Abstract
This review article aimed to determine the obstetric and maternal outcomes after B-Lynch compression sutures to control atonic postpartum hemorrhage (PPH). This meta-analysis was performed after registering the protocol in the PROSPERO database with the registration number CRD42022355358. Two independent reviewers systematically searched electronic databases and search engines (PubMed, Cochrane Library, and Google Scholar) to retrieve published articles from inception to July 2022. The obstetric and maternal outcomes after the B-Lynch compression suture were computed using the random-effects model in pooled proportion with a 95% confidence interval (CI). Meta-regression analysis and subgroup analysis were performed to explain any source of possible heterogeneity. Quality assessment of the included studies was done using Joanna Briggs Institute (JBI) tools which are critical appraisal tools for systematic reviews and meta-analyses. This meta-analysis included a total of 30 studies involving 1,270 subjects. The pooled proportion of B-Lynch suture alone was 91% (95% CI = 82-97%). The combined proportion of B-Lynch suture plus another compression suture was 1% (95% CI = 0-3%), and the pooled proportion of B-Lynch suture plus vessel ligation was 3% (95% CI = 1-6%). The pooled proportions of PPH controlled and hysterectomies were 94% (95% CI = 91-97%, I(2) = 65.3%) and 7% (95% CI = 4-10%, I(2) = 72.13%), respectively. Therefore, B-Lynch suture (either alone or in combination with other techniques) is a simple and effective measure to control atonic PPH.
