Management of colonic diverticulitis.

Area of Science:

• Gastroenterology
• Colorectal Surgery

Background:

• Left-sided colonic diverticulitis is a prevalent and expensive gastrointestinal condition in Western nations.
• It presents with acute, severe abdominal pain and necessitates imaging for diagnosis and staging.

Purpose of the Study:

• To outline diagnostic and management strategies for left-sided colonic diverticulitis.
• To discuss the evolving treatment paradigms, including non-operative management and surgical interventions.

Main Methods:

• Review of diagnostic imaging modalities for initial assessment.
• Guidelines for colonoscopy post-diagnosis to exclude malignancy.
• Selective antibiotic use in mild, uncomplicated cases.
• Considerations for prophylactic colon resection based on individual patient factors.

Main Results:

• Imaging is crucial for diagnosis and severity assessment.
• Colonoscopy is recommended weeks after diagnosis to rule out colon cancer.
• Antibiotics are selectively used for mild, uncomplicated diverticulitis.
• Non-operative management is increasingly favored, with surgery reserved for complicated cases like abscesses or peritonitis.

Conclusions:

• Management of left-sided colonic diverticulitis involves a stepwise approach, from diagnosis to treatment.
• Individualized decisions regarding surgery are essential, weighing risks and benefits.
• Recurrence remains a possibility even after surgical resection.
