@entity1104 ( @entity1104 ) with the da Vinci Surgical System has been used for the removal of pharyngeal and @entity5 with the objective to improve functional and aesthetic outcomes without worsening survival. While @entity1104 has been approved in many countries, Japan's FDA has not yet done so. Our hospital started using @entity1104 with the approval of the Ethical Review Board and the Minimum Invasive Surgical Center Committee at Tottori University. No surgical outcomes of @entity1104 for Japanese @entity1 with @entity135 have been reported in Japan. This paper deals with the outcomes and feasibility of @entity1104 for Japanese @entity1 with @entity5 at our institution. @entity1104 was performed for 10 @entity1 with T1, T2, T3 oropharyngeal and @entity957 between 2013 and 2014. This is a single-institutional study. @entity1104 could be completed for all cases, except one @entity1 that was not candidate, and no intraoperative conversion to an open surgical procedure was required. Five @entity1 underwent neck dissection, two of them concurrent and three staged. Of all @entity1 , positive surgical margins were detected in two. The average @entity190 including neck dissection was 21.5      33.4  ml, the operation time was 183      36  min and the console time was 103      22  min. No tracheostomy had been performed either pre- or postoperatively, and there was no difference between preoperative and postoperative swallowing functions. In this single-institutional preliminary study, we demonstrated that @entity1104 is a feasible and safe treatment. A clinical multi-institutional study of @entity1104 for @entity5 has been approved as an advanced medical system study and is under way. In the near future, it is expected that the efficacy and safety of @entity1104 for @entity5 will be confirmed as the result of this multiple-institutional clinical study in Japan.
