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

backgroundRoux-en-Y gastric bypass (RYGB) patients can develop anastomotic strictures. The initial management relies on endoscopic hydrostatic balloon dilation, but in a subset of patients, it may be unsuccessful despite several dilations, requiring a different treatment modality. We evaluated the factors associated with balloon dilation failure and need for revision surgery.

methodsRetrospective analysis from patients presenting with a post-RYGB anastomotic stricture who underwent balloon dilation from 2005 to 2018 at Cleveland Clinic Florida and Cleveland Clinic Main Campus. Demographic, clinical, surgical, endoscopic, and post-procedural variables were collected. Univariate and multivariate analysis with odds ratio (OR) and 95% confidence interval (95% CI) calculation for factors associated to dilation failure was performed.

resultsEighty-nine patients were included in the analysis. Population was predominantly white (85.4%) and female (87.6%), with mean age 46.4 years and followed for a mean of 97.4 months. All patients presented dysphagia, with mean stricture diameter of 7.7 mm and associated marginal ulcer in 69%. Successful dilation was achieved in 65 patients, while 24 patients had dilation failure and underwent revisional surgery. Multivariate analysis showed a higher risk of dilation failure if time from RYGB to first dilation was >3 months (OR 4.95, 1.29-19.04; p = 0.02), and if nausea/vomiting were present before first dilation (OR 4.37, 1.11-17.16; p = 0.03). One patient had a perforation after dilation and was treated surgically.

conclusionsPost-RYGB anastomotic strictures can be successfully treated with hydrostatic balloon dilation. However, patients with dilations performed > 3 months after initial RYGB and nausea/vomiting have an increased risk of dilation failure and need for further interventions.
