AI-Powered Colonoscopy

Discover how artificial intelligence is supporting gastroenterologists in identifying colorectal polyps and improving colonoscopy detection.

Colorectal cancer is one of the most common cancers worldwide, but many cases develop from polyps that can be identified and removed before they become cancerous. Colonoscopy plays an important role in detecting these growths, and advances in artificial intelligence (AI) are helping gastroenterologists examine the colon more carefully.

AI-assisted colonoscopy is an emerging technology designed to support polyp detection during a procedure. By analyzing images from the colonoscope in real time, AI systems can alert the gastroenterologist to areas that may need a closer look.

At Abu Hammour Gastroenterology Center in Dubai Healthcare City, understanding advances in digestive health technology can help patients make informed decisions about colorectal cancer screening.

What are colorectal polyps?

Colorectal polyps are small growths that develop on the inner lining of the colon or rectum. Many are harmless, but some types particularly adenomas and certain serrated polyps—can develop into colorectal cancer over time.

Polyps may vary in size, shape, and appearance. Some are easy to see, while others are small, flat, or hidden behind folds in the colon.

Most polyps do not cause noticeable symptoms. This is why screening colonoscopy is important, even when a person feels healthy.

During a colonoscopy, a gastroenterologist examines the lining of the colon using a flexible instrument equipped with a camera. If a polyp is found, it can often be removed during the same procedure and sent for laboratory examination.

How does AI-powered colonoscopy work?

AI-assisted colonoscopy uses computer-aided detection (CADe) software to analyze the live video feed from the colonoscope. The system is trained to recognize visual patterns that may indicate a polyp.

During the examination, the technology works alongside the gastroenterologist in several ways:

1. Analyzes images in real time

AI software continuously examines the images captured by the colonoscope as it moves through the colon.

2. Highlights suspicious areas

When the system identifies a visual pattern that may be a polyp, it can place a marker or highlight on the screen to draw the gastroenterologist's attention to that area.

3. Supports the gastroenterologist

The doctor evaluates the highlighted area, determines whether it is a polyp, and decides whether it should be removed or further examined.

AI acts as an additional visual aid—not as a replacement for the gastroenterologist's expertise, judgment, or careful examination.

Can AI help detect polyps that might otherwise be missed?

One of the potential benefits of AI-assisted colonoscopy is its ability to draw attention to subtle lesions that may be difficult to notice.

Polyps can be hidden behind folds, appear flat against the colon lining, or be very small. During a lengthy examination, an additional visual alert may help the doctor notice an area that deserves closer inspection.

Research supports the potential of this technology. A 2024 randomized clinical trial involving more than 2,000 patients found that AI-assisted colonoscopy detected adenomas in 56.6% of participants, compared with 48.4% with standard colonoscopy. However, finding more adenomas does not automatically mean that AI reduces colorectal cancer deaths.

What are the potential benefits of AI-assisted colonoscopy?

AI-assisted detection may offer several advantages:

• Improved polyp detection: It can help identify additional adenomas during colonoscopy.

• An extra layer of visual support: The system can flag areas that warrant closer examination.

• Potentially fewer missed lesions: Research suggests AI may reduce the chance of overlooking adenomas, although results vary.

• Support for thorough examination: It may help the gastroenterologist maintain attention to the colon lining throughout the procedure.

The benefits depend on the quality of the examination, the AI system used, and the doctor's ability to assess the findings.

Does AI-assisted colonoscopy guarantee that polyps will be detected?

No. Although AI can support polyp detection, it cannot guarantee that every polyp will be found.

The technology may flag areas that are not polyps, and some lesions may not be recognized. AI also cannot compensate for inadequate bowel preparation, poor visibility, or an incomplete examination.

In addition, detecting more small polyps can sometimes lead to the removal and testing of growths that would never have become cancerous. Researchers continue to evaluate whether increased detection translates into meaningful improvements in long-term colorectal cancer outcomes.

A high-quality colonoscopy still depends on appropriate preparation, a complete examination, careful technique, and an experienced gastroenterologist.

Who should consider a colonoscopy?

Colonoscopy may be recommended for people who:

• Are due for colorectal cancer screening based on their age and individual risk.

• Have a family history of colorectal cancer or certain colorectal polyps.

• Have symptoms such as persistent changes in bowel habits, rectal bleeding, or unexplained iron-deficiency anemia.

• Need follow-up after previous polyps or colorectal cancer.

• Have inflammatory bowel disease and require appropriate surveillance.

The appropriate timing and type of examination depend on personal medical history, symptoms, family history, and local screening recommendations. AI availability should not determine whether someone needs screening.

The future of colonoscopy: combining medical expertise with technology

AI-assisted colonoscopy represents an important development in digestive health. By analyzing images in real time and highlighting suspicious areas, this technology may help gastroenterologists identify more colorectal polyps during examinations.

However, AI is a supporting tool, not a guarantee of cancer prevention. The most important elements remain appropriate screening, careful examination, and timely evaluation of any detected polyps.
