Robotic esophageal reconstruction with a diagonal stapling technique: technical description and early outcomes from a single-center series.
Article in Surgical endoscopy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundEsophageal reconstruction after total or proximal gastrectomy is technically demanding. Robotic platforms provide enhanced dexterity, yet anastomotic protocols vary widely. We developed a unified, geometry-driven robotic technique-applicable to both total and proximal gastrectomy-that creates a wide V-shaped anastomosis by extending and rotating a right-anterior esophageal flap to maximize perfusion and minimize axial tension.
methodsBetween March 2021 and May 2025, 41 patients underwent robotic gastrectomy using our "diagonal V-geometry" reconstruction: 18 proximal gastrectomies with esophagogastrostomy and 23 total gastrectomies with esophagojejunostomy. A multi-arm surgical robot with 3D visualization and articulating instruments was used. The muscularis was divided directly; the mucosa was incised over a nasogastric tube to avoid contralateral injury. Traction sutures rotated the flap posteriorly, widening the staple line interface. A powered linear stapler created a 40-45-mm V-shaped anastomosis to either the gastric remnant or Roux limb. The enterotomy was closed with a 60-mm staple line. In proximal gastrectomy, a partial Toupet fundoplication was added. Leak tests confirmed integrity. Barbed sutures secured fixation.
resultsMedian age was 73 years (proximal) and 77 years (total); median BMI was 21.6 and 21.2 kg/m
conclusionsOur unified robotic diagonal V-geometry technique yielded zero leaks or strictures in 41 gastrectomies. By rotating the right-anterior flap to create a broad V-shaped staple line, perfusion is preserved and tension minimized. Larger multicenter studies are needed to confirm these promising outcomes.
