Rectoscopy with fine needle biopsy

Implementation

  • Before endoscopy, a thorough exploration is performed.
  • The rectoscope is lubricated and inserted into the rectum.
  • The stick in the rectoscope used to ease insertion is removed.
  • The scope is inserted further into the bowel.  
  • Air is inflated into the bowel to improve overview.
  • If needed, surface or fine needle biopsies are taken. 
  • The biopsy needle is inserted into the lesion along the finger
  • When the biopsy needle is released, the mandrin is first released followed by the needle 2.5 cm forward.
  • The biopsy remains in a notch in the mandrin.
  • The scope is retrieved with circular movements such that the entire bowel is inpected. Be aware of the "blind zone" behind.
  • The exam takes about 5 minutes.
