Electronic anoscopy, is currently recognized internationally as a more excellent anorectal imaging inspection system, using medical video camera technology, breaking the drawbacks of the traditional anoscopy, doctors and patients in the inspection process can be observed at the same time to the lesion site, and can be locked after the lesion print imaging, can also be enlarged to observe the deep lesions of the internal anus and intestines can be captured images of the lesion site, real-time diagnosis, so that doctors and patients clearly, accurately, intuitively understand the It allows doctors and patients to understand the disease clearly, accurately and intuitively, avoiding misdiagnosis and omission of diagnosis. At the same time for comparison before and after treatment to provide a reliable basis to help patients understand the condition of the choice of treatment program, to avoid delays due to the inadequacy of the traditional man-made examination of the condition caused by the delay. At the same time with minimally invasive painless technology to treat various types of hemorrhoids, anal fistula disease, can achieve a cure. Those who should do electronic anoscopy: 1, the diagnosis and differential diagnosis of hemorrhoids. 2, the cause of blood in the stool is unknown need to determine the cause of blood. 2, blood in stool of unknown cause need to determine. 3, anal fistula and hemorrhoids classification and typing. 4, hemorrhoids preoperative preparation to determine the treatment plan. 5.Provide reference basis for surgical treatment program. 6.Hemorrhoids postoperative review to determine the effect of surgery. 7.The analysis and judgment of unknown mass. Four advantages of electronic anoscopy: high-definition imaging: electronic anoscopy will be the international advanced medical video, camera technology complete combination into one, creating a new era of deep source inspection and treatment of anus and intestines. Intelligent examination: digital color screen display, the image can be fixed, stored, reproduced, can be used for comparison before and after treatment, color printing results, medical records management, query. Interactive diagnosis and treatment: doctors and patients clearly, accurately and intuitively understand the condition, avoid misdiagnosis and mistreatment, and provide a reliable basis for clinical treatment. Precise and in-depth: it can collect and diagnose the deep lesions inside the anus and intestines in real time, breaking the drawbacks of traditional anoscopy and anal fingerprinting which are easy to misdiagnose.
