What it is

A colonoscopy is a procedure where a long, flexible tube with a camera attached (colonoscope) is inserted into the rectum and advanced through the entire colon. This allows the doctor to visualize the lining of the colon and identify any abnormalities, such as polyps, ulcers, inflammation, or tumors.

During a colonoscopy, if any suspicious areas are found, the doctor can take biopsies (tissue samples) for further examination under a microscope. Polyps, which are small growths that can potentially develop into cancer, can also be removed during the procedure (polypectomy). Colonoscopy is a valuable tool for both diagnosing and preventing colorectal cancer.

Colonoscopy can also be used therapeutically for dilation of colonic strictures, decompression of the colon, and to stop bleeding.

Am I a candidate?

Who is a Good Candidate for a Colonoscopy?

A colonoscopy is recommended for various individuals, including:

  • Screening: Asymptomatic individuals at average risk for colorectal cancer, typically starting at age 45.
  • Surveillance: Patients with a personal or family history of colorectal cancer or polyps, or a history of inflammatory bowel disease.
  • Diagnostic Evaluation: Patients with symptoms such as rectal bleeding, chronic diarrhea or constipation, abdominal pain, or other concerning signs.

Recovery

What is the Recovery Like?

Recovery after a colonoscopy is typically very quick. Patients may experience some mild cramping or bloating for a few hours due to the air insufflated during the procedure. Most patients can resume a normal diet and activities the following day. If sedation was used, patients will need someone to drive them home and should avoid making important decisions or operating machinery for the rest of the day. If a polyp was removed, there may be some dietary or activity restrictions for a short period.

Risks & considerations

What are the Risks?

While colonoscopy is a very safe procedure, potential risks and complications can occur, although they are uncommon. These include:

  • Bleeding: Minor bleeding can occur, particularly after a biopsy or polypectomy. Significant bleeding requiring intervention is rare.
  • Perforation: A tear in the colon wall is a rare but serious complication that may require surgical repair. The risk is higher with therapeutic procedures.
  • Sedation-Related Complications: Risks associated with sedation include adverse reactions to medication, breathing problems, or cardiovascular events.
  • Post-Polypectomy Syndrome: A rare complication involving abdominal pain, fever, and inflammation after polyp removal, which typically resolves with conservative management.
