The experts of Dongda Anorectal Hospital will use the international advanced painless technology of Korean anoscope and Japanese painless colonoscope for the examination of blood in stool. This equipment adopts medical video camera technology, so that both doctors and patients can clearly observe the lesions several times magnified at the same time during the examination process, and can also collect images of deep lesions inside the anus and intestines for real-time diagnosis, so that doctors and patients can clearly, accurately and intuitively understand the condition and help patients choose a treatment plan, avoiding delays caused by inadequacies brought about by traditional artificial examination. The examination time is short, only 3-5 minutes, but the accurate diagnosis rate is as high as 99% or more, effectively avoiding misdiagnosis and leakage, which is the cutting-edge equipment for the examination and diagnosis of anorectal disease internationally.
