Outcomes of bile duct-guided right hepatic inflow occlusion and extended procedures in laparoscopic liver surgery.
Article in BMC gastroenterology, 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
objectiveThis study aimed to assess the safety and feasibility of bile duct-guided right hepatic inflow occlusion and associated extended procedures in laparoscopic liver surgery (LLS).
methodsA cohort of 23 patients who underwent laparoscopic right hemihepatectomy, which involved laparoscopic dissection and occlusion of the right hepatic artery and right portal vein using the bile duct-guided approach (primary procedure) were included in this study. Ten additional patients with insufficient future liver remnant (FLR) volume in the left hemiliver, as determined by preoperative assessment, underwent a staged approach. In the first stage, laparoscopic right portal vein ligation (LRPVL) was performed via the bile duct-guided approach (extended procedure). Following an observation interval, and upon confirmation of sufficient hypertrophy of the left hemiliver, either laparoscopic or open right hemihepatectomy, with or without combined procedures, was performed as the second stage.
resultsAll procedures were completed without major postoperative complications. In the primary procedure cohort, the mean operative duration was 4.2 ± 0.4 h, the mean right hepatic portal occlusion time was 18 ± 8 min, intraoperative blood loss ranged from 200 to 400 ml, and the length of hospital stay was 7–12 days. For the first-stage extended procedure, the mean operative duration was 1.2 ± 0.3 h, the mean right portal vein occlusion was 14 ± 5 min, intraoperative blood loss ranged from 20 to 80 ml, and the length of hospital stay was 3–5 days. The second-stage procedure was performed 3 to 5 days after the most recent three-dimensional imaging assessment. The mean left liver volume increased from 456.14 ± 84.42 cm3 before the first-stage procedure to 649.06 ± 102.26 cm3 before the second-stage procedure, corresponding to a 44 ± 18% increase.
conclusionBile duct-guided right hepatic inflow occlusion and its extended procedures demonstrated safety and feasibility in the context of LLS.
