Diverticular Disease Management
Diagnosis and Evaluation
- Early colonic evaluation is recommended after diagnosis to rule out malignancy or other pathologies, confirm extent of diverticular disease, and assess for complications like stenosis or fistulae in patients with diverticular disease 1, 2
Patient Monitoring
- Regular follow-up is necessary to monitor for development of symptoms, signs of progression to complicated disease, and response to conservative management in patients with diverticular disease 1, 2
- Higher risk population, such as immunocompromised patients, requires closer monitoring, and consideration of consultation with a colorectal surgeon for preventive elective sigmoid resection 2
Surgical Indications
- Surgery is generally not indicated for uncomplicated diverticular disease without symptoms, but may be considered in cases of complications such as stenosis, fistula formation, or recurrent diverticular bleeding, according to the World Society of Emergency Surgery 1
- Surgical consultation may also be considered for very symptomatic disease significantly compromising quality of life despite optimal medical management, and for immunocompromised patients at high risk for complications 1, 2
Treatment Approach
- Elective sigmoid resection should not be routinely recommended for asymptomatic diverticular disease, and it is essential to distinguish between diverticulosis and diverticulitis, as treatment approaches differ significantly between these conditions 1, 2
Diagnosis of diverticulitis should be confirmed with CT scan with IV contrast (or ultrasound/MRI if contrast is contraindicated) to guide appropriate treatment, according to the World Society of Emergency Surgery (WSES) staging, which includes:
Stage Description 0 Uncomplicated diverticulitis 1a-1b Complicated diverticulitis with pericolic air bubbles or small abscess 2a-2b Complicated diverticulitis with larger abscesses 3-4 Diffuse peritonitis [1] - Pain management strategy depends on the severity of diverticulitis, with acetaminophen as first-line therapy, and careful fluid management, according to the World Society of Emergency Surgery 1, 3
- Broad-spectrum antibiotic therapy is recommended for complicated diverticulitis, with options including oral or IV antibiotics, and a short course (3-5 days) is sufficient with adequate source control, while antibiotics should be avoided in immunocompetent elderly patients with uncomplicated diverticulitis 1
- Outpatient management is appropriate for patients with uncomplicated diverticulitis who can take fluids orally, can manage themselves at home, and have no significant comorbidities, while inpatient management with IV fluids and antibiotics is recommended for older adults with significant comorbidities, inability to take oral fluids, or signs of complicated diverticulitis 3
- Conservative management without antibiotics is recommended for uncomplicated diverticulitis, including bowel rest, hydration, and pain management, particularly for immunocompetent elderly patients, according to the World Society of Emergency Surgery 1
- Surgical management options include Hartmann operation, resection with primary anastomosis, and laparoscopic sigmoidectomy, with damage control surgery recommended for physiologically unstable patients 1
- Monitoring for treatment failure is warranted if signs of peritonitis or systemic illness persist beyond 5-7 days of treatment, with risk factors for treatment failure including Ambrosetti score of 4 and free air around the colon, and early colonic evaluation after resolution of acute episode is recommended 1
- Most recommendations for elderly patients are based on low or very low-quality evidence due to lack of high-quality studies specifically focusing on this population, and emergency surgery carries significantly higher mortality compared to elective procedures 1
