Abstract

BackgroundThe purpose of this study was to investigate the potential of a combination of 3D mixed-reality visualization of medical images using CarnaLife Holo (MedApp, Poland) system as a supporting tool for innovative, minimally invasive surgery/irreversible electroporation—IRA, Nano-Knife), microwave ablation (MWA)/for advanced gastrointestinal tumors. Eight liver and pancreatic tumor treatments were performed. In all of the patients undergoing laparoscopy or open surgery volume and margin were estimated by preoperative visualization. In all patients, neoplastic lesions were considered unresectable by standard methods.MethodsPreoperative CT or MRI were transformed into holograms and displayed thanks to the HoloLens 2. During operation, the surgeon’s field of view was augmented with a 3D model of the patient’s relevant structures.ResultsThe intraoperative hologram contributed to better presentation of tumor size and locations, more precise setting of needles used to irreversible electroporation and for determining ablation line in case of liver metastases. Surgeons could easily compare the real patient's anatomy to holographic visualization just before the operations.ConclusionsThe combination of 3D mixed-reality visualization using CarnaLife Holo with IRA, MWA and next systemic treatment (chemotherapy) might be a new way in personalized treatment of advanced cancers.

Highlights

  • The fields of 3D image-guided interventional therapies are rapidly growing, both in technical development and clinical adoption

  • The multidisciplinary team prepared the visualization of medical data on the basis of computed tomography (CT) and/or magnetic resonance imaging (MRI)

  • In the preoperative planning, the multidisciplinary team prepared the visualization of medical data on the basis of computed tomography (CT) and/or magnetic resonance imaging (MRI)

Summary

Introduction

The fields of 3D image-guided interventional therapies are rapidly growing, both in technical development and clinical adoption. For many cancer patients there is no chance for surgical removal due to difficult-to-reach or unresectable neoplasm. This situation puts pressure on the multidisciplinary teams to find alternative methods of treatment that achieve a response rate and prolong a patient’s lifespan and will improve the quality of life. The purpose of this study was to investigate the potential of a combination of 3D mixed-reality visualization of medical images using CarnaLife Holo (MedApp, Poland) system as a supporting tool for innovative, minimally invasive surgery/irreversible electroporation—IRA, Nano-Knife), microwave ablation (MWA)/for advanced gastrointestinal tumors. Conclusions The combination of 3D mixed-reality visualization using CarnaLife Holo with IRA, MWA and systemic treatment (chemotherapy) might be a new way in personalized treatment of advanced cancers
