Innovative technologies in pediatric surgical oncology: a 3D4K operating exoscope in open abdominal surgery

3D4K surgical exoscopes are a new class of tools for intraoperative imaging and magnification in surgery. The purpose of this work was to improve the quality of surgical treatment of children with malignant solid tumors through the introduction of an innovative method into surgical practice – a surgical exoscope. The first results of applying a 3D4K exoscope – a revolutionary technology that combines microsurgery and video-assisted open surgery – for the surgical treatment of abdominal tumors in children are reported in this paper. For the first time, an operating team had an opportunity to see the surgical field on a monitor with high magnification: 3D images with 4K resolution. Two 3D4K exoscope-assisted operations were performed: surgery for relapsed intra-abdominal desmoplastic small round cell tumor in a 9-year-old child and surgery for bilateral nephroblastoma in a 5-year-old girl. The latter patient underwent organ-sparing surgeries: partial nephrectomy of the right kidney and indocyanine green fluorescence-guided partial nephrectomy of the left kidney. The patient's parents gave consent to the use of their child's data, including photographs, for research purposes and in publications. The obtained results showed that 3D4K exoscopes are highly effective in abdominal surgeries for solid tumors in children.
