Clinical performance of endoscopic ultrasound-guided tissue acquisition for perivascular soft-tissue cuffing suspected to be extravascular migratory metastases of pancreatic or bile duct cancer (with video).

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesThis study aimed to investigate the diagnostic performance and safety of endoscopic ultrasound-guided tissue acquisition (EUS-TA) for perivascular soft-tissue cuffing (PSTC).
methodsThis 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. EUS-TA procedures and outcomes, including technical success, diagnostic performance, adverse events, and comparison with contrast-enhanced computed tomography (CECT), were analyzed.
resultsOf 1803 patients, 53 underwent EUS-TA for PSTC. The sensitivity, specificity, and accuracy were 92.1%, 100%, and 92.5%, respectively. The technical success rate was 98.1% (52/53). The adverse event rate was 1.9%. EUS-TA for PSTC was significantly superior to CECT for PSTC in terms of diagnostic accuracy. Furthermore, the diagnostic performance and adverse event rates for EUS-TA for PSTC were comparable to those for TA in solid tumors. Shorter puncture lengths were associated with lower accuracy.
conclusionEUS-TA for PSTC in pancreatic or bile duct cancer demonstrates high diagnostic accuracy and a low rate of adverse events, showing superior diagnostic performance compared to CECT. These findings suggest that EUS-TA for PSTC can be performed safely and is a clinically beneficial procedure. Despite the technical challenges, EUS-TA for PSTC can influence clinical judgment and should be considered in skilled institutions for future patient treatment decisions. Prospective multicenter studies are warranted to further evaluate its efficacy and safety.
