Non-Flap Tunnel Technique (NFTT): A Novel Minimally Invasive Reconstruction Method After Proximal Gastrectomy for 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
Aim: The incidence of upper-third gastric cancer and esophagogastric junction cancer is increasing, prompting wider adoption of proximal gastrectomy (PG) to preserve postoperative nutritional status and quality of life. Although the double-flap technique (DFT) is effective in preventing reflux after PG, procedural complexity and flap manipulation may contribute to longer reconstruction time and anastomotic stenosis, especially in robotic-assisted procedures. This study aimed to evaluate the non-flap tunnel technique (NFTT) as a simplified alternative to DFT with respect to operative efficiency and anastomotic integrity. Methods: We retrospectively reviewed patients who underwent minimally invasive PG at a single institution between January 2019 and November 2024. Surgical outcomes, including reconstruction time, incidence of anastomotic stenosis, and reflux symptoms, were compared between the DFT and NFTT groups using 2:1 propensity score matching. Results: After matching, 62 patients in the DFT group and 31 patients in the NFTT group were included. NFTT was associated with shorter reconstruction time (87 vs. 108 min; Conclusion: NFTT reduced reconstruction time and anastomotic stenosis while maintaining anti-reflux efficacy. These results support NFTT as a technically feasible and effective alternative to DFT for reconstruction following minimally invasive PG. Prospective studies are warranted to validate long-term outcomes.
