Comparing Needles and Methods of Endoscopic Ultrasound–Guided Fine-Needle Biopsy to Optimize Specimen Quality and Diagnostic Accuracy for Patients With Pancreatic Masses in a Randomized Trial

Background & Aims Given the lack of procedure standardization, findings vary from analyses of pancreatic tissues collected by endoscopic ultrasound–guided fine-needle biopsy. It is not clear which needle and technique yield the best specimen for analysis. We compared the specimen quality and accuracy of diagnoses made from samples collected by fine-needle biopsy needles using different collection techniques. Methods Patients found to have...
