However, the conventional approach to these procedures requires two separate devices, a sphincterotome and a balloon catheter, which can complicate and prolong the procedure. We herein evaluated a novel integrated device combining a sphincterotome and balloon catheter developed to improve the efficiency of ESBD and ESLBD. Methods: This retrospective study compared the clinical outcomes of patients with choledocholithiasis who were treated using conventional sphincterotome and balloon catheters (n = 106) and those who were treated using the integrated device (n = 54). Results: Overall complete stone removal rates (99.1% vs. 100%) and adverse event incidence (12.3% vs. 13.0%) were comparable between the two groups. However, the integrated device significantly reduced total procedure time (40 vs. 27 min, p = 0.01), use of mechanical lithotripter (50.0% vs. 22.2%, p &lt; 0.01), total number of procedures required. Conclusions: Complete stone removal rates and safety were comparable between the two groups. However, the novel integrated device may enhance the efficiency of common bile duct stone removal through ESBD and ESLBD because it eliminates the need to prepare and exchange separate devices.<\/jats:p>","DOI":"10.3390\/jcm14175930","type":"journal-article","created":{"date-parts":[[2025,8,22]],"date-time":"2025-08-22T11:50:31Z","timestamp":1755863431000},"page":"5930","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Efficacy of an Endoscopic Device Integrating a Sphincterotome and a Dilation Balloon Catheter for the Treatment of Choledocholithiasis (with Video)"],"prefix":"10.3390","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0009-0001-9174-2477","authenticated-orcid":false,"given":"Jun-Ichi","family":"Hanatani","sequence":"first","affiliation":[{"name":"Department of Gastroenterology, Nara Medical University, Nara 6348522, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5794-1512","authenticated-orcid":false,"given":"Koh","family":"Kitagawa","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Nara Medical University, Nara 6348522, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shohei","family":"Asada","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Nara Medical University, Nara 6348522, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuki","family":"Motokawa","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Nara Medical University, Nara 6348522, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yui","family":"Osaki","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Nara Medical University, Nara 6348522, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tomihiro","family":"Iwata","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Nara Medical University, Nara 6348522, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2402-574X","authenticated-orcid":false,"given":"Yukihisa","family":"Fujinaga","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Nara Medical University, Nara 6348522, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6295-3283","authenticated-orcid":false,"given":"Norihisa","family":"Nishimura","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Nara Medical University, Nara 6348522, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kosuke","family":"Kaji","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Nara Medical University, Nara 6348522, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3049-3443","authenticated-orcid":false,"given":"Shinya","family":"Sato","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Nara Medical University, Nara 6348522, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3158-5318","authenticated-orcid":false,"given":"Tadashi","family":"Namisaki","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Nara Medical University, Nara 6348522, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6666-5633","authenticated-orcid":false,"given":"Akira","family":"Mitoro","sequence":"additional","affiliation":[{"name":"Division of Endoscopy, Nara Medical University, Nara 6348522, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hitoshi","family":"Yoshiji","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Nara Medical University, Nara 6348522, Japan"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,8,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"765","DOI":"10.1136\/gutjnl-2016-312317","article-title":"Updated guideline on the management of common bile duct stones (CBDS)","volume":"66","author":"Williams","year":"2017","journal-title":"Gut"},{"key":"ref_2","doi-asserted-by":"crossref","unstructured":"Sipahi, S., \u00c7elik, K.E.K., Do\u011fan, N., Mouratidou, T., and Ba\u015f, M.
