Endoscopic Ultrasound (EUS) with FNA
Endoscopic Ultrasound (EUS) is a procedure that allows for diagnosis and staging of many cancers including lung, esophagus, stomach, pancreas, bile duct and rectum. In addition, EUS evaluates diseases of the lymph nodes of the chest, abdomen and pelvis, as well as masses in the liver.
EUS is a minimally invasive procedure that provides an extremely detailed ultrasound evaluation of the anatomy around the upper and lower GI tract. Fine Needle Aspiration (FNA) biopsy of lesions in the chest, abdomen and pelvis are also possible with this technology. This state-of-the-art advancement allows for rapid visual evaluation and diagnostic biopsies of primary tumors and metastatic disease to allow patients to confidently move forward with appropriate surgical, chemotherapeutic or radiation therapies. EUS/FNA complements, and in many cases replaces, previously used imaging studies and procedures that are either more invasive or less sensitive. Accurate staging diagnoses made by EUS/FNA are extremely critical in providing optimal cancer care.
Endobronchial Ultrasound (EBUS) is a minimally invasive procedure designed to help surgeons and pulmonologists accurately stage lung cancers and diagnose other thoracic disorders. Garnet Health Medical Center introduced this innovative technology as part of our lung cancer program in 2011, enhancing our ability to stage cancer and provide an accurate treatment plan without an invasive incision.
This procedure utilizes a specialized bronchoscope that incorporates an ultrasound probe allowing the surgeon to visualize lymph nodes in the chest. A critical step in formulating a treatment plan for the patient is determining whether these lymph nodes contain cancer cells. The scope has a transbronchial needle that is passed through the wall of the airway guided by the ultrasound image to obtain tissues samples of the target lymph nodes. A pathologist accompanies the surgeon in the operating room to provide an instant and accurate assessment of the tissue samples.
This procedure replaces mediastinoscopy, which is also performed to biopsy these lymph nodes, however it requires a small incision at the base of the neck to insert a scope.
In addition diagnosis and staging of lung cancer with this procedure, other disorders, such as lymphoma and sarcodosis, can be easily detected in the chest without the need for an incision.
