Diverticular Disease.

Our approach to the diagnosis and treatment of diverticulitis has evolved over the past 20 y. Routine use of antibiotics has decreased with recent studies suggesting simple cases of diverticulitis can be selectively managed without antibiotics. The criteria necessitating surgical intervention have also been amended as our understanding of the natural history of diverticulitis has grown. We favor selective use of antibiotics, percutaneous drainage, and surgery depending on the severity of the disease, patient factors, and clinical context.
