Association between surgical difficulty and tumor location based on subsegments of the Glisson branches in laparoscopic liver resection.
Article in Annals of gastroenterological surgery, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
Background: Laparoscopic liver resection has a steep learning curve, and multiple difficulty-scoring systems have been proposed to support safe implementation. Though the IWATE scoring system is widely used, the rationale for its tumor location score is unclear. The objective of our study was to establish a more accurate definition of tumor location based on subsegments of the Glisson branches. Methods: We included 176 patients who underwent laparoscopic liver resection between January 2017 and February 2024, excluding those who underwent multiple or concomitant resections of other organs. Tumor location was defined by the most proximal subsegment of the Glisson branches (1sp, Spiegel; 1pc, para-caval; 1cp, caudate process; 3a, apical; 3b, basal; 4a; 4b; 5v, ventral; 5d, dorsal; 6v; 6d; 6 L, lateral; 7v; 7d; 8v; 8d). Results: Within each segment, comparing operative time between subsegments showed significant differences, except for S1 (3a vs. 3b, Conclusions: There are significant differences in the difficulty of laparoscopic liver resection among subsegments. More detailed scoring based on subsegments may improve accuracy, and we propose a new scoring system.
