Abstract
Context
Postoperative, critically ill, and elderly patients often have fecal loading or impaction. In a few such patients, disimpaction of fecalomas and colon cleansing are difficult. Bowel obstruction, megacolon, lower gastrointestinal bleeding, and gut perforation are complications that may ensue. Oral laxatives or enemas may only be partially effective. Surgical intervention may be needed for salvage or to treat complications.
Series and Design
Fourteen hospitalized cases with defecation disorder due to fecal loading of the colon were enrolled for retrospective analysis. Colonoscopic instillation of mannitol and/or lactulose was undertaken as an intervention when the use of oral laxatives was either ineffective or unfeasible, and enema had yielded poor results.
Results
Ten patients had satisfactory outcomes for fecal clearance, whereas four patients with poor or incomplete responses underwent repeat interventions or surgery. No significant complications were encountered due to this therapy.
Conclusion
Colonoscopic instillation of mannitol or lactulose in fecal-loaded critically ill patients results in a safe and satisfactory fecal clearance.
