Efficacy of the U-shaped flap technique in preventing reflux after minimally invasive proximal gastrectomy for proximal gastric and esophagogastric junction cancer.

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: Preventing gastroesophageal reflux after proximal gastrectomy for proximal gastric and esophagogastric junction cancer remains challenging due to the lack of standardized reconstructive techniques. The double flap technique (DFT) in valvuloplastic esophagogastrostomy prevents reflux esophagitis but is less effective in esophagogastric junction cancer because of negative pressure on the inferior mediastinum. We developed the U-shaped flap technique (UFT) to enhance the anti-reflux efficacy. Methods: This study analyzed data from patients who underwent minimally invasive proximal gastrectomy for proximal gastric and esophagogastric junction cancer between August 2014 and May 2022, using a prospectively maintained database. We compared DFT and UFT for short- and long-term outcomes, focusing on gastroesophageal reflux, using one-to-one propensity score matching to control for patient-related variables. Results: Among 217 eligible patients, 205 (100 in DFT, 105 in UFT) completed a 1-year follow-up. After propensity score matching, we selected 42 pairs of patients who underwent DFT and UFT. UFT had significantly shorter operative time ( Conclusion: Our study indicates that the U-shaped flap technique (UFT) offered significant advantages in reducing postoperative reflux symptoms and endoscopic esophagitis, in a cohort of patients with proximal gastric and esophagogastric junction cancer.
