Infectious Complications of Conventional Laparoscopic <i>vs</i> Robotic Laparoscopic Prostatectomy: A Systematic Literature Review and Meta-Analysis

Abstract

BACKGROUND: Recent studies have shown that using minimally invasive surgical techniques (conventional laparoscopy or robotic) for prostatectomy is associated with lower perioperative complication rates compared with open radical retropubic prostatectomy. However, differences in infectious complications between these minimally invasive approaches are not well characterized. To study this further, we performed a systematic review of the literature and meta-analysis of the infectious complications of prostatectomy, comparing robotic prostatectomy (RP) with conventional laparoscopic prostatectomy (LP). METHODS: estimation and the Cochran Q statistic. pORs were calculated separately based on the indication for prostatectomy. RESULTS: Fifteen studies were included in the final review for the meta-analysis with 14,121 patients undergoing minimally invasive prostatectomy. There was no statistically significant difference in the number of infectious complication events between RP and LP (pOR 0.94; 95% CI 0.50, 1.76). When we performed a stratified analysis, similar results were found with no statistically significant difference in infectious complications comparing RP with LP among patients with prostate cancer (pOR 0.73; 95% CI 0.43, 1.24). We observed that infectious complications were nearly threefold higher with the robotic approach in earlier studies (published between 2007 and 2012, pOR 2.81; 95% CI 1.07, 7.39), but no significant difference was found in later studies (between 2013 and 2018, pOR 0.80, 95% CI 0.40, 1.57). CONCLUSIONS: The rate of infectious complications associated with RP was no different than that associated with conventional LP.
