Endoscopy

A colonoscopy is a procedure used to perform both diagnostic and therapeutic interventions via a camera that visualizes your colon and the last segment of your small bowel (terminalileum). The procedure typically takes 10 to 30 minutes. You will generally be under light sedation, ensuring that you do not feel or remember the procedure.

Preparation:
A colonoscopy requires bowel preparation before the procedure, which involves cleansing your gastrointestinal tract to ensure adequate visualization of the colonic mucosa.

During the Procedure:

• CO₂ is used to distend the colon, aiding visualization.
• If a polyp is detected, Dr. Petrushnko will remove it during the procedure unless it is too large or located in an unfavorable position.
• If abnormalities are identified, biopsies will be taken, and a tattoo may be placed near the site to mark its location for future reference.

Safety:
Colonoscopy is a very safe and commonly performed procedure. However, there are some risks, including:

• Bowel perforation – rare
• Bleeding
• Injury to surrounding organs; liver, spleen – rare
• Infection

If you are taking blood-thinning medications or certain diabetes medications, please inform Dr. Petrushnko, as specific instructions on when to stop these medications will be provided.

Gastroscopy

A gastroscopy is a procedure used to visualize the upper gastrointestinal tract, including the oesophagus, stomach, and the upper half of the duodenum. It typically takes 5 to 10 minutes and is performed under light sedation.

Purpose:
This procedure is essential for diagnosing conditions such as:

• Hiatal hernias.
• Gastroesophageal reflux disease (GERD).
• Barrett’s oesophagus (a precancerous condition).
• Gastritis.
• Peptic ulcers.

Biopsies can also be performed during the procedure to test for:

• Bacterial infections, such as Helicobacter pylori, which may cause ulcers.
• Enzymatic deficiencies in the small bowel.

Experience:
You will have no recollection of the procedure. A small percentage of patients may experience temporary throat discomfort afterward.
