The feasibility of assessing the complete pancreaticobiliary system from the stomach alone has not been studied. We aimed to conceptualize a system-based approach (the railroad approach) for linear pancreaticobiliary EUS (PB-EUS) and evaluate whether the pancreaticobiliary anatomy could be assessed from the stomach alone.<\/jats:p><jats:p>\n          Patients and methods\u2002Three maneuvers were conceptualized and evaluated (the alpha maneuver in the stomach, and sigma and xi maneuvers in the duodenum). The maneuvers were prospectively evaluated in 100 consecutive patients requiring PB-EUS.\u200a<\/jats:p><jats:p>\n          Results\u2002The median procedure time for the three maneuvers was significantly higher than that for the alpha maneuver alone (12 vs. 6 minutes; P\u200a\u2264\u200a0.001). The visualization rate of the hilum and common hepatic duct was significantly higher from the stomach than from the duodenum (100\u200a% vs. 83.5\u200a%; P\u200a\u2264\u200a0.001), while rates for the head of the pancreas (100\u200a% vs 100\u200a%) and uncinate process (100\u200a% vs 100\u200a%) did not differ. The suprapancreatic common bile duct (CBD; 92\u200a% vs 100\u200a%; P\u200a=\u200a0.006), retropancreatic CBD (95\u200a% vs 100\u200a%; P\u200a=\u200a0.06), and pancreatic duct in the head (94\u200a% vs 100\u200a%; P\u200a=\u200a0.03) were not completely visualized from the stomach, because of pancreatic calcification or shadow from the ligaments. The EUS diagnosis made from the stomach and duodenum did not differ after excluding body and tail lesions (pancreatic head neoplasms, 100\u200a% vs 100\u200a%; CBD stone, 100\u200a% vs 84.6\u200a%; pancreatic cysts in the head, 83.3\u200a% vs 83.3\u200a%, respectively).<\/jats:p><jats:p>\n          Conclusions\u2002Adequate anatomical and diagnostic information on the pancreaticobiliary system may be acquired by EUS scanning from the stomach alone and with a shorter procedure time. <\/jats:p>","DOI":"10.1055\/s-0043-118592","type":"journal-article","created":{"date-parts":[[2017,9,21]],"date-time":"2017-09-21T22:34:52Z","timestamp":1506033292000},"source":"Crossref","is-referenced-by-count":1,"title":["Feasibility of a complete pancreatobiliary linear endoscopic ultrasound examination from the stomach"],"prefix":"10.1055","author":[{"given":"Vinay","family":"Dhir","sequence":"additional","affiliation":[{"name":"Baldota Institute of Digestive Sciences, Global Hospitals, Mumbai, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Douglas","family":"Adler","sequence":"additional","affiliation":[{"name":"University of Utah School of Medicine, Salt Lake City, Utah, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nonthalee","family":"Pausawasdi","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, Siriraj Hospital, Bangkok, Thailand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amit","family":"Maydeo","sequence":"additional","affiliation":[{"name":"Baldota Institute of Digestive Sciences, Global Hospitals, Mumbai, India"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Khek","family":"Ho","sequence":"additional","affiliation":[{"name":"National University Health System, Singapore"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"194","published-online":{"date-parts":[[2017,9,21]]},"container-title":["Endoscopy"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/s-0043-118592.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,12,19]],"date-time":"2017-12-19T12:16:28Z","timestamp":1513685788000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/s-0043-118592"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,9,21]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1055\/s-0043-118592","relation":{},"ISSN":["0013-726X","1438-8812"],"issn-type":[{"value":"0013-726X","type":"print"},{"value":"1438-8812","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017,9,21]]}}}
