This study aimed to determine the outcomes of ESD with double clip and rubber band traction (DCT-ESD) of L-PAO including a majority of type 3.<\/jats:p><jats:p>\n          Patients and methods\u2002We reviewed retrospectively all consecutive DCT-ESD of L-PAO performed in 3 French centers. Each lesion was described according to Toyonaga\u2019s classification and type 0 lesions were excluded. The primary outcome was en bloc and R0 resection rates for L-PAO. Morbidity and salvage surgery were recorded.<\/jats:p><jats:p>\n          Results\u2002A total of 32 patients underwent DCT-ESD; 22 lesions (68.8\u200a%) were type 3, including 11 with previous appendectomy (34.4\u200a%). Median lesion size was 35\u200amm range (10\u2013110\u200amm) and median duration of resection was 47\u200amin range (10\u2013230\u200amin). We achieved 100\u200a% of En bloc resection exclusively with DCT-ESD and 90.6\u200a% of histological R0 resection rate. Per-procedure, 11 perforations occurred and were all immediately closed with clips. Overall, 3 patients (10.7\u200a%) underwent surgery without stoma (2 complications related and 1 incomplete resection). No death occurred.<\/jats:p><jats:p>\n          Conclusion\u2002ESD of lesions deeply invading appendiceal orifice is feasible with the help of a traction system. Technical success by endoscopy avoiding surgery was achieved in 90.6\u200a% of cases. <\/jats:p>","DOI":"10.1055\/a-1072-4830","type":"journal-article","created":{"date-parts":[[2020,4,3]],"date-time":"2020-04-03T09:37:17Z","timestamp":1585906637000},"page":"E388-E395","source":"Crossref","is-referenced-by-count":39,"title":["ESD with double clips and rubber band traction of neoplastic lesions developed in the appendiceal orifice is effective and safe"],"prefix":"10.1055","volume":"08","author":[{"given":"Borathchakra","family":"Oung","sequence":"additional","affiliation":[{"name":"Department of Endoscopy and Gastroenterology, Pavillon L, Edouard Herriot Hospital, Hospices Civils de Lyon, Lyon, France"},{"name":"Cambodian Association of Gastrointestinal Endoscopy (CAGE), Cambodia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J\u00e9r\u00f4me","family":"Rivory","sequence":"additional","affiliation":[{"name":"Department of Endoscopy and Gastroenterology, Pavillon L, Edouard Herriot Hospital, Hospices Civils de Lyon, Lyon, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Edouard","family":"Chabrun","sequence":"additional","affiliation":[{"name":"Department of Endoscopy and Gastroenterology, Bordeaux University Hospital, Bordeaux, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Romain","family":"Legros","sequence":"additional","affiliation":[{"name":"Department of Endoscopy and Gastroenterology, Dupuytren University Hospital, Limoges, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julien","family":"Faller","sequence":"additional","affiliation":[{"name":"Department of Endoscopy and Gastroenterology, Pavillon L, Edouard Herriot Hospital, Hospices Civils de Lyon, Lyon, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Florence","family":"L\u00e9ger-Nguyen","sequence":"additional","affiliation":[{"name":"Gastroenterology and Endoscopy, Val d\u2019ouest private clinic, Ecully, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Florian","family":"Rostain","sequence":"additional","affiliation":[{"name":"Department of Endoscopy and Gastroenterology, Pavillon L, Edouard Herriot Hospital, Hospices Civils de Lyon, Lyon, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Charles-Eric","family":"Ber","sequence":"additional","affiliation":[{"name":"Department of Anesthesiology, Pavillon L, Edouard Herriot Hospital, Hospices Civils de Lyon, Lyon, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Val\u00e9rie","family":"Hervieu","sequence":"additional","affiliation":[{"name":"Department of Pathology, Pavillon L, Edouard Herriot Hospital, Hospices Civils de Lyon, Lyon, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean-Christophe","family":"Saurin","sequence":"additional","affiliation":[{"name":"Department of Endoscopy and Gastroenterology, Pavillon L, Edouard Herriot Hospital, Hospices Civils de Lyon, Lyon, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thierry","family":"Ponchon","sequence":"additional","affiliation":[{"name":"Department of Endoscopy and Gastroenterology, Pavillon L, Edouard Herriot Hospital, Hospices Civils de Lyon, Lyon, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J\u00e9r\u00e9mie","family":"Jacques","sequence":"additional","affiliation":[{"name":"Department of Endoscopy and Gastroenterology, Dupuytren University Hospital, Limoges, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mathieu","family":"Pioche","sequence":"additional","affiliation":[{"name":"Department of Endoscopy and Gastroenterology, Pavillon L, Edouard Herriot Hospital, Hospices Civils de Lyon, Lyon, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2020,2,21]]},"container-title":["Endoscopy International Open"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/a-1072-4830.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,4,3]],"date-time":"2020-04-03T09:37:41Z","timestamp":1585906661000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/a-1072-4830"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2020,2,21]]},"references-count":0,"journal-issue":{"issue":"03","published-online":{"date-parts":[[2020,2,21]]},"published-print":{"date-parts":[[2020,3]]}},"URL":"https:\/\/doi.org\/10.1055\/a-1072-4830","relation":{},"ISSN":["2364-3722","2196-9736"],"issn-type":[{"value":"2364-3722","type":"print"},{"value":"2196-9736","type":"electronic"}],"subject":[],"published":{"date-parts":[[2020,2,21]]}}}
