Comparison of surgical results and technical performance between robotic and laparoscopic approaches for Kasai portoenterostomy in biliary atresia: a multicenter retrospective study.
Article in Surgical endoscopy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled 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.
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
backgroundMany variables, including age at surgery, disease type, surgical approaches and perioperative management factors have been demonstrated to influence efficacy in BA infants, however, the effect of surgical performance remains unclear. The objective of this retrospective study was to compare the postoperative efficacy and surgical performance of robotic (RKPE) versus laparoscopic Kasai portoenterostomy (LKPE) for BA.
methodsBetween October 2018 and June 2023, 158 type III BA patients undergoing minimally invasive surgery (RKPE = 66, LKPE = 92) were included in this multicenter retrospective study. All procedures were performed by surgical teams experienced in Kasai portoenterostomy techniques. Technical performance was quantified and analyzed using the Objective Structured Assessments of Technical Skills (OSATS) and Generic Error Rating Tool instruments (GERT). Postoperative outcomes and surgical performance were compared.
resultsCompared with LKPE group, RKPE group had shorter fibrous cone transection time (48.92 ± 6.98 vs. 61.45 ± 8.98 min; p < 0.001), shorter hepaticojejunostomy time (47.55 ± 6.57 vs. 59.93 ± 7.88 min; p < 0.001) and less estimated intraoperative bleeding [7.00 (5.00-10.00) vs. 13.50 (10.50-16.50) mL; p < 0.001]. More importantly, RKPE group showed a superior OSATS score [30.50 (29.00-31.00) vs. 28.00 (28.00-29.00); p < 0.001], number of errors (46.62 ± 6.32 vs. 56.40 ± 6.82 times/case; p < 0.001), and number of events [9.40 (8.40-10.40) vs. 16.00 (14.00-17.80) times/case; p < 0.001]. On postoperative days 1 and 3, RKPE group had lower C-reactive protein levels (19.87 ± 12.28 vs. 27.05 ± 11.16 mg/L, p < 0.001; 14.88 ± 7.11 vs. 20.73 ± 9.09 mg/L, p < 0.001). During follow-up, RKPE group had higher jaundice clearance rate at 3 (68.18% vs. 51.09%; p = 0.032) and 6 months (78.79% vs. 64.13%; p = 0.047) postoperatively. However, the cholangitis rate within 1 year postoperatively (46.97% vs. 50.00%; p = 0.707), as well as one-year (75.76% vs. 72.83%; p = 0.678) and two-year survival with native liver rates (68.42% vs. 66.67%; p = 0.857), were comparable between two groups.
conclusionsRKPE provided superior technical skill performance and a higher jaundice clearance rate than LKPE, indicating that it may be a better minimally invasive option for BA. In addition, the survival with native liver rate showed no significant difference between the two cohorts, which needs to be confirmed by further study.
