Robotic single‐port hysterectomy versus robotic multisite hysterectomy in benign gynecologic diseases: A retrospective comparison of clinical and surgical outcomes

Abstract

AbstractBackgroundThis study aimed to compare clinical and surgical outcomes of robotic single‐port hysterectomy (RSPH) using the da Vinci® SP surgical system and robotic multisite hysterectomy (RMSH) with the da Vinci Xi system in benign gynecologic disease.MethodsThe retrospective study included 134 patients who underwent RSPH or RMSH between November 2019 and December 2020. Total operation time, amount of blood loss, and the change in hemoglobin (Hb) after surgery and the weight of the removed uteri were also measured. Data on complications such as post‐operative fever and length of hospitalization were also compared and analyzed.ResultsThere was no significant difference in the total operation time between the two groups, although the operation time was slightly longer in the RSPH group. Results in the RSPH group were superior to the RMSH group in docking time and wound incision time (1.67 ± 0.79 vs. 5.46 ± 2.25 min, p‐value <0.01; 6.48 ± 4.29 vs. 9.10 ± 4.64 min, p‐value <0.01, respectively). On the other hand, wound suture time took longer in the RSPH group (18.12 ± 5.66 vs. 10.69 ± 3.18 min, p‐value <0.01). The weights of the removed specimens were higher in the RMSH group (302.64 ± 190.56 vs. 369.24 ± 181.70 g, p‐value <0.04). The amount of blood loss during surgery and the difference in hemoglobin (Hb) before and after surgery were less in the RSPH group (97.39 ± 113.79 vs. 224.93 ± 152.29 mL, p‐value <0.01, 1.51 ± 1.08 vs. 2.54 ± 1.08 g/dL, p‐value <0.01). When considering the weight difference as a correction between the two surgical groups (because there were many heavier samples in the RMSH group), the blood loss of the RSPH group was also less than that of the RMSH group by 115.95 ± 23.78 mL (p‐value <0.01).ConclusionsOn the basis of our data, the robotic hysterectomy using the da Vinci SP surgical system might be feasible and safe, even if the hysterectomy is complex, and comparable to robotic multisite surgery by the da Vinci Xi system.
