A prospective, head-to-head comparison of 2 EUS-guided liver biopsy needles in vivo.

Background And Aims: Procedural standardization in endoscopic ultrasound-guided liver biopsy (EUS-LB) is necessary to obtain core biopsy specimens for accurate diagnosis. The objective of this study was to directly compare the diagnostic yield of 2 EUS-LB fine-needle biopsy (FNB) systems in vivo.

Methods: In this prospective, single-center study, 108 adult patients undergoing EUS-LB over a 1-year period were included.

Upper Gastrointestinal Crohn's Disease: Literature Review and Case Presentation.

Upper gastrointestinal tract predominant Crohn's Disease (CD) remains an elusive clinical entity, manifesting limited or vague symptomatology, eluding clinical suspicion, and delaying subsequent diagnostic evaluation. As a result, it has not been widely described and there is a lack of clear recommendations for diagnosis or management. Standard IBD evaluation including serologic testing, imaging, and endoscopy may initially not be fruitful.
