Medical Society Guidelines

2015 American Gastroenterological Association (AGA) guidelines

The AGA recommendations on the treatment of diverticulitis include the following^[5]:

Antibiotics should be used selectively in uncomplicated diverticulitis.
Colonoscopy should be performed after resolution of acute diverticulitis if a high-quality examination has not been done recently.
Prophylactic colonic resection in uncomplicated diverticulitis should be done on a case-by-case basis.
A fiber-rich diet or fiber supplementation as well as physical activity (ideally, daily rigorous exercise) are recommended after resolution.
Aspirin use can be continued after resolution, particularly if it is being used for secondary prevention.
It is not necessary to avoid nuts and popcorn in patients with diverticulosis or diverticulitis.
Avoid nonaspirin, nonsteroidal anti-inflammatory drugs if possible.
Mesalamine, rifaximin, and probiotics are not recommended to prevent recurrence.

2006 American Society of Colon and Rectal Surgeons (ASCRS) practice parameters

The ASCRS recommendations on the management of diverticulitis include the following^[44]:

The initial evaluation should include a history and physical examination, complete blood cell count, urinalysis, and abdominal imaging in select cases.
Computed tomography (CT) scanning of the abdomen and pelvis is the most appropriate initial imaging method.
Ultrasonography and magnetic resonance imaging (MRI) can be useful imaging alternatives.
Nonsurgical treatment includes oral or intravenous antibiotics and diet modification.
Image-guided percutaneous drainage is usually the most appropriate treatment for stable patients with large diverticular abscesses.
After resolution of the incident diverticulitis, colonoscopy should be performed if it has not been done recently.
The decision regarding elective sigmoid colectomy should be individualized.
Elective colectomy should be considered after recovery from complicated diverticulitis.
Routine elective resection based on young age (< 50 years) is not recommended.
Urgent sigmoid colectomy is required for diffuse peritonitis or when nonsurgical management fails.
The decision to restore bowel continuity after resection must incorporate patient factors, intraoperative factors, and surgeon preference.
