Endoscopy is widely used in gastrointestinal investigations. It has been enhanced now by AI and ML. Software that can detect and flag abnormalities in the GI tract is being used. The machine is fed with thousands of images of cancerous growths and it learns over a period of time to detect such growths accurately. Such growths are recognised by the computer and an alert is given. Earlier detection is an advantage. The software does this by using computer vision. At present, this is used to detect colonic cancer but in future this can be extended to include different parts of the body such as stomach, liver and pancreas. Already, AI is being used in ophthalmology, radiology and dermatology. These are early days in gastro-enterology. The first such device has been approved in April 2021. Many more trials are happening. Many more such devices will be approved in future.
