Article intro: single site vs. single site RAMIS

 An interesting article appeared from Lee et al in the Taiwanese Journal of Obstetrics & Gynecology: "First report comparing the two types of single-incision robotic sacrocolpopexy: Single site using the da Vinci Xi or Si system and single port using the da Vinci SP system"

Abstract
Objective
The gold standard procedure for treating patients with apical pelvic organ prolapse (POP) is sacrocolpopexy. However, no report comparing the two types of single-incision robotic sacrocolpopexy, namely, single-site robotic sacrocolpopexy (SS-RSC) and single-port robotic sacrocolpopexy (SP-RSC) exists. Therefore, we compared the safety and effectiveness of SS-RSC and SP-RSC.
Materials and methods
In this study, 48 patients who underwent single-incision RSC, 40 non-consecutive patients who underwent SS-RSC, and 8 consecutive patients who underwent SP-RSC for symptomatic POP quantification stage III–IV and were eligible for the 1-year follow-up (FU) were included. We compared the surgical time and operative outcomes of SS-RSC and SP-RSC. We also compared the data of the initial 8 cases in each group.
Results
The mean patient age was 59.2 ± 11.0 years and 66.1 ± 8.0 years in the SS-RSC (n = 40) and SP-RSC (n = 8) groups, respectively. The mean operative time (OT) and console time were comparable between the SS-RSC and SP-RSC groups (135.3 ± 31.6 min vs 141.8 ± 23.5 min; 94.6 ± 32.2 min vs 89 ± 9.5 min, respectively). The docking time and cervix suturing time were short in the SP-RSC group (P < 0.05). However, in the analysis of the initial 8 cases in each group, all surgical times except the cervix suturing time were shorter in the SP-RSC group (P < 0.05). Three cases had intraoperative bladder injury (two [5.0%] in the SS-RSC and one [12.5%] in the SP-RSC group). Two cases (5.0%) had umbilical incisional hernia in the SS-RSC group. Two cases had vaginal mesh erosion on the posterior vaginal wall, with 1 case in each group. One case (2.5%) experienced a recurrence of POP; an anterior compartment POP-Q stage 2 following SS-RSC at the 4-week FU.
Conclusion
Single-incision RSC, both SS-RSC and SP-RSC, is a feasible and effective surgical option for treating symptomatic apical POP with an aesthetic finish.
