Single-Incision Hysterectomy Outcomes With and Without Robotic Assistance.

OBJECTIVE

To evaluate the differences in operative time and postoperative complications for total laparoscopic hysterectomy (TLH) performed using conventional laparoendoscopic single-site surgery (LESS) versus a robotic-assisted LESS approach.

METHODS

A retrospective study was conducted of all cases of conventional LESS TLH (n = 47) and robotic LESS TLH (n = 129) for benign gynecologic conditions performed from November 2014 to October 2017. Patient characteristics, operative time for hysterectomy, estimated blood loss, duration of hospitalization, and short-term postoperative complications were compared using appropriate parametric and nonparametric statistical tests.

RESULTS

Conventional LESS TLH cases had a 16.36-minute longer mean operative time for hysterectomy ( < .01). No difference was found in uterine weight, estimated blood loss, hospitalization, or incidence of postoperative complications when LESS TLH was performed with or without robotic assistance. When comparing uterine weight < 100 g, conventional LESS TLH cases had significantly greater operative time than the robotic LESS TLH cases (78.10 ± 23.97 minutes vs. 59.97 ± 35.17 minutes, < .01). When comparing uterine weight > 100 g, conventional LESS TLH cases again had significantly greater operative time than the robotic LESS TLH cases (98.73 ± 50.16 minutes vs. 80.00 ± 42.97 minutes, < .01). There was no difference in postoperative complications.

CONCLUSION

Robotic single-incision laparoscopy can result in decreased operative time compared to a conventional LESS approach. Robotic-assisted and conventional LESS are similar in rate of postoperative complications, if performed by surgeons with abundant LESS experience.
