Endoscopic Ultrasound-Guided Pancreatic Tissue Sampling: Lesion Assessment, Needles, and Techniques.
Medicina (Kaunas)
December 2024
Department of Medicine, Diagnostic and Interventional Endoscopy of the Pancreas, The Pancreas Institute, University Hospital of Verona, 37134 Verona, Italy.
Endoscopic ultrasound (EUS)-guided tissue sampling includes the techniques of fine needle aspiration (FNA) and fine needle biopsy (FNB), and both procedures have revolutionized specimen collection from the gastrointestinal tract, especially from remote/inaccessible organs. EUS-FNB has replaced FNA as the procedure of choice for tissue acquisition in solid pancreatic lesions (SPLs) across various society guidelines. FNB specimens provide a larger histological tissue core (preserving tissue architecture) with fewer needle passes, and this is extremely relevant in today's era of precision and personalized molecular medicine.

Pancreatic masses pose a diagnostic difficulty due to the technical complexities related to tissue acquisition. Endoscopic ultrasound (EUS)-guided tissue acquisition has transformed the field by allowing access to pancreatic lesions through fine-needle and biopsy. However, diagnostic accuracy differs based on tumor characteristics and procedural factors.

Department of Gastroenterology, Wuhan Fourth Hospital, Wuhan, China.
Purpose: In solid pancreatic lesions (SPLs), we compared the diagnostic efficacy of a 19G fine-needle aspiration (FNA) needle and a 22G ProCore fine-needle biopsy (FNB) needle, We also compared the specimen quality between the standard suction (SS) technique and heparinized wet-suction (HWS) technique.
Methods: All cases of endoscopic ultrasound-guided tissue acquisition (EUS-TA) by 19G FNA or 22G FNB for SPLs in a single-centre hospital were retrospectively reviewed. The diagnostic yield was compared between the 19G and 22G groups.
Arthroscopic Reconstruction of the Acetabular Labrum Using an Autograft Hip Capsule.

Sports Medicine Center, Department of Orthopaedics, Massachusetts General Hospital, Mass General Brigham, Boston, Massachusetts.
Background: Whereas uncomplicated labral tears with preserved fibers can be effectively treated with use of labral repair techniques, complex tears and hypoplastic labra require labral reconstruction. Standard reconstruction techniques feature grafted tissue that is added to existing, deficient tissue or that is utilized to replace a hypoplastic labrum entirely. However, such approaches utilizing allografts or remote autografts are limited because they often necessitate extensive debridement of the existing labrum to prepare a site for graft implantation, an approach that can damage and devascularize the chondrolabral junction.
