1 · What the graph read from 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.

2 · The registry

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

purposeThis study aimed to evaluate the ability of the hinotori™ system to mitigate technical and ergonomic challenges in pediatric laparoscopy by comparing usability, suturing precision, and stress responses with that of conventional laparoscopy in a simulated infant abdomen.

methodsTen pediatric surgeons with limited robotic experience performed peg transfer and suturing in a 1,400-mL box model simulating a 6-month-old abdomen, using robotic-assisted (Robo) and laparoscopic (Lap) approaches in a crossover design. Performance was assessed using the Fundamentals of Laparoscopic Surgery (FLS) score and the A-Lap Mini platform, which evaluates suturing accuracy across five domains. Physiological stress (heart rate and salivary amylase levels) and subjective fatigue (Chalder Fatigue Scale and visual analog scale) were recorded.

resultsPeg-transfer FLS scores were comparable between Robo and Lap (497.5 vs 531), with progressive improvement across Robo trials. Robotic suturing demonstrated greater air-leak resistance, smaller wound openings, and fewer internal collisions. Stress and fatigue indices did not differ significantly, although trends favored Robo.

conclusionPediatric surgeons with minimal robotic experience achieved higher suturing precision using hinotori™, suggesting intuitive usability and potential safety-related benefits in training. Owing to the small sample size, absence of resident-level validation, and lack of formal performance-stress correlation, confirmation in larger cohorts is warranted.
