This study aims to examine the value of calretinin immunohistochemistry for more accurately determining the distal and proximal border of the TZ in short segment HSCR. Methods: Specimens of pull-through surgery from 51 patients with short form of HSCR were analyzed on two longitudinal strips using hematoxylin and eosin (H&amp;E) staining and calretinin immunohistochemistry. Results: In all but two patients, the first appearance of calretinin expression was seen on mucosal nerve fibers before the appearance of any ganglion cells, indicating the distal border of the TZ. The maximum distance between the distal border of the TZ and the proximal border of the TZ, defined by ganglion cells in a normal density on H&amp;E stained sections, a strong calretinin expression on mucosal nerve fibers and in &gt;80% of submucosal and myenteric ganglion cells, with no nerve hypertrophy and absence of ganglionitis was 60\u00a0mm. Conclusion: The distal border of the TZ is characterized by calretinin positive intramucosal neurites in nearly all of short form of HSCR and not by calretinin expression on ganglion cells.<\/jats:p>","DOI":"10.1177\/10935266211053973","type":"journal-article","created":{"date-parts":[[2021,12,8]],"date-time":"2021-12-08T03:09:19Z","timestamp":1638932959000},"page":"270-277","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Characterization of the Transition Zone in Short Segment Hirschsprung Disease Using Calretinin Immunostaining"],"prefix":"10.1177","volume":"25","author":[{"given":"Franziska","family":"Righini-Grunder","sequence":"first","affiliation":[{"name":"Division of Pediatric Gastroenterology, Hepatology and Nutrition, CHU Sainte Justine, Montreal, Canada"},{"name":"Division of Pediatric Gastroenterology, Hepatology and Nutrition, Children\u2019s Hospital Lucerne, Lucerne, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Doroth\u00e9e","family":"Bouron-Dal Soglio","sequence":"additional","affiliation":[{"name":"Division of Pediatric Pathology, CHU Sainte Justine, Montreal, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lara","family":"Hart","sequence":"additional","affiliation":[{"name":"Division of Pediatric Gastroenterology, Hepatology and Nutrition, McMaster University, Hamilton, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ann","family":"Aspirot","sequence":"additional","affiliation":[{"name":"Divion of Pediatric Surgery, CHU Sainte Justine, Montreal, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christophe","family":"Faure","sequence":"additional","affiliation":[{"name":"Division of Pediatric Gastroenterology, Hepatology and Nutrition, CHU Sainte Justine, Montreal, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Natacha","family":"Patey","sequence":"additional","affiliation":[{"name":"Division of Pediatric Pathology, CHU Sainte Justine, Montreal, Canada"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2021,12,8]]},"reference":[{"key":"bibr1-10935266211053973","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-319-43268-7_25"},{"key":"bibr2-10935266211053973","doi-asserted-by":"publisher","DOI":"10.1136\/jcp.2004.016030"},{"key":"bibr3-10935266211053973","doi-asserted-by":"publisher","DOI":"10.2350\/08-02-0424.1"},{"key":"bibr4-10935266211053973","doi-asserted-by":"publisher","DOI":"10.1038\/nrgastro.2012.32"},{"key":"bibr5-10935266211053973","doi-asserted-by":"publisher","DOI":"10.1007\/s00418-013-1163-0"},{"issue":"2","key":"bibr6-10935266211053973","first-page":"e367","volume":"25","author":"Anbardar MH","year":"2015","journal-title":"Iran J Pediatr (Persian Ed)"},{"key":"bibr7-10935266211053973","doi-asserted-by":"publisher","DOI":"10.1177\/1093526619892351"},{"key":"bibr8-10935266211053973","doi-asserted-by":"publisher","DOI":"10.1097\/PAS.0000000000000711"},{"key":"bibr9-10935266211053973","doi-asserted-by":"publisher","DOI":"10.1053\/j.sempedsurg.2012.07.003"},{"key":"bibr10-10935266211053973","doi-asserted-by":"publisher","DOI":"10.2350\/13-10-1387-OA.1"},{"key":"bibr11-10935266211053973","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpedsurg.2013.02.026"}],"container-title":["Pediatric and Developmental Pathology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/10935266211053973","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/10935266211053973","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/10935266211053973","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,2]],"date-time":"2026-05-02T04:08:11Z","timestamp":1777694891000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/10935266211053973"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,12,8]]},"references-count":11,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2022,5]]}},"alternative-id":["10.1177\/10935266211053973"],"URL":"https:\/\/doi.org\/10.1177\/10935266211053973","relation":{},"ISSN":["1093-5266","1615-5742"],"issn-type":[{"value":"1093-5266","type":"print"},{"value":"1615-5742","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,12,8]]}}}
