Dry suction versus wet suction of endoscopic ultrasound-guided fine-needle biopsy for diagnosis of solid pancreatic lesions:a multicenter randomized controlled non-inferiority trial.

Background And Aims: Conclusions regarding the suction techniques of EUS-FNB remain controversial. This study aimed to compare the diagnostic accuracy of the dry suction versus wet suction technique in solid pancreatic lesions (SPLs) and determine the optimal number of passes for EUS-FNB.

Methods: This investigation was conducted as a multicenter, randomized, controlled, non-inferiority trial.

Linear-Array Endoscopic Ultrasound and Narrow-Band Imaging Measure the Invasion Depth of Nonpedunculated Rectal Lesions With Comparable Accuracy Based on a Randomized Controlled Trial.

Introduction: Linear-array endoscopic ultrasound (EUS) and narrow-band imaging (NBI) are both used to estimate the invasion depth of nonpedunculated rectal lesions (NPRLs). However, it is unclear which procedure is more accurate. This randomized controlled trial aimed to compare the diagnostic accuracy of linear EUS and NBI for estimating the invasion depth of NPRLs.
