Postoperative complications were not significantly different between EA patients with CES and those without CES but with anastomotic stricture. All CES patients underwent balloon dilatation as initial treatment. Eight of nine patients (89%) were successfully treated by dilatation only, and one patient underwent surgical resection. The median number of balloon dilatations for CES was five (2\u201317), which was higher than that for anastomotic stricture in patients without CES (<jats:italic>p<\/jats:italic>\u2009=\u20090.012). Esophageal perforation occurred in five patients with CES (5\/9, 56%) after dilatation, but all perforations were successfully managed conservatively with an uneventful post-dilatation course.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Conclusions<\/jats:title>\n                <jats:p>Twenty-three percent of patients with EA had CES. Although balloon dilatation for EA-associated CES required multiple treatments and carried a risk of perforation, balloon dilatation showed an 89% success rate and all perforations could be managed conservatively.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1007\/s00383-024-05652-w","type":"journal-article","created":{"date-parts":[[2024,3,22]],"date-time":"2024-03-22T08:39:20Z","timestamp":1711096760000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Balloon dilatation for congenital esophageal stenosis associated with esophageal atresia"],"prefix":"10.1007","volume":"40","author":[{"given":"Koichi","family":"Deguchi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masafumi","family":"Kamiyama","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazunori","family":"Masahata","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Motonari","family":"Nomura","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Miho","family":"Watanabe","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takehisa","family":"Ueno","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuko","family":"Tazuke","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroomi","family":"Okuyama","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2024,3,22]]},"reference":[{"key":"5652_CR1","first-page":"33","volume":"6","author":"E Pritchard","year":"1913","unstructured":"Pritchard E, Drew D (1913) Congenital \u0153sophageal stenosis.
