Background Breech presentation delivery approach is a controver-sial issue in obstetrics. How to cope with breech delivery (vaginal or C-section) has been discussed to find the safest in terms of morbid-ity. The aim of this study was to assess the risks of foetal and mater-nal mortality and perinatal morbidity associated with vaginal deliv-ery against elective caesarean in breech presentations, as reported in observational studies. Methods Studies assessing perinatal morbidity and mortality asso-ciated with breech presentations births. Cochrane, Medline, Scopus, Embase, Web of Science, and Cuiden databases were consulted. This protocol was registered in PROSPERO CRD42020197598. Selection criteria were: years between 2010 and 2020, in English language, and full-term gestation (37-42 weeks). The methodological quality of the eligible articles was assessed according to the Newcastle -Ot-tawa scale. Meta-analyses were performed to study each parameter related to neonatal mortality and maternal morbidity. Results The meta-analysis included 94 285 births with breech pre-sentation. The relative risk of perinatal mortality was 5.48 (95% confidence interval (CI) = 2.61-11.51) times higher in the vaginal delivery group, 4.12 (95% CI = 2.46-6.89) for birth trauma and 3.33 (95% CI = 1.95-5.67) for Apgar results. Maternal morbidity showed a relative risk 0.30 (95% CI = 0.13-0.67) times higher in the planned caesarean group. Conclusions An increment in the risk of perinatal mortality, birth trauma, and Apgar lower than 7 was identified in planned vaginal delivery. However, the risk of severe maternal morbidity because of complications of a planned caesarean was slightly higher.
