Acute colitis after flexible endoscopy is linked to glutaraldehyde exposure from instrument cleaning. Prompt recognition and proper disinfection can prevent this gastrointestinal complication.

Area of Science:

  • Gastroenterology
  • Endoscopy
  • Colitis Etiology

Background:

  • Flexible endoscopic procedures are common diagnostic tools.
  • Complications, though rare, require thorough investigation.
  • Instrument reprocessing is critical for patient safety.

Purpose of the Study:

  • To investigate the cause and clinical progression of acute colitis following flexible endoscopy.
  • To identify potential risk factors and patient outcomes.

Main Methods:

  • Retrospective chart review of eight patients presenting with post-endoscopy colonic symptoms.
  • Analysis of symptoms, timing, endoscopic findings, and treatment response.
  • Histopathological examination of biopsy specimens.

Main Results:

  • All patients developed abdominal pain, bloody diarrhea, and mucus within 48 hours post-procedure.
  • Colitis was confirmed endoscopically; one patient required hospitalization.
  • Biopsies showed ischemic-type injury; symptoms resolved with treatment.

Conclusions:

  • Glutaraldehyde exposure during instrument disinfection is a likely cause of acute colitis.
  • Proper instrument cleansing protocols are essential to mitigate this risk.
  • Early recognition and management lead to favorable outcomes.
