Modified Glissonean pedicle transection vs. hilar dissection in laparoscopic left hemihepatectomy for hepatolithiasis: a propensity score analysis (with video).
Article in Surgical endoscopy, 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
backgroundLaparoscopic anatomical liver resection for hepatolithiasis is frequently complicated by dense hilar adhesions. Traditional hilar dissection (LHDA) is associated with biliary and vascular injury, whereas the standard Glissonean approach can be compromised by stapler failure when impacted stones are present. This study assessed the safety and efficacy of a two-step laparoscopic modified Glissonean approach (LMGA) for left-sided hepatolithiasis.
methodsThis retrospective cohort study evaluated 215 consecutive patients who underwent laparoscopic anatomical left hemihepatectomy for hepatolithiasis between October 2018 and September 2025 (149 LHDA vs. 66 LMGA). Propensity score matching (1:1) yielded 48 well-balanced pairs. Perioperative outcomes, early liver function, stone clearance, and recurrence-free survival (RFS) were compared.
resultsAfter matching, baseline characteristics were similar between groups. The LMGA group had a shorter median operative time than the LHDA group (275 vs. 315 min, P = 0.035) and lower AST levels on postoperative day 3 (40.75 vs. 69.95 U/L, P < 0.001). Blood loss, conversion rates, and morbidity were comparable. The residual stone rate was numerically lower with LMGA, though the difference did not reach statistical significance (2.1 vs. 14.6%, P = 0.065). RFS did not differ significantly between groups (log-rank P = 0.66). In univariable Cox analysis, Child-Pugh class B, elevated preoperative bilirubin, high AST, and longer operative time were associated with shorter RFS, whereas the surgical approach was not.
conclusionsThe "incise‑verify‑transect" LMGA strategy offers a safe and efficient approach to laparoscopic left hemihepatectomy. Direct-vision clearance of impacted stones helps to reduce stapler-related risks, shorten operative time, and promote earlier functional recovery, without increasing perioperative morbidity.
