What Is a Proctoscopy?

The rectum and sigmoid colon are the ends of the digestive tract and are also the sites of polyps, ulcers, and malignancies. Rectal adenomatous polyps are also precancerous lesions. Familial multiple polyposis is often susceptible to cancerous changes, even with multiple cancerous changes, and the rate of canceration can be as high as 15% -60%. Ulcerative colitis is also a common cause of cancerous changes. Malignant tumors occur most often at the junction of the rectum and the sigmoid colon, accounting for 15% of systemic malignancies, 75% of colon cancers, and about half occur in the rectum. Patients with malignant tumors of the rectum and sigmoid colon often have changes in bowel habits and blood in the stool, and are often misdiagnosed as dysentery and hemorrhoids, which brings serious consequences to patients.

Colonoscopy uses a fiber tube with a length of about 140CM that can be bent and a light source with a microelectronic camera at the end. It is slowly entered from the anus into the large intestine to check for lesions, tumors or ulcers in the large intestine. If necessary, tissue Examination or Resection of Colon Polyps
