Late deaths occurred in 46.2% of patients: 13.3% LC vs. 61.9% conservative (P<0.001). Three years after PC, the estimated survival was 75% LC vs. 38% conservative (P=0.014). High-grade comorbidities and severity of ACC were positive predictors of all-cause mortality (P=0.004 and P=0.027), whereas LC was a negative predictor (P=0.003).</p><p><strong>Conclusions: </strong>Recurrent biliary events were common following PC for ACC. Interval LC was associated with lower rates of readmissions and all-cause late mortality.</p>","PeriodicalId":7978,"journal":{"name":"Annals of Gastroenterology","volume":"37 6","pages":"718-725"},"PeriodicalIF":2.1,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11574151/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142680640","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
