Diverticular disease of colon

Last edited: 4/14/2026

Overview

Diverticular disease of the colon encompasses diverticulosis (presence of diverticula) and diverticulitis (inflammation of diverticula), often leading to complications such as abscess formation, fistula, bleeding, and toxic megacolon. 135

Diagnosis

  • Clinical Presentation: Abdominal pain, fever, changes in bowel habits.
  • Imaging: CT scans are crucial for diagnosing complications like abscesses, fistulas, and toxic megacolon 5.
  • Laboratory Tests: Elevated white blood cell count may indicate infection or inflammation 1.
  • Management

  • Surgical Intervention: Urgent or emergent colectomy may be required for complications like perforation, severe bleeding, or toxic megacolon 1.
  • Laparoscopic vs Open Surgery: Laparoscopic colectomy is associated with improved failure to rescue and reduced morbidity compared to open surgery 3.
  • Re-operation: Common indications include managing surgical complications; planned second look and supportive procedures are frequent 1.
  • Special Populations

  • Elderly: Higher risk of complications and may benefit from laparoscopic approaches to reduce morbidity 3.
  • Comorbidities: Patients with sepsis or requiring intraoperative vasopressors have increased morbidity and mortality, highlighting the need for careful perioperative management 1.
  • Key Recommendations

  • Consider Laparoscopic Approach for Emergent Colectomy to improve outcomes such as failure to rescue and reduce overall morbidity (Evidence: Moderate) 3.
  • Utilize CT Imaging for accurate diagnosis of complications like toxic megacolon and abscesses (Evidence: Expert opinion) 5.
  • Monitor for Re-operation Indications closely, recognizing that planned second look procedures are common and reflect necessary supportive care rather than solely negative outcomes (Evidence: Moderate) 1.
