Lumen Apposing Metal Stents for Gastrojejunal Anastomotic Stricture Following Metabolic Bariatric Surgery.
Article in Obesity surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundThe standard of care for gastrojejunal anastomotic stricture following metabolic bariatric bypass surgery is endoscopic balloon dilatation, with revisional surgery as a last line option. The use of lumen-apposing metal stents is expanding to include many gastrointestinal benign and malignant causes in selected cases. They may provide an additional treatment option for post-bypass strictures.
methodsA single centre, retrospective outcomes analysis was performed over a 3-year period of patients with gastrojejunal anastomotic stricture following metabolic bariatric surgery that was treated with a lumen-apposing metal stent. Primary outcomes assessed were clinical success and perforation. Multiple secondary outcomes were assessed regarding safety and endoscopy use.
resultsOf 88 patients that had lumen-apposing metal stents placed, 20 satisfied selection criteria. Eleven patients (55%) had at least one balloon dilatation prior to stent placement. All patients achieved clinical success 20 (100%) with zero perforations. Technical success was achieved in 19 patients (95%). There were four (20%) recurrent strictures, two stent migrations (10%) (with no associated complication), and one in-stent food bolus obstruction (5%). One patient ultimately required surgical revision (5%). Three patients had endoscopy within 30 days of stent removal (15%), and five patients required unplanned endoscopy with the stent in situ (25%).
conclusionLumen-apposing metal stents within our study show potential as another treatment option for gastrojejunal anastomotic stricture following gastric bypass.
