Postpolypectomy coagulation syndrome - an uncommon complication of colonoscopy.

Colonoscopy is the most sensitive and specific test for detecting colon cancer and is a common procedure performed in over 19 million people annually in the United States as of 2017. Though the incidence of complications from colonoscopy is low, there are several important complications that may require surgical intervention including bowel perforation, bleeding, splenic injury, and diverticulitis. Post-polypectomy coagulation syndrome (PPCS) is an uncommon complication of colonoscopy however, clinical presentation mimics bowel perforation and the differentiation between the two is vital as the management differs. Herein we present a case of a 43-year-old female with abdominal pain after undergoing colonoscopy and developed PPCS. • Post-polypectomy coagulation syndrome is a rare complication following colon polypectomy using electrocauterization. • Patients with abdominal pain after colonoscopy should be evaluated with cross-sectional imaging to rule out perforation. • Focal mural wall thickening with surrounding fat infiltration and absence of extraluminal air are imaging hallmarks of PPCS.
