Abstract
Background
Colorectal cancer is the third most common cancer worldwide. Current treatment approaches are multidisciplinary, including neoadjuvant chemoradiotherapy for rectal cancer. Several studies have reported an improvement in surgical techniques and in new devices facilitating better pre- and intraoperative staging.
Objectives
Since its first application in 2002, robotic surgery has progressed steadily, offering good surgical results and better oncological outcomes. Currently, many studies and reviews have confirmed its safety and feasibility for colorectal cancer.
Materials and methods
Robotic technology simplifies surgical maneuvers thanks to the three-dimensional magnification and stable vision, convenient mobility of the robotic arms, endowrist instruments with seven degrees of freedom, ambidextrous capability, tremor filtering, and indocyanine green fluorescence imaging.
Results
Regarding the oncological outcome, the robotic technique is equivalent to the laparoscopic approach; however, a lower recurrence rate has been achieved with the robotic approach in extended lymphadenectomy as part of complete mesocolic excision for right colonic cancer and total mesorectal excision for low rectal tumors.
Conclusion
Colorectal robotic surgery has progressively improved worldwide. Its advantages are related not only to better oncological outcomes, but also to improvements in terms of detection, accurate diagnosis, and staging.
Zusammenfassung
Hintergrund
Kolorektale Karzinome sind die dritthäufigsten Karzinome weltweit. Gegenwärtiger Therapiestandard ist die multimodale Behandlung, einschließlich der neoadjuvanten Radiochemotherapie des Rektumkarzinoms. Eine Vielzahl von Studien befasst sich mit der Fortentwicklung der chirurgischen Technik und neuen Gerätschaften auch zur Verbesserung des prä- und intraoperativen Stagings.
Ziel der Arbeit
Die roboterassistierte Chirurgie hat sich seit dem ersten Einsatz in der kolorektalen Chirurgie im Jahr 2002 stetig weiterentwickelt und verbessert. Gegenwärtig haben bereits viele Studien die Sicherheit und Machbarkeit der roboterassistierten Behandlung des kolorektalen Karzinoms belegt.
Material und Methoden
Die Robotertechnologie vereinfacht die chirurgische Präparation aufgrund von 3‑D-Optik mit Vergrößerung auf stabiler Plattform, guter Beweglichkeit der Roboterarme, Endowrist-Instrumenten mit 7 Freiheitsgraden, Beidhändigkeit, Beseitigung von Tremor und Einsatz der Indozyaningrün(ICG)-Fluoreszenz.
Ergebnisse
Bezüglich des onkologischen Ergebnisses ist die Robotertechnologie der laparoskopischen Technik mindestens gleichwertig. Der Einsatz des Roboters vermag bei der erweiterten Lymphadenektomie im Rahmen der kompletten mesokolischen Exzision (CME) wegen eines rechtsseitigen Kolonkarzinoms und bei der totalen mesorektalen Exzision (TME) wegen eines tiefen Rektumkarzinoms die Rezidivrate zu senken.
Schlussfolgerung
Die kolorektale Roboterchirurgie findet weltweit zunehmende Verbreitung: die Vorteile liegen nicht nur im besseren onkologischen Ergebnis, sondern auch in der Verbesserung im Hinblick auf Erkennung, korrekter Diagnosestellung und Staging.
