An initial exploratory clinical study and outcome assessment of gastrointestinal surgeries using advanced robotic-assisted techniques.

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
backgroundIn addition to the Da Vinci surgical robot, domestic surgical robots are being developed rapidly. Chinese Toumai® laparoscopic surgical robot was approved for urological surgery in 2022.This study aims to systematically evaluate the safety and efficacy of the Toumai® robotic surgical system in performing complex gastrointestinal surgeries.
methodsThis prospective, single-center, single-arm exploratory study was conducted at Gansu Provincial Hospital between June 2022 and October 2023, enrolling 12 patients undergoing gastrectomy and 9 patients undergoing colorectal resection. The primary endpoints are oncological outcomes and surgical success rates, while secondary endpoints encompassed intraoperative blood loss, operative duration, complication rates, system performance metrics, length of hospital stay, and postoperative pain levels.
resultsAll patients successfully underwent robotic-assisted surgery with adequate oncological resection and favorable postoperative outcomes. There were no conversions to open or laparoscopic surgery, resulting in a 100% procedural success rate. The median docking time for radical gastrectomy was 17.50 (14.25, 21.50) minutes, with a median master-slave control time of 121.50 (105.50, 172.00) minutes, median intraoperative blood loss of 100.00 (50.00, 275.00) mL, and a median postoperative hospital stay of 9.00 (7.25, 10.75) days. For radical colorectal surgery, the median docking time was 22 (17.50, 30.50) minutes, the median master-slave control time was 68 (56.50, 119.00) minutes, with a median blood loss of 50 (50.00, 150.00) mL, and a median postoperative hospital stay of 7 (7.00, 10.00) days. No intraoperative organ injury, mortality, system failure, or severe postoperative complications were reported.
conclusionsThese preliminary findings provide compelling evidence supporting the safety and efficacy of the Toumai® laparoscopic surgical robotic system in performing gastric and colorectal surgeries.
