We reviewed the population\u2010based literature to assess international variation of BA incidence and outcomes, and to assess the evidence for seasonal variation in incidence, centralization of Kasai hepatoportoenterostomy, and newborn screening.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods:<\/jats:title><jats:p>We conducted a systematic review (registration number CRD42011001441) of observational or interventional research within MEDLINE, EMBASE, and the Cochrane Database, which reported incidence, prevalence, or outcomes of infants with BA. Population\u2010based studies, defined by inclusion of an entire population or representative sample, were included. Outcomes included overall survival, native liver survival (NLS), and time to Kasai hepatoportoenterostomy. Single\u2010 or multicenter studies were excluded unless those centers captured all potential patients within a jurisdiction. Two independent data extractors reviewed the abstracts and articles.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p>A total of 40 studies were included following review of 3128 references. A wide range of incidence was reported internationally. Ten\u2010year overall survival ranged from 66.7% to 89%. NLS ranged from 20.3% to 75.8% at 1 to 3 years and 24% to 52.8% at 10 years. Earlier age at Kasai was a predictor of improved NLS. Seasonality was reported in 11 studies, and 3 reported an increased incidence during the months of August to March. The evidence for centralization of Kasai to high\u2010volume centers is promising but does not account for all case\u2010mix, provider, or health system factors involved in volume\u2013outcome relations. Stool color card screening resulted in earlier Kasai and improved NLS in Taiwan.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions:<\/jats:title><jats:p>Large, international studies could help fill the gaps in knowledge identified by this review.<\/jats:p><\/jats:sec>","DOI":"10.1097\/mpg.0b013e318282a913","type":"journal-article","created":{"date-parts":[[2012,12,22]],"date-time":"2012-12-22T03:56:07Z","timestamp":1356148567000},"page":"344-354","source":"Crossref","is-referenced-by-count":150,"title":["International Incidence and Outcomes of Biliary Atresia"],"prefix":"10.1002","volume":"56","author":[{"given":"Carolina","family":"Jimenez\u2010Rivera","sequence":"first","affiliation":[{"name":"Division of Gastroenterology, Hepatology and Nutrition Children's Hospital of Eastern Ontario Ottawa ON Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kheira S.","family":"Jolin\u2010Dahel","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, Hepatology and Nutrition Children's Hospital of Eastern Ontario Ottawa ON Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kyle J.","family":"Fortinsky","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, Hepatology and Nutrition Children's Hospital of Eastern Ontario Ottawa ON Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peter","family":"Gozdyra","sequence":"additional","affiliation":[{"name":"Institute for Clinical Evaluative Sciences Toronto ON Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Eric I.","family":"Benchimol","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, Hepatology and Nutrition Children's Hospital of Eastern Ontario Ottawa ON Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2013,4]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/j.1536-4801.2002.tb07807.x"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpeds.2007.05.051"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1136\/adc.2009.159780"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1440-1746.2007.05114.x"},{"key":"e_1_2_8_6_1","first-page":"473","article-title":"Biliary atresia: the Brazilian experience","volume":"86","author":"Carvalho E","year":"2010","journal-title":"J Pediatr"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/hep.24023"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1097\/MPG.0b013e31817d80de"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(99)03492-3"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.290.6465.345"},{"key":"e_1_2_8_11_1","unstructured":"PROSPERO.
