| [ Summary ] |
Acute hemorrhagic rectal ulcers and stercoral ulcers are disorders that occur in elderly subjects with various underlying diseases. They are often accompanied by massive hematochezia. Acute hemorrhagic rectal ulcers are thought to develop due to a reduction in rectal blood flow, due to stress or supine position. This condition usually consists of circumferentially arranged ulcers, or ulcers in the lowermost portion of the rectum, near the dentate line. Stercoral ulcers are considered to be those caused by pressure on the colorectal mucosa from impacted fecal masses and the presence of antecedent episodes of severe constipation. This condition is most common in the rectum, but can develop in the colon. It rarely causes perforations or penetrations. Both of those conditions require immediate diagnostic and therapeutic attention. |
