Obstructive colitis (OC) is a nonspecific inflammatory condition that occurs at the proximal side of a completely or partially stenotic lesion typically caused by colorectal cancer. Impaired blood flow caused by these stenotic changes in the colon or rectum results in this condition. During surgery for sigmoid colon carcinoma with OC, complete surgical removal of the OC lesions is required. However, it is difficult to anticipate the range of OC before surgery. Diagnosing the potential ischemia during surgery would decrease the need for re-operation. This is the first report of HyperEye Medical System (HEMS) angiography for surgery of colon cancer with OC. We report a case of sigmoid colon carcinoma in which HEMS angiography was used and found to be useful for real-time detection of the OC lesion.
