Kits and reagents for detecting adenomas and CRC and/or drug screening are also part of the invention.

A self propelled, endoscopic apparatus formed of a flexible, fluid-filled toroid and a motorized or powerable frame. The apparatus may be used to advance a variety of accessory devices into generally tubular spaces and environments for medical and non-medical applications. The apparatus when inserted into a tubular space or environment, such as the colon of a patient undergoing a colonoscopy, is advanced by the motion of the toroid. The toroid's surface circulates around itself in a continuous motion from inside its central cavity along its central axis to the outside where its surface travels in the opposite direction until it again rotates into its central cavity. As the device advances within the varying sizes, shapes and contours of body lumens, the toroid compresses and expands to accommodate and navigate the environment. The motion of the toroid can be powered or unpowered and the direction and speed may be controlled. The apparatus may be used to transport a variety of accessory devices to desired locations within tubular spaces and environments where medical and non-medical procedures may be performed.

A method for suppressing tagged material in prepless colonoscopy includes identifying and segmenting multiple density classes, intensity classes, or both in a volumetric medical image of a patient including a volume of the patient's colon and classifying the volume of the patient's colon into a plurality of types based upon the identified and segmented density classes, intensity classes, or both. The method further includes subtracting, suppressing, or leaving the tagged material in the image in accordance with the type classifications to produce a resulting image and visualizing the resulting image.

The invention relates to a method of screening a patient to identify and quantify risk of colorectal cancer, and thereby identify patients suitable for further invasive investigation such as a colonoscopy. The method employs auto-antibodies that are shown to correlate with colorectal cancer risk method and involves of assaying a biological sample from the individual for a combination of a plurality of biomarkers selected from SEQUENCE ID NO's: 1 to 12, where the combination of biomarkers is chosen such that detection of all biomarkers in the patient correlates to at least a 50% risk of the patient being positive for colorectal cancer. Detection of all of the combination of biomarkers indicates that the patient should undergo a colonoscopy. Kits for performing the method of the invention are also provided.

The invention relates to an intelligent colonoscopy and belongs to intelligent electronic medical instruments. A gastrointestinal endoscope is a very indispensable and important instrument for routine examination of digestive tract diseases. However, an existing colonoscopy has no digestive tract intervening operation function and is manually operated to cause harm to a patient. Due to the facts that the physical performance of the contact face between the colonoscopy and the inner wall of the gastrointestinal tract is improved and the friction coefficients between the colonoscopy and the inner wall of the gastrointestinal tract are increased, the colonoscopy can acquire safe, stable and reliable running power in the gastrointestinal tract. The self-adaptive curve of the colonoscopy corresponds to the curve of the gastrointestinal tract, so that scientific and accurate colonoscopy examination can be smoothly and conveniently finished in the situation without any pain risk for the patient. Thus, the medical safety is guaranteed, and the medical quality is improved.

The invention provides a system and a method for monitoring a blind area under an enteroscope. The system reminds a doctor of slipping of the enteroscope actively, and urges the doctor to return the enteroscope in place, so that the enteroscopy covers all parts in the enteric cavity. The method mainly includes the following steps: acquiring images by an enteroscope device, sending the collected colonoscopy images to a client side and a server side, receiving the colonoscopy images as parameters by the server side, calling a convolutional neural network model to identify the images of enteroscope slipping, calling a perceptual Hash algorithm to judge whether the enteroscope is returned successfully or not, and displaying the result on the client side. The system and the method have the advantages that a reliable reference point is provided to an operator, detection comprehensiveness and effectiveness are improved, the system is simple and easy to use, and patients are prevented from suffering from secondary pain due to the fact that correct detection is not conducted at a time.
