ObjectiveTo study short-term (<90 days) morbidity and mortality following radical cystectomy (RC) for bladder cancer and identify modifiable risk factors associated with these.DesignSystematic review.MethodsThe systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. PubMed and EMBASE were searched for relevant papers on 11 June 2019 and rerun on 27 May 2020. Studies reporting complications, reoperations, length of stay and mortality within 90 days were included. Studies were reviewed according to criteria from the Oxford Centre for Evidence-Based Medicine and the quality of evidence was assessed using the Newcastle–Ottawa Scale.ResultsThe search retrieved 1957 articles. Sixty-six articles were included. The quality of evidence was poor to good. Most studies were retrospective, and no randomised clinical trials were identified. Of included studies a median of 6 Martin criteria for reporting complications after surgery were fulfilled. The Clavien-Dindo classification for grading complications was most frequently used. The weighted overall complication rate after RC was 34.9% (range 28.8–68.8) for in-house complications, 39.0% (range 27.3–80.0) for 30-day complications and 58.5% (range 36.1–80.5) for 90-day complications. The most common types of complications reported were gastrointestinal (29.0%) and infectious (26.4%). The weighted mortality rate was 2.4% (range 0.9–4.7) for in-house mortality, 2.1% (0.0–3.7) for 30-day mortality and 4.7% (range 0.0–7.0) for 90-day mortality. Age and comorbidity were identified as the best predictors for complications following RC.ConclusionShort-term morbidity and mortality are high following RC. Reporting of complications is heterogeneous and the quality of evidence is generally low. There is a continuous need for randomised studies to address any intervention that can reduce morbidity and mortality following RC.PROSPERO registration number104937.
To examine surgical outcomes and feasibility of blinding patients and care providers to the surgical technique of radical cystectomy (RC). Patients and MethodsSingle-centre, parallel-group, double-blinded, randomised feasibility study of open RC (ORC) vs robot-assisted RC with intracorporeal urinary diversion (iRARC) in an 'Enhanced Recovery After Surgery' setup. A total of 50 patients aged ≥18 years with bladder cancer planned for RC with an ileal conduit were included. Patients with previous major abdominal/ pelvic surgery, pelvic radiation or anaesthesiological contraindications were excluded. Primary outcomes were proportion of unblinded patients and success of blinding using Bang's Blinding Index. Secondary outcomes included length of stay (LOS), complication rates, blood loss, pain, and opioid consumption. ResultsA total of 26% of the patients were unblinded before discharge. We demonstrated that patients and doctors remained blinded for the allocated treatment, but nurses did not. Blood loss was greater in the ORC group as was operative time in the iRARC group. We found no difference in complication rate, LOS, or use of analgesics. ConclusionsThe present study demonstrates that blinding of surgical technique in RC is possible. The results of secondary outcomes are consistent with the findings of previous unblinded randomised controlled trials. Our study highlights that it is possible to perform a blinded phase III study to explore the optimal surgical technique in RC.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
