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

backgroundObesity is a risk factor for the development of a large hiatus hernia. Such hernias are often symptomatic and negatively impact quality of life. However, surgeons can be reluctant to operate on obese patients due to concerns of operative complexity, early hernia recurrence, and increased morbidity. To evaluate this, we assessed the perioperative risks and short-term outcomes following surgery in obese and morbidly obese patients.

methodsPatients who underwent repair of a large hiatus hernia (≥50% intrathoracic stomach) from January 2000 to December 2023 were identified from a prospective database. Patients were categorised based on body mass index (BMI) into 3 groups: non-obese (BMI < 30.0), obese (BMI 30.0-34.9), and morbidly obese (BMI ≥ 35.0). Perioperative and postoperative outcomes were compared.

results915 patients were included (non-obese: 519 [56.7%], obese: 276 [30.1%], morbidly obese: 120 [13.1%]). Morbidly obese patients were younger (69.2 vs 65.8 vs 64 years, p < 0.001) and more likely to be female (60.9 vs 79.7 vs 83.9%, p < 0.001). There were no differences in conversion rates (0.8 vs 0.7 vs 1.7%, p = 0.592), operative time (106.4 vs 103.4 vs 113.6 min, p = 0.074), or length of stay (2.8 vs 2.48 vs 2.57 days, p = 0.063). We found no differences in major complication (4.0 vs 2.9 vs 1.7%, p = 0.435) or return to theatre rates (2.7 vs 1.1 vs 1.7%, p = 0.475). 90-day mortality rates were low for all groups (0.2 vs 0.4 vs 0%). Postoperative heartburn severity was lowest in non-obese patients (0.94 vs 1.86 vs 1.21, p = 0.010). There were no differences in postoperative regurgitation severity (1.02 vs 1.30 vs 1.74, p = 0.185) or overall satisfaction (8.74 vs 8.62 vs 8.91, p = 0.702).

conclusionLarge hiatus hernia repair is safe and effective in obese and morbidly obese populations.
