[Preliminary experience of transoral robotic surgery in laryngeal and hypopharyngeal tumors with da Vinci surgical system].

Objective: The purpose of this study was to summarize preliminary clinical experience of transoral robotic surgery (TORS) in laryngeal and hypopharyngeal tumors with da Vinci surgical system. Method: Twelve patients were reviewed who were diagnosed with laryngeal ( n =7) and hypopharyngeal tumors ( n =5) and treated with TORS in Beijing Anzhen Hospital from July 1, 2016 to January 31, 2018. Result: Ten cases were male and two cases were female. The median age was 58 years old (ranging from 30 to 81 years). The robotic surgeries were performed successfully on all of the 12 patients. The average surgical time was 31.7 min. The average blood loss was 12.3 ml. The average recovery time for oral intake was 4.6 day. All surgical resection margins were free of carcinoma. Eight cases received neck dissection and 7 cases received adjuvant radiotherapy. There were no perioperative complications. There was no local recurrence, metastasis or death except 1 regional recurrence with a follow-up of 3 to 20 months. Conclusion: TORS is a feasible, safe, minimally invasive, and effective surgical procedure in selected laryngeal and hypopharyngeal tumors.
