Rectoscopy is also known as an endoscopy of the rectum. During the examination, the patient is in the knee-elbow position or lying on his side. The doctor inserts a camera with a light source (rectoscope) through the anus. Thanks to covering the speculum with an anesthetic, the examination is very well tolerated by the patient. The diagnostic procedure of rectoscopy enables the detection of pathological changes in the intestinal wall, such as polyps, diverticula, ulcers and colorectal cancer. Rectoscopy also allows you to remove the detected lesions and stop any bleeding.
