Colonoscopy Procedure

A colonoscopy is a procedure used to examine the inner lining of the large intestine (colon) and rectum. It plays a crucial role in detecting and preventing colorectal cancer, as well as diagnosing various gastrointestinal conditions. Here’s what you need to know about the colonoscopy procedure:

Before the Procedure

Preparing for a colonoscopy is essential for accurate results and patient safety:

  • Preparation Instructions: You will receive detailed instructions on how to cleanse your colon before the procedure. This typically involves a liquid diet the day before and taking laxatives or other bowel-cleansing preparations to empty the colon completely.
  • Medications and Allergies: Provide a comprehensive list of all medications, including over-the-counter drugs and supplements, as well as any allergies to medications or substances.
  • Medical Conditions: Inform your healthcare team about any existing medical conditions, especially heart, lung, or bleeding disorders, and if you are taking diabetic medications or anticoagulants.

During the Procedure

The colonoscopy procedure is performed with the patient lying on their side:

  • Sedation: You will receive a sedative to help you relax and minimize discomfort. While sedated, you remain conscious and able to follow instructions.
  • Insertion of Colonoscope: A thin, flexible tube (colonoscope) with a camera and light at its tip is gently inserted through the rectum and guided through the colon. This allows the gastroenterologist to visually examine the lining of the colon on a monitor.
  • Air Insufflation: Air may be introduced through the colonoscope to expand the colon for better visualization. This may cause a sensation of fullness or cramping but should not interfere with breathing.
  • Biopsy or Treatment: If abnormalities are found, small instruments passed through the colonoscope can take tissue samples (biopsies) for further analysis or treat conditions such as polyps by removing them.

After the Procedure

After the colonoscopy, you will be monitored in a recovery area until most effects of the sedative wear off:

  • Post-Procedure Care: You will receive instructions on when you can resume eating and drinking, as well as any limitations on activities.
  • Results: Your gastroenterologist will discuss the findings with you after the procedure and any necessary follow-up care.
  • Minor Side Effects: Mild side effects like bloating or cramping may occur but typically resolve soon after the procedure.
  • Recovery: Plan to rest for the remainder of the day. Due to the sedative effects, avoid driving or operating machinery. Arrange for a friend or family member to accompany you home.

Possible Complications

Colonoscopy is generally safe, but complications are rare. Potential risks include:

  • Perforation: Rarely, the colonoscope may puncture the intestinal wall, which may require surgical repair.
  • Bleeding: In some cases, bleeding may occur at the biopsy site but can usually be managed during the procedure.

Your gastroenterologist will discuss any specific concerns and provide personalized guidance based on your individual health status and procedure findings.
