Endorectal Ultrasound Scan (ERUS)
Understanding Endorectal Ultrasound Scans
An Endorectal Ultrasound Scan (ERUS) is a diagnostic procedure that uses ultrasound technology to create detailed images of the rectum and surrounding tissues. The scan involves the insertion of a small ultrasound probe into the rectum, which emits sound waves to produce images of the internal structures.
Purpose and Benefits of an Endorectal Ultrasound Scan
The primary purpose of an ERUS is to detect and evaluate abnormalities in the rectum and nearby structures. It is particularly beneficial in the early detection of rectal cancer, as it can accurately determine the depth of tumour invasion and the involvement of adjacent lymph nodes. This information is crucial in planning appropriate treatment strategies.
Conditions Detected by an Endorectal Ultrasound Scan
ERUS is primarily used for the detection and staging of rectal cancer. It can also detect other rectal pathologies such as polyps, inflammatory bowel disease, and anal fistulas.

Further Information on the Service
Scan Procedure
During an ERUS, a small ultrasound probe is inserted into the rectum. The probe emits sound waves that bounce off the tissues and create echoes, which are then converted into images on a monitor.
Preparation for the Scan
Before the scan, you may be asked to follow a special diet and use an enema to clean out your rectum. You should also inform your doctor of any medications you are taking.
What to Expect on the Day
The procedure is usually quick, often taking less than 30 minutes. You may experience some discomfort during the insertion of the probe, but the procedure is generally well-tolerated.
After the Scan
After the scan, you can usually resume your normal activities. The results will be analyzed by a radiologist and communicated to you by your doctor.
Alternative Imaging Options
Other imaging options include CT scan, MRI, and PET scan. The choice of imaging depends on the symptoms and the consultant's decision.
