Tiroid Nodüllerinin İnce İğne Aspirasyon Biyopsisinde İkili Enjektör Modelinin Geleneksel Teknik ile Histopatolojik Sonuçlarının Karşılaştırılması
GİRİŞ ve AMAÇ: Çalışmamızda Ultrasonografi USG kılavuzluğunda geleneksel ince iğne aspirasyon biyopsisi İİAB ve yeni geliştirmiş olduğumuz ikili enjektör modeli ile İİAB işleminin başarı düzeyinin ölçülmesi çalışmamızın amacını oluşturmaktadır.YÖNTEM ve GEREÇLER: Aralık 2017-Mayıs 2018 tarihleri arasında klinisyen istemiyle tarafımıza yönlendirilen tiroid nodülü olan hasta grubunda bilgisayar ortamında tasarladığımız ve 3 boyutlu yazıcıdan çıktısını aldığımız ikili enjektör modeliyle USG klavuzluğunda aynı anda iki iğne ile 130 nodülden Grup 1 ince iğne aspirasyon biyopsisi yaptık. Alınan materyallerin histopatolojik sonuçlarını geleneksel yöntem olan tek iğne kullanılarak yine USG eşliğinde yapılan 169 Grup 2 adet İİAB sonuçları ile istatistiksel olarak karşılaştırdık. Sitolojik tanılar Bethesda sınıflaması baz alınarak yapılmış olup olguların ultrasonografi bulguları belirlenen kriterler dahilinde kaydedilmiştir.BULGULAR: Değerlendirilen olguların malign pozitif /benign negatif oranları, Grup 1 4/99 ile Grup 2 5/133 arasında farklı değildi p= 0,581 . Değerlendirmeye alınan Grup 1 olgularının %14,62 19/130 ’i yanlış, %85.38 111/130 ’u doğru, Grup 2 olgularının 12,43 21/169 ’ü yanlış, %87.57 148/169 ’si doğru, toplam %13,4 40/299 yanlış, %86,6 259/299 ’i doğru bulunmuştur.TARTIŞMA ve SONUÇ: Çalışmamızda ikili enjektör modeli kullanılarak yapılan tirod biyopsisi başarılı bir metod olarak bulunmuştur.
A comparison of the histopathological results of thyroid nodule biopsy applied with ultrasound-guided traditional technique fine needle aspiration and a novel dual-injector model fine needle aspiration
INTRODUCTION: To compare the cytological aspects of traditional ultrasound guided fine needle aspiration biopsy FNAB with the newly developed dual injector model, as the measurement of successMETHODS: A total of 130 thyroid nodules Group 1 were applied with ultrasound-guided fine needle aspiration biopsy with two needles at the same time. This technique was designed in a computer environment and a 3D printed dual injector model was applied to the patient group between December 2017-May 2018. The histopathological results of the obtained materials were statistically compared with the results of 169 Group 2 thyroid nodule FNAB biopsies using a single needle, which is the ultrasound-guided traditional method. Cytological diagnoses were based on the Bethesda classification and ultrasonography findings of the cases were recorded within the specified criteria.RESULTS: No difference was determined in the malignant positive /benign negative ratios of the evaluated cases in Group 1 4/99 and Group 2 5/133 p = 0.581 . In Group 1, the diagnosis was incorrect in 14.62% 19/130 and correct in 85.38% 111/130 of cases. In Group 2, the diagnosis was incorrect in 12.43 21/169 and correct in 87.57% 148/169 of cases. For the whole sample, these rates were 13.4% 40/299 incorrect and 86.6% 259/299 correctly.DISCUSSION AND CONCLUSION: The results of this study showed succesful method in the results of thyroid biopsies made using the binary injector model that was developed in a computer.
