Emergency Medical Minute

Release Date: 06/12/2019

Author:  Nick Hatch, MD

Educational Pearls:

  • Postpolypectomy electrocoagulation syndrome (PES) is a rare complication of polypectomy and electrocautery during colonoscopy
  • Occurs when cautery causes transmural thickening from a contact burn
  • Patients can present as if they have peritonitis, with guarding, leukocytosis, fever, etc.
  • CT is the imaging of choice mainly to evaluate for bowel perforation as PES may not be seen on imaging
  • Treatment is often with antibiotics and supportive care - in severe cases, hospitalization may be required.
