Endoscopies can be uncomfortable and invasive, requiring anesthesia and time off work. In emergencies, endoscopies cannot be performed in the emergency room and only by a specialist. However, researchers at George Washington University (GW) have investigated a new technology called NaviCam, a robotic capsule camera that can be precisely controlled using a magnetic field. AnX Robotica developed the product, and it is the first time that capsules have been tested in a study in the United States.
The capsule can be swallowed and move painlessly inside the body, wirelessly transmitting images to the outside world. The capsule is controlled by an external magnetic field, which means that a skilled operator is required. However, the team is already working on handing over control to an artificial intelligence (AI) in the future, making it easier to screen and diagnose patients.
Scientists conducted a study with 40 patients who preferred capsule endoscopy to a conventional endoscopy procedure because the method was less invasive. However, a larger study is required to confirm the results and ensure that no significant lesions are missed. Also, the capsule camera is good at detecting lesions, but a biopsy cannot be performed at the same time. The conventional method is still better in this regard but is less preferred due to its invasiveness.
Despite some limitations, this development has the potential to make screenings and diagnoses easier for staff in specialist practices and emergency rooms. It could also save time and reduce the need for anesthesia, making the process more patient-friendly.
