Current gold standard diagnostics for BA include intraoperative cholangiography and liver biopsy, both invasive procedures with significant complication risks. Matrix metalloproteinase-7 (MMP-7) has emerged as a highly accurate noninvasive diagnostic biomarker for BA. This study therefore aimed to evaluate the diagnostic utility of serum MMP-7 for BA detection.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We performed a comprehensive search of English-language databases (PubMed, Web of Science, ScienceDirect) with literature from the inception of these databases through 30 November 2024. Study quality was assessed using the QUADAS-2 tool. Sensitivity, specificity, positive\/negative likelihood ratios (PLR\/NLR), and area under the receiver operating characteristic curve (AUC-ROC) were calculated using Meta-DiSc 1.4 and STATA 18.0.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      This systematic review and meta-analysis included 13 articles (17 studies) comprising 2,836 serum samples from pediatric subjects. Binary classification model analysis showed pooled sensitivity of 0.93 (95% CI: 0.92\u20130.94) and specificity of 0.85 (95% CI: 0.83\u20130.87) for MMP-7. Positive likelihood ratio (PLR) was 7.68 (95%CI: 5.04\u201311.72), the negative likelihood ratio (NLR) was 0.08 (95%CI: 0.05\u20130.14), and the diagnosis odds ratio (DOR) was 104.34 (95%CI: 55.97\u2013194.51). AUC was 0.9628. Meta-regression analysis identified publication year as a significant heterogeneity source (p = 0.007). Sensitivity analysis confirmed the robust diagnostic stability of MMP-7 for BA. Significant heterogeneity was observed across studies (I\n                      <jats:sup>2<\/jats:sup>\n                      = 78.6%). Subgroup analysis by publication year showed that heterogeneity primarily originated from studies published in or after 2023.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Serum MMP-7 represents a convenient, accurate, and reliable noninvasive biomarker for enhancing BA diagnostic efficiency.
