Evolution of laparoscopic liver resection in the last two decades: lessons from 2000 cases at a referral Korean center.
Article in Surgical endoscopy, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 papers, 3 of them syntheses 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
BACKGROUND AND
aimsLaparoscopic liver resection (LLR) has evolved to become the standard surgical approach in many referral centers worldwide. The aim of this study was to analyze how LLR evolved at a single high-volume referral center since its introduction, more than two decades ago.
methodsData from all consecutive LLR between January 2003 and September 2022 at the Seoul National University Bundang Hospital were analyzed. Perioperative outcomes were compared between three time periods, with major technological innovations considered as landmarks: before introduction of laparoscopic-US and CUSA (2003-2006), before (2006-2015) and after (2015-2022) introduction of high-definition scope.
resultsDuring the analyzed time periods the number of technically challenging procedures increased from 39.2 to 61.1% (p < 0.001). The most recent period showed shorter median operation time (from 267.5' to 175', p < 0.001), lower median estimated blood loss (EBL) (from 500 to 300 ml, p < 0.001), lower intraoperative transfusions (from 33.8 to 9.3%, p < 0.001), shorter median postoperative hospital stay (from 12 to 6 days, p < 0.001). The time period, a technical major resection and an underlying liver cirrhosis were found to be the associated with longer operation time (p < 0.001) in the multivariable linear regression analysis, while tumor size, technically major surgeries and liver cirrhosis were associated with higher EBL (p < 0.001).
conclusionDuring the last two decades, the indications for patients undergoing LLR have expanded significantly, including more and more challenging procedures and frail patients. Despite such challenges, perioperative outcomes improved, although technically major procedures, cirrhotic patients and huge tumors have still to be considered challenging situations.
