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

backgroundPatients who undergo vertical sleeve gastrectomy (VSG) are at risk of postoperative GERD. The reasons are multifactorial, but half of conversions to Roux-en Y gastric bypass are for intractable GERD. Our institution routinely performs preoperative pH and high-resolution manometry studies to aid in operative decision making. We hypothesize that abnormal pH studies in concert with ineffective esophageal motility would lead to higher rates of postoperative reflux after VSG.

methodsA single institution retrospective review was conducted of adult patients who underwent preoperative pH and manometry testing and VSG between 2015 and 2021. Patients filled out a symptom questionnaire at the time of testing. Postoperative reflux was defined by patient-reported symptoms at 1-year follow-up. Univariate logistic regression was used to examine the relationship between esophageal tests and postoperative reflux. The Lui method was used to determine the cutpoint for pH and manometric variables maximizing sensitivity and specificity for postoperative reflux.

resultsOf 291 patients who underwent VSG, 66 (22.7%) had a named motility disorder and 67 (23%) had an abnormal DeMeester score. Preoperatively, reflux was reported by 122 patients (41.9%), of those, 69 (56.6%) had resolution. Preoperative pH and manometric abnormalities, and BMI reduction did not predict postoperative reflux status (p = ns). In a subgroup analysis of patients with an abnormal preoperative pH study, the Lui cutpoint to predict postoperative reflux was a DeMeester greater than 24.8. Postoperative reflux symptoms rates above and below this point were 41.9% versus 17.1%, respectively (p = 0.03).

conclusionWhile manometry abnormalities did not predict postoperative reflux symptoms, GERD burden did. Patients with a mildly elevated DeMeester score had a low risk of postoperative reflux compared to patients with a more abnormal DeMeester score. A preoperative pH study may help guide operative decision-making and lead to better counseling of patients of their risk for reflux after VSG.
