Role of liver augmentation prior to hepatic resection - a survey on standards, procedures, and indications in Germany, Switzerland, and Austria.
Article in Langenbeck's archives of surgery, 2024. 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
purposeFor primary and secondary liver tumors oncological resection remains a chance of cure. Augmentation of functional liver tissue may be necessary to preserve sufficient future liver remnant (FLR). Clinical decision-making on liver augmentation techniques and indications may differ internationally. Thus, this study aims to identify standards of liver augmentation in hepato-pancreatico-biliary (HPB) centers in Germany, Switzerland, and Austria.
methodsUsing a web-based survey, 48 hospitals in Germany, Switzerland, and Austria were invited to report their surgical indication, standard procedures, and results of liver augmentation.
resultsForty (83.3%) of the hospitals invited participated. Most of the hospitals were certified liver centers (55%), performing complex surgeries such as liver transplantation (57.5%) and ALPPS (80%). The standard liver augmentation technique in all countries was portal vein embolization (PVE; 56%), followed by ALPPS (32.1%) in Germany or PVE with hepatic vein embolization (33.3%) in Switzerland and Austria. Standard procedure for liver augmentation did not correlate with certification as liver center, performance of liver transplantation or ALPPS. Surgical indication for PVE varied depending on tumor entity. Most hospitals rated the importance of PVE before resection of cholangiocarcinoma or colorectal metastases as high, while PVE for hepatocellular carcinoma was rated as low.
conclusionThe survey gives an overview of the clinical routine in HPB centers in Germany, Austria, and Switzerland. PVE seems to dominate as standard technique to increase the FLR. However, there is a variety in the main indication for liver augmentation. Further studies are necessary evaluating the differing PVE techniques for liver augmentation.
