Abstract

Aims: We aimed to present the features of our Endobronchial ultrasonography-guided transbronchial needle aspiration (EBUS-TBNA) cases, the lymph nodes that were biopsied, their pathological diagnoses, and the complications that developed due to the procedure.
Methods: All cases who underwent EBUS-TBNA between January 2016 and December 2023 in the chest diseases clinic of a training and research hospital were retrospectively screened. The patients who underwent the procedure (n=274) were included in the study. Cases in which fine needle aspiration biopsy was performed with EBUS-TBNA and the material obtained was not diagnostic (n=3) or in which the pathology result could not be obtained in the files (n=9) were excluded from the study. The design of our study was cross-sectional and planned as a descriptive study.
Results: Of the 262 patients included in the analysis, 66.4% (n=174) were male and the average age of the population was 60.8±11.4 years. When EBUS-TBNA indications were evaluated, the procedure was performed for diagnostic purposes in 96.9% (n=254) and for re-evaluation after chemotherapy in 3.1%. EBUS-TBNA procedure was performed in 16.8% (n=44) patients due to mediastinal mass and in 83.2% (n=218) patients due to mediastinal lymphadenopathy. The most common stations where biopsy is performed with the EBUS-TBNA process are the subcarinal (7) and lower right paratracheal (4R) lymph node stations. When the biopsy results were evaluated, malignancy was reported in 54.6% (n=143) of the patients. The complications related to the EBUS-TBNA procedure were generally mild and trancient .
Conclusion: EBUS-TBNA is a minimally invasive method used in the diagnosis and staging of lung cancer, the evaluation of non-endobronchial lesions, the diagnosis of benign diseases of the mediastinum, and the diagnosis of mediastinal metastases of extrathoracic malignancies. In experienced centers like our clinic, the diagnostic value of the procedure is high and the complication rates are very low.

Endobronşiyal ultrasonografi eşliğinde transbronşiyal iğne aspirasyonu (EBUS-TBNA) uygulanan hastaların genel özellikleri: Tek merkez deneyimi

Abstract

Amaç: EBUS-TBNA olgularımızın tüm özelliklerini ve biyopsi uygulanan lenf nodlarını, patolojik tanılarını ve işleme bağlı gelişen komplikasyonları sunmayı amaçladık
Materyal ve Metod: Bir eğitim ve araştırma hastanesi göğüs hastalıkları kliniğinde Ocak 2016 – Aralık 2023 tarihleri arasında EBUS-TBNA yapılan tüm olgular retrospektif olarak tarandı. İşlem yapılmış 274 olgu çalışmaya dahil edildi. EBUS-TBNA ile ince iğne aspirasyon biyopsi yapılıp alınan materyal tanısal olmayan (n=3) veya kayıtlarda patoloji sonucuna ulaşılamayan (n=9) olgular çalışma dışı bırakıldı. Çalışmamızın dizaynı kesitsel olup tanımlayıcı bir çalışma olarak planlanmıştır.
Results: Analize dahil edilen 262 hastanın %66.4 (n=174) erkekti ve tüm populasyonın yaş ortalaması 60.8±11.4 idi. EBUS-TBNA endikasyonları değerlendirildiğinde %96.9 unda (n=254) işlem tanısal amaçlı %3.1 inde ise işlem kemoterapi sonrası yeniden değerlendirme amacıyla gerçekleştirildi. EBUS-TBNA işlemi %16.8 (n=44) hastada mediastinal kitle nedeniyle, %83.2 (n=218) hastada ise mediastinal lenfadenopati nedeniyle uygulandı. EBUS-TBNA işlemi ile biyopsinin uygulandığı en sık istasyon subkarinal (7) ve sağ alt paratrakeal (4R) lenf nodu istasyonlarıdır. Biyopsi sonuçları değerlendirildiğinde hastaların %54,6 ünde (n=143) malignite raporlandı EBUS-TBNA işlemine bağlı komplikasyonlar genel olarak hafif ve geçici idi.
Conclusion: EBUS-TBNA akciğer kanseri tanı ve evrelemesinde, endobronşiyal olmayan lezyonların tanısında, mediastenin benign hastalıklarının tanısında ve extratorasik malignitelerin mediastinal metastazlarının tanısında kullanılan minimal invaziv yöntemdir. Bizim kliniğimiz gibi deneyimli merkezlerde işlem sonuçlarının tanısal değeri yüksek ve komplikasyon oranları çok düşük olmaktadır.
