Öğe Diagnostic Yield of Transabdominal Ultrasound-Guided Core Needle Method in Biopsies of Pancreatic Lesions(Lippincott Williams & Wilkins, 2023) Turgut, Bekir; Bakdik, Sueleyman; oencue, Fatih; Kuecuekosmanoglu, Ilknur; Eren Karanis, Meryem Ilkay; Kerimoglu, Ramazan Saygin; Saracoglu, MustafaIn this study, it was aimed to contribute to the selection of the method to perform pancreatic lesion biopsies.Data of patients, who had undergone a percutaneous biopsy because of pancreatic masses in our institution in the period between January 2015 and November 2019, were evaluated retrospectively. The percutaneous biopsy method, the type of needle used in the procedure, and periprocedural complications were listed. Pathology and cytology reports in the archive were reviewed, and biopsy results were divided into 3 groups as benign, malignant, and inadequate. Of 308 patients included in the study, the diagnostic accuracy was verified in 124 patients through the assessment of surgical outcomes, results of biopsies from metastatic lesions, or follow-up findings. The verified results were classified as true-positives and true-negatives.Of a total of 308 patients included in the study, 23 underwent a fine-needle aspiration biopsy (FNAB) and 285 underwent a core needle biopsy (CNB). No statistical differences were observed in sample acquisition success and complications between the groups.Of the lesions with a confirmed pathological diagnosis, 67.74% were malignant and 32.26% were benign. The diagnosis was correct in 107 of 112 CNB patients (95.54%) and 9 of 12 FNAB patients (75.00%). When the success of the 2 methods was compared, it was found that outcomes of CNB were statistically more successful compared with those of FNAB.A transabdominal ultrasound-guided percutaneous CNB is a safe method with a high diagnostic yield to perform a biopsy of the pancreas.Öğe Two-Dimensional Shear Wave Elastography in the Assessment of Salivary Gland Involvement in Primary Sjogren's Syndrome(Wiley, 2020) Arslan, Serdar; Durmaz, Mehmet Sedat; Erdogan, Hasan; Esmen, Serpil Ergulu; Turgut, Bekir; Iyisoy, Mehmet SinanObjectives The aim of this study was to investigate the diagnostic performance of two-dimensional (2D) shear wave elastography (SWE) in the assessment of salivary gland involvement in primary Sjogren's syndrome (pSS). Methods Fifty-three patients with pSS and 30 healthy volunteers were included. The echogenicity of all submandibular and parotid glands was evaluated with B-mode ultrasound, and their elasticity was assessed with 2D SWE. The mean and standard deviation of the shear wave speed and elasticity modes on 2D SWE were calculated. Results The mean shear wave speed and elasticity mode values for the submandibular and parotid glands were significantly higher in the patients with pSS (P < .05). The mean elasticity of the shear wave speed mode was best able to differentiate the parotid glands of patients with pSS from those of healthy volunteers at a cutoff value of 2.48 m/s, whereas the mean elasticity of the elasticity mode was best able to differentiate the submandibular glands of patients with pSS from those of healthy volunteers at a cutoff value of 21 kPa. Conclusions Two-dimensional SWE is an effective technique for assessment of the parenchyma of the salivary glands in patients with pSS and predicts interstitial fibrosis and the severity of histologic damage.
