BOOK YOUR ENDOSCOPY

Full Thickness Resection Device (FTRD)

FTRD is a specialised endoscopic tool used to remove abnormal tissue or early cancers from the digestive tract (usually the colon, rectum, or occasionally the stomach or small bowel) in one piece and through all layers of the bowel wall — a process called full-thickness resection.

FTRD is performed during a colonoscopy or gastroscopy using a flexible tube passed through the mouth or bottom.

Why might I need an FTRD procedure?

Your doctor may recommend FTRD if you have:

  •      A suspicious polyp that could not be safely removed by standard methods
  •      Scarred or previously attempted lesions
  •      Early cancers or high-risk polyps (precancerous)
  •      Subepithelial (beneath the surface) lesions
  •      Small growths in difficult locations (e.g., near folds or scars)

FTRD allows for complete removal without major surgery.

How is the procedure done?

  •      You will receive sedation or general anaesthetic.
  •      A specially modified endoscope is used with the FTRD system attached.
  •      The abnormal tissue is grasped and pulled into a cap, and a clip is deployed to close the bowel wall.
  •      The tissue is then cut out above the clip, removing all layers of the bowel wall at once.
  •      The clip remains in place to seal the area and prevent leakage.

What are the benefits?

  •       Minimally invasive – no cuts or external incisions
  •       Can remove difficult or previously untreatable lesions
  •       May avoid the need for bowel surgery
  •       Usually done as a day case or overnight stay
  •       Provides a full tissue sample for accurate diagnosis

What are the risks?

FTRD is generally safe, but possible risks include:

Risk

Details

Bleeding

   Usually mild and managed during the procedure

Perforation (hole in bowel)

   Rare due to the clip, but possible

Pain or cramping

   Temporary, may need mild pain relief

Clip-related symptoms

   Mild discomfort or temporary bowel habit changes

Incomplete removal

   Rare, but further treatment may be needed

What happens after the procedure?

  •      You will be monitored in recovery.
  •      Most people go home the same day or after an overnight stay.
  •      Diet: You may be asked to follow a soft or low-residue diet for a few days.
  •      The clip usually falls off on its own after a few weeks and passes naturally.
  •      You’ll have a follow-up appointment to discuss the results and next steps.

Frequently Asked Questions

Q: Will I need surgery afterward?
A: In most cases, no. If the entire lesion is removed and no cancer is found, surgery can often be avoided.

Q: Does it hurt?
A: You shouldn’t feel anything during the procedure. Mild cramping or discomfort is possible afterward.

Q: Is the clip permanent?
A: No. The clip usually falls off by itself within weeks and passes naturally.

Q: Can I return to normal activities?
A: Most people resume normal activities within 1–2 days.
