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

backgroundSleeve gastrectomy (SG) is the most commonly performed weight loss operation, and its 2 most common complications are postoperative reflux and weight recurrence. There is limited evidence to guide decision-making in treating these conditions.

objectivesTo determine the efficacy of conversion of SG to Roux-en-Y gastric bypass (RYGB) for GERD management and weight loss.

settingForty-one hospitals in Michigan.

methodsWe conducted a retrospective cohort study examining patients who underwent conversion of SG to RYGB from 2014 to 2022. The primary outcomes were changes in GERD-HRQL scores, anti-reflux medication use, and weight from baseline to 1 year after conversion. Secondary outcomes included 30-day postoperative complications and resource utilization.

resultsAmong 2133 patients undergoing conversion, 279 (13%) patients had baseline and 1-year GERD-HRQL survey data and anti-reflux medication data. GERD-HRQL scores decreased significantly from 24.6 to 6.6 (P < .01). Among these, 207 patients (74%) required anti-reflux medication at baseline, with only 76 patients (27%) requiring anti-reflux medication at 1 year postoperatively (P < .01). Of the 380 patients (18%) with weight loss data, mean weight decreased by 68.4lbs, with a 24.3% decline in total body weight and 51.5% decline in excess body weight. In terms of 30-day complications, 308 (14%) patients experienced any complication and 89 (4%) experienced a serious complication, but there were no leaks, perforations, or deaths. Three-hundred and fifty-five (17%) patients presented to the emergency department and 64 (3%) patients underwent reoperation.

conclusionsThis study represents the largest reported experience with conversion from SG to RYGB. We found that conversion to RYGB is associated with significant improvement in GERD symptoms, reduction in anti-reflux medication use, and significant weight loss and is therefore an effective treatment for GERD and weight regain after SG. However, the risks and benefits of conversion surgery should be carefully considered, especially in patients with significant comorbidity burden.
