Does the urgency of endoscopic retrograde cholangiopancreatography (ercp)/percutaneous biliary drainage (pbd) impact mortality and disease related complications in ascending cholangitis? (deim-i study)

ASGE guideline on the management of cholangitis

Cholangitis is a GI emergency requiring prompt recognition and treatment. The purpose of this document from the American Society for Gastrointestinal Endoscopy's (ASGE) Standards of Practice Committee is to provide an evidence-based approach for management of cholangitis. This document addresses the modality of drainage (endoscopic vs percutaneous), timing of intervention (<48 hours vs >48 hours), and extent of initial intervention (comprehensive therapy vs decompression alone). Grading of Recommendations, Assessment, Development, and Evaluation methodology was used to formulate recommendations on these topics. The ASGE suggests endoscopic rather than percutaneous drainage and biliary decompression within 48 hours. Additionally, the panel suggests that sphincterotomy and stone removal be combined with drainage rather than decompression alone, unless patients are too unstable to tolerate more extensive endoscopic treatment.

ERCP within 6 or 12 h for acute cholangitis: a propensity score-matched analysis

BACKGROUND

The optimal timing of biliary drainage by endoscopic retrograde cholangiopancreatography (ERCP) for patients with acute cholangitis remains controversial. The aim of our study was to determine if ERCP performed within 6 or 12 h of presentation was associated with improved clinical outcomes.

METHODS

Medical records for all patients with acute cholangitis who underwent ERCP at our institution between 2009 and 2018 were reviewed. Outcomes were compared between those who underwent ERCP within or after 12 h using propensity score framework. Our primary outcome was length of hospitalization. Secondary outcomes included in-hospital mortality, adverse events, ERCP failure, length of ICU stay, organ failure, recurrent cholangitis, and 30-day readmission. In secondary analysis, outcomes for ERCP done within or after 6 h were also compared.

RESULTS

During study period, 487 patients with cholangitis were identified, of whom 147 had ERCP within 12 h of presentation. Using propensity score matching, we selected 145 pairs of patients with similar characteristics. Length of hospitalization was similar between ERCP within or after 12 h (135.9 vs 122.1 h, p 0.094). No difference was noted in mortality, ERCP failure, adverse events, need and length of ICU stay, and recurrent cholangitis. However, 30-day readmission rates were lower when ERCP within 12 h (7.6 vs 15.2, p 0.042). No significant difference was noted in aforementioned outcomes between ERCP performed within or after 6 h.

CONCLUSIONS

ERCP performed within 6 h or 12 h of presentation was not associated with superior clinical outcomes, however, may result in reduced re-hospitalization.

No Association of Timing of Endoscopic Biliary Drainage with Clinical Outcomes in Patients with Non-severe Acute Cholangitis

BACKGROUND

Biliary drainage via endoscopic retrograde cholangiopancreatography (ERCP) is the first-line treatment for acute cholangitis. Despite the established effectiveness of urgent biliary drainage in patients with severe acute cholangitis, the indication of this procedure for non-severe acute cholangitis is controversial.

AIMS

To assess the safety of elective drainage (≥ 12 h of admission) for non-severe acute cholangitis.

METHODS

We retrospectively identified 461 patients with non-severe acute cholangitis who underwent endoscopic biliary drainage. Using linear regression models with adjustment for a variety of potential confounders, we compared elective versus urgent biliary drainage (< 12 h of admission) in terms of clinical outcomes. The primary outcome was the length of stay.

RESULTS

There were 98 and 201 patients who underwent elective and urgent biliary drainage, respectively. The median length of stay was 11 days in both groups (P = 0.52). The timing of ERCP was not associated with length of stay in the multivariable model (P = 0.52). Secondary outcomes including in-hospital mortality and recurrence of cholangitis were not different between the groups.

CONCLUSIONS

Elective biliary drainage was not associated with worse clinical outcomes of non-severe acute cholangitis as compared to urgent drainage. Further investigation is warranted to justify the elective drainage for non-severe cholangitis.

Early biliary drainage is associated with favourable outcomes in critically-ill patients with acute cholangitis

Introduction

Acute cholangitis (AC) is a clinical condition that requires prompt medical management with IV fluids, antibiotics, and biliary drainage (BD). The optimal timing for BD remains unclear.

Aim

To investigate the effect of biliary drainage timing on clinical outcomes in AC.

Material and methods

We conducted a retrospective study of patients with AC admitted to the ICU using the Multiparameter Intelligent Monitoring in Intensive Care III (MIMIC-III) database. Emergency department to BD time, hospital death, length of stay (LOS), and severity scores were extracted from the database. We investigated the effect of BD timing on mortality rates, persistent organ failure, and LOS.

Results

A total of 177 patients were included; 50% were males; median age was 75 years, in-hospital mortality was 9.6%, mean time-to-ERCP was 32 h (range: 0.42–229.6) with 76% meeting the Tokyo Guidelines (TG13) criteria for severe cholangitis, and median Simplified Acute Physiology Score II (SAPS II) was 42 (IQR: 33–51). Using 24 h as a cut-off, patients who underwent BD ≤ 24 h had less persistent organ failure (OR = 0.49; 95% CI: 0.26–0.96, p = 0.040), shorter ICU LOS (3.25 vs. 4.95 days, p = 0.040), shorter hospital LOS (7.71 vs. 13.57 days, p = 0.001), but no difference in either in-hospital mortality (OR = 0.47, 95% CI: 0.17–1.29, p = 0.146) or 28-day mortality (OR = 0.61, 95% CI: 0.24–1.53, p = 0.297).

Conclusions

In critically-ill patients with acute cholangitis, early biliary drainage ≤ 24 h is associated with less persistent organ failure and shorter length of stay but had no effect on patient survival.
