Integrated with bronchoscopy, this technique provides high diagnostic accuracy, particularly in lung cancer staging and the assessment of mediastinal lesions.<\/p>\n<p>In response to the question of how the EBUS procedure is performed, the examination is carried out under sedation using a specialized bronchoscope inserted through the mouth. Thanks to the ultrasound probe located at the tip of the device, the tissues surrounding the airways are visualized in real time, and when necessary, fine-needle aspiration biopsy is performed for pathological examination.<\/p>\n<p>Regarding the diseases in which EBUS is used, it plays an effective role in the diagnosis and staging of conditions such as lung cancer, lymphoma, sarcoidosis, and mediastinal lymphadenopathy. In particular, the ability to obtain samples from lymph nodes without the need for surgery contributes to the accurate determination of disease spread.<\/p>\n<p>When evaluating the advantages and risks of EBUS, its low complication rate and high diagnostic accuracy are among its greatest strengths. Mild sore throat or, rarely, bleeding may occur after the procedure. Because it is less invasive than surgical mediastinoscopy, it is widely preferred in clinical practice.<\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_89 counter-hierarchy ez-toc-counter

class=\"ez-toc-section\" id=\"How_Does_Endobronchial_Ultrasound_EBUS_Work\"><\/span>How Does Endobronchial Ultrasound (EBUS) Work?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The traditional bronchoscopy method, which has been used for many years to examine the inside of the airways, is similar to walking through a tunnel while illuminating it with a flashlight. With this method, only the tunnel walls\u2014that is, the inner surface of the airways\u2014can be seen. However, a large proportion of diseases affecting the lungs and thoracic cavity begin behind these walls or spread to these hidden areas. Endobronchial Ultrasound (EBUS) technology completely overcomes this limitation by placing a miniature ultrasound device at the tip of a standard bronchoscope.<\/p>\n<p>As the device advances through the airways, the ultrasound probe at its tip emits high-frequency sound waves. Similar to the sonar systems used by submarines for navigation or the echolocation mechanisms that allow bats to fly in the dark, these sound waves strike tissues and return as echoes. The returning waves are instantly displayed on a high-resolution screen, creating a black-and-white map of the structures behind the airway wall. This map clearly distinguishes lymph nodes, masses, tumors, and adjacent vital blood vessels such as the heart and aorta that cannot be seen with the naked eye. Moreover, this technology does more than visualize these structures; under ultrasound guidance, a very fine needle passed through the device can enter the targeted tissue and obtain cellular samples. Since the movement of the needle is monitored on the screen in real time, the risk of entering the wrong area or damaging blood vessels is almost completely eliminated.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_Types_of_Endobronchial_Ultrasound_EBUS_Devices_Are_Available\"><\/span>What Types of Endobronchial Ultrasound (EBUS) Devices Are Available?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The physical characteristics of the device used vary depending on the type of disease, its location, and the anatomical structure of the airways. According to their technological design and intended use, these systems are divided into two main groups.<\/p>\n<p>The primary types of devices used in medical practice are:<\/p>\n<ul>\n<li>Linear probe<\/li>\n<li>Radial probe<\/li>\n<\/ul>\n<p>The linear (convex) probe is generally used to examine large structures surrounding the trachea and major airways. This system projects ultrasound images onto the screen in a linear fan-shaped plane. It has a dedicated working channel through which the biopsy needle is advanced. As the needle enters the tissue, both the tissue itself and the needle tip are simultaneously visible on the screen, providing the physician with exceptional procedural control. The radial probe, on the other hand, is much thinner\u2014about the thickness of a strand of spaghetti\u2014and is designed to detect small lesions located in the peripheral regions of the lungs, far from the major airways. This slender probe is advanced into narrow airways and emits a 360-degree circular ultrasound beam, producing a complete radar-like image of the surrounding tissue. Once the suspicious lesion is identified, the probe is withdrawn and specialized instruments are advanced through the same pathway to obtain tissue samples.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Which_Areas_Can_Be_Reached_with_Endobronchial_Ultrasound_EBUS\"><\/span>Which Areas Can Be Reached with Endobronchial Ultrasound (EBUS)?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The region located in the center of the chest between the two lungs, containing the heart, major blood vessels, esophagus, and trachea, is called the mediastinum.<\/p>\n<p>This region is also extremely rich in lymph nodes, which function as the body&#8217;s immune defense stations. Diseases affecting the lungs or other organs often wage their cellular battle within these lymph nodes. Therefore, accessing these lymph nodes is essential for establishing a diagnosis.<\/p>\n<p>The main anatomical locations that can be safely reached and sampled using this method include:<\/p>\n<ul>\n<li>Upper paratracheal lymph nodes<\/li>\n<li>Lower paratracheal lymph nodes<\/li>\n<li>Subcarinal lymph nodes<\/li>\n<li>Hilar lymph nodes<\/li>\n<li>Interlobar lymph nodes<\/li>\n<\/ul>\n<p>The paratracheal lymph nodes located on either side of the trachea and the broad subcarinal region situated just below the point where the trachea divides into the right and left main bronchi are among the areas where this device provides the highest-quality imaging. Even lymph nodes adjacent to the aortic arch, which are considered difficult and risky to access through conventional surgery, can be safely reached with this flexible and maneuverable device. Furthermore, thanks to the Doppler mode, which displays blood flow in color, even tiny blood vessels surrounding the target lymph node can be identified, allowing the biopsy needle to be safely guided between them.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Why_Is_Endobronchial_Ultrasound_EBUS_Critical_in_the_Diagnosis_of_Lung_Cancer\"><\/span>Why Is Endobronchial Ultrasound (EBUS) Critical in the Diagnosis of Lung Cancer?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>When lung cancer is suspected, identifying the disease alone is not sufficient for determining the most appropriate treatment plan. It is equally important to establish the stage of the disease\u2014that is, the extent of its spread within the body. Positron Emission Tomography-Computed Tomography (PET-CT), commonly used for staging, highlights rapidly metabolizing cells with increased glucose uptake. However, increased uptake does not always indicate cancer. Simple infections, previous pneumonia, or benign inflammatory reactions may produce PET findings identical to those of cancer.<\/p>\n<p>For this reason, regardless of how suspicious lymph nodes appear on imaging, the presence of cancer cells must always be confirmed through microscopic examination. This is where Endobronchial Ultrasound (EBUS) becomes indispensable. Tiny cellular samples obtained during the procedure are analyzed in the laboratory. If the samples are negative for cancer, it indicates that the disease has not spread beyond the lung, allowing the patient to proceed directly to potentially curative surgery. However, if cancer cells are detected in the lymph nodes, it confirms disease spread. In such cases, chemotherapy or radiotherapy is generally initiated before surgery to reduce tumor burden and control the disease. Therefore, EBUS serves as the most important decision-making tool in preventing unnecessary major surgery.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_Is_Endobronchial_Ultrasound_EBUS_Used_in_Sarcoidosis\"><\/span>How Is Endobronchial Ultrasound (EBUS) Used in Sarcoidosis?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Enlargement of lymph nodes within the chest does not always indicate cancer. Benign diseases such as sarcoidosis, which results from an abnormal immune response affecting the lungs and intrathoracic lymph nodes, are also common. Patients with sarcoidosis frequently develop enlarged lymph nodes around both lung hila and the trachea. Radiologically, this pattern often resembles lymphoma or lung cancer, making tissue sampling essential for definitive diagnosis.<\/p>\n<p>The diagnosis of sarcoidosis depends on identifying characteristic microscopic structures within the biopsy specimen. In the past, patients required surgery under general anesthesia involving a neck incision to obtain this diagnosis. Today, thanks to this advanced technology, patients can undergo the procedure under mild sedation without any surgical incision. Cellular material aspirated from the lymph node is sent to the laboratory, where the characteristic cell clusters of sarcoidosis are rapidly identified. This approach not only relieves patients from the fear of cancer but also spares them from unnecessary surgical complications.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_Is_the_Role_of_Endobronchial_Ultrasound_EBUS_in_the_Diagnosis_of_Tuberculosis\"><\/span>What Is the Role of Endobronchial Ultrasound (EBUS) in the Diagnosis of Tuberculosis?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Tuberculosis (TB), commonly known as consumption, not only damages lung tissue but can also spread to the deep mediastinal lymph nodes, where it may silently multiply. Especially in regions where tuberculosis is prevalent, enlarged mediastinal lymph nodes or thoracic masses should raise suspicion for this infection.<\/p>\n<p>Detecting Mycobacterium tuberculosis is not always straightforward. Standard sputum tests are often insufficient. Definitive diagnosis requires obtaining tissue directly from the infected lymph node and culturing it under specialized laboratory conditions. Endobronchial Ultrasound (EBUS) advances through the airways within a completely enclosed sterile system, minimizing the risk of spreading infection to surrounding tissues. Adequate fluid and tissue samples are collected directly from the infected lymph node. These specimens not only confirm tuberculosis but also allow determination of antibiotic susceptibility and resistance, enabling physicians to initiate the most effective treatment.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Is_Endobronchial_Ultrasound_EBUS_Effective_in_Detecting_the_Spread_of_Other_Cancers\"><\/span>Is Endobronchial Ultrasound (EBUS) Effective in Detecting the Spread of Other Cancers?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>As the central hub of blood and lymphatic circulation, the lungs are unfortunately among the most common destinations for metastases originating from other organs. For example, patients with a history of breast, colorectal, kidney, prostate, or stomach cancer may develop a new lung or mediastinal lesion years later.<\/p>\n<p>At this stage, the most critical question is whether the new lesion represents metastasis from the previous cancer or an entirely new primary lung cancer. Since treatment protocols differ completely, making this distinction accurately is essential. Thanks to the safe access provided by EBUS, cellular samples can be obtained from these suspicious lesions. In pathology laboratories, highly specialized immunohistochemical stains are applied to determine the cellular origin and identify the primary organ from which the tumor arose. This precise diagnosis enables medical oncologists to select the most appropriate targeted therapy, chemotherapy, or immunotherapy without delay.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_Are_the_Advantages_of_Endobronchial_Ultrasound_EBUS_Compared_with_Traditional_Surgery\"><\/span>What Are the Advantages of Endobronchial Ultrasound (EBUS) Compared with Traditional Surgery?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>For many years, the gold standard for evaluating mediastinal lymph nodes was the surgical procedure known as mediastinoscopy. This required the patient to undergo general anesthesia, a neck incision, and insertion of surgical instruments behind the sternum. The procedure involved postoperative wound care, infection risk, possible injury to the recurrent laryngeal nerve, and hospitalization.<\/p>\n<p>The advantages of modern ultrasound-guided airway examination include:<\/p>\n<ul>\n<li>No surgical incision<\/li>\n<li>No sutures<\/li>\n<li>No surgical scar<\/li>\n<li>Same-day discharge<\/li>\n<li>Low risk of infection<\/li>\n<li>No mandatory general anesthesia<\/li>\n<\/ul>\n<p>With this modern technology, the airways are accessed naturally through the mouth or nose. Since the procedure is performed entirely within a closed system, no surgical incision or tissue trauma occurs. General anesthesia is usually unnecessary, as mild sedation provides sufficient patient comfort. Recovery is rapid, allowing patients to resume eating and drinking within a few hours and return home the same day. Scientific studies have demonstrated that the diagnostic accuracy of this comfortable technique is comparable to, and in some anatomical regions even superior to, traditional surgical methods.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_Does_the_Preparation_Process_Before_Endobronchial_Ultrasound_EBUS_Progress\"><\/span>How Does the Preparation Process Before Endobronchial Ultrasound (EBUS) Progress?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Successful, comfortable, and safe performance of the procedure depends on meticulous preparation. This stage is not only for completing medical evaluations but also for reassuring the patient and answering all questions. The patient&#8217;s overall health, previous illnesses, surgeries, medication allergies, and imaging studies such as CT or PET scans are carefully reviewed to plan the procedure.<\/p>\n<p>The essential pre-procedural tests include:<\/p>\n<ul>\n<li>Complete blood count<\/li>\n<li>Coagulation profile<\/li>\n<li>Kidney function tests<\/li>\n<li>Liver enzyme tests<\/li>\n<li>Electrocardiogram (ECG)<\/li>\n<li>Pulmonary function tests<\/li>\n<\/ul>\n<p>These tests determine whether hidden infections are present, whether kidney function is adequate for medication metabolism, and whether the heart can safely tolerate sedation. Fasting is essential for safety. Patients are instructed not to eat or drink anything, including water, for at least six to eight hours before the procedure to prevent aspiration of stomach contents during sedation.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_Is_Medication_Managed_Before_Endobronchial_Ultrasound_EBUS\"><\/span>How Is Medication Managed Before Endobronchial Ultrasound (EBUS)?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Thanks to advances in medical treatment, many individuals now regularly use blood-thinning medications because of heart valve disease, cardiac rhythm disorders, coronary stents, or stroke prevention. Since fine-needle aspiration is performed through the airway wall during EBUS, normal blood clotting is essential. Excessive anticoagulation may lead to bleeding that is difficult to control.<\/p>\n<p>The medications that may need to be discontinued or adjusted before the procedure include:<\/p>\n<ul>\n<li>Warfarin<\/li>\n<li>Clopidogrel<\/li>\n<li>Prasugrel<\/li>\n<li>Ticagrelor<\/li>\n<li>Rivaroxaban<\/li>\n<li>Apixaban<\/li>\n<li>Acetylsalicylic acid<\/li>\n<li>Heparin derivatives<\/li>\n<\/ul>\n<p>Management of these medications is never left to the patient&#8217;s discretion. Instead, an individualized plan is created in consultation with cardiology or internal medicine specialists to ensure cardiovascular safety. Some medications require discontinuation one week before the procedure, whereas others require only a brief interruption. When necessary, long-acting oral anticoagulants are temporarily replaced with short-acting injectable agents to maximize patient safety.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_Is_Anesthesia_Administered_During_Endobronchial_Ultrasound_EBUS\"><\/span>How Is Anesthesia Administered During Endobronchial Ultrasound (EBUS)?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The throat and trachea are protected by highly sensitive nerves responsible for the cough and gag reflexes. Introducing a bronchoscope into an awake patient naturally triggers these reflexes, making the procedure impossible. Therefore, specialized anesthesia techniques are used to ensure a comfortable experience for both the patient and the physician.<\/p>\n<p>The procedure is generally performed under conscious sedation, creating a highly comfortable sleep-like state. Short-acting intravenous medications provide deep relaxation. During this period, patients remain asleep, experience no pain or breathing discomfort, hear nothing occurring around them, and remember nothing afterward. Unlike general anesthesia used in major surgery, conscious sedation does not require mechanical ventilation, and patients continue breathing spontaneously. In addition, local anesthetic sprays containing lidocaine are applied to the throat and upper airway, allowing the bronchoscope to pass smoothly with minimal stimulation.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_Are_the_Biopsy_Steps_During_Endobronchial_Ultrasound_EBUS\"><\/span>What Are the Biopsy Steps During Endobronchial Ultrasound (EBUS)?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>After the patient is sedated and all safety measures are confirmed, the procedure begins. The flexible bronchoscope is usually inserted through the mouth using a protective bite block and advanced gently into the trachea. A standard bronchoscopic examination is first performed to inspect the airway for redness, narrowing, or visible tumors. The system is then switched to ultrasound mode.<\/p>\n<p>A small balloon located at the tip of the bronchoscope is inflated with sterile water. Since sound waves do not travel efficiently through air, this water-filled balloon ensures close contact between the probe and the airway wall, providing optimal ultrasound transmission. The screen immediately displays a black-and-white radar-like image. Once the target lymph node is identified, its size is measured and nearby blood vessels are mapped using Doppler imaging. A thin flexible needle is then advanced through the bronchoscope. Its entry into the lymph node is monitored in real time. While inside the node, gentle back-and-forth movements combined with suction collect cellular material into the needle. In advanced centers, these samples are immediately examined by an on-site pathologist, who determines whether sufficient material has been obtained for diagnosis. If adequate, the procedure is successfully completed.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_Happens_During_Recovery_After_Endobronchial_Ultrasound_EBUS\"><\/span>What Happens During Recovery After Endobronchial Ultrasound (EBUS)?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Once sampling is completed, the bronchoscope is gently removed and the patient is transferred to a recovery area. The sedative medications usually wear off within ten to fifteen minutes, and the patient awakens. Blood pressure, heart rate, and oxygen saturation are monitored closely for several hours.<\/p>\n<p>The main recommendations after returning home include:<\/p>\n<ul>\n<li>Do not drive<\/li>\n<li>Do not sign important documents<\/li>\n<li>Avoid activities requiring concentration<\/li>\n<li>Avoid extremely hot or cold foods<\/li>\n<li>Remain with a responsible companion<\/li>\n<li>Drink plenty of water<\/li>\n<\/ul>\n<p>The effect of the throat-numbing spray generally lasts for about two hours. During this period, patients should avoid eating or drinking to prevent aspiration. After swallowing function has returned, fluids may gradually be introduced. Because the procedure is performed on an outpatient basis, patients are discharged the same day after a brief observation period. However, due to the lingering effects of sedation, they should not drive or make important decisions until the following day, when they may resume their normal daily activities without restriction.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"What_Are_the_Possible_Side_Effects_of_Endobronchial_Ultrasound_EBUS\"><\/span>What Are the Possible Side Effects of Endobronchial Ultrasound (EBUS)?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>As a minimally invasive procedure, EBUS has an exceptionally favorable safety profile. It has been safely performed in millions of patients worldwide and does not carry the significant risks associated with major surgery. Nevertheless, insertion of a bronchoscope and needle sampling may produce several mild and expected side effects.<\/p>\n<p>Temporary symptoms that may occur after the procedure include:<\/p>\n<ul>\n<li>Mild sore throat<\/li>\n<li>Hoarseness<\/li>\n<li>Dry cough<\/li>\n<li>Small amounts of blood in saliva<\/li>\n<li>Mild fever<\/li>\n<li>Discomfort while swallowing<\/li>\n<\/ul>\n<p>These symptoms generally resolve spontaneously within twenty-four to forty-eight hours without medical intervention. Slight blood streaks in sputum due to tiny ruptured capillaries are common and should not be a cause for concern. Rare complications such as pneumothorax or infection have been reported at extremely low rates, but with modern ultrasound guidance and experienced physicians, these risks are rarely encountered in clinical practice.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"How_Are_Samples_Obtained_by_Endobronchial_Ultrasound_EBUS_Examined\"><\/span>How Are Samples Obtained by Endobronchial Ultrasound (EBUS) Examined?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The tiny cellular samples collected during the procedure contain an enormous amount of information that guides future treatment. After being preserved in specialized solutions, they undergo advanced laboratory analysis. The cells are stained, mounted on microscope slides, and examined in detail. Today, however, evaluation extends far beyond conventional microscopy to include DNA and genetic analysis.<\/p>\n<p>Advanced molecular tests performed on these samples include:<\/p>\n<ul>\n<li>Genetic mutation analysis<\/li>\n<li>Targeted therapy compatibility testing<\/li>\n<li>Immunotherapy biomarker assessment<\/li>\n<li>Next-generation sequencing<\/li>\n<li>Tumor cell typing<\/li>\n<li>Detection of resistance genes<\/li>\n<\/ul>\n<p>These sophisticated analyses reveal not only the type of cancer but also the genetic abnormalities driving tumor growth, the molecular pathways sustaining it, and the mechanisms by which it evades the immune system. Based on this information, physicians can replace traditional chemotherapy with highly targeted oral therapies or immunotherapy designed specifically for the patient&#8217;s tumor profile.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Why_Is_the_Decision_to_Perform_Endobronchial_Ultrasound_EBUS_Vital_in_Thoracic_Surgery\"><\/span>Why Is the Decision to Perform Endobronchial Ultrasound (EBUS) Vital in Thoracic Surgery?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The fundamental principle of medicine is to do no harm. When a mass or enlarged lymph node is detected within the chest, making the correct decision requires clear visualization rather than uncertainty. The most important question in patients diagnosed with lung cancer is whether the disease remains confined to the lung or has spread to the central lymph nodes. If the tumor is localized, timely surgery may be lifesaving. However, if the disease has already spread to deep mediastinal lymph nodes, unnecessary surgery would expose the patient to major physical trauma without providing meaningful benefit.<\/p>\n<p>This advanced diagnostic technology illuminates the hidden regions of the chest, provides information down to the genetic level of the cells, and identifies the treatment from which the patient is most likely to benefit. It influences every aspect of care, from deciding whether surgery is appropriate to selecting the most suitable targeted therapy. It confirms the diagnosis, minimizes unnecessary surgical risk, and opens the door to the most advanced precision medicine available today.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Frequently_Asked_Questions\"><\/span>Frequently Asked Questions<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<div class=\"accordion\">\n\t<div id=\"accordion-3491204098\" class=\"accordion-item\">\n\t\t<a id=\"accordion-3491204098-label\" class=\"accordion-title plain\" href=\"#accordion-item-what-is-endobronchial-ultrasound-(ebus)-and-why-is-it-performed?\" aria-expanded=\"false\" aria-controls=\"accordion-3491204098-content\">\n\t\t\t<button class=\"toggle\" aria-label=\"Toggle\"><i class=\"icon-angle-down\" aria-hidden=\"true\"><\/i><\/button>\n\t\t\t<span>What is endobronchial ultrasound (EBUS) and why is it performed?<\/span>\n\t\t<\/a>\n\t\t<div id=\"accordion-3491204098-content\" class=\"accordion-inner\" aria-labelledby=\"accordion-3491204098-label\">\n\t\t\t\nEndobronchial ultrasound is an advanced diagnostic technique that uses ultrasound to evaluate the bronchi and surrounding lymph nodes.
