Feasibility and Safety of Robotic Para-Aortic Lymphadenectomy Using the hinotori™ Surgical Robot System: A First-in-Human Experience.
Article in Cureus, 2026. 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
This case series reports the first cases of para-aortic lymphadenectomy performed using the hinotori™ Surgical Robot System (Medicaroid Corporation, Kobe, Japan), Japan's first domestically developed robotic surgical platform. Three patients with gynecologic malignancies (two endometrial and one ovarian cancer) underwent curative surgery, including total hysterectomy, bilateral salpingo-oophorectomy, pelvic lymphadenectomy, and para-aortic lymphadenectomy. All procedures were completed robotically without conversion or intraoperative complications. Operative time ranged from 461 to 512 minutes, and blood loss from 10 to 50 mL. A total of 9-38 para-aortic lymph nodes (median 26) were retrieved, comparable to yields from laparoscopic or da Vinci®-assisted procedures, confirming oncologic adequacy. Postoperative recovery was uneventful in all cases. These cases demonstrate that para-aortic lymphadenectomy using the hinotori™ system is technically feasible and safe. Expanding its use from well-established pelvic surgery to advanced oncologic procedures marks an important milestone for robotic surgery in Japan. Further studies are needed to refine protocols and assess outcomes.
