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

backgroundGas bloat syndrome (GBS) is a recognized complication of Nissen fundoplication (NF), characterized by impaired gastric venting and progressive distention. Although its negative impact on quality of life is well established, the relationship between GBS, anatomical failure, and revisional surgery remains unclear. This study evaluated the association between GBS, clinical outcomes, anatomical integrity, and reoperation after NF. STUDY

designWe analyzed 554 patients who underwent primary NF at our institution and completed postoperative GERD-Health-Related Quality of Life (GERD-HRQL) questionnaires. GBS was defined as a gas bloat symptom score greater than or equal to 4 at 1 year. Anatomical failure was defined by endoscopic evidence of recurrent hiatal hernia or fundoplication disruption. GBS was classified as new-onset or persistent based on preoperative symptoms. Clinical outcomes, including GERD-HRQL, patient satisfaction, proton pump inhibitor use, pH normalization, and revisional surgery, were compared between patients with and without GBS.

resultsAt 1 year, 24.7% of patients met criteria for GBS. Compared with patients without GBS, those with GBS had higher GERD-HRQL scores, lower satisfaction, and greater proton pump inhibitor use (all p < 0.01). By postoperative year 5, anatomical failure occurred more frequently in patients with GBS (46.7% vs 15.3%, p < 0.0001) and occurred earlier (median 22 vs 32 months, p = 0.0012). Revisional surgery was more common in the GBS group (28.5% vs 8.5%, p < 0.001). Outcomes were similarly poor in patients with new-onset and persistent GBS. Delayed gastric emptying did not predict symptom severity or clinical outcomes.

conclusionsGBS is associated with worse postoperative quality of life, higher rates of anatomical failure, and increased revisional surgery after NF. Routine identification and longitudinal monitoring of GBS may help guide postoperative management and improve long-term outcomes.
