Chulalongkorn University develops AI tool to detect colorectal polyps

Researchers from Chulalongkorn University, a public university in Thailand, have created an AI-based system to detect digestive disorders.


According to Dr. Peerapon Vateekul, a member of the research team from Chula Engineering, DeepGI (Deep GI Technology) detects abnormal tissue indicative of early colon cancer, such as polyps, in the colon. with more than 90% accuracy.

The software uses deep learning, a machine learning technique, and is trained using colonoscopy data imaging collected since 2019 with the support of Chulalongkorn University Technology Center and ESM Solutions Co. .

The system can also generate a characterization of detected polyps and identify them as cancerous (malignant) or hyperplastic (benign) without the need for a biopsy.


Colorectal cancer is the third most common cancer in Thais. About 15 million seniors aged 50 and over are thought to be at risk. Unfortunately, only about a thousand endoscopists who are willing to have a colonoscopy.

In addition, current standard approaches to colorectal cancer diagnosis including colonoscopy or lower GI endoscopy, the researchers say, have shown limitations due to other forms of polyps. different in shape, size and color. They note that up to 22% of tests can fail.

Dr Peerapon hopes that their AI polyp detection tool will be “widely used as an aid to endoscopists practicing in other hospitals, especially in the community setting.” there is a shortage of medical and technological manpower”.

This technology has been applied to actual patients at King Chulalongkorn Memorial Hospital since late last year.

In addition to vendor agnostic capabilities, DeepGI can also be extended to detect biopsies of abnormalities in other parts of the human body. Dr. Peerapon shared that their team is looking to test this system in other organs, such as the stomach and biliary tract.

The team is currently in the process of applying for a national patent for their polyp detection software.


The past year has seen several releases of new AI-powered tools for diagnostics gastrointestinal abnormal.

Chinese startup Wision AI in November received CE marking to launch its AI polyp detection software EndoScreener in Europe.

Japanese electronics company NEC has released in Japan its own AI diagnostic aid Endoscopy WISE VISION that also automatically flags potential damage in the colon.
