“…4K endoscope combined with NBI technology 4 has in our opinion the potential to start a revolution in skull base surgery, even if Akutsu used a flexible scope and standard HD monitor after removal of pituitary adenoma to check if there is still pathology in a series of 25 cases 5 .…”

Negli ultimi venti anni la chirurgia endoscopica del basicranio ha osservato continui sviluppi tecnici e tecnologici. Lendoscopia 3D e l alta definizione (HD) 4K hanno fornito grandi vantaggi in termini di visualizzazione e di risoluzione spaziale. L ultra HD 4K, recentemente introdotta nella pratica clinica, determinerà i prossimi passi soprattutto nella chirurgica endoscopica del basicranio. I pazienti sono stati operati attraverso un approccio transnasale transfenoidale endoscopico, utilizzando un endoscopio Olympus NBI 4K UHD con ottica 4 mm 0 ° Ultra Telescope, lampada allo xeno 300 W (CLV-S400) predisposto per la tecnologia narrow band imaging (NBI) collegato con una videocamera ad un alta qualità unità di controllo (OTV-S400 - VISERA 4K UHD) (Olympus, Tokyo, Giappone). Due schermi, un 31 Monitor - (LMD-X310S) e quello principale ultra-HD 55 a pollici ottimizzati per la riproduzione immagini UHD (LMD-X550S). In casi selezionati abbiamo usato un sistema di navigazione (Stealthstation S7, Medtronic, Minneapolis, MN, Stati Uniti). Abbiamo valutato 22 adenomi ipofisari (86,3% macroadenomi; 13,7% microadenomi). Il 50% non erano secernenti (NS), 22,8% GH, 18,2% ACTH, 9% PRLsecernenti. 3/22 erano recidive. Nel 91% dei casi abbiamo raggiunto la rimozione totale, mentre nel 9% la resezione subtotale. Un followup medio di 187 giorni, durata media del ricovero era 3,09 ± 0,61 giorni. Tempo chirurgico 128,18 ± 30,74 minuti. Abbiamo avuto solo 1 caso di fistola intraoperatoria a basso flusso senza ulteriori complicazioni nel follow up. Il 100% dei casi non ha richiesto emotrasfusione. La visualizzazione e lalta risoluzione del campo operatorio hanno fornito una vista dettagliata di tutte le strutture anatomiche e patologie e permesso il miglioramento della sicurezza e lefficacia della procedura chirurgica. Il tempo operatorio è stato simile a quello dellendoscopio HD standard 2D e 3D, come la fatica fisica era paragonabile ad altri in termini di ergonomicità e peso.

“…Furthermore, image artefacts can lead to false positives, so iMRI is not recommended by the Congress of Neurological Surgeons [248]. In recent years, there has been much research into intraoperative optical imaging technologies for transsphenoidal surgery, including narrow band imaging (NBI) [256], 4K imaging [257], ICG fluorescence imaging [258,259] and optical molecular imaging (OMI) with a fluorescent folate analogue [260].…”

“…Narrow band imaging (NBI) was described in detail in Section 2.2.2B. On standard NBI, the pituitary gland appears as an arabesque pattern due to the rich vasculature, whereas the tumour has no particular pattern of enhancement [256]. A recently released 4K ultra-high definition (UHD) NBI endoscope (VISERA, Olympus, Japan) allows 3840 ´ 2160 pixel UHD imaging with NBI, allowing high resolution imaging of the microvasculature [257].…”

First, I would like to thank my supervisor, Sarah Bohndiek, for giving me the opportunity to join VISIONLab in 2014. I could not have asked for a better supervisor. Throughout my time in her lab, Sarah made time to provide scientific advice and feedback and supported me in purchasing equipment, in travelling to conferences and in my professional development. Despite the lab expanding rapidly, Sarah's schedule, along with her office door, have remained open. Her openness, efficiency, and the apparent ease with which she carries out her work is inspirational and these qualities have cultivated a similarly efficient yet relaxed atmosphere in VISIONLab. Never have I felt the crippling pressure of my supervisor bearing down upon me, a feeling all too often described by my peers.Still, experiments failed. Equipment broke. Code crashed. During these times, I am grateful to have been surrounded by supportive colleagues. As a novice to research I am thankful that James Joseph and George Gordon were so willing to show me the ropes. I would also like to acknowledge the support of my exceptional clinical collaborators, especially Massimiliano di Pietro, Wladyslaw Januszewicz and James Tysome, whose support and patience has helped facilitate clinical translation of my work. I am grateful to have worked alongside Siri Luthman, tackling our problems together in an otherwise desolate optics lab.I would also like to thank my colleagues turned close friends. To Isa, James and Judith, for conversations over coffee, in the car and over beers. Your warm words were always reassuring. To Abby, for helping me to keep calm, and for reading and correcting this thesis. To Michal, for all the fun we shared over the years. Further thanks go to my friends in college, especially Andrea, for the relaxing evenings watching trash TV, and Alexis, for the formals and nightsout which made the end of the week worth looking forward to. And a huge thank you to Lina, for her love and support in the final stretch.Sadly, my big nan-nan is not here to see me complete my thesis. She is dearly missed and I am sure she would be immensely proud, as are my other grandparents. Their pride and love have spurred me on throughout my research. I express immense gratitude to my mum, dad and brother, Aaron. The weekends we spent in Cambridge, and at home, helped to remind me of the world outside the Cambridge bubble. Even in their absence, their love, support and advice stayed with me every step of the way, strengthening me in challenging times. The lessons my parents have taught me, and the example they set, have shaped all aspects of who I am and where I am today, and I will be forever grateful.Finally, I would like to acknowledge the funding from the CRUK-EPSRC Cancer Imaging Centre in Cambridge and Manchester, without which I could not have carried out this work. These thanks extend to the millions of people whose generous donations ensure this work continues.
