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. Each EUS-LB consisted of an EGD, followed by EUS-guided biopsy of the left lobe of the liver sequentially using 2 different 19-gauge needles: the fork-tip (SharkCore) and Franseen (Acquire) FNB systems. Specimens were then reviewed by a GI histopathologist to determine diagnostic adequacy as well as the number of complete portal tracts, specimen length, and degree of fragmentation.

Results: In 79.4% of cases, the fork-tip FNB system yielded a final diagnosis compared with 97.2% of the Franseen FNB specimens (P < .001). The mean number of complete portal tracts in the fork-tip FNB samples was 7.07 compared with 9.59 in the Franseen FNB samples (P < .001). The mean specimen length was 13.86 mm for the fork-tip FNB and 15.81 mm for the Franseen FNB (P = .004). Cores were intact in 47.6% of the fork-tip FNB samples and in 75.2% of the Franseen FNB samples (P = .004).

Conclusions: In EUS-LB, we found that the 19-gauge Franseen FNB system resulted in a statistically significant increase in diagnostic adequacy compared with biopsy using the fork-tip FNB system.

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

Case Rep Gastrointest Med 2019 20;2019:2708909. Epub 2019 May 20.

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. Furthermore, endoscopic evaluation may be grossly normal in patients without long standing-disease. We describe an 18-year-old male who presented with only unexplained, persistent iron-deficiency anemia. Extensive outpatient testing including multiple endoscopic evaluations with standard biopsies was unfruitful. Ultimately, a positive fecal calprotectin prompted enteroscopy with endoscopic mucosal resection (EMR) in an effort to obtain a larger, deeper tissue specimen. Grossly cobblestoned mucosa along with histopathology revealing focal crypt abscesses, chronic inflammation in the lamina propria, and superficial foveolar epithelial regenerative changes were consistent with CD. This patient's case illustrates the need for a high degree of suspicion for CD in patients with unexplained or persistent iron deficiency anemias. Persistent investigation yielded an elevation in fecal calprotectin suggesting underlying gastrointestinal inflammation and prompted advanced endoscopic evaluation with EMR. Waxing and waning tissue findings are characteristic of CD and pose a unique challenge in patients with upper gastrointestinal predominant pathology. As such, diligent workup including laboratory evaluation, imaging, and serial endoscopy is critical to establish pathology and dictate subsequent management in IBD, especially upper gastrointestinal tract predominant CD.
