Pathophysiology and When Antibiotics Help

Why are we still treating acute uncomplicated diverticulitis with antibiotics? There is plenty of evidence from several randomized controlled trials demonstrating that symptomatic management alone yields similar results. If we should continue prescribing antibiotics for acute uncomplicated diverticulitis, which patients should undergo treatment and when? Join Drs. Jared Hendren, Elissa Dabaghi, Joseph Trunzo, Ajaratu Keshinro, and David Rosen as they discuss the management of uncomplicated diverticulitis while reviewing groundbreaking literature.
