Long term results after supraglottic tumor resection with the Medrobotics Flex​ Robotic system

Introduction Supraglottic tumors can be a surgical challenge especially if exposure is difficult. With the Medrobotics Flex​ Robotic system excellent visualisation of the hypopharynx and larynx can be achieved through a flexible camera system. In the present study long term results after supraglottic tumor resection with the Medorobotics Flex​ Robotic System are evaluated.

Methods Since 2015 a total of 31 patients underwent supraglottic tumor resection with the Medrobotics Flex​ Robotic system. To evaluate long term outcome only patients with a minimum follow up of 3 years were included. Rate of recurrence of the primary tumor site as well as overall survival were investigated.

Results A total of 21 patients had a follow up of at least 3 years (maximum 6 years). T-status ranged from T1 (n=8), T2 (n=9) and T3 (n=4). 4 patients were lost to follow up. A total of 5 patients passed away. All of these 5 patients did not have recurrent local disease at the last follow up. One patient deceased 2 months postoperatively due to a pulmonary embolism. One patient deceased due to a secondary carcinoma of the esophagus. In 3 patients the exact cause of death is not documented, however, no recurrent disease was documented in the last follow up.

Surgery of supraglottic tumors with the Medrobotics Flex​ Robotic system allow for an excellent local tumor control. However, comorbidities and secondary carcinomas limit long term survival.
