About this study

Official title: Preoperative Evaluation of Pulmonary Vascular Anatomy by Augmented Reality (Holograms) in Patients Undergoing Lung Resection

Pulmonary vascular anatomy represents a constant challenge during lung resection, because of its variability in terms of vascular branches and anatomical variations.

Preoperative standard computed tomography is not always sufficient to foresee tricky abnormalities; augmented reality, thanks to holograms creation, may offer additional data on pulmonary vascular anatomy and its relation with neoplastic tissue. The aim of this study is to assess the possibility of correctly predict number, location and potential anomalies of pulmonary vascular anatomy of the lobe to be resected in patients undergoing lung resection for cancer.

Patients will receive standard preoperative oncologic and functional assessment. Preoperative computed tomography (CT) - performed according to a specific protocol - will be performed. CT images will be subsequently elaborated to generate 3D images (holograms). Two radiologists and two thoracic surgeons will analyze CT images and report number of artery and vein branches for the lobe to be resected. Moreover they will report every anatomical variation, according to the normal anatomy. After that, the same two radiologists and thoracic surgeons will analyze the holograms and perform the same analysis as quoted above. Patients will undergo to the planned surgical resection. The operating team will report the exact number of artery and vein branches of the resected lobe as well as every anatomical variation. Preoperative CT and holographic findings of the radiologists and the thoracic surgeons will be matched with the report of the operating team.

Read the detailed description

An augmented reality (AR) system provides the surgeon with computer processed imaging data in real-time via dedicated hardware and software. The projection of AR is made possible by using displays, projectors, cameras, trackers, or other specialized equipment.

At present, the applications of AR are limited by the essential requisite of preoperative 3D reconstructions of medical images. It is possible to create these reconstructions by using commercial or self-made software from the Digital Imaging and Communications in Medicine (DICOM) format . The quality of a reconstruction depends on the quality of input data and the accuracy of the reconstruction system. Such reconstructions can be used for virtual exploration of target areas, planning an elective surgical approach in advance, and for better orientation and navigation in the operative field. AR is especially useful in visualizing critical structures such as major vessels, nerves, or other vital tissues. By projecting these structures directly onto the patient, AR increases safety and reduces the time required to complete the procedure. Moreover Augmented reality proved to be an effective tool for training and skill assessment of surgery residents, other medical staff, or students. Augmented reality can be used effectively for preoperative planning and completion of the actual surgery in timely fashion. The preoperative 3D reconstructed images can be modified and prepared for display in AR systems. Commonly, AR is used for tailoring individually preferred incisions and cutting planes, optimal placement of trocars, or to generally improve safety by displaying positions of major organ components. Another benefit of AR is the ability to aid surgeons in difficult terrain after a neoadjuvant chemotherapy or radiotherapy.

Studies suggest that AR systems are becoming comparable to traditional navigation techniques, with precision and safety sufficient for routine clinical practice. Most problems faced presently will be solved by further medical and technological research. Augmented reality appears to be a powerful tool possibly capable of changing the field of surgery through a rational use. In the future, AR will likely serve as an advanced human-computer interface, working in symbiosis with surgeons, allowing them to achieve even better results. Nevertheless, further advancement is much needed to achieve maximum potential and cost-effectiveness of augmented reality.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • HologramDiagnostic test

    Patient undergoing elective anatomical resection for lung cancer will receive standard preoperative CT scan of the chest (as usual); CT images will be subsequently elaborated by a Holographic computer to generate 3D images (holograms).Two radiologists and two thoracic surgeons will analyze CT images in a standard modality and report number of artery and vein branches for the lobe to be resected, moreover they will report every anatomical variation, according to the normal anatomy.

    After that, the same two radiologists and thoracic surgeons will analyze 3D images by the use of Microsoft Hololens and perform the same analysis as quoted above.

    For each review of the exam performed will be written a digitally signed clinical report to certify the timing of the evaluation and to be able to trace the analysis and any subsequent modifications of the interpretation of the CT images results.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Prediction of the exact number of pulmonary arteries and veins of the lobe to be resected.

    Two different investigator (1 senior radiologist and 1 senior thoracic surgery) evaluate standard preoperative CT scan and indicate the number of pulmonary artery and veins of the lobe to be resected; this will be reported in a dedicated registry. After that, the same investigators will evaluate holograms of the same patients and will report the number of arteries and veins of the lobe to be resected; they will then register these data in the same registry. After the operation, the operating surgeon will report - as usual - the number of the arteries and veins resected during the procedure. Finally the prediction of the investigators obtained only by CT scan evaluation or bay CT scan + holograms evaluation, will be compared with the operatory report.

    Measured: 2020 - 2022
