One unique complication of WGC is the perforation of the papilla of Vater by the guidewire.<jats:italic>Subjects and Methods.<\/jats:italic>Of 2032 patients who underwent ERCP at our department between January 2010 and December 2014, we selected 208 patients who underwent WGC for na\u00efve papilla as subjects. A detailed examination of patients in whom a perforation occurred was conducted, and risk factors for perforations were investigated.<jats:italic>Results.<\/jats:italic>The perforation was observed in 7 of 208 patients (3.4%). All patients recovered with conservative treatment without the need for surgery. The perforation rate was significantly higher in the patients with juxtapapillary duodenal diverticula than those without diverticula (12.5% versus 0.6%,<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\"><mml:mi>p<\/mml:mi><mml:mo>&lt;<\/mml:mo><mml:mn fontstyle=\"italic\">0.001<\/mml:mn><\/mml:math>). Cannulation of the bile duct was ultimately achieved in 5 of 7 patients; PSP was performed for 4 of these patients.<jats:italic>Conclusion.<\/jats:italic>Caution must be exercised when dealing with patients who have a juxtapapillary duodenal diverticula because they are at higher risk of perforations. Because these are small perforations made by a wire, most of them heal with conservative treatment. However, perforations can make cannulation difficult, and PSP may be useful for deep cannulation.<\/jats:p>","DOI":"10.1155\/2016\/5825230","type":"journal-article","created":{"date-parts":[[2016,6,5]],"date-time":"2016-06-05T17:01:44Z","timestamp":1465146104000},"page":"1-6","source":"Crossref","is-referenced-by-count":5,"title":["Perforation of the Papilla of Vater in Wire-Guided Cannulation"],"prefix":"10.1155","volume":"2016","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6803-9460","authenticated-orcid":true,"given":"Yuichi","family":"Takano","sequence":"first","affiliation":[{"name":"Division of Gastroenterology, Department of Internal Medicine, Showa University Fujigaoka Hospital, Yokohama, Kanagawa 227-8501, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7773-3072","authenticated-orcid":true,"given":"Masatsugu","family":"Nagahama","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, Department of Internal Medicine, Showa University Fujigaoka Hospital, Yokohama, Kanagawa 227-8501, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5446-7314","authenticated-orcid":true,"given":"Eiichi","family":"Yamamura","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, Department of Internal Medicine, Showa University Fujigaoka Hospital, Yokohama, Kanagawa 227-8501, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naotaka","family":"Maruoka","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, Department of Internal Medicine, Showa University Fujigaoka Hospital, Yokohama, Kanagawa 227-8501, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5957-8286","authenticated-orcid":true,"given":"Hiroshi","family":"Takahashi","sequence":"additional","affiliation":[{"name":"Division of Gastroenterology, Department of Internal Medicine, Showa University Fujigaoka Hospital, Yokohama, Kanagawa 227-8501, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1016\/S0016-5107(04)00363-3"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1572-0241.2007.01378.x"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1055\/s-2007-995566"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1055\/s-2007-995483"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1016\/j.gie.2008.04.064"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1038\/ajg.2009.269"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1016\/j.gie.2009.08.007"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.3109\/00365521.2010.521889"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1111\/j.1443-1661.2012.01372.x"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1016\/j.gie.2011.10.012"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.3748\/wjg.v17.i46.5131"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1055\/s-0030-1256150"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1097\/mcg.0b013e3181aacbd1"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1155\/2012\/821376"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1007\/s10620-012-2274-5"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1001\/archsurg.142.5.448"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.5946\/ce.2012.45.2.177"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1097\/mpa.0b013e31815ac54c"}],"container-title":["Canadian Journal of Gastroenterology and Hepatology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/cjgh\/2016\/5825230.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cjgh\/2016\/5825230.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cjgh\/2016\/5825230.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2016,7,26]],"date-time":"2016-07-26T12:29:33Z","timestamp":1469536173000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/cjgh\/2016\/5825230\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2016]]},"references-count":18,"alternative-id":["5825230","5825230"],"URL":"https:\/\/doi.org\/10.1155\/2016\/5825230","relation":{},"ISSN":["2291-2789","2291-2797"],"issn-type":[{"value":"2291-2789","type":"print"},{"value":"2291-2797","type":"electronic"}],"subject":[],"published":{"date-parts":[[2016]]}}}
