The aim of the present analysis was to evaluate the clinical and economic impact of the use of single-operator intraductal cholangioscopy (IDC), which allows for direct visualization of the bile duct, as an alternative to ERCP for the treatment of difficult bile duct stones and the diagnosis of bile duct strictures.<\/jats:p><jats:p>\n          Patients and methods\u2002The clinical and economic consequences of single-operator IDC use were evaluated using two decision-tree models, one for management of difficult-to-remove stones and one for stricture diagnosis. A hospital perspective was adopted. Data to populate the models were derived from two Belgian hospitals that specialize in endoscopic procedures of the bile duct. Overall, the examined population consisted of 62 patients with difficult stones and 49 patients with indeterminate strictures.<\/jats:p><jats:p>\n          Results\u2002In the model for difficult stone management, the use of IDC determined a decrease in the number of procedures (\u2013\u200a27\u200a% relative reduction) and costs (\u2013\u200a\u20ac73\u2005000;\u200a\u2013\u200a11\u200a% relative reduction) when compared with ERCP. In the model for stricture diagnosis, the use of IDC determined a decrease in the number of procedures (\u2013\u200a31\u200a% relative reduction) and costs (\u2013\u200a\u20ac13\u2005000;\u200a\u2013\u200a5\u200a% relative variation) when compared with ERCP.<\/jats:p><jats:p>\n          Conclusions The single-operator IDC system performed better than ERCP for the treatment of difficult bile duct stones and the diagnosis of bile duct strictures, and reduced the overall expenditure in hospitals in Belgium.<\/jats:p>","DOI":"10.1055\/s-0043-121268","type":"journal-article","created":{"date-parts":[[2017,11,24]],"date-time":"2017-11-24T23:39:38Z","timestamp":1511566778000},"page":"109-118","source":"Crossref","is-referenced-by-count":78,"title":["The economic impact of using single-operator cholangioscopy for the treatment of difficult bile duct stones and diagnosis of indeterminate bile duct strictures"],"prefix":"10.1055","volume":"50","author":[{"given":"Pierre","family":"Deprez","sequence":"additional","affiliation":[{"name":"Department of Hepatogastroenterology, Cliniques universitaires Saint-Luc, Universit\u00e9 Catholique de Louvain, Brussels, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rodrigo","family":"Garces Duran","sequence":"additional","affiliation":[{"name":"Department of Hepatogastroenterology, Cliniques universitaires Saint-Luc, Universit\u00e9 Catholique de Louvain, Brussels, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tom","family":"Moreels","sequence":"additional","affiliation":[{"name":"Department of Hepatogastroenterology, Cliniques universitaires Saint-Luc, Universit\u00e9 Catholique de Louvain, Brussels, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gianluca","family":"Furneri","sequence":"additional","affiliation":[{"name":"Health Economics and Outcome Research Department, EBMA Consulting, Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Federica","family":"Demma","sequence":"additional","affiliation":[{"name":"Health Economics and Outcome Research Department, EBMA Consulting, Milan, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Len","family":"Verbeke","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology and Hepatology, University Hospital Gasthuisberg, Leuven, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Schalk","family":"Van der Merwe","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology and Hepatology, University Hospital Gasthuisberg, Leuven, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wim","family":"Laleman","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology and Hepatology, University Hospital Gasthuisberg, Leuven, Belgium"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2017,11,24]]},"container-title":["Endoscopy"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/s-0043-121268.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2018,1,29]],"date-time":"2018-01-29T23:30:54Z","timestamp":1517268654000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/s-0043-121268"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,11,24]]},"references-count":0,"journal-issue":{"issue":"02","published-online":{"date-parts":[[2018,1,29]]},"published-print":{"date-parts":[[2018,2]]}},"URL":"https:\/\/doi.org\/10.1055\/s-0043-121268","relation":{},"ISSN":["0013-726X","1438-8812"],"issn-type":[{"value":"0013-726X","type":"print"},{"value":"1438-8812","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017,11,24]]}}}
