[Colonic diverticulosis: which patients need surgery?]

Area of Science:

• Gastroenterology and Surgical Oncology
• Colorectal Surgery

Context:

• Diverticular disease is a common and increasing condition, affecting both older and younger populations.
• The epidemic rise necessitates updated therapeutic guidelines, particularly for elective surgical interventions.
• Previous indications for colectomy were less stringent, often based on suspicion rather than definitive diagnosis.

Purpose:

• To redefine and update the current surgical indications for elective colectomy in patients with diverticular disease.
• To emphasize the necessity of computed tomography (CT) scan confirmation for diverticulitis diagnosis.
• To establish criteria for colectomy, including specific comorbidities and disease severity.

Summary:

• Elective colectomy is now indicated for specific conditions: endocarditis, diabetes, collagen disorders, immune deficiency, recurrent diverticulitis requiring hospitalization, or single complicated diverticulitis (abscess, fistula, stricture).
• A two-month delay post-symptoms is recommended for safe preoperative colonoscopy to exclude malignancy.
• Laparoscopic colectomy may require increased surgical skill due to more severe resected lesions and potentially higher conversion rates; open surgery may be preferred in select cases.

Impact:

• This updated approach aims to optimize surgical decision-making, ensuring colectomy is reserved for appropriate cases.
• The emphasis on colonoscopy pre-surgery enhances patient safety by ruling out concurrent colorectal cancer.
• The guidelines reflect the increasing severity of disease in patients undergoing surgery due to restricted indications.
