BACKGROUND: @entity697 ( @entity697 ) requires prompt diagnosis and treatment for optimal management. AIMS: To examine whether a putative "weekend effect" impact outcomes of @entity1 hospitalized for @entity697 . METHODS: We conducted a retrospective study of @entity1 admitted with @entity697 between 2009 and 2012. After excluding those not meeting Tokyo consensus criteria for @entity697 , the cohort was categorized into weekend (Saturday-Sunday) and weekday (Monday-Friday) hospital admission and endoscopic retrograde cholangiography (ERC) groups. Primary outcome was length of stay (LOS); secondary outcomes included ERC performance, organ failure, and mortality. Groups were compared with Chi-square and t tests; predictors of LOS were assessed with linear regression. RESULTS: The cohort consisted of 181 @entity1 (mean age 63.1  years, 62.4  % male). @entity2877 was the most common etiology of @entity697 (29.4  %). Fifty-two @entity1 (28.7  %) were admitted on a weekend and 129 (71.3  %) on a weekday. One hundred forty-one @entity1 (78  %) underwent ERC, of which 120 (85  %) were on a weekday. There were no significant differences in baseline characteristics, LOS, proportion undergoing ERC, time to ERC, organ failure, or mortality between weekend and weekday admission groups. Similarly, there were no significant differences between weekend and weekday ERC groups. In multivariate analyses, international normalized ratio (p  <  0.01) and intensive care unit triage (p  <  0.01) were independent predictors of LOS, whereas weekend admission (p  =  0.23) and weekend ERC (p  =  0.74) were not. CONCLUSIONS: Weekend admission and weekend ERC do not negatively impact outcomes of @entity1 hospitalized with acute @entity255 at a tertiary care center. Further studies, particularly in centers with less weekend resources or staffing, are indicated.
