Postoperative outcomes with minimally invasive minor hepatectomy based on ECOG performance status - analysis of multi-institutional database.
Article in Surgical endoscopy, 2025. 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
objectiveMinimally invasive liver resection (MILR) is associated with fewer postoperative complications compared to open liver resection. Eastern Cooperative Oncology Group (ECOG) performance status (PS) is a fast, reproducible patient selection tool used to guide therapy. We compared patient outcomes after MILR by ECOG PS.
methodsNon-cirrhotic patients undergoing MILR resection at one of 14 North American healthcare centers were identified from the Americas Minimally Invasive Liver Surgery (AMILES) database (2010-2024). Perioperative outcomes were compared between ECOG1 and ECOG2 patients. Multivariable analysis (MVA) was used to identify factors independently associated with postoperative complications.
resultsOf 4,181 patients, 486 met our inclusion criteria. Median patient age was 62 years. Four-hundred twenty-eight patients (88.1%) were ECOG1. Overall postoperative complication rate was not lower in ECOG 1 patients compared to ECOG 2 patients on univariate (20.3 vs. 29.1%, p = 0.17), and MVA (aOR 0.60, p = 0.14). Robotic versus laparoscopic approach (aOR 0.52, p = 0.03) and use of intraoperative ablation versus no ablation (aOR 0.38, p = 0.03) were associated with decreased odds of postoperative complications. Intraoperative conversion from MILR to open was associated with increased odds of postoperative complications (aOR 2.22, p = 0.04).
conclusionIn non-cirrhotic patients with ECOG2 performance status, minimally invasive minor liver resection may be considered with an acceptable complication rate similar to ECOG1 patients.
