Other Diagnostic Studies
- Internal hemorrhoids can be viewed only using the anoscope or the flexible sigmoidoscope.
- Hemorrhoids appear as bulging bluish mass above the dentate line.
- If there is accompanying constitutional symptoms (e.g. weight loss) , colonoscopy should be done to exclude colon cancer.
