Birth prevalence estimates for major congenital gastrointestinal anomalies are sparse. This paper serves as an in-depth, a priori systematic review protocol for our systematic review identifying and assessing studies reporting population-level birth prevalence estimates for gastrointestinal anomalies.\n                    <jats:italic toggle=\"yes\">Methods<\/jats:italic>\n                    . We will use the Condition, Context, Population framework and will include studies reporting the population-level birth prevalence of gastroschisis, omphalocele, intestinal and esophageal atresia, Hirschsprung\u2019s disease, congenital diaphragmatic hernia, and anorectal malformation in infants. We will assess bias using the Joanna Briggs Institute Critical Appraisal Checklist for Studies Reporting Prevalence Data.\n                    <jats:italic toggle=\"yes\">Results<\/jats:italic>\n                    . Results will be published in a separate paper, and will be stratified by World Bank income classification.\n                    <jats:italic toggle=\"yes\">Conclusion<\/jats:italic>\n                    . Knowledge of the current prevalence of major congenital gastrointestinal anomalies is essential to efficient surgical resource planning. This review will compile existing global estimates of prevalence and incidence of common gastrointestinal congenital anomalies to support policy development.\n                  <\/jats:p>","DOI":"10.1177\/30502225251283177","type":"journal-article","created":{"date-parts":[[2025,3,27]],"date-time":"2025-03-27T07:53:47Z","timestamp":1743062027000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Systematic Review of the Prevalence of Gastrointestinal Congenital Anomalies: A Global and Regional Review Protocol"],"prefix":"10.1177","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9870-8271","authenticated-orcid":false,"given":"Kelsey R.","family":"Landrum","sequence":"first","affiliation":[{"name":"University of North Carolina at Chapel Hill, Gillings School of Global Public Health, Department of Epidemiology, Chapel Hill, NC, USA"},{"name":"University of North Carolina at Chapel Hill, School of Medicine, Department of Surgery, Chapel Hill, NC, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pamela","family":"Espinoza","sequence":"additional","affiliation":[{"name":"Duke University, Duke Global Health Institute, Durham, NC, USA"},{"name":"Duke University School of Medicine, Department of Surgery, Durham, NC, USA"},{"name":"Duke University, Center for Global Surgery and Health Equity, Durham, NC, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Cesia","family":"Cotache-Condor","sequence":"additional","affiliation":[{"name":"Duke University, Center for Global Surgery and Health Equity, Durham, NC, USA"},{"name":"Duke University School of Medicine, Department of Surgery, Durham, NC, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Henry E.","family":"Rice","sequence":"additional","affiliation":[{"name":"Duke University, Duke Global Health Institute, Durham, NC, USA"},{"name":"Duke University School of Medicine, Department of Surgery, Durham, NC, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Brian W.","family":"Pence","sequence":"additional","affiliation":[{"name":"University of North Carolina at Chapel Hill, Gillings School of Global Public Health, Department of Epidemiology, Chapel Hill, NC, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark G.","family":"Shrime","sequence":"additional","affiliation":[{"name":"Mercy Ships, Lindale, TX, USA"},{"name":"Harvard University Medical School, Harvard Program in Global Surgery and Social Change, Boston, MA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chris","family":"Agala","sequence":"additional","affiliation":[{"name":"University of North Carolina at Chapel Hill, School of Medicine, Department of Surgery, Chapel Hill, NC, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jessie K.","family":"Edwards","sequence":"additional","affiliation":[{"name":"University of North Carolina at Chapel Hill, Gillings School of Global Public Health, Department of Epidemiology, Chapel Hill, NC, USA"},{"name":"University of North Carolina at Chapel Hill, Carolina Population Center, Chapel Hill, NC, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emily R.","family":"Smith","sequence":"additional","affiliation":[{"name":"Duke University, Duke Global Health Institute, Durham, NC, USA"},{"name":"Duke University, Center for Global Surgery and Health Equity, Durham, NC, USA"},{"name":"Duke University School of Medicine, Department of Emergency Medicine, Durham, NC, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,3,27]]},"reference":[{"key":"e_1_3_3_2_2","unstructured":"Institute for Health Metrics and Evaluation University of Washington.
