Should a patient with diverticulitis and micro perforation be accepted for treatment at a facility without gastroenterology services?

Management of Diverticulitis with Microperforation at a Facility Without Gastroenterology Services

A patient with diverticulitis and microperforation should not be accepted for treatment at a facility without gastroenterology services, as these patients require specialized care and potential surgical intervention that may not be available at your facility. 1

Risk Assessment for Complicated Diverticulitis

Diverticulitis with microperforation represents a form of complicated diverticulitis that carries significant risk for progression to more severe disease. Several key factors indicate the need for specialized care:

• Microperforation on CT indicates a high risk of progression to more severe disease and potential treatment failure 1
• Patients with evidence of perforation require close monitoring and may need surgical consultation 2
• Extraluminal air on CT is a predictor of failure of non-operative management 2

Required Resources for Management

Management of diverticulitis with microperforation requires:

1. Surgical expertise: Immediate access to colorectal or general surgeons experienced in managing complicated diverticulitis
2. Interventional radiology: Capability for percutaneous drainage if abscesses develop
3. Intensive care support: For monitoring and managing potential sepsis
4. Gastroenterology consultation: For follow-up management and colonoscopy after resolution

Treatment Considerations

The 2020 World Society of Emergency Surgery guidelines emphasize that:

• Patients with diffuse peritonitis due to diverticular perforation require prompt emergency operation 2
• Generalized diverticular peritonitis is a life-threatening condition requiring immediate intervention 2
• Even small amounts of distant intraperitoneal gas are associated with high failure rates (57-60%) of non-operative management 2

Special Considerations

Immunocompromised Patients

Immunocompromised patients with diverticulitis are at particularly high risk:

• They are more likely to present with severe or complicated disease 2
• There should be a low threshold for cross-sectional imaging, antibiotic treatment, and consultation with a colorectal surgeon 2
• These patients are at high risk for progression to complicated diverticulitis and/or sepsis 2

Surgical Options

If the patient's condition deteriorates, surgical options include:

• Damage control surgery with staged laparotomies for unstable patients 2
• Hartmann's procedure for unstable patients or those with multiple comorbidities 2
• Surgical resection and anastomosis for stable patients 2

Recommended Course of Action

Given these considerations:

1. Transfer the patient to a facility with gastroenterology and surgical services
2. Stabilize before transfer with:
   • Broad-spectrum antibiotics covering gram-negative and anaerobic bacteria
   • Fluid resuscitation
   • NPO status
   • Pain management
3. Monitor closely for signs of clinical deterioration during transfer arrangements

Pitfalls to Avoid

• Delaying transfer of patients with microperforation increases mortality risk 1
• Underestimating the severity of diverticulitis with microperforation can lead to treatment failure
• Attempting to manage these patients without surgical backup could result in emergency situations without appropriate resources

In conclusion, while your facility may be able to manage uncomplicated diverticulitis, the presence of microperforation significantly increases the risk profile and necessitates care at a facility with gastroenterology services and surgical expertise.
