Robotic-assisted proximal gastrectomy with right-sided overlap and single-flap valvuloplasty.

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: The incidence of proximal gastric cancer is increasing. Traditional total gastrectomy compromises nutritional status, while proximal gastrectomy increases the risk of gastroesophageal reflux disease (GERD). To address the reflux issues associated with proximal gastrectomy, robotic-assisted right-sided overlap single-flap valvuloplasty (ROSF) has been developed to overcome the technical challenges of anti-reflux anastomosis. This study evaluates the safety, feasibility, and anti-reflux efficacy of ROSF. Methods: A descriptive case series included 20 patients undergoing robotic-assisted proximal gastrectomy with ROSF for Siewert II/III tumors between April 2023 and April 2024. Outcomes included operative metrics, complications (Clavien-Dindo classification), reflux severity assessed by the GERD scale and Los Angeles classification, and follow-up data. Results: All procedures were completed robotically without conversion. One anastomotic stricture (5.0%) occurred and was resolved with endoscopic dilation. No reflux esophagitis, anastomotic leaks, or postoperative mortality occurred. The mean lymph node yield was 31 ± 6.8, with 14.7 ± 4.3 nodes harvested from the superior margin of the pancreas. GERD scores comparing preoperative (2.4 ± 1.0) and 6-month postoperative (2.7 ± 0.6; Conclusion: Robotic-assisted ROSF is a safe and effective technique for proximal gastrectomy, minimizing reflux and anastomotic complications. Robotic-assisted ROSF is a safe and effective technique for proximal gastrectomy, with favorable short-term outcomes in terms of technical feasibility, anastomotic safety, reflux control, and short-term nutritional stability. Its technical precision in anti-reflux reconstruction and simplified workflow support broader adoption.
