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

backgroundGastric sleeve stenosis (GSS) is an adverse event following sleeve gastrectomy for which objective tools are needed for diagnosis and treatment. Endoscopic treatment with serial pneumatic balloon dilation may relieve symptoms and prevent the need for conversion to Roux-en-Y gastric bypass. Endoluminal functional impedance planimetry (EndoFLIP) is an endoscopic tool that measures luminal diameter and distensibility indices (DI) and could be used to characterize severity of GSS.

methodsThis was a retrospective analysis of a prospective database of patients referred for symptoms suggestive of GSS. Severity was determined at each endoscopy by a bariatric endoscopist blinded to EndoFLIP measurements. Successive pneumatic balloon dilations were performed until symptoms resolved; failure was defined as referral for conversion. EndoFLIP measurements of stenosis diameter and DI were obtained pre- and post-dilation. Primary outcomes were pre- and post-dilation luminal diameter and DI of GSS. Secondary outcomes were endoscopic severity of GSS, patient characteristics, and need for surgical revision.

results26 patients were included; 23 (85%) were female. Mean age was 45.3 (± 9.9) years. Mean number of dilations was 2.4 (± 1.3) and 10 (38%) patients were referred for conversion. Mild, moderate, and severe GSS was found in 10 (38%), 6 (23%), and 10 (38%) patients, respectively. Moderate and severe GSS underwent more dilations (2.5 ± 1.0 and 3.2 ± 1.6) than mild GSS (1.8 ± 0.8) and were more likely to be referred for conversion. Both pre- and post-dilation diameters were significantly larger in mild versus moderate or severe GSS. Additionally, pre- and post-dilation DI at 30 ml were significantly higher for mild compared to moderate and severe GSS. DISCUSSION: EndoFLIP measurements correlate well with endoscopic assessment of GSS. While more data are needed to determine ideal balloon size and threshold measurements, our results suggest EndoFLIP may help expedite diagnosis and treatment of GSS.
