treatments and outline management options, such as supportive care, conservative management with or without antibiotics, and surgical intervention.
