Safety and feasibility of novel single-port robotic systems in colorectal cancer surgery: a comparative study with the da Vinci Xi system.
Article in International journal of colorectal disease, 2025. 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
purposeTo compare perioperative outcomes and safety between the novel single-port robotic systems (SPRS) and the da Vinci Xi robotic system (DVRS) in radical colorectal cancer resection.
methodsIn this retrospective cohort study, 59 patients who underwent curative colorectal resection were assigned to either the SPRS group (n = 21) or the DVRS group (n = 38). Intraoperative metrics, postoperative recovery parameters, and complications were compared between groups.
resultsAll procedures were successfully completed without open conversion and the number of lymph nodes harvested was comparable. The SPRS group demonstrated significantly longer operative times (298.86 ± 76.08 min vs. 227.84 ± 70.20 min; p < 0.001). No significant differences were observed in estimated blood loss, time of gastrointestinal recovery(first flatus), time of dietary resumption (liquid/soft diet), or 30-day readmission rates (p > 0.05). The DVRS group exhibited prolonged median postoperative hospitalization (10.00 days [IQR 8.00-11.75] vs. 8.00 days [IQR 7.00-9.00]; p < 0.05). Patients in the SPRS group reported significantly higher satisfaction scores regarding the cosmetic appearance of postoperative scars compared to those in the DVRS group(7.71 ± 1.01 vs. 6.66 ± 0.91; p < 0.001). Complication rates showed no statistical difference (p > 0.05). All complications were Clavien-Dindo grade I-II managed conservatively, except one SPRS case requiring endoscopic intervention for grade IIIa gastrointestinal hemorrhage.
conclusionsThe novel single-port robotic systems are safe and feasible for radical colorectal cancer surgery. They achieve short-term outcomes comparable to the da Vinci Xi system, with the advantages of a shorter hospitalization and better cosmetic outcomes but at the expense of a longer operative time.
