We present a 23-year-old woman with chronic constipation and excessive straining during defecation who presented at the emergency department in partial gut obstruction with a palpable fecaloma. Manual faecal disimpaction and a sigmoid loop colostomy was initially done. A full thickness rectal biopsy was positive for ganglion cells. Further workup led to the diagnosis of chronic IMC and IMR. The patient underwent laparoscopic modified Duhamel procedure, with an uneventful postoperative course.<\/jats:p>","DOI":"10.1136\/bcr-2020-240209","type":"journal-article","created":{"date-parts":[[2021,6,29]],"date-time":"2021-06-29T12:55:20Z","timestamp":1624971320000},"page":"e240209","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Idiopathic megacolon and megarectum in an adult treated with laparoscopic modified Duhamel procedure"],"prefix":"10.1136","volume":"14","author":[{"given":"Maureen Elvira Padernal","family":"Villanueva","sequence":"first","affiliation":[{"name":"Division of Colorectal Surgery, Department of Surgery, University of the Philippines-Philippine General Hospital, Manila, Philippines"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0887-2498","authenticated-orcid":false,"given":"Marc Paul Jose","family":"Lopez","sequence":"additional","affiliation":[{"name":"Division of Colorectal Surgery, Department of Surgery, University of the Philippines-Philippine General Hospital, Manila, Philippines"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark Augustine S","family":"Onglao","sequence":"additional","affiliation":[{"name":"Division of Colorectal Surgery, Department of Surgery, University of the Philippines-Philippine General Hospital, Manila, Philippines"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,6,29]]},"reference":[{"key":"2025082707175583000_14.6.e240209.1","doi-asserted-by":"crossref","first-page":"399","DOI":"10.1097\/MEG.0b013e3280116cb8","article-title":"Idiopathic megacolon","volume":"19","author":"Autschbach","year":"2007","journal-title":"Eur J Gastroenterol Hepatol"},{"key":"2025082707175583000_14.6.e240209.2","doi-asserted-by":"publisher","DOI":"10.1097\/01.sla.0000157140.69695.d3"},{"key":"2025082707175583000_14.6.e240209.3","doi-asserted-by":"crossref","first-page":"400","DOI":"10.1111\/ped.13559","article-title":"Japanese clinical practice guidelines for allied disorders of Hirschsprung's disease, 2017","volume":"60","author":"Muto","year":"2018","journal-title":"Pediatr Int"},{"key":"2025082707175583000_14.6.e240209.4","doi-asserted-by":"crossref","unstructured":"Infante JM , Alonso MH , Gallardo BP .
