A proctoscopy or rigid sigmoidoscopy is a procedure to examine the insides of the rectum and the anus. A proctoscope is a hollow tube, usually with a tiny light at the end, that can also be used to take tissue samples for biopsies as a cancer screening tool.

What is a Proctoscopy?

  • A proctoscopy (also called rigid sigmoidoscopy) is a procedure to examine the inside of the rectum and the anus.

  • It is usually done to look for tumors, polyps, inflammation, bleeding, or hemorrhoids.

  • A proctoscope is a straight, hollow metal or plastic tube, sometimes with a tiny light at the end, that allows the gastroenterologist to make a detailed examination of the rectum.

  • An instrument that can take tissue samples for biopsy may be inserted through the hollow tube.

Why is a Proctoscopy done?

A proctoscopy is done to:

  • Detect disease in the rectum or anus.

  • Find the source of anal bleeding.

  • Find the cause of diarrhea or constipation.

  • Remove or monitor the development of existing polyps or growths.

  • Screen for colon cancer or monitor rectal cancer that has already been treated.

How to prepare for a Proctoscopy?

  • The most important preparation for proctoscopy is to thoroughly clean out the rectum.

  • It is important that this is done.

  • The more completely the rectum is emptied, the easier it is for the doctor to examine it.

  • Various methods can be used to clean the rectum, your doctor will recommend the best way for your case.

  • Many doctors will recommend using an enema to clear waste. Be sure to follow instructions as directed.

Procedure of Proctoscopy

  • Proctoscopy can be performed in either a hospital or outpatient office.

  • Most proctoscopy examinations do not require anesthesia.

  • The doctor will first do a preliminary rectal exam with a gloved lubricated finger, then gently insert the proctoscope.

  • As the scope is slowly and carefully passed through, you may feel as if you need to move your bowels.

  • Because air is introduced into your bowel to help the doctor see better with the proctoscope, you may feel some cramping or fullness.

  • Generally, there is little discomfort during the procedure.

Risks of a Proctoscopy

  • There is little risk associated with proctoscopy.

  • It is possible that a patient may experience rectal bleeding as a result of the insertion of the proctoscope or if the lining of the rectum is irritated.

  • A patient may also develop an infection after the procedure.
