Utility of multi-detector CT scans after colorectal endoscopic submucosal dissection: a prospective study

Several reports have described the major adverse events after endoscopic submucosal dissection (ESD), such as perforation or bleeding. However, few studies have discussed the occurrence of post-ESD electrocoagulation syndrome (PEECS) after colorectal ESD. Additionally, the occurrence of fever without abdominal pain in patients requires postoperative management similar to that required for PEECS. Therefore, we have defined post-ESD inflammatory syndrome (PEIS) as composed of both PEECS and fever without abdominal pain.
