Substernal thyroid lesions are common, and need to be differentiated from malignancy. Obtaining percutaneous fine needle biopsy is not possible due to its retrosternal location. This article proposes a protocol for biopsy of substernal thyroid lesions using Endobronchial Ultrasound-guided Transbronchial Needle Aspiration (EBUS-TBNA).

Practicing of fine needle aspiration biopsies (FNAB) by trainees is relatively challenging, due to the lack of an easily available, appropriate lesion. Preparation of an AV phantom lesion for practicing the FNAB procedure and mastering proficiency is relatively easy.

Using the Endoscope for Endobronchial Ultrasound in the Esophagus

Transesophageal ultrasound (EUS-B) is a safe and feasible procedure using the echoendobronchoscope (EBUS) in esophagus and stomach. After identifying six anatomical landmarks, additional structures can be identified and biopsied, sparing subsequent diagnostic sessions. Thus, EUS-B is an ideal continuation of bronchoscopy and EBUS in diagnosing lung cancer and other diseases.
FAQs
The ultrasound component sends imaging beyond the bronchial wall, allowing the operator to see nearby lymph nodes and masses that are not directly visible within the airway. This real-time view helps align the fine needle with the intended target before it passes through the airway wall, supporting focused collection of cellular or tissue material.
Real-time imaging connects the visualized target with the needle’s path during the procedure. Instead of collecting material without knowing the exact relationship between the airway and adjacent structures, the operator can direct sampling toward a selected lymph node or mass. This targeted approach is particularly relevant when evaluating mediastinal or hilar abnormalities.
The needle collects cells or tissue from a targeted lesion, and that material can be examined cytologically, meaning through cellular analysis, as well as molecularly. These complementary assessments can provide diagnostic information and support treatment planning in lung cancer, where both disease identification and characterization may be clinically important.
The procedure begins with bronchoscopy using an endoscope equipped with ultrasound. The operator identifies a lymph node or mass beyond the bronchial wall, then advances a fine needle through that wall into the selected target. Collected cells or tissue are subsequently available for cytologic and molecular analysis.
In lung cancer, EBUS-TBNA is used primarily for diagnosis and staging. Sampling a nearby lymph node or mass can help determine whether the suspected disease is present and evaluate its regional extent. The resulting information can contribute to treatment planning while potentially reducing the need for a more invasive surgical procedure.
EBUS-TBNA can investigate mediastinal or hilar lymphadenopathy, meaning enlarged lymph nodes in areas between the lungs or near the lung roots, when infection or inflammatory disease is suspected. Sampling these nodes provides cellular or tissue material for analysis, helping clinicians investigate causes of enlargement beyond malignant disease.
