Guidewire use in electrocautery-enhanced lumen-apposing metal stent procedures: Results of an online survey from an international working group.
Article in Endoscopy international open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background and study aims: This international survey aimed to characterize current practice patterns, perceptions, and outcomes related to guidewire use in electrocautery-enhanced lumen-apposing metal stents (EC-LAMS) procedures. Methods: An online survey of experienced therapeutic endoscopists was conducted, collecting information on preferred techniques, indications for guidewire use, perceived risks, and self-reported adverse events (AEs). Post-hoc analyses explored associations between guidewire use, AEs, and operator experience. Results: Eighty-seven endoscopists (mean age 46.1 years, 88.5% with ≥ 5 years of endoscopic ultrasound (EUS) experience) completed the survey. Freehand deployment was the preferred technique for the majority of all procedures. Guidewire use was mainly preferred for EUS-guided choledochoduodenostomy (EUS-CDS, 24.1%) and EUS-directed transgastric endoscopic retrograde cholangiopancreatography (EDGE, 31%). Reported factors favoring guidewire use included small target lumens and difficult scope positioning. Maldeployment was reported as the most important complication, because 49.3%, and 40.6% of the participants reported at least one maldeployment case in EUS-CDS and EUS-guided gastroenterostomy, respectively. Logistic regression showed that guidewire use in EUS-CDS was perceived to result in higher complication rates (44.1% vs 20.0%; odds ratio 3.16, 95% confidence interval 1.08-9.2, Conclusions: Using an international questionnaire for experienced EUS operators, freehand deployment was identified as the predominant technique for EC-LAMS placement.
