We aimed to conduct a comprehensive meta-analysis to compare the outcomes of angioembolisation and pelvic packing in patients with pelvic trauma.METHODS: We conducted a systematic search of electronic information sources, including MEDLINE; EMBASE; CINAHL; the CENTRAL; the World Health Organization International Clinical Trials Registry; Clinical Trials.gov; ISRCTN Register, and bibliographic reference lists. The primary outcome was defined as mortality. Combined overall effect sizes were calculated using randomeffects models. Results are reported as the odds ratio(OR) and 95% confidence interval(CI).RESULTS: We identified 3 observational studies reporting a total of 120 patients undergoing angioembolisation(n=60) or pelvic packing(n=60) for pelvic trauma. Reporting of the Injury Severity Score(ISS) was variable, with higher ISS in the pelvic packing group. The risk of bias was low in two studies, and moderate in one. The pooled analysis demonstrated that angioembolisation did not significantly reduce mortality in patients with pelvic trauma compared to surgery(OR=1.99; 95% CI= 0.83–4.78, P=0.12). There was mild between-study heterogeneity(I^2=0%, P=0.65).CONCLUSION: Our analysis found no significant difference in mortality between angioembolisation and pelvic packing in patients with traumatic pelvic haemorrhage. The current level of evidence in this context is very limited and insufficient to support the superiority of a treatment modality. Future research is required.展开更多
