From the Guidelines
For a patient with persistent fecal loading after multiple 2-4L PegLyte washouts, the next step should be to consider a combination of stimulant laxatives and enemas, as recommended by the American Gastroenterological Association and American College of Gastroenterology clinical practice guideline 1.
Current Situation
The patient has already undergone multiple 2-4L PegLyte washouts without resolving the fecal loading, indicating a need for a more aggressive approach.
Recommended Approach
- Administer a stimulant laxative, such as bisacodyl or sodium picosulphate, as recommended by the guideline 1, to enhance bowel motility and facilitate the passage of stool.
- Use enemas, specifically oil retention enemas followed by phosphate enemas, to help soften and break up the impacted stool, as suggested in the management of adult patients with severe chronic small intestinal dysmotility 1.
- Consider manual disimpaction under sedation if the above measures fail to resolve the impaction.
- Maintain the patient's hydration status with IV fluids if needed, and implement a maintenance regimen including daily osmotic laxatives, adequate fluid intake, and dietary modifications with increased fiber once the impaction is resolved.
Rationale
The guideline recommends the use of stimulant laxatives, such as bisacodyl or sodium picosulphate, for the treatment of chronic idiopathic constipation 1, and the use of enemas and manual disimpaction for the treatment of fecal impaction 1. This approach is necessary to prevent serious complications, such as bowel perforation, megacolon, or volvulus, and to improve the patient's quality of life.
Key Considerations
- Investigate the underlying cause of the severe constipation, which may be due to medication side effects, neurological disorders, metabolic abnormalities, or structural issues requiring specific treatment.
- Monitor the patient's response to treatment and adjust the approach as needed to ensure the best possible outcome.

Next Steps for Patient with Fecal Loading
If a patient still has fecal loading after multiple 2-4L PegLyte washouts, the next steps may include:
- Considering alternative bowel preparation methods, such as sodium picosulfate/magnesium citrate 2, 3
- Adding adjunct therapies, such as bisacodyl, to enhance bowel cleansing 2, 3
- Using a split-dose regimen to improve bowel preparation quality 4, 5
- Evaluating the patient's overall health and medical history to determine the best course of treatment 6
Alternative Bowel Preparation Methods
Alternative bowel preparation methods, such as sodium picosulfate/magnesium citrate, have been shown to be effective and safe for bowel preparation 2, 3. These methods may be considered for patients who have not responded to PegLyte washouts.
Adjunct Therapies
Adjunct therapies, such as bisacodyl, may be added to enhance bowel cleansing 2, 3. These therapies can help improve bowel preparation quality and reduce the risk of fecal loading.
Split-Dose Regimens
Split-dose regimens, where the bowel preparation is administered in two or more doses, have been shown to improve bowel preparation quality 4, 5. This approach may be considered for patients who have not responded to single-dose regimens.
Patient Evaluation
It is essential to evaluate the patient's overall health and medical history to determine the best course of treatment 6. This includes considering any underlying medical conditions, medications, and other factors that may impact bowel preparation.
