Podcast # 477: Postpolypectomy Electrocoagulation Syndrome

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.
