The impact of 3-dimensional models and surgical navigation for open liver surgery.

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
purposeUnderstanding patient-specific liver anatomy is crucial for patient safety and achieving complete treatment of all tumors during surgery. This study evaluates the impact of the use of patient-specific 3D liver models and surgical navigation on procedural complexity in open liver surgery.
methodsPatients with colorectal liver metastases scheduled for open liver surgery were included between June 2022 and October 2023 at the Netherlands Cancer Institute. Patient-specific 3D liver models could be used upon request during the surgical procedure. Subsequently, surgeons could request additional surgical navigation by landmark registration using an electromagnetically tracked ultrasound transducer. Postoperatively, surgeons assessed the impact of the use of the model and navigation on procedural complexity on a scale from 1 to 10.
results35 patients were included in this study, with a median number of 8 (ranging from 3 to 25) tumors. 3D models were utilized in all procedures. Additional navigation was requested in 21/35 of patients to improve intraoperative planning and tumor localization. The mean procedural complexity score with navigation was 4.3 (95% CI [3.7, 5.0]), compared to 7.8 (95% CI [6.6, 9.0]) with the 3D model alone. Both visualization methods improved lesion localization and provided better anatomical insight.
conclusion3D models and surgical navigation significantly reduce the complexity of open liver surgery, especially in patients with bilobar disease. These tools enhance intraoperative decision-making and may lead to better surgical outcomes. The stepwise implementation of the visualization techniques in this study underscores the added benefit of surgical navigation beyond 3D modeling alone, supporting its potential for broader clinical implementation.
