How is Proctitis investigated?

After taking a detailed clinical history in the clinic further tests are required.
Tests are required to confirm the diagnosis, and assess the extent and severity of the proctitis. As well as the visual appearance of the bowel, proctitis is confirmed by the microscopic examination of tissue samples (biopsies) taken from the bowel.

  • Rigid sigmoidoscopy - will be carried out in clinic. This test allows the doctor to look at the lining of the lowest part of the bowel by passing a small tube via the back passage.
  • Colonoscopy - this allows the inside of the colon and rectum to be examined through a long flexible tube being inserted via the back passage and up into the colon. This test can be used to determine the amount of inflammation inside the rectum and colon.  During the colonoscopy biopsies can be taken to help with confirm a diagnosis.
  • Flexible sigmoidoscopy - this allows the doctor to look at the lower part of the bowel using a shorter flexible tube inserted via the back passage. Again inflammation can be assessed and biopsies taken. The whole of the colon is not seen using this test.
  • Blood tests- blood tests may be taken to assess the severity of inflammation.
  • Stool tests- in patients with diarrhoea, these are required to identify whether or not there is an underlying infection causing the symptoms.
