Better outcomes of robotic liver resection in segment VII/VIII compared to open and laparoscopic approach.
Article in Journal of robotic surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundWith the introduction of minimally invasive surgery, laparoscopic and robotic approaches have become increasingly popular for liver resections. However, few studies have compared the perioperative outcomes of open (OLR), laparoscopic (LLR), and robotic liver resections (RLR) together at once for lesions located in the superior parts of the right anterior and posterior segments, S7 and S8. This study reports data for S7 and S8 up to 5 years post-operation.
methodsPerioperative data of S7 and S8 resections performed at Prince of Wales Hospital from January 2014 to December 2024 were retrieved. For statistically significant variables (p < 0.05), pairwise comparisons using Bonferroni correction was performed. Kaplan-Meier method was used for survival analysis.
resultsA total of 162 resections were retrospectively analysed, including 137 open, 14 laparoscopic, and 11 robotic liver resections. Robotic resections achieved the shortest post-operative length of stay (OLR: 7, LLR: 6, RLR: 4 days, p < 0.001) out of the 3 approaches and a 0.0% major complication rate (OLR: 11.7%, LLR: 0.0%, RLR: 0.0%, p = 0.385). Laparoscopic resections had the shortest operative duration (OLR: 175, LLR: 160.5, RLR: 190 min, p < 0.001) and least amount of intra-operative blood loss (OLR: 230, LLR, 60.5, RLR, 100 mL, p = 0.401).
conclusionsDespite an increased operating time, robotic liver resection demonstrated lower rates of major complications and shorter post-operative length of stay compared to open and laparoscopic resections. R1 resection rate and intra-operative blood loss were also comparable to laparoscopic liver resection. This solidifies robotic liver resection as a safe and effacious alternative to its open and laparoscopic counterparts.
