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

introductionRoux-en-Y gastric bypass (RYGB) related late gastro-jejunal (GJ) strictures are often resistant to endoscopic balloon dilations. Lumen-apposing metal stents (LAMSs) have been used to treat benign strictures with favorable results. However, the data remains limited to justify LAMS use for management of post-RYGB late GJ strictures. We aim to evaluate the safety and efficacy of LAMS placement for the management of late GJ strictures that are refractory to balloon dilations in post-RYGB patients.

methodsThis was a single center retrospective study that included all post-RYGB patients who underwent LAMS placement for management of late GJ strictures that had previously failed balloon dilations. Primary outcomes were technical and clinical success, and secondary outcomes were LAMS-related adverse events.

resultsA total of 28 patients underwent LAMS placement for management of GJ strictures. Median age was 60.5 (IQR 50.5, 67.0) years and majority were females (27, 96.4%). Median interval between surgery and first diagnosis of GJ stricture was 13 years (IQR 7, 17.5). 20 × 10 mm LAMS was the most used stent (n = 24, 85.7%). The median procedure time was 23.5 (IQR 14.5, 32.0) minutes. Technical and short-term clinical success of LAMS placement was 100% (95% CI 87.9-100.0). Long-term success was achieved in 19 out of 25 patients (76.0%, 95% CI 56.6-88.5) that had over 3 months follow-up after LAMS removal. Stent migration was noted in 2 (7.1%) patients, and 1 (3.6%) patient each experienced pain and minor bleeding without the need for additional interventions. No patient in our cohort required surgical revision of GJ anastomosis.

conclusionPlacement of LAMS is safe, technically feasible, and associated with a high clinical success rate in patients with late GJ strictures after RYGB who have failed prior balloon dilations. Placement of LAMS can be considered early in patients requiring multiple balloon dilations.
