National trends and outcomes in timing of ERCP in patients with cholangitis

National analysis of outcomes in timing of cholecystectomy for acute cholangitis

BACKGROUND

The present study aimed to compare outcomes between cholecystectomy on index versus delayed admission for acute cholangitis.

METHODS

The 2011-2020 Nationwide Readmissions Database was used to identify adult patients admitted for acute cholangitis who underwent cholecystectomy. Study cohorts were defined based on timing of surgery. Multivariable regressions and Royston-Parmar time-adjusted analysis were used to evaluate the association of cholecystectomy timing and outcomes.

RESULTS

Of 65,753 patients, 82.0 ​% received surgery on Index and 18.0 ​% on Delayed admissions. Following adjustment, Delayed operation was associated with significantly increased odds of mortality (AOR 1.67 [95 ​% CI 1.10-2.54]), complications (1.25 [1.13-1.40]), repair of bile duct injury (1.66 [1.15-2.41]), conversion to open (1.69 [1.48-1.93]), and 30-day readmission (3.52 [3.21-3.86]). The Delayed cohort experienced a +$14,200 increment in hospitalization costs relative to Index.

CONCLUSIONS

Delayed cholecystectomy for acute cholangitis is significantly associated with adverse postoperative outcomes, suggesting that index cholecystectomy may be safe to perform.

Outcomes and predictors of delayed endoscopic biliary drainage for severe acute cholangitis due to choledocholithiasis in an intensive care unit

BACKGROUND

Acute cholangitis (AC) is an infection of the biliary tract secondary to biliary obstruction requiring biliary drainage through endoscopic retrograde cholangiopancreatography. This study aims to compare the outcome between the early and delayed ERCP in patients with severe AC.

METHODS

Patient with severe AC due to choledocholithiasis admitted to intensive care unit were included. Early ERCP was defined was as ERCP performed within 24 h following hospital admission. Propensity-score matching was used to reduce the imbalance between groups. The primary outcome was 30-day mortality. Secondary outcomes included length of hospital and ICU stay, onset or persistent organ failure.

RESULTS

The delayed ERCP group had a higher mortality rate at 30 days (45,5 versus 13%, <0.001) and at 1 year (59,7% versus 15,6%, p <0.001). Delayed ERCP had also a higher rate of respiratory adverse events (54,5 versus 27,8%, p = 0,002), longer ICU (7.41 versus 4.61, p = 0,004) and hospital (11,88 versus 9,22, p = 0,042) length of stay. Predictors of delayed ERCP were cardiac arrythmias, liver disease, creatinine value and white blood cell count at baseline.

CONCLUSIONS

Delays in ERCP for patients with severe AC appear to be associated with higher mortality rate and prolonged ICU and hospital stays.

Ten-Year Trends of Persistent Mortality With Gallstone Disease: A Retrospective Cohort Study in New Jersey

BACKGROUND AND AIMS

Recent trends in mortality with gallstone disease remain scarce in the United States. Yet multiple changes in clinical management, such as rates of endoscopy, cholecystectomy, and cholecystostomy, and insurance access at the state level, may have occurred. Thus, we evaluated recent secular trends of mortality with gallstone disease in New Jersey.

METHODS

We performed a retrospective, cohort study of mortality from 2009 to 2018 using the National Center for Health Statistics, Restricted Mortality Files. The primary outcome was any death with an International Classifications of Disease, 10th Revision, Clinical Modification diagnosis code of gallstone disease in New Jersey. Simple linear regression was used to model trends of incidence of death.

RESULTS

1580 deaths with diagnosed gallstone disease (dGD) occurred from 2009 to 2018. The annual trend of incidence of death was flat over 10 years. The incidence of death with dGD relative to all death changed only from 0.21% to 0.20% over 10 years. These findings were consistent also in 18 of 20 subgroup combinations, although the trend of death with dGD in Latinos 65 years or older increased [slope estimate 0.93, 95% confidence limit 0.42-1.43, P = .003].

CONCLUSION

The rate of death with dGD showed little change over the recent 10 years in New Jersey. This needs to be reproduced in other states and nationally. A closer examination of the changes in clinical care and insurance access is needed to help understand why they did not result in a positive change in this avoidable cause of death.

Association of Timing of Biliary Drainage with Clinical Outcomes in Severe Acute Cholangitis: A Retrospective Cohort Study

Purpose

The guidelines recommend urgent biliary drainage (BD) for severe acute cholangitis, without a clear definition of “urgent”. To explore the optimal time, we identified the impact of timing of BD on clinical outcomes in severe acute cholangitis.

Patients and Methods

A retrospective study of patients with severe acute cholangitis was conducted based on the Multiparameter Intelligent Monitoring in Intensive Care III (MIMIC-III) database. Multivariable regressions were used to identified the effect of timing of BD on in-hospital mortality, 30-day mortality, and the length of stay (LOS) in hospital and the intensive care unit (ICU) with adjustment for confounding factors.

Results

A total of 106 severe acute cholangitis patients underwent BD with a median time of 14.14 hours (IQR: 7.60–32.59). Among them, 67.9% were performed within 24 hours and 80.2% within 48 hours. Median length of stay was 2.65 days (IQR: 1.70–5.12) in the ICU and 7.54 days (IQR: 4.49–17.17) in hospital. The in-hospital and 30-day mortality rates were 13.2% and 14.2%, respectively. On multivariate analysis, every 1-day delay of BD increased 1.49 days of stay in hospital (P<0.0001). Delayed BD (>48 hours) was linked with 5.56 days longer ICU LOS (P = 0.0096), while urgent BD (<24 hours) did not significantly shorten the ICU stay (P = 0.0997). No significant increase was observed on in-hospital mortality (OR = 1.03; 95% CI 0.93–1.13) nor 30-day mortality (OR=1.01; 95% CI 0.87–1.14) with BD delay in this population.

Conclusion

In severe acute cholangitis patients, delay in BD increased in-hospital LOS. BD after 48 hours was associated with longer ICU LOS. Yet, BD within 24 hours did not significantly reduce the mortality nor shortened the ICU LOS.
