From the Guidelines
Colonoscopy is a highly effective tool for the early detection and prevention of colorectal cancer, with benefits including the removal of precancerous polyps, investigation of symptoms like rectal bleeding and abdominal pain, and a significant reduction in colorectal cancer mortality, as supported by a recent peer-reviewed study published in 2023 in Gastroenterology 1. The research highlights the importance of colonoscopy in preventing colorectal cancer, with the ability to remove polyps during the procedure being a significant advantage in cancer prevention.
- The study validates that colonoscopy serves as an important diagnostic tool for investigating symptoms like rectal bleeding and abdominal pain.
- Regarding risks, the research acknowledges the potential for complications including perforation, post-polypectomy bleeding, and adverse reactions to sedation.
- The study also confirms that patient discomfort remains a consideration, both from the bowel preparation process and post-procedure recovery.
- A recent study published in JAMA in 2021 also reports on the harms associated with screening colonoscopy, including serious bleeding events and perforations, with rates of 14.6 major bleeding events per 10,000 colonoscopies and 3.1 perforations per 10,000 colonoscopies 1.
- Another study published in Annals of Internal Medicine in 2019 provides guidance on screening for colorectal cancer in asymptomatic average-risk adults, including the benefits and harms of different screening tests, including colonoscopy 1.
- The 2023 study published in Gastroenterology provides the most recent and highest quality evidence, and its findings should be prioritized when making decisions about colonoscopy procedures 1.

From the Research
Risks and Benefits of Colonoscopy
The benefits of colonoscopy include:
- Early Detection: Colonoscopy allows for the detection of colorectal cancer at stages where treatment is more effective 2.
- Polyp Removal: The procedure enables medical professionals to remove polyps during the examination, preventing the development of colorectal cancer 2.
- Diagnostic Tool: Colonoscopy is used to investigate rectal bleeding and unexplained abdominal pain, as well as for early detection purposes 3, 4, 5.
The risks of colonoscopy include:
- Complications: Possible side effects include bowel perforation, bleeding, and adverse reactions to sedation medications 2, 6.
- Discomfort: The procedure can cause discomfort to patients, including post-procedure pain and side effects from bowel preparation 3, 4, 5.
Bowel Preparation for Colonoscopy
Bowel preparation is essential for a successful colonoscopy, with studies recommending the use of split-dose bowel preparation regimens 5 and oral sulfate solutions (OSS) as a bowel preparation regimen 4. The quality of bowel preparation is defined as adequate when standard screening or surveillance intervals can be assigned based on the findings of the colonoscopy 5.
Efficacy and Safety of Colonoscopy
The efficacy and safety of colonoscopy have been evaluated in several studies, with results showing that colonoscopy is an effective tool for the early detection and prevention of colorectal cancer 2. The procedure has also been shown to have a low risk of serious adverse events, such as perforations and major bleeding 2.
