1 · What the graph read from it

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.

2 · The registry

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

backgroundGastrojejunal (GJ) anastomotic strictures are a challenging complication following Roux-en-Y gastric bypass (RYGB) and may be refractory to conventional balloon dilation. Lumen-apposing metal stents (LAMS) provide anchored, wide-caliber support that may treat strictures, yet long-term outcomes remain variable, and stent migration is a concern. This study evaluates the clinical effectiveness and safety of LAMS with or without concurrent endoscopic stricturoplasty in patients with GJ strictures.

methodsWe conducted a single-center retrospective cohort study of patients with GJ strictures who underwent LAMS placement between January 2020 and May 2025. Patients were stratified by whether concurrent endoscopic stricturoplasty was performed at the time of stent placement. Clinical success was defined as symptom resolution without need for reintervention. The primary outcome was long-term clinical success (> 90 days). Secondary outcomes included short-term clinical success (≤ 30 days), stent dwell time, procedure duration, stent migration, and adverse events.

resultsTwenty-five patients were included (mean age 46.8 ± 12.9 years; 76% female), with 7 (28%) undergoing concurrent stricturoplasty. The overall cohort short-term and long-term clinical success rates were 88.0% and 64.0% respectively. Long-term success was 71.4% in the stricturoplasty group vs. 61.1% in the LAMS-only group (p = 0.985). Stent migration occurred in 3 patients (12.0%), all in the LAMS-only group (0% vs. 16.7%, p = 0.641). Mean stent dwell time was shorter in the stricturoplasty group (52.6 vs. 90.4 days, p = 0.896), and the stricturoplasty group had significantly higher rates of prior ≥ 3 balloon dilations (85.7% vs. 16.7%, p = 0.006), suggesting a more refractory phenotype.

conclusionsLAMS is a safe and effective treatment for GJ strictures after RYGB, with high short-term success. In patients with multiple prior dilations or complex fibrotic strictures, concurrent stricturoplasty appears to be a technically feasible adjunct that may reduce stent migration and improve durability. These trends support further investigation.
