Transthoracic lung and mediastinal biopsies obtained with the Tru-Cut technique: 10 years’ experience

Amaç: Perkütan iğne biyopsileri düşük komplikasyon ve yüksek tanı oranları nedeniyle organ patolojilerinin çoğunda başarıyla uygulanmaktadır. Çalışmamızda coaxial sistem kullanılarak yapılan transtorasik biyopsi sonuçlarını değerlendirmeyi amaçladık.Yöntem ve gereç: Perkütan BT-aracılı coaxial akciğer ve mediastinal biyopsi yapılan 302 hasta (ortalama yaş, 63,1 ± 13,2 yıl) retrospektif olarak incelendi. Lezyon sayısı, çapı, lokalizasyonu, kalsifikasyon içerip içermediği ve akciğer parankiminde amfizem varlığı kaydedildi. İşlem sırasında alınan örnek sayısı, komplikasyon gelişimi ve komplikasyonların tedavisi not edildi. Bulgular: Toraks BT’de lezyon saptanan 270 hastadan işlem sırasında ortalama 5.6 biyopsi alınmıştı. Transtorasik biyopsi yapılan hastalardan 258 (% 95.5)’inin patoloji sonucuna ulaşılabildi ve 226 (% 87,5)’sı tanısal olarak değerlendirildi. Bu çalışmada, 178 (% 68,9) hastanın biyopsi sonucu malignite ile uyumlu idi. Hastalardan 68 (% 25,1)’inde komplikasyon saptandı. Komplikasyon gelişimi ile yaş, cinsiyet, amfizem varlığı ve biyopsi sayısı arasında ilişki saptanmadı. Sonuç: Coaxial sistem kullanılarak alınan transtorasik akciğer ve mediastinal biyopsiler yüksek tanı oranları ve düşük (kabul edilebilir) komplikasyon oranlarına sahiptir.

Tru-Cut tekniği kullanılarak alınan transtorasik akciğer ve mediastinal biyopsiler: 10 yıllık deneyim

Aim: Percutaneous needle biopsy has been used successfully in many organ systems with excellent results and few complications. In this study, we sought to evaluate percutaneous transthoracic biopsy results using a coaxial system. Materials and methods: The records of 302 patients (mean age, 63.1 years) who underwent percutaneous CT-guided coaxial cutting needle lung and mediastinal biopsy were retrospectively evaluated. Number, diameter, location of the lesions, calcification, and emphysema on lung parenchyma were noted. The number of specimens obtained, complications after the procedure, and treatment of complications were recorded.Results: From lesions identified in 270 patients on thoracic CT, a mean of 5.6 biopsy specimens were obtained in 1 procedure. Pathology results of transthoracic biopsies were achieved in 258 patients (95.5%), of whom 226 (87.5%) were diagnostic. At the final diagnosis, 178 biopsy results (68.9%) demonstrated malignancy. Complications were observed in 68 patients (25.1%). No relationship of age, sex, presence of emphysema on lung parenchyma, or the number of biopsy specimens obtained with the development of complications was observed.Conclusion: Transthoracic lung and mediastinal biopsy using a coaxial system is a well tolerated, minimally invasive procedure that has a high diagnosis rate, provides reliable differentiation of malignant and benign lesions, and has an acceptable rate of complications.
