What is Rigid Sigmoidoscopy?

  1. Rigid sigmoidoscopy is a medical procedure to examine the inside of the rectum and the anus.
  2. It is also known as Proctoscopy commonly. The lower part of the colon near the anus is called the sigmoid colon.
  3. The rigid sigmoidoscopy can be used for both diagnostic and therapeutic purposes.
  4. It is performed using the rigid sigmoid scope inserted in the rectum.
  5. It is done to evaluate the health of the person's rectum and the lower part of the colon.
  6. In addition, it helps diagnose haemorrhoids, polyp tumours, and other abnormal growth in the rectum and colon.

What will happen if rigid sigmoidoscopy is delayed?

  1. The rigid sigmoidoscopy is used to examine the inside of the anus and the rectum so that causes of inflammation and abnormal discharge from the anus can be detected. It helps in the early detection of irritable bowel diseases so that early treatment can be started. 
  2. The tissue samples during the rigid sigmoidoscopy procedure are sent for the biopsy to help detect the cancerous polyps. If the rigid sigmoidoscopy is delayed, cancer may spread to other body parts. Once the cancer is spread and reaches the advanced stage, it becomes difficult to control it and eventually leads to the person's death.
  3. Apart from cancer diagnosis, the procedure also helps in diagnosing several diseases, such as strictures, diverticulitis and haemorrhoids. Delaying rigid sigmoidoscopy to diagnose these conditions may lead to disease progression and complications, such as peritonitis, which is a complication of diverticulitis and requires immediate medical intervention.


Benefits of Rigid Sigmoidoscopy

  1. Rigid sigmoidoscopy may be useful in anorectal diseases such as bleeding per rectum or inflammatory rectal disease, particularly in the general practice and paediatrics.
  2. For performing the examination, the patient must lie on the left side, in the so-called Sims' position
