当院での婦人科ロボット支援下手術と従来の腹腔鏡手術の周術期予後についての検討

Objectives: Robot-assisted gynecologic surgery is widely used throughout Japan. However, detailed reports examining the perioperative outcomes of robotic surgery and conventional laparoscopy in gynecology in Japan are limited. Hence, we aimed to compare the outcomes of robotic and laparoscopic surgeries. Methods: Patients with benign disease and endometrial cancer who underwent robotic (robotic group) or conventional laparoscopic (lap group) surgery by the same surgeon at our hospital between 2020 and 2022 were included. Clinical background, surgical information, and postoperative histological examination findings were evaluated. Results: There were 35 (24 benign, 11 endometrial cancer) and 47 (33 benign, 14 endometrial cancer) cases in the robotic and laparo groups, respectively. There were no significant differences in operative time, blood loss, or postoperative complications. The median (range) organ weight in the lap group was 260 g (60-1127), which was significantly larger than that in the robot group 162 g (46-551). The robot group had a significantly greater head-down angle [19° (15-21°) vs. 18° (10-20°)] and pneumoperitoneum pressure [10 mmHg vs. 10 mmHg (8-10)] than the lap group had. Conclusion: Although there was no difference in the safety between robotic and conventional laparoscopic surgery, removal of larger uterus' tended to be performed via conventional laparoscopy.
