“This publication summarizes the changing treatment paradigm for patients with left-sided diverticulitis. Although diverticular disease can affect any segment of the large intestine, we will focus on left-sided disease. Bowel preparation, enhanced recovery pathways, and prevention of thromboembolic disease, while relevant to the management of patients with diverticulitis, are beyond the scope of these guidelines and are addressed in other ASCRS clinical practice guidelines.”
