A 67-year-old man with diabetes mellitus was admitted to our hospital for endoscopic mucosal resection (EMR) of a polyp in the transverse colon. The EMR was done successfully without any obvious intraoperative procedural complications. The next day, he presented with a fever of 39.8 degrees Celsius. The complete blood cell count showed an elevated WBC count. Physical examination showed normal abdominal findings. CT showed a low-density tumor and a “target sign” at the transverse colon near the clips of EMR. Based on the CT findings, laboratory data and endoscopic findings, we made the diagnosis of colonic intussusception caused by a submucosal abscess. The intussusception was reduced by air insufflation under colonoscopy. Closing the ulcer under insufficient preparation and susceptibility to infection related to diabetes mellitus were suspected to have caused colonic abscess.
