Background and aims Given the limited data on the safety of endoscopic retrograde cholangiopancreatography (ERCP) in patients with liver cirrhosis, we attempted to evaluate this question using a large national database.
Methods We conducted a matched case – control study using the 2010 National Inpatient Sample database in which four non-cirrhotic controls were matched randomly for every cirrhotic patient from the same 10-year age group. We compared adverse events and safety of inpatient ERCP between patients with (n = 3228) and without liver cirrhosis (controls, n = 12 912).
Results Of the 3228 cirrhotic patients, 2603 (80.6 %) had decompensated and 625 (19.4 %) had compensated disease. Post-procedure bleeding (2.1 % vs. 1.2 %, P < 0.01) was higher in patients compared to controls. On multivariable analysis, decompensated cirrhosis (adjusted odds ratio [aOR], 2.7; 95 % confidence interval [CI], 2.2 – 3.2), compensated cirrhosis (aOR 2.2; 95 %CI 1.2 – 3.9), therapeutic ERCPs (aOR 1.4; 95 % CI 1.2 – 2.1), and biliary sphincterotomy (aOR 1.6; 95 %CI 1.1 – 2.1) were independently associated with increased risk of post-procedure bleeding. Performing ERCPs in large (aOR 0.5; 95 %CI 0.4 – 0.6) and medium (aOR 0.7; 95 %CI 0.6 – 0.9) sized hospitals was associated with a decreased risk of post-procedure bleeding. Biliary sphincterotomy (aOR 1.7; 95 %CI 1.2 – 2.3) and therapeutic ERCPs (aOR 1.1; 95 %CI 1.1 – 1.3) increased the risk of post-ERCP pancreatitis, and pancreatic stent placement was associated with a decreased risk of post-ERCP pancreatitis (aOR 0.8; 95 %CI 0.7 – 0.9).
Conclusions Cirrhosis (both compensated and decompensated), performing therapeutic ERCPs and biliary sphincterotomy increase the risk of post-procedure bleeding. Performing ERCPs in large and medium sized hospitals may improve outcomes.
We have applied a systematic approach for categorizing the reasons for pharmacologic stress. These reasons are heterogeneous, but similar across MPI and echo stress laboratories.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
