An estimated 15%-25% of patients who present with a first episode of acute diverticulitis have complicated disease that requires surgery. According to the World Gastroenterology Organisation (WGO) 2007 guidelines, 15%-30% of patients admitted for the management of diverticulitis will need surgery during their admission, with a surgical mortality of 18%.
