A 77-year-old man who was positive for occult blood, underwent lower gastrointestinal tract endoscopy, which showed a 6-mm type Ⅰs adenomatous polyp in the ascending colon. Cold polypectomy was performed and he was discharged from our hospital after the procedure. Six hours later, he suddenly experienced right-sided abdominal pain and was transported by ambulance to our hospital. The physical findings included muscular guarding and rebound tenderness in the same area. Peritonitis caused by intestinal perforation was suspected. However, CT images showed only inflammatory findings localized to the site of polypectomy, and no obvious perforation was detected. Post-polypectomy syndrome was therefore suspected. He improved with conservative therapy and was discharged from our hospital on the eighth disease day.
