In 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.
在这项研究中，旨在为选择进行胰腺病变活检的方法提供依据。回顾性分析了 2015 年 1 月至 2019 年 11 月期间我院因胰腺肿块接受经皮活检的患者数据。列出了经皮活检方法、操作中使用的针的类型和围手术期并发症。回顾了存档中的病理和细胞学报告，并将活检结果分为 3 组：良性、恶性和不充分。在研究的 308 名患者中，通过评估手术结果、转移性病变活检结果或随访发现，对 124 名患者进行了诊断准确性验证。验证结果分为真阳性和真阴性。在研究的 308 名患者中，23 名患者接受了细针抽吸活检（FNAB），285 名患者接受了核心针活检（CNB）。两组在样本采集成功率和并发症方面无统计学差异。在有明确病理诊断的病变中，恶性病变占 67.74%，良性病变占 32.26%。112 例 CNB 患者中有 107 例（95.54%）和 12 例 FNAB 患者中有 9 例（75.00%）的诊断正确。比较两种方法的成功率发现，CNB 的结果明显更成功。经腹超声引导下经皮 CNB 是一种安全的方法，具有较高的诊断效能，可对胰腺进行活检。
