What Are the Risks and Complications of a Rectal Biopsy?

While a rectal biopsy is generally safe, it carries some risks and potential complications, including:

  • Bleeding: Mild bleeding at the biopsy site is common, but significant bleeding is rare.
  • Infection: There is a small risk of infection at the biopsy site.
  • Pain and Discomfort: Some patients may experience mild pain or discomfort during or after the procedure, which usually resolves quickly.
  • Perforation: Rarely, the procedure may cause a tear (perforation) in the rectal wall.
  • Reaction to Anesthesia: If sedation or anesthesia is used, there is a risk of adverse reactions.
