For successful endoscopic management of bile duct stones, there are multiple hurdles: Intubation to the afferent limb, biliary cannulation, ampullary intervention and stone extraction. The major advancement in this area is the development of dedicated device\u2010assisted endoscopes for endoscopic retrograde cholangiopancreatography (<jats:styled-content style=\"fixed-case\">ERCP<\/jats:styled-content>). In patients with Billroth <jats:styled-content style=\"fixed-case\">II<\/jats:styled-content> reconstruction, a high technical success rate is reported using a duodenoscope but can be complicated by a potentially high perforation rate. In patients with Roux\u2010en\u2010Y reconstruction, device\u2010assisted <jats:styled-content style=\"fixed-case\">ERCP<\/jats:styled-content> shows high technical success and low adverse event rates. Meanwhile, endoscopic papillary large balloon dilation enables safe and effective stone extraction with less use of endoscopic mechanical lithotripsy in patients with a dilated distal bile duct, but intraductal lithotripsy is sometimes necessary for management of very large bile duct stones. In cases with difficult stones, alternative approaches such as laparoscopy\u2010assisted <jats:styled-content style=\"fixed-case\">ERCP<\/jats:styled-content> and endoscopic ultrasound (<jats:styled-content style=\"fixed-case\">EUS<\/jats:styled-content>)\u2010guided intervention are increasingly reported with preliminary but promising results. However, comparative studies are still lacking in this area and prospective randomized controlled trials are warranted in terms of safety, efficacy and cost\u2010effectiveness.<\/jats:p>","DOI":"10.1111\/den.13022","type":"journal-article","created":{"date-parts":[[2018,4,16]],"date-time":"2018-04-16T10:52:31Z","timestamp":1523875951000},"page":"67-74","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":60,"title":["Endoscopic management of bile duct stones in patients with surgically altered anatomy"],"prefix":"10.1111","volume":"30","author":[{"given":"Yousuke","family":"Nakai","sequence":"first","affiliation":[{"name":"Department of Gastroenterology Graduate School of Medicine The University of Tokyo Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hirofumi","family":"Kogure","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology Graduate School of Medicine The University of Tokyo Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Atsuo","family":"Yamada","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology Graduate School of Medicine The University of Tokyo Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroyuki","family":"Isayama","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology Graduate School of Medicine The University of Tokyo Tokyo Japan"},{"name":"Department of Gastroenterology Graduate School of Medicine Juntendo University Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazuhiko","family":"Koike","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology Graduate School of Medicine The University of Tokyo Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2018,4,16]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1067\/mge.2001.120169"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1067\/mge.2002.120385"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1055\/s-0042-108641"},{"key":"e_1_2_11_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/den.12818"},{"issue":"2","key":"e_1_2_11_6_1","doi-asserted-by":"crossref","first-page":"122","DOI":"10.1111\/den.12274","article-title":"Endoscopic bile duct and\/or pancreatic duct cannulation technique for patients with surgically altered gastrointestinal anatomy","volume":"26","author":"Okabe Y","year":"2014","journal-title":"Dig.
