UK Rolls Out Pill-Sized Colonoscopy Alternative That's Less Invasive, More Convenient

The U.K. is testing out pill-sized cameras that patients can simply swallow as a less invasive way to test for cancer.

Colonoscopies are typically required to check for certain cancers. However, it requires inserting a long tube with a camera at the tip of it into the rectum so the procedure tends to be uncomfortable for many patients, the Mayo Clinic explained. What's more, it can take a full day for a patient to recover from the sedative used in the procedure.

In the U.K., the National Health Service (NHS) is rolling out a less invasive alternative for colonoscopies.

Called the colon capsule endoscopy, the test can detect abnormalities but the patient needs to swallow only a small capsule that contains a tiny camera. The images it takes are then transmitted to a data device that the patient can simply carry around in a shoulder bag, the NHS explained.

This means that compared to a traditional colonoscopy, the patient can go about their normal day while the capsule does its job.

Further, the simpler procedure also would allow more people to get the test done. Because of COVID-19, endoscopies have taken longer to do because they need to be "COVID secure," the NHS explained.

Through the colon capsule endoscopy, more patients can take the life-saving test without having to use hospital space. This means that even those who may be hesitant to go to the hospital can still get the test they need, clinical lead Ed Seward said.

"The cameras will help to speed up the checks, catching more cancers early when they are easier to treat," the NHS said.

So far, 11,000 NHS patients from 40 parts of the country are set to receive the test. And apart from cancers, it can also look for signs of other conditions such as Crohn's Disease, NHS Chief Executive Sir Simon Stevens noted.

"From the cutting edge technology of these colon capsules to COVID protected hubs and chemo home deliveries, the NHS has fast-tracked new ways of treating and diagnosing cancer – all while responding to the coronavirus pandemic," Professor Peter Johnson, NHS clinical director for cancer, said.

"The NHS message to anyone experiencing symptoms is clear – do not delay, help us to help you by coming forward for care – the NHS is ready and able to treat you," he added.
