Gastrointestinal duplication cysts are traditionally treated by complete surgical resection due to the potential precancerous conditions. Here, we describe an asymptomatic DDC that was successfully treated using endoscopic resection. A submucosal tumor in the descending portion of the duodenum was detected in a 71\u2010year\u2010old female during a regular checkup at our hospital. Upper gastrointestinal endoscopy showed a 10\u2010mm pedunculated submucosal tumor. Endoscopic ultrasonography revealed a 10\u2010mm cystic tumor of low echogenicity that included nodules and debris. Endoscopic resection with hot snare polypectomy was performed for diagnosis and treatment. The postoperative course was uneventful. Histologic examination revealed that the cystic tumor was a DDC. Endoscopic resection is a safe, effective, and minimally invasive alternative to surgical resection for small DDCs with malignant potential.<\/jats:p>","DOI":"10.1002\/deo2.88","type":"journal-article","created":{"date-parts":[[2022,1,9]],"date-time":"2022-01-09T20:18:55Z","timestamp":1641759535000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Endoscopic resection of a duodenal duplication cyst: A case report"],"prefix":"10.1002","volume":"2","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7456-8174","authenticated-orcid":false,"given":"Sayumi","family":"Kurita","sequence":"first","affiliation":[{"name":"Department of Surgery The Jikei University Kashiwa Hospital  Chiba Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazuo","family":"Kitagawa","sequence":"additional","affiliation":[{"name":"Department of Surgery The Jikei University Kashiwa Hospital  Chiba Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naoki","family":"Toya","sequence":"additional","affiliation":[{"name":"Department of Surgery The Jikei University Kashiwa Hospital  Chiba Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masahiko","family":"Kawamura","sequence":"additional","affiliation":[{"name":"Department of Surgery Kawamura Hospital  Shizuoka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Muneo","family":"Kawamura","sequence":"additional","affiliation":[{"name":"Department of Surgery Kawamura Hospital  Shizuoka Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ken","family":"Eto","sequence":"additional","affiliation":[{"name":"Department of Surgery The Jikei University School of Medicine  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,1,9]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jpedsurg.2010.01.010"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1148\/radiographics.13.5.8210590"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1245\/s10434-012-2502-4"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1542\/peds.9.4.449"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1097\/00000658-198808000-00009"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.4132\/KoreanJPathol.2014.48.1.62"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ciresp.2020.02.005"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1007\/s002619900305"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1440-1827.2006.01957.x"},{"key":"e_1_2_10_11_1","first-page":"e32","article-title":"A case series of symptomatic intraluminal duodenal duplication cysts: Presentation, endoscopic therapy, and long\u2010term outcome (with video)","volume":"37","author":"Antaki F","year":"2008","journal-title":"Gastrointest Endosc"}],"container-title":["DEN Open"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/deo2.88","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1002\/deo2.88","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/deo2.88","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,8,24]],"date-time":"2023-08-24T13:16:49Z","timestamp":1692883009000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/deo2.88"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022,1,9]]},"references-count":10,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2022,4]]}},"alternative-id":["10.1002\/deo2.88"],"URL":"https:\/\/doi.org\/10.1002\/deo2.88","archive":["Portico"],"relation":{},"ISSN":["2692-4609","2692-4609"],"issn-type":[{"value":"2692-4609","type":"print"},{"value":"2692-4609","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022,1,9]]},"assertion":[{"value":"2021-08-07","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2021-12-11","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2022-01-09","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"e88"}}
