Rectoscopy is an examination which enables the doctor to directly view the mucous membrane of the anus and the last part of the large intestine (the so-called colon). The examination is performed with the use of a proctoscope, which is an instrument equipped with a video camera to view the image from the inside of the body. An important benefit of the proctoscope is the ability to evaluate the state of the mucous membrane as well as to collect a small sample of the tissue which is suspected to have lesions for further procedures, and all this during only one procedure. 

Indications for rectoscopy:

  • suspected early state of development of anal cancer and colorectal cancer
  • suspected precancerous state in the form of polyps
  • ulcerative colitis
  • diverticulosis
  • endometriosis
  • pain in the lumbar spine and in the sacral region
  • establishing the reasons for bleeding, diarrhoea, chronic constipation

There is no need to perform additional examinations.
