Detailed Examination and Polyp Removal During Colonoscopy

Our high-definition endoscopy system allows the doctor to examine the lining of the colon in detail and identify subtle abnormalities.

When appropriate, tissue samples can be taken for pathological examination (biopsy) during the colonoscopy. Polyps identified during the examination may also be removed endoscopically, depending on their size, shape, location, and other clinical factors.

Removed polyps are sent for pathological examination to determine their characteristics and check for abnormal or cancerous cells.

If You Take Blood-Thinning Medications

If polyp removal (polypectomy) is planned and you take anticoagulant or antiplatelet medication (commonly referred to as “blood thinners”), please discuss this with the doctor in advance.

The doctor will advise you whether your medication needs to be temporarily stopped and, if so, when to stop and restart it.

Do not stop or change your medication on your own. Follow the instructions provided by your doctor.

Key Features of Endoscopic Polypectomy

Minimally Invasive

Endoscopic polypectomy does not require an abdominal incision. The procedure is performed through the body's natural opening using a colonoscope, minimizing the physical burden associated with surgical incisions.

Preserves the Colon

The procedure is designed to remove the polyp while preserving the surrounding colon and its function.

No Pain from Cutting the Polyp Itself

The lining of the colon does not have pain receptors that sense cutting in the same way as the skin. As a result, removing the polyp itself does not typically cause pain.

How Endoscopic Polypectomy Is Performed

Depending on the size, shape, and characteristics of the polyp, the doctor may use the following technique:

1. Lifting the Polyp

For certain flat or small polyps, a solution such as saline is injected into the layer beneath the polyp. This lifts the polyp away from the deeper layers of the colon, creating a protective cushion and helping reduce the risk of injury to the deeper bowel wall.

2. Placing the Snare

A specialized wire loop called a snare is positioned around the polyp and carefully tightened around its base.

3. Removing the Polyp

High-frequency electrical current is applied through the snare to cut and remove the polyp. At the same time, the current coagulates blood vessels at the removal site to help control bleeding.

Pathological Examination

The removed polyp is retrieved and sent for pathological examination to determine its characteristics and check for abnormal or cancerous cells.

After Your Examination or Polyp Removal

Going Home

After the doctor has explained your results and provided your examination report, you can go home the same day.

Eating After the Procedure

If your colonoscopy was for observation only and no biopsy or polyp removal was performed, you may eat normally after the examination.

If a polyp was removed, the doctor will provide specific dietary instructions for the first few days after the procedure to help reduce the risk of bleeding. Please follow these instructions carefully.

What You May Experience After the Procedure

For the first one or two days after the examination, you may experience mild abdominal bloating from gas remaining in the colon.

A very small amount of bleeding, such as a light trace of blood on toilet paper, may also occur after polyp removal.

When to Contact the Clinic

Please contact the clinic immediately if:
• Your abdominal pain becomes more severe
• The amount of bleeding clearly increases, such as enough blood to turn the toilet bowl red
