Ultrasound-Guided Percutaneous Core Needle Biopsy for the Diagnosis of Pancreatic Disease

Kao Li, Jingwen Shi, Ying Huang, Yun-Yun Chen
Few studies have evaluated the performance of percutaneous core needle biopsies of the pancreas. This article is an overview of the advantages, disadvantages, predictive power and complications associated with percutaneous ultrasound-guided core needle biopsies of pancreatic lesions. A comprehensive literature search of Medline (using PubMed as the search engine) and EMBASE was done to identify suitable studies up to March 2017. A study of quantitative pre-operative pancreatic biopsy data was reported. Lesion location, mean or median number of passes, inadequate tissue or technical failures and complications were assessed for all cases by reviewing clinical notes and post-procedural imaging. The analysis included 13 studies, mostly of a retrospective nature. The sensitivity (mean: 94.42%, range: 90%–100%) and specificity (mean: 97.94%, range: 94.7%–100%) of the procedure were high, and the mean accuracy of diagnosis was 95.76 (range: 91–100). Furthermore, the procedure had a high negative predictive value of approximately 76.26%. Of the 13 reported studies, 7.3% were inadequate or technical failure cases. The mean rate of complications was 2.08%, which seemed similar to the lower limit of this rate for endoscopic ultrasound-guided fine-needle aspirations. The risk of tumor seeding with ultrasound-guided core needle biopsies was not reported in the included articles. With the development of technology, ultrasound-guided percutaneous core needle biopsy for pancreatic lesions is increasingly available and has optimal diagnostic power in pancreatic neoplasms.
