Colonoscopy is commonly used as a screening tool for colorectal polyps and cancer. It also offers a chance to remove polyps via the polypectomy technique. Colonoscopic polypectomy is a relatively safe procedure, yet there is the possibility of serious complications such as perforation and bleeding. Postpolypectomy coagulation syndrome presents with pain, fever, an elevated white blood cell count and signs of peritoneal irritation, and usually within 12 hours of the procedure. No free air is seen on plain films or a CT scan, which is different from frank bowel perforation. The management of postpolypectomy coagulation syndrome includes fasting, antibiotics and intravenous hydration. We report here on a case of a 53-year-old woman who underwent right hemicolectomy because she presented with fever, signs of peritoneal irritation and shock after colonoscopic polypectomy. The final diagnosis was postpolypectomy coagulation syndrome as there was no perforation in the resected specimen.
