Endoscopic Ultrasound with Aspiration


  • The scope is inserted into the esophagus via a mouthpiece. 
  • The lymph nodes are visualized using ultrasound.
  • The aspiration needle is inserted through the work channel of the scope and by ultrasound guidance, into the lymph node.
  • Using back-and-forth movements with the needle, cells are sucked out of the lymph node.
  • The material is prepared and assessed by a cytologist.
  • The procedure can be repeated until representative material is obtained.
