Single-port and multiport robot-assisted radical prostatectomy: A meta-analysis

초록

Objective: To compare the perioperative, oncological, and functional outcomes between single-port robot-assisted radical prostatectomy (SP-RARP) and multiport robot-assisted radical prostatectomy (MP-RARP) via a meta-analysis. Methods: For relevant articles, three electronic databases, including PubMed, Scopus, and Web of Science, were searched from their inception until January 15, 2022. A meta-analysis has been reported in line with PRISMA 2020 and AMSTAR Guidelines. The risk ratio and weighted mean difference (MD) were applied for the comparison of dichotomous and continuous variables with 95% confidence intervals (CI). Results: Of the 368 retrieved abstracts, 41 underwent full-text review, and seven studies were included in the final analysis, comprising a total cohort of 1,934 cases of RARP (355 SP-RARP cases and 1,579 MP-RARP cases). Compared to MP-RARP, the SP-RARP group had less postoperative pain score (MD = –0.7, 95% CI –1 to –0.4, P<0.001), morphine milligram equivalents usage (MD = –3.8, 95% CI –7.5 to –0.1, P=0.04), hospital stay (MD = –1, 95% CI –1.8 to –0.1, P=0.019), and urinary catheterization time (MD = –1.1, 95% CI –1.9 to –0.3, P=0.008). However, the SP-RARP group had a longer console time than the MP-RARP group (MD = 5.3, 95% CI 2.6 to 7.9, P<0.001). Conclusions: Our study demonstrated that early results were mostly equivalent with the single-port approach. This technology may help to reduce the hospital stay and postoperative pain for patients undergoing radical prostatectomy compared to MP-RARP, without compromising the functional and early oncological outcomes. © 2023
