Fusion surgery in robot-assisted esophagectomy: stepwise learning curves across the da Vinci™ and hinotori™ platforms.
Article in World journal of surgical oncology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled it.
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
backgroundRobot-assisted minimally invasive esophagectomy (RAMIE) provides superior precision, three-dimensional visualization, and enhanced instrument dexterity compared to conventional approaches. The “Fusion Surgery” concept, which emphasizes dynamic cooperation between console and bedside surgeons, has the potential to improve operative efficiency and facilitate technical skill acquisition. This study used stepwise learning curves in RAMIE to explore the feasibility and initial experience with the da Vinci™ and hinotori™ robotic platforms.
methodsWe retrospectively analyzed 30 patients with esophageal cancer who underwent RAMIE using the Fusion Surgery approach between June 2024 and November 2025. The first 25 consecutive procedures were performed with the da Vinci system, followed by five with the hinotori system, all by the same surgical team. Thoracic lymphadenectomy was standardized into lower, middle, and upper mediastinal segments. Learning curves were assessed using cumulative sum (CUSUM) analysis of console operation time. Intraoperative blood loss and postoperative hospital stay were evaluated as secondary outcomes.
resultsThe median total console operation time was 210 min. Middle mediastinal dissection time was significantly shorter with the hinotori system than with the da Vinci system (46 vs. 76 min, p = 0.010), whereas upper and lower mediastinal dissections showed favorable trends. CUSUM analysis demonstrated progressive improvement across all mediastinal levels. Upper mediastinal console time continued to decrease after transition to the hinotori system, middle mediastinal dissection showed marked improvement following the transition, and lower mediastinal dissection exhibited a steady downward trend from the initial cases. These findings indicate cumulative learning and effective transfer of technical skills across robotic platforms.
conclusionsThe Fusion Surgery approach may support gradual improvement in RAMIE performance across all mediastinal levels. Transitioning from the da Vinci to the hinotori robotic system did not interrupt the learning curve, supporting smooth continuation of surgical proficiency on a new platform. Fusion Surgery may provide a robust and adaptable framework for sustained technical advancement in RAMIE.
