Laparoscopic radical cystectomy versus open radical cystectomy for the treatment of muscle invasive bladder cancer：a meta-analysis / 中华泌尿外科杂志

ABSTRACT

Objective To systematically evaluate the effectiveness and safety of laparoscopic radical cystectomy (LRC) versus open radical cystectomy (ORC).Methods The databases of Cochrane Library , PubMed, EMbase, SCI, Ovid, CBM, WanFang Data Knowledge Service Platform , VIP Information Chinese Science and China National Knowledge Infrastructure , were searched to collect the randomized controlled trails ( RCTs) and non-RCTs about LRC versus ORC for the treatment of muscle invasive bladder cancer . The retrieval time span was from inception to May 2013.The studies were screened according to the inclusion and exclusion criteria , the data were extracted and the quality was evaluated by 2 reviewers independently.The meta-analysis was conducted using RevMan 5.2.6 software.Results A total of 13 non-RCTs involving 783 patients were included .The meta-analysis showed that comparing with ORC , LRC had lesser intraoperative blood loss [MD =-466.85,95%CI( -603.33, -330.37), P 0.05 ) .Conclusions LRC is safe and feasible for treating muscle invasive bladder cancer when its indications are strictly controlled .However, for the quantity and quality limitation of the involved studies , this conclusion still requires to be further proved by large and high quality studies.
