Diverticular Disease: Rapid Evidence Review

Area of Science:

• Gastroenterology
• Surgical Gastroenterology

Background:

• Diverticulitis presents with characteristic symptoms like left lower quadrant pain and leukocytosis.
• Accurate diagnosis and staging are crucial for effective management.

Purpose of the Study:

• To outline diagnostic criteria for diverticulitis.
• To detail treatment strategies for complicated and uncomplicated diverticulitis.
• To provide recommendations for diverticulitis prevention.

Main Methods:

• Clinical presentation analysis for diagnosis.
• Laboratory workup including complete blood count, basic metabolic panel, urinalysis, and C-reactive protein.
• Computed tomography with intravenous contrast for diagnosis confirmation and complication assessment.
• Treatment categorization based on disease complexity (complicated vs. uncomplicated).

Main Results:

• Uncomplicated diverticulitis may be managed without antibiotics.
• Complicated diverticulitis requires hospitalization with dietary modification, antibiotics, and pain management.
• Percutaneous drainage is indicated for abscesses ≥3 cm; surgery is reserved for refractory cases.
• Colonoscopy is recommended six weeks post-symptom resolution for complicated cases without recent high-quality examination.

Conclusions:

• Prompt diagnosis and appropriate management based on disease severity are key to successful diverticulitis treatment.
• Lifestyle modifications, including diet and exercise, are vital for diverticulitis prevention.
• Surgical intervention is typically reserved for severe or recurrent cases.
