Robotic-assisted laparoscopic tubal anastomosis: Single institution analysis

Background Tubal anastomosis has similar pregnancy rates regardless of approach. Historically, robotic anastomosis has been associated with increased cost and operative time. We sought to perform a contemporary study of these metrics. Methods One hundred and nine patients were identified who underwent robotic-assisted laparoscopic tubal anastomosis. Retrospective analysis of medical records was performed. Phone survey was conducted. Results The mean operative time decreased from 140.7 +/- 27.0 min in 2013 to 60.0 +/- 9.1 min in 2018, with significant downward trend (p< 0.001). The mean cost was $7153.46 +/- $1484.41. The pregnancy rate was 59% (35/59), and tubal patency rate was 81% (42/52). Seventy-two percent of patients under 37 years became pregnant. Conclusions There is significant improvement in operative time of robotic-assisted tubal anastomosis with surgical experience. Robotic tubal anastomosis outperformed historical metrics of laparoscopy and laparotomy with regard to operative time and cost in this series.
