Diagnosis of Sliding Hiatal Hernia in Patients With Morbid Obesity: A Comparison of High-resolution Esophageal Manometry and Upper Gastrointestinal Series.

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.
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
Background/Aims: Evidence regarding the diagnostic value of non-to-minimally invasive investigations for identifying sliding hiatal hernia (HH) in patients with morbid obesity is limited. Herein, we aimed to evaluate the diagnostic performance of preoperative high-resolution esophageal manometry (HREM) compared with that of upper gastrointestinal (UGI) series in this patient population. Methods: In this retrospective comparative-paired design study at a university hospital, we analyzed data from 149 consecutive patients with morbid obesity who underwent bariatric surgery (BS) between 2020 and 2024. All patients underwent preoperative workup, including HREM, UGI series, and esophagogastroduodenoscopy. Diagnostic performance was evaluated and compared between the diagnostic tests using intraoperative HH diagnosis as a reference standard. Results: After excluding 12 patients, BS confirmed sliding HHs in 26 of 137 patients (19.0%). HREM showed a superior predictive capacity for identifying intraoperative HH than UGI series, showing area under the receiver operating characteristic curves of 0.93 (95% confidence interval [CI], 0.87-0.99; Conclusion: HREM has high diagnostic performance in detecting sliding HH; thus, HREM should be considered as an important part of the preoperative work-up for patients with morbid obesity.
