A total of 68 ERCP were performed with a 4.4% of procedure\u2010related adverse events. Mortality related to cholangitis secondary to endoscopic procedures was 12%. After median follow\u2010up of 70.3\u00a0months from stents removal, NABS resolution was obtained in 12 out of 24 (50%) patients. Only one case of late NABS recurrence was observed which was successfully retreated endoscopically.

However, patients who respond to endoscopic treatment maintain the response over time. Prompt treatment of acute cholangitis due to stents occlusion is advised in these patients to avoid high mortality rates.<\/jats:p><\/jats:sec>","DOI":"10.1111\/den.13879","type":"journal-article","created":{"date-parts":[[2020,10,20]],"date-time":"2020-10-20T17:13:44Z","timestamp":1603214024000},"page":"849-857","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Endoscopic management of non\u2010anastomotic biliary strictures following liver transplantation: Long\u2010term results from a single\u2010center experience"],"prefix":"10.1111","volume":"33","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7928-3757","authenticated-orcid":false,"given":"Federico","family":"Barbaro","sequence":"first","affiliation":[{"name":"Digestive Endoscopy Unit Policlinico Universitario A.
