However, EUS\u2010RV has several challenging steps. Herein, we present a method for troubleshooting the EUS\u2010RV using a nasobiliary drainage tube (NBD) in a patient with a large periampullary diverticulum (PAD) and severe gastroptosis. An 80\u2010year\u2010old woman presented with nausea. Contrast\u2010enhanced computed tomography revealed a common bile duct (CBD) stone. Although ERCP was performed twice, the ampulla of Vater (AV) could not be identified due to the large PAD. Therefore, EUS\u2010RV was performed. The CBD was punctured from the descending part of the duodenum. Although a guidewire was advanced through the AV, the PAD hindered guidewire insertion to the anal side of the duodenum. During the switch to duodenoscopy, the guidewire was withdrawn due to gastroptosis. A subsequent attempt to puncture the CBD through the duodenal bulb resulted in guidewire entrapment. To manage the prolonged procedure, a 5\u2010French NBD was temporarily placed in the CBD. An NBD was subsequently inserted into the duodenum via the PAD using esophagogastroduodenoscopy under fluoroscopic guidance after 1 week. After switching to duodenoscopy, SBDC was successful along the NBD that was not withdrawn, and the stone was removed. NBD use in EUS\u2010RV may be effective in difficult cases of guidewire manipulation into the distal duodenum due to PAD and guidewire maintenance due to gastroptosis. Further, NBD is a readily available device, making its use convenient.<\/jats:p>","DOI":"10.1002\/deo2.70237","type":"journal-article","created":{"date-parts":[[2025,11,3]],"date-time":"2025-11-03T04:17:29Z","timestamp":1762143449000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Troubleshooting of Endoscopic Ultrasound\u2010guided Rendezvous Using a Nasobiliary Drainage Tube"],"prefix":"10.1002","volume":"6","author":[{"ORCID":"https:\/\/orcid.org\/0009-0003-1697-0730","authenticated-orcid":false,"given":"Tomohiro","family":"Yamazaki","sequence":"first","affiliation":[{"name":"Department of Gastroenterology St. Luke's International Hospital  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6411-4475","authenticated-orcid":false,"given":"Kenji","family":"Nakamura","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology Tokyo Dental College Ichikawa General Hospital Ichikawa Chiba Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuichiro","family":"Suzuki","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology St. Luke's International Hospital  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuntae","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology St. Luke's International Hospital  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuhei","family":"Okuyama","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology St. Luke's International Hospital  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Koichi","family":"Takagi","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology St. Luke's International Hospital  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katsuyuki","family":"Fukuda","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology St. Luke's International Hospital  Tokyo Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,11,2]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/den.12591"},{"key":"e_1_2_10_3_1","doi-asserted-by":"publisher","DOI":"10.1111\/den.14908"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1097\/00129689-200608000-00002"},{"key":"e_1_2_10_5_1","doi-asserted-by":"publisher","DOI":"10.1067\/mge.2001.118441"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/den.12611"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1055\/s-0043-113444"},{"key":"e_1_2_10_8_1","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0202445"},{"key":"e_1_2_10_9_1","doi-asserted-by":"publisher","DOI":"10.1002\/jhbp.1377"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10620-013-2645-6"},{"key":"e_1_2_10_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.gie.2018.07.030"}],"container-title":["DEN Open"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/deo2.70237","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/full-xml\/10.1002\/deo2.70237","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/deo2.70237","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,9,23]],"date-time":"2026-09-23T13:56:10Z","timestamp":1790171770000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/deo2.70237"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,11,2]]},"references-count":10,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2026,4]]}},"alternative-id":["10.1002\/deo2.70237"],"URL":"https:\/\/doi.org\/10.1002\/deo2.70237","archive":["Portico"],"relation":{},"ISSN":["2692-4609","2692-4609"],"issn-type":[{"value":"2692-4609","type":"print"},{"value":"2692-4609","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,11,2]]},"assertion":[{"value":"2025-02-27","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-10-21","order":2,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication History"}},{"value":"2025-11-02","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}],"article-number":"e70237"}}
