Objectives: This study aimed to investigate the diagnostic performance and safety of endoscopic ultrasound-guided tissue acquisition (EUS-TA) for perivascular soft-tissue cuffing (PSTC).
Methods: This single-center, retrospective study evaluated patients in whom EUS-TA was performed for PSTC in pancreatic or bile duct cancer lesions between October 2017 and March 2024. PSTC was defined as a perivascular soft-tissue area contiguous with nearby blood vessels from the suspected primary tumor.

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, Aichi Cancer Center Hospital, Nagoya, Japan.
Background/aims: Biliary obstruction drainage in patients with hepatocellular carcinoma (HCC) is associated with symptom palliation, improved access to chemotherapy, and improved survival. Stent placement and exchange via endoscopic retrograde cholangiopancreatography biliary drainage risk traversing the HCC, a hypervascular tumor and causing bleeding. Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) potentially prevents procedure-related bleeding.

Department of Internal Medicine, College of Medicine, National Taiwan University, Taipei, Taiwan.
Background/aims: Endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) is an essential tool for tissue acquisition in solid pancreatic tumors. Rapid on-site evaluation (ROSE) by cytologists ensures diagnostic accuracy. However, the universal application of the ROSE is limited by its availability.

This condition is typically associated with ipsilateral renal agenesis and is known as Herlyn-Werner-Wunderlich syndrome or OHVIRA (Obstructed HemiVagina and Ipsilateral Renal Anomaly) syndrome. The primary symptoms include dysmenorrhea and pelvic pain, which usually manifest after menarche due to haematocolpos in the obstructed hemivagina.
