“…In einer systematischen Literaturrecherche von Shapey und Kol legen konnten bisher 13 Studien oder Fallberichte über der klini schen Anwendung von HSI in der operativen Disziplin identifiziert werden [21]. Dabei waren lediglich 3 Berichte aus dem Fachbereich der plastischen Chirurgie vertreten [22][23][24]…”

Zusammenfassung Hintergrund Seit der Erstbeschreibung einer lokoregionären Lappenplastik zur Nasenrekonstruktion im 6. Jahrhundert v. Chr. durch den indischen Arzt Sushruta Samhita sind diese ein fester Bestandteil in der Wiederherstellungschirurgie geworden. Neben der konsequenten Weiterentwicklung chirurgischer Operationsmethoden wurden die zu Grunde liegenden physikalischen Messmethoden des Lappenmonitoring in den letzten Dekaden stetig weiterentwickelt. Das Hyperspektralimaging (HSI) stellt eine neue quantitative Messmethode zur Beurteilung der Gewebeperfusion dar. Ziel Das Ziel dieser Arbeit ist die Evaluation des HSI als Monitoringverfahren nach lokoregionärer Defektdeckung. Patienten und Methode Bei insgesamt 16 Patienten wurde nach gefäßgestieltem Gewebetransfer die Sauerstoffsättigung, der Hämoglobingehalt sowie der Wassergehalt von Haut, Monitorinsel und nekrotischen Lappenarealen am 1. bis 7. postoperativen Tag gemessen. Die erhobenen Daten wurden statistisch deskriptiv ausgewertet und grafisch ausgearbeitet. Ergebnisse Das HSI zeigte einen erhöhten Hämoglobingehalt, eine Abnahme der Sauerstoffsättigung sowie des Wassergehaltes in den nekrotischen Lappenarealen im Vergleich zur vitalen Monitorinsel und zur gesunden Haut. Monitorinsel und vitale Hautareale wiesen eine nahezu identische Werteverteilung auf. Schlussfolgerung HSI erlaubt die sichere, kontaktfreie und sofortige Bestimmung der Gewebeperfusion von transferierten Gewebearealen bei Patienten nach lokoregionärer Defektdeckung. Daher erscheint die Verwendung von HSI im Rahmen des postoperativen Lappenmonitorings sinnvoll.

“…Three other studies have evaluated how intraoperative tissue oxygenation maps generated from HSI data might guide skin flap reconstruction in breast , oral cancer and vascular surgery. These studies all demonstrated a correlation between the HSI‐oxygenation data and the expected dynamic surgical changes however post‐operative follow‐up data relating to the end‐organ's viability was not available.…”

Multispectral and hyperspectral imaging (HSI) are emerging optical imaging techniques with the potential to transform the way surgery is performed but it is not clear whether current systems are capable of delivering real-time tissue characterization and surgical guidance. We conducted a systematic review of surgical in vivo label-free multispectral and HSI systems that have been assessed intraoperatively in adult patients, published over a 10-year period to May 2018. We analysed 13 studies including 7 different HSI systems. Current in-vivo HSI systems generate an intraoperative tissue oxygenation map or enable tumour detection. Intraoperative tissue oxygenation measurements may help to predict those patients at risk of postoperative complications and in-vivo intraoperative tissue characterization may be performed with high specificity and sensitivity. All systems utilized a line-scanning or wavelength-scanning method but the spectral range and number of spectral bands employed varied significantly between studies and according to the system's clinical aim. The time to acquire a hyperspectral cube dataset ranged between 5 and 30 seconds. No safety concerns were reported in any studies. A small number of studies have demonstrated the capabilities of intraoperative in-vivo label-free HSI but further work is needed to fully integrate it into the current surgical workflow.
