What is the initial management for stercoral proctitis?

Initial Management of Stercoral Proctitis

The initial management for stercoral proctitis should focus on urgent fecal disimpaction, administration of enemas, and laxatives to relieve the fecal impaction causing inflammation of the rectal wall. 1, 2

Diagnostic Considerations

• Stercoral proctitis is inflammation of the rectal wall caused by pressure from hardened fecal matter (fecaloma) 1
• Clinical presentation often includes:
  • Abdominal pain and distension (though pain may be absent in up to 62% of cases) 2
  • History of chronic constipation 1, 3
  • Elderly patients are most commonly affected (median age 76 years) 2
• Diagnostic imaging (CT scan) typically reveals:
  • Fecal impaction (96.7% of cases) 2
  • Bowel wall inflammation (72.9% of cases) 2
  • Pericolonic fat stranding (48.3% of cases) 2
  • Possible bowel wall thickening 1

Treatment Algorithm

First-line Management

1. Immediate fecal disimpaction

   • Manual disimpaction of stool to relieve pressure on the rectal wall 1
   • This is critical to prevent progression to perforation 1, 4

2. Administration of enemas

   • Should be given promptly after diagnosis 1, 2
   • Helps soften and evacuate impacted stool 1

3. Oral or rectal laxatives

   • Essential component of initial management 1
   • Facilitates complete evacuation of fecal material 2

4. Intravenous fluid resuscitation

   • Important to correct any fluid imbalances 1
   • Particularly critical in elderly patients 3

5. Antibiotic therapy

   • Consider broad-spectrum antibiotics if there are signs of infection or inflammation 1
   • Particularly important if there is evidence of ischemic changes or perforation 1

Monitoring and Follow-up

• Close monitoring for signs of perforation or peritonitis 4, 5
• Laboratory monitoring for elevated white blood cell count and lactic acid levels (may indicate ischemic changes) 1
• Serial abdominal examinations to assess for worsening tenderness or peritoneal signs 2, 3

Warning Signs Requiring Surgical Consultation

• Persistent or worsening abdominal pain despite disimpaction 4
• Signs of peritonitis (rigid abdomen, rebound tenderness) 4, 5
• Radiographic evidence of free air or perforation 4
• Elevated lactic acid levels suggesting ischemic changes 1
• Hemodynamic instability or sepsis 2, 5

Prevention of Recurrence

• Implement a bowel regimen to prevent recurrent constipation 2, 3
• Consider scheduled laxatives or stool softeners 2
• Increase dietary fiber and fluid intake 3
• Address underlying causes of constipation (medications, immobility) 3

Important Clinical Pitfalls

• Failure to recognize stercoral proctitis can lead to progression to stercoral ulceration and perforation, which carries mortality exceeding 50% 5
• Over 50% of patients discharged from emergency departments with stercoral colitis receive no enema, laxatives, or disimpaction, representing a significant gap in appropriate management 2
• Stercoral perforation accounts for 3.2% of all colon perforations and requires immediate surgical intervention 4
• Clinical presentation may be nonspecific, particularly in elderly patients, leading to delayed diagnosis 2, 3
