We report two cases treated with an endoscopic\u2010assisted approach. Case 1 is a 5\u2010year\u2010old girl with Hirschsprung disease who underwent the Duhamel procedure. Persistent constipation led to a contrast enema, confirming septal formation. Transanal endoscopic\u2010assisted division with an endoscopic linear stapler improved symptoms initially. However, constipation and enterocolitis with bleeding recurred 5\u2009months later, requiring redo surgery. Case 2 is a 21\u2010year\u2010old female with a history of Hirschsprung disease, treated with the Duhamel procedure. She had three episodes of severe abdominal pain and enterocolitis in the past month. Colonoscopy revealed a septal formation with proximal intestinal dilatation. Endoscopic\u2010assisted division resulted in complete resolution of symptoms. No complications occurred. Septal formation may cause an obstruction contributing to constipation and enterocolitis. Early recognition and division of the septum are recommended in patients with severe constipation or enterocolitis after the Duhamel procedure.<\/jats:p>","DOI":"10.1111\/ases.70334","type":"journal-article","created":{"date-parts":[[2026,7,3]],"date-time":"2026-07-03T02:50:04Z","timestamp":1783047004000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Endoscopic\u2010Assisted Division of Septal Formation After Duhamel Procedure for Hirschsprung Disease: Two Case Reports"],"prefix":"10.1111","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5423-0296","authenticated-orcid":false,"given":"Shohei","family":"Takami","sequence":"first","affiliation":[{"name":"Department of Pediatric Surgery Japanese Red Cross Medical Center  Tokyo Japan"},{"name":"Department of Pediatric Surgery The University of Tokyo Hospital  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shunji","family":"Nonaka","sequence":"additional","affiliation":[{"name":"Department of Veterinary Anatomy The University of Tokyo  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7827-8147","authenticated-orcid":false,"given":"Hideyuki","family":"Yokokawa","sequence":"additional","affiliation":[{"name":"Department of Pediatric Surgery Japanese Red Cross Medical Center  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ayumi","family":"Kitahara","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology Japanese Red Cross Medical Center  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shinzo","family":"Yamamoto","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology Japanese Red Cross Medical Center  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazuko","family":"Obana","sequence":"additional","affiliation":[{"name":"Department of Pediatric Surgery Japanese Red Cross Medical Center  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshiakira","family":"Kanai","sequence":"additional","affiliation":[{"name":"Department of Veterinary Anatomy The University of Tokyo  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Fujishiro","sequence":"additional","affiliation":[{"name":"Department of Pediatric Surgery The University of Tokyo Hospital  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,7,2]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41572-023-00465-y"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3468(99)90247-6"},{"key":"e_1_2_11_4_1","first-page":"208","article-title":"The Use of Mechanical Suture in the Treatment of Hirschsprung's Disease: Experience of 17 Cases","volume":"109","author":"Spataru R.
