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

backgroundThere has been an increase in sleeve gastrectomy (SG) procedures being performed worldwide, and a paralleled rise in prevalence of gastric sleeve stenosis (GSS). Symptoms include dysphagia, reflux, and obstructive symptoms. Upper gastrointestinal series (UGIS) is commonly performed in the diagnostic algorithm prior to referral for endoscopic dilation; however, little is known about its utility in making a diagnosis. Our aim was to evaluate positive predictive value (PPV) and negative predictive value (NPV) of UGIS in detection of GSS.

methodsWe performed a retrospective analysis of a prospectively collected database at a tertiary center for patients referred with nausea/vomiting or obstructive symptoms following SG between 2017 and 2019. All patients underwent upper endoscopy (EGD) for evaluation of GSS. Serial balloon dilations were performed for GSS with increasing balloon size and/or filling pressure until symptom resolution or referral for surgical revision. Primary outcomes were PPV and NPV for UGIS in predicting GSS. Secondary outcomes included EGD findings and symptom response to dilation.

resultsThirty consecutive patients were included in the analyses. The most common presenting symptoms were nausea (66.7%), vomiting (60.0%) reflux (66.7%), and abdominal pain (54.8%). Twenty-two (73.3%) patients underwent UGIS prior to EGD. On diagnostic EGD, 27 (87.1%) patients were diagnosed with GSS. The sensitivity and NPV of UGIS to detect GSS was 30.0%, and 12.5%, respectively. All 6 patients with GSS on UGIS also had GSS on endoscopic evaluation (specificity = 100%, PPV = 100%). Twenty-six (86.6%) patients had resolution of symptoms with a mean 1.97 ± 1.13 dilations.

conclusionUGIS following SG has low NPV to evaluate for GSS. Independent of the UGIS findings, majority of patients found to have GSS on EGD had symptom improvement with dilations. The utility of UGIS is limited for diagnosing GSS and when suspicion for GSS is high, patients should be referred directly for EGD.
