Evaluation of the effectiveness of preoperative 3D reconstruction combined with intraoperative augmented reality fluorescence guidance system in laparoscopic liver surgery: a retrospective cohort study.

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
objectiveTo evaluate the effectiveness of preoperative 3D reconstruction combined with intraoperative augmented reality fluorescence guidance system in laparoscopic liver surgery by establishing a retrospective cohort study.
methodsA retrospective cohort study was conducted from March 2023 to December 2024, with patients' data from the medical record system. Patients were divided into two groups according to their surgical protocols: 46 cases in the control group (conventional laparoscopic liver surgery) and 50 cases in the observation group (preoperative 3D reconstruction combined with intraoperative augmented-reality fluorescence guiding system in laparoscopic liver surgery). We compared perioperative indexes (operation time, intraoperative bleeding, time to first flatus, drainage tube removal time, hospitalization time), preoperative and postoperative liver function indexes [alanine aminotransferase (ALT), albumin (ALB), total bilirubin (TBIL)], stress indexes [angiotensin II (AT II), norepinephrine (NE), epinephrine (AD)], and complication rates between the two groups.
resultsThe operation time of patients in the observation group was shorter than that of patients in the control group (110.75 ± 20.56 vs. 122.35 ± 20.48 min, 95% CI of difference: 2.52-20.68 min, p = 0.013), and the amount of intraoperative bleeding was less (300.80 ± 32.70 vs. 320.76 ± 35.84 mL, 95% CI of difference: 7.62-32.30 mL, p = 0.002). There was no statistically significant difference in the comparison of time to first flatus, drain removal time, hospitalization time and complication rate between the two groups (p > 0.05). Preoperatively, the comparison of ALT, ALB, TBIL, AT II, NE, AD levels of patients in the two groups were not statistically significant (p > 0.05); postoperatively, the AT II, NE, AD levels of patients in the observation group were lower than those of patients in the control group, with statistically significant differences (p < 0.001), while the differences in ALT, ALB, TBIL levels were not statistically significant (p > 0.05). For malignant cases, the R0 resection rate was similar between groups (92.3% vs. 89.5%, p = 0.724).
conclusionPreoperative 3D reconstruction combined with intraoperative augmented reality fluorescence guidance system is potentially beneficial for laparoscopic liver surgery, which can modestly shorten the operation time, reduce intraoperative bleeding, and alleviate postoperative stress reactions.
