The double-balloon endoscope provides stable endoscopic maneuvering, even in the small intestine. The aim of this study was to assess the outcomes of balloon-assisted endoscopic submucosal dissection (BAESD) of colonoscopically difficult superficial proximal colon tumors. <\/jats:p><jats:p>\n          Methods\u2002We retrospectively reviewed the records of patients who underwent BAESD of superficial proximal colon tumors where colonoscopic difficulties were encountered, from January 2011 to September 2016. Difficulties were defined as a previous incomplete colonoscopy using a conventional colonoscope or unstable endoscopic maneuverability around the tumor with a conventional colonoscope. A propensity score model was used as a secondary analysis to compare outcomes of the BAESD group with those of a non-BAESD group.\u200a<\/jats:p><jats:p>\n          Results\u2002BAESD was performed on 63 tumors in 63 patients. En bloc resection was achieved for 62 tumors (98\u200a%) and an R0 resection was achieved for 55 tumors (87\u200a%). Propensity score matching analysis created 59 matched pairs from the BAESD and non-BAESD groups. There were no statistically significant differences between the two groups in en bloc resection (100\u200a% vs. 100\u200a%; P\u200a&gt;\u200a0.99), R0 resection (90\u200a% vs. 93\u200a%; P\u200a=\u200a0.74), perforation (0\u200a% vs. 2\u200a%; P\u200a&gt;\u200a0.99) or postoperative bleeding (3\u200a% vs. 0\u200a%; P\u200a=\u200a0.50). <\/jats:p><jats:p>\n          Conclusion\u2002Balloon-assisted endoscopy achieved safe and reliable ESD of colonoscopically difficult superficial proximal colon tumors.<\/jats:p>","DOI":"10.1055\/s-0044-100720","type":"journal-article","created":{"date-parts":[[2018,2,12]],"date-time":"2018-02-12T23:37:24Z","timestamp":1518478644000},"page":"800-808","source":"Crossref","is-referenced-by-count":26,"title":["Balloon-assisted endoscopy facilitates endoscopic submucosal dissection of difficult superficial proximal colon tumors"],"prefix":"10.1055","volume":"50","author":[{"given":"Takeshi","family":"Yamashina","sequence":"additional","affiliation":[{"name":"Department of Medicine, Division of Gastroenterology, Jichi Medical University, Shimotsuke, Japan"},{"name":"Gastroenterology and Hepatology, Osaka Red Cross Hospital, Osaka, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshikazu","family":"Hayashi","sequence":"additional","affiliation":[{"name":"Department of Medicine, Division of Gastroenterology, Jichi Medical University, Shimotsuke, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hirotsugu","family":"Sakamoto","sequence":"additional","affiliation":[{"name":"Department of Medicine, Division of Gastroenterology, Jichi Medical University, Shimotsuke, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomonori","family":"Yano","sequence":"additional","affiliation":[{"name":"Department of Medicine, Division of Gastroenterology, Jichi Medical University, Shimotsuke, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yoshimasa","family":"Miura","sequence":"additional","affiliation":[{"name":"Department of Medicine, Division of Gastroenterology, Jichi Medical University, Shimotsuke, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Satoshi","family":"Shinozaki","sequence":"additional","affiliation":[{"name":"Department of Medicine, Division of Gastroenterology, Jichi Medical University, Shimotsuke, Japan"},{"name":"Shinozaki Medical Clinic, Utsunomiya, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Keijiro","family":"Sunada","sequence":"additional","affiliation":[{"name":"Department of Medicine, Division of Gastroenterology, Jichi Medical University, Shimotsuke, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alan","family":"Kawarai Lefor","sequence":"additional","affiliation":[{"name":"Department of Surgery, Jichi Medical University, Shimotsuke, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hironori","family":"Yamamoto","sequence":"additional","affiliation":[{"name":"Department of Medicine, Division of Gastroenterology, Jichi Medical University, Shimotsuke, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2018,2,12]]},"container-title":["Endoscopy"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/s-0044-100720.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,2,19]],"date-time":"2019-02-19T10:17:30Z","timestamp":1550571450000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/s-0044-100720"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,2,12]]},"references-count":0,"journal-issue":{"issue":"08","published-online":{"date-parts":[[2018,7,26]]},"published-print":{"date-parts":[[2018,8]]}},"URL":"https:\/\/doi.org\/10.1055\/s-0044-100720","relation":{},"ISSN":["0013-726X","1438-8812"],"issn-type":[{"value":"0013-726X","type":"print"},{"value":"1438-8812","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,2,12]]}}}
