Exploring the advantages of mixed reality technology in Robot-assisted laparoscopic partial adrenalectomy.
Article in World journal of surgical oncology, 2026. 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
background and purposeAs an emerging interactive display technology, mixed reality(MR) allows for the integration of multi-dimensional virtual objects with the real world, enhancing the precision of surgical operations. This technology has demonstrated significant value in renal tumor surgeries, but its application in adrenal tumor surgeries remains unclear. This study aims to investigate the clinical efficacy and potential benefits of mixed reality technology in robot-assisted laparoscopic partial adrenalectomy (RALPA) for treating adrenal tumors. PATIENTS AND
methodsA total of 82 eligible patients who underwent RALPA for adrenal tumors at the Second Affiliated Hospital of Nanchang University from September 2020 to October 2024 were included in this retrospective study. The patients were divided into two groups based on their preoperative diagnosis and treatment: 32 patients in the mixed reality (MR)group and 50 patients in the traditional CT imaging (control) group. All patients received bilateral adrenal gland CT scans, both plain and enhanced. The MR group utilized CT data to create a virtual model, which was then used for surgical planning and intraoperative guidance through a 3D tablet computer and Hololens glasses. Preoperative variables and perioperative indicators were collected to evaluate surgical outcomes in both groups.
resultsPostoperative statistics indicated that the operation time for the MR group was significantly shorter than that of the control group (102.00(98.00 103.00) minutes vs. 103.50(101.00 106.75) minutes, p = 0.017). The estimated intraoperative blood loss was also lower in the MR group compared to the control group (58.50(53.00 63.00) ml vs. 77.00(72.00 86.00) ml, p < 0.001). Additionally, the recovery time for gastrointestinal function in the MR group was significantly shorter than that in the control group (28.00(26.00 30.00) hours vs. 32.00(30.00 35.00) hours, p < 0.001). While there was no significant difference in the incidence of postoperative complications between the two groups, the postoperative hospitalization duration for patients in the MR group was significantly shorter (4.00(4.00 5.00) days vs. 5.00(5.00 5.00), p = 0.004). No statistically significant difference was observed in the spectrum of potential adrenal diseases between the MR and control groups (p > 0.05).
conclusionCompared to traditional CT imaging, RALPA guided by mixed reality technology may be associated with a modest reduction in surgical time, a decrease in intraoperative blood loss, and faster recovery of gastrointestinal function. However, the clinical significance of these observed differences remains limited, and the findings should be interpreted cautiously due to the retrospective study design. Prospective controlled studies are needed to confirm whether MR technology provides a true clinical advantage over conventional imaging in adrenal surgery.
