Procedure
- The physician can see the inside of the rectum, sigmoid colon, as well as most of the descending colon with the help of a microscopic recording device at the tube's tip.
- During a flexible sigmoidoscopy exam, tissue samples (biopsies) can be extracted via scope if required.
- The doctor cannot see the whole colon with flexible sigmoidoscopy.
- As a result, flexible sigmoidoscopy alone is unable to detect cancer or small aggregates of cells that may grow into cancer (polyps) in the colon.
What to expect before the surgery?
- You must inform your doctor about the following:
- If you're expecting
- If you have any other disease- diabetes mellitus, lung disease, heart disease
- If you're allergic to any medication
- If you are on any regular medications, your doctor might adjust them accordingly.
- Your doctor will suggest you a clear liquid diet or overnight fasting.
- Your doctor might ask you to have a laxative either in a pill or liquid form.
What to expect on the day of surgery?
- To ensure a safe and successful procedure:
- The healthcare team will ensure that your colon is entirely empty, or else it might create an obstruction.
- An enema kit that aids in the emptying of the colon will be provided to you approximately two hours before the procedure.
What to expect during the surgery?
- The doctor will ask you to lie down on your left side and will perform the following steps:
- A narrow, lubricated sigmoidoscope is inserted inside the lower intestine via the rectum.
- Pumps air into the large intestine through the scope for a clearer look.
- The doctor analysis the visuals from inside the rectum
- If required, your doctor might insert small devices to eliminate tissue samples or polyps to biopsy.
- The scope is then taken out.
