The impact of delayed biliary decompression and anti-microbial therapy in 260 patients with cholangitis-associated septic shock.
Alimentary Pharmacology & Therapeutics 2016 October
BACKGROUND: Cholangitis-associated septic shock carries significant mortality. There is uncertainty regarding the most appropriate time to achieve biliary decompression.
AIM: To determine whether the timing of biliary decompression and anti-microbial therapy affect the survival in cholangitis patients with septic shock.
METHODS: Nested retrospective cohort study of all cholangitis-associated septic shock patients (hypotension requiring vasopressors) from an international, multi-centre database between 1996 and 2011.
RESULTS: Among 260 patients (mean age 69 years, 57% male), overall mortality was 37%. Compared to nonsurvivors (n = 96), survivors (n = 164) had lower mean admission Acute Physiology And Chronic Health Evaluation (APACHE) II (22 vs. 28, P < 0.001) and lower median serum lactate on admission (3.4 vs. 4.6 mmol/L, P < 0.001). Survivors were more likely to receive appropriate anti-microbial therapy earlier (median 2.6 vs. 6.8 h from shock, P < 0.001). Survivors were also more likely to undergo successful biliary decompression earlier (median 8.8 vs. 22 h, P < 0.001). After adjusting for co-variates, APACHE II (odds ratio, OR 1.21 per increment (1.11-1.32), time delay to appropriate anti-microbial therapy [OR 1.15 per hour (1.07-1.25)] and delayed biliary decompression >12 h [OR 3.40 (1.12-10.31)] were all significantly associated with increased mortality (P < 0.04 for all; c-statistic 0.896).
CONCLUSIONS: Patients with septic shock secondary to acute cholangitis have significant mortality. Endoscopic biliary decompression >12 h after the onset of shock and delayed receipt of appropriate anti-microbial therapy were both significantly associated with adverse hospital outcome. This might suggest that early initiation of anti-microbial therapy and urgent biliary decompression (within 12 h) could potentially improve outcomes in this high-risk patient population.
