Indwelling biliary stent during Endoscopic Ultrasound-Guided Tissue Acquisition of pancreatic masses: Not necessarily a problem

In this issue of Journal of Clinical Ultrasound: Sonography and other Imaging Techniques, an interesting original research article by Constantinescu et al. addresses the impact of biliary stenting in EUS-TA in patients affected by pancreatic cancer, assessing and comparing the accuracy of sampling pancreatic malignant tissue by means of EUS-TA in patients who underwent prior ERCP with biliary stenting and patients in whom ERCP was not performed. A total of 243 patients with pancreatic cancer who underwent ERCP and EUS-TA, either with Fine-Needle Aspiration (FNA) or Fine-Needle Biopsy (FNB), were retrospectively evaluated.
