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

backgroundTelesurgery is gaining traction across surgical specialties. However, its use in radical gastrectomy for gastric cancer remains limited. This study evaluated the safety and feasibility of fifth-generation (5G) robot-assisted remote radical gastrectomy using the Toumai Endoscopic Surgery Robotic System.

methodsIn this prospective single-center single-arm clinical study, eligible patients underwent 5G remote radical gastrectomy over a distance of 15 km. The primary outcome was the incidence of intraoperative and postoperative complications. Secondary outcomes included surgical completion rate, operative duration, estimated blood loss, number of lymph nodes dissected, time to first flatus and diet, and hospital stay.

resultsTwenty-seven patients were enrolled between September and December 2023. All surgeries were completed successfully, with no conversion and a 100% R0 resection rate. No intraoperative complications occurred. Postoperative complications occurred in 18.5% of patients, with no Clavien-Dindo grade ≥ III. The mean operative time was 192.6 ± 34.8 min, and mean blood loss was 35.9 ± 15.9 mL. Lymph nodes were dissected at an average of 38.4 ± 13.2 lymph nodes. Median time to first flatus and oral intake was 2.0 days, to liquid diet was 4.0 days, and hospital stay was 7.0 days. The 5G network was highly stable, with total delay of 226.2 ± 4.4 ms, round-trip delay of 31.6 ± 3.8 ms, and packet loss < 0.1%.

conclusionsThe 5G robot-assisted remote radical gastrectomy using the Toumai system is safe and feasible for selected patients with gastric cancer. The integration of 5G and robotics may offer a promising telemedicine approach to surgical oncology.
