Clinical application and observation of 5G remote robotic radical gastrectomy for gastric cancer.
Article in Surgical endoscopy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
objectiveTo evaluate the safety and short-term efficacy of 5G remote robotic surgery in radical gastrectomy for gastric cancer, with a focus on technical feasibility and perioperative outcomes.
methodsA retrospective analysis was conducted on ten cases of 5G remote robotic radical gastrectomy for gastric cancer performed between May 2023 and November 2024 at Gansu Provincial Hospital in collaboration with the Affiliated Hospital of Yangzhou University and the New District Branch of Gansu Provincial Hospital. Primary endpoints included intraoperative network latency, operative duration, estimated blood loss, D2 lymphadenectomy adequacy, Clavien-Dindo complication grade, and R0 resection rate, and other indicators.
resultsNetwork Parameters: For procedures with a communication distance of 1758 km (n = 5), the median (interquartile range, IQR) network latency was 91 (70-100) ms; for those with a distance of 63 km (n = 5), the median (IQR) latency was 51 (46-71.5) ms. No obvious abnormalities in the network connection. Surgical outcomes: Total gastrectomy (n = 3) had a median of 285 min (IQR 265-320), while distal gastrectomy (n = 7) had a median of 230 min (IQR 200-260). Estimated intraoperative blood loss 35 ± 13.44 mL. One patient required 3 units RBC transfusion for preoperative anemia. Conversion to open surgery rate was 0%. COMPLICATIONS: All postoperative complications were ≤ Clavien-Dindo Grade II, with no severe adverse events. Pathological Results: The number of dissected lymph nodes was 32.8 ± 7.08, the number of positive lymph nodes was 2.9 ± 3.81, and the R0 resection rate was 100%.
conclusionThis study preliminarily confirms that 5G remote robotic radical gastrectomy is technically feasible and has good short-term safety. Despite the limitation of a small sample size, its results provide a reference for conducting pilot studies on remote surgery. In the future, larger-scale, long-term follow-up-controlled studies will be needed to further verify its clinical value and cost-effectiveness.
