Multicenter study on right Glissonean pedicle management in laparoscopic right hepatectomy: main trunk vs. sectoral pedicle transection approaches.

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
backgroundDuring laparoscopic right hemihepatectomy (LRH), two principal techniques for right Glissonean pedicle management are employed: sectoral pedicle transection of the right anterior and posterior sectional pedicles, or main trunk transection of the entire pedicle. It remains controversial whether these approaches differ in safety and efficacy. This study was therefore designed to compare the perioperative outcomes of these two techniques to determine if significant differences exist.
methodsThis was a multicenter retrospective analysis of 246 patients with hepatocellular carcinoma (HCC) undergoing LRH, with data collected from 8 centers. Outcome measurements were intraoperative blood loss, operative time and postoperative complications, etc. We conducted propensity score matching (PSM) analysis to evaluate perioperative outcomes.
resultsIn this study, 90 HCC patients used the sectoral pedicle transection approach, while 156 HCC patients used the main trunk transection approach. 90 patients with well-matched baseline levels were enrolled in each group after 1:1 PSM. The sectoral pedicle transection group had less surgical margin (mean, 11.32 vs. 15.02 mm, P = 0.0024). However, the intraoperative blood loss, operative time, postoperative hospital stays, and overall postoperative complications were comparable between the two groups. Additionally, there was no significant difference in the incidence of biliary strictures or bile leakage between the two groups.
conclusionThe main trunk and sectoral pedicle transection approach for LRH in HCC patients were both safe and effective when performed by experienced surgeons. In our study, the main trunk transection technique provided the technical advantage of a wider surgical margin. Furthermore, it was not associated with an increased incidence of biliary complications.
