Predictive Value of Preoperative Ultrasound for Gastric Wall Thickness in Bariatric Procedures.

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 and Objectives: Staple line leakage is a major complication after bariatric surgery, often requiring prolonged and complex treatment. While ultrasonography has been used for gastric cancer screening, its role in evaluating gastric wall before bariatric surgery is not well studied. This study aimed to measure antral gastric wall thickness preoperatively using ultrasonography to provide objective data that may guide stapler selection and reduce complication rates. Methods: Between December 2024 and May 2025, 42 bariatric surgery patients underwent preoperative ultrasonography to measure the total thickness of the gastric antrum's 5 layers. Immediately after surgery, a pressure of 8 g/mm Results: Mean antral, corpus, and fundus wall thicknesses measured by the micrometer under standardized pressure were 2.81 ± 0.36, 2.47 ± 0.27, and 1.71 ± 0.29 mm, respectively. A significant difference was found among these regions ( Conclusion: Preoperative ultrasonography may be sufficient for measuring gastric wall thickness at rest; however, it is inadequate for estimating thickness under intraoperative conditions. Based on our findings and the limited existing literature, conventional ultrasonography does not reliably predict gastric wall thickness under compression. Therefore, noninvasive and cost-effective methods are still needed for accurate preoperative or intraoperative assessment of gastric wall thickness.
