Abstract

OBJECTIVE: This study aimed to report the first surgery for gynecological diseases using a new robotic platform, the hinotori™, and validate its feasibility in clinical settings. METHODS: The world's first robot-assisted total hysterectomy for a gynecological ailment was carried out at Kagoshima University Hospital in December 2022 utilizing the hinotori™ surgical robot system. Eleven other patients then underwent comparable procedures. The surgical team was certified to execute the procedure and had undergone official hinotori™ training. RESULTS: Preoperative diagnoses indicated five cases of endometrial cancer, four cases of uterine myoma and one case each of atypical endometrial hyperplasia, uterine adenosarcoma and high-grade cervical intraepithelial neoplasia. Median age and body mass index were 51 (range: 38-70) years and 26.9 (range: 17.3-33.3) kg/m2, respectively. Median roll-in, cockpit and operation times were 15 (range: 10-18), 161 (range: 110-225) and 214 (range: 154-287) min, respectively. The median blood loss was 22 (range: 7-83) mL and conversion to laparotomy was not allowed. Only one patient had postoperative pelvic region infection. The median length of hospital stay was 6 (range: 4-10) days. CONCLUSION: Based on our experience with presented 12 cases, robotic surgery with the hinotori™ is a feasible technique of minimally invasive surgery for gynecological diseases.
