This natural and evident convergence between EUS and ERCP, which by 2006 we were calling the \u201cEndoscopic ultrasonography retrograde colangiopancreatography (EURCP) concept\u201d, has become a hot topic in the last years, together with the implementation of the therapeutic possibilities of EUS (from EUS-guided necrosectomy to gastro-entero anastomoses) and with the return of ERCP to its original diagnostic purpose thanks to ancillary techniques (extraductal ultrasound (EDUS), intraductal ultrasound (IDUS), cholangiopancreatoscopy with biopsies and probe-based confocal laser endomicroscopy (pCLE)). In this literary review, we retraced the recent history of EUS and ERCP, reported examples of the clinical applicability of the EURCP concept and explored the option of performing the two procedures in only one endoscopic session, with its positive implications for the patient, the endoscopist and the health care system. In the last few years, we also evaluated the possibility of combining EUS and ERCP into a single endoscopic instrument in a single step, but certain obstacles surrounding this approach remain.<\/jats:p>","DOI":"10.3390\/diagnostics13203265","type":"journal-article","created":{"date-parts":[[2023,10,20]],"date-time":"2023-10-20T07:22:32Z","timestamp":1697786552000},"page":"3265","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["The
