“…Percutaneous biopsy is a widely used interventional procedure for tissue sampling. Imaging methods are a safe tool in access of the needle to the target (13,14,15). The first preferred method is USG-guided liver biopsy because of its advantages such as evaluation of the parenchyma, imaging of the gallbladder, ability to distinguish intrahepatic main vascular structures with Doppler, not exposing patients to radiation, and being inexpensive, easy to use and portable.…”

“…The first preferred method is USG-guided liver biopsy because of its advantages such as evaluation of the parenchyma, imaging of the gallbladder, ability to distinguish intrahepatic main vascular structures with Doppler, not exposing patients to radiation, and being inexpensive, easy to use and portable. In addition, real time imaging is another advantage of USG-guided biopsy (15,16). Percutaneous biopsies using imaging methods have largely prevented complications of blind biopsy and unnecessary operations (10,13).…”

Objectives: To investigate the effect of the biopsy technique used in percutaneous liver biopsies applied with semi-automatic 16 gauge (G) and 18G Tru-cut and Menghini aspiration needles in patients with chronic hepatitis B (CHB) on pathological evaluation. Materials and Methods: The study included 104 cases diagnosed with CHB who underwent liver biopsy between 2013 and 2018. The pathology results of biopsies were evaluated with the Menghini technique under ultrasound (USG) guidance (n=26), and with 16G (n=54) and 18G (n=24) semi-automatic Tru-cut needles under USG. Results: The fibrosis score in 5 (9.3%) of the 16G cases and in 3 (12.5%) of the 18G cases, and the ISHAK score in 3 (5.6%) of the 16G and in 1 (4.2%) of the 18G cases could not be determined. There was no significant difference between the methods and needle types in terms of the number of pieces, number of portal sites, fibrosis and ISHAK score (p>0.05). There was a statistically significant difference between the biopsies performed with Menghini method and Tru-cut method with 16G and 18G (p<0.0001) in terms of material length. The diagnosis rates for the Menghini technique, and 16G and 18G Tru-cut needles were 100%, 90.7% and 83.3%, respectively, with no statistically significant difference determined (p>0.05). Conclusion: Although a larger tissue piece is obtained with the Menghini technique, allowing evaluation of a larger portal area, no significant difference was determined between the techniques in the pathological evaluation. Taking patient safety and comfort into consideration, Tru-cut needle biopsy under USG guidance is recommended rather than the Menghini technique as less trauma is created.

AimTo examine the intra‐ and inter‐observer variability for non‐benign thyroid cytological subcategories according to the Bethesda classification system after the second review.MethodsBetween November 2018 and May 2019, thyroid fine needle aspiration biopsies of 381 nodules were retrospectively evaluated. Among them, 74 non‐benign (category III‐VI) thyroid biopsies, analyzed according to the Bethesda system (pathologist 1:40 vs pathologist 2:34) by two independent pathologists, were reassessed by the same pathologists and by a cytopathologist. In this observer‐blinded study, weighted Cohen's kappa was used to assess the intra‐observer agreement, and Krippendorff's alpha was used to assess the inter‐observer agreement.ResultsAt the first and second evaluations of pathologists 1 and 2, the percentage agreement was 62.5% for pathologist 1 and 58.8% for pathologist 2. The intra‐observer agreement was substantial (κ = 0.705) for pathologist 1, and moderate (κ = 0.447) for pathologist 2. In the second evaluation of pathologist 1 and 2, which was compared with the cytopathologist, the agreement percentage of pathologist 1 with the cytopathologist was 50.0%, and that of pathologist 2 was 56.8%. The inter‐observer agreement was below the lowest acceptable limit for an overall agreement (α = 0.634) among the three raters. The inter‐observer agreement was only acceptable between the cytopathologist and the second pathologist, while it was low between the other raters. In the evaluation of the non‐benign nodules, the mean category score of the cytopathologist was 3.22 and lower than both pathologists (3.73 and 3.58, respectively).ConclusionsThe intra‐observer agreement of pathologists was moderate‐to‐substantial in the evaluation of non‐benign thyroid biopsies according to the Bethesda reporting system. However, the inter‐observer agreement was below the lowest acceptable limit when the cytopathologist was taken as a reference.
