[Update: Management of colonic diverticulitis]

Area of Science:

• Gastroenterology
• Colorectal Surgery
• Medical Imaging

Background:

• Diverticulosis and diverticulitis management guidelines are evolving.
• Accurate disease classification is crucial for effective treatment planning.

Purpose of the Study:

• To provide an updated overview of colonic diverticulitis management strategies.
• To emphasize the utility of the Classification of Diverticular Disease (CDD) system.

Main Methods:

• Review of current literature and clinical practices for diverticulitis management.
• Application of the CDD system for disease grading based on CT scan or ultrasound imaging.

Main Results:

• Acute uncomplicated diverticulitis may be managed with antibiotics or solely symptomatic therapy.
• Complicated diverticulitis (abscess, perforation) requires interventional drainage or surgery.
• Resection with primary anastomosis is increasingly favored over Hartmann's procedure.
• Damage control surgery is indicated for patients with sepsis.

Conclusions:

• Treatment decisions for diverticulitis should be guided by disease severity and patient symptoms.
• Elective surgery indications are based on persistent complications like fistulas or stenosis, not solely on the number of episodes.
