Robotic-assisted Cystectomy Verse Open Cystectomy Operatic Outcomes: A Meta-analysis

Objective: Bladder cancer is one of the most lethal urological tumors.The number of robotic assisted radical cystectomy(RARC)is used more widely in spite of the lack of Level I evidence showed any advantages on open radical cystectomy(ORC).But,some systematic reviews with meta-analyses including non-randomized studies and retrospective studies,suggesting an overall great benefit for RARC compared to ORC.We did perform a meta-analysis of randomized controlled trials(RCTs)and prospective trails to evaluate the perioperative safety and efficacy of RARC compared to ORC in patients with bladder cancers.Methods: Searches on Medline/Pubmed,Embase,Cochrane library databases up to 10 th March 2017 were performed.The inclusion criteria for eligible studies were RCTs and prospective trails which compared perioperative outcomes of ORC and RARC for bladder cancers.There are some clinical outcomes which reflexed perioperative and histopathological outcomes of RARC over ORC.Results: At last,there are 8 trails which fit our poppers perfectly.There are some clinical outcomes which contains significant meaning,including the stages of the bladder tumors,the clavien complications >II,the percent of positive lymph nodes,the estimated blood lost,the operation time and the time to regular diet;While there is not significant meaning of some terms,such as he clavien complications I-II,the positive surgery margins,the lengths of admonition time and the numbers of lymph nodes.Conclusions: The results presented evidences for a benefit of the estimated blood lost,time to regular diets,similar perioperative complications and oncological outcomes,while a longer operative time in RARC.It is recorded that RARC was considered as comparable surgical outcomes to ORC.
