Abstract

Purpose: To evaluate the CT severity of post-ERCP pancreatitis (PEP) and determine the association between radiographic and clinical severity.

Methods: There were 1332 patients admitted to the hospital with suspicion for PEP after undergoing ERCP as outpatients over a 10-year period, of whom 84 (6.3%) patients underwent at least one contrast-enhanced CT scan while hospitalized were evaluated. All CT scans were evaluated by two radiologists, and the modified CT severity index (MCTSI) score was calculated. Demographic, clinical, and procedural data as well as clinical severity parameters including systemic inflammatory response syndrome, organ failure, need for ICU, need for intervention, length of hospital stay, and mortality were recorded. Statistical analysis was performed using the χ2 and Student’s t test or ANOVA and logistic regression analysis.

Results: Patients were predominantly females (70%) with a mean age of 46.5 years (range 20–86). The most common indication for ERCP was sphincter of Oddi dysfunction. MCTSI was graded as mild in 45 (53.6%), moderate in 36 (42.8%), and severe in 3 (3.6%) patients. The interobserver agreement was excellent (κ: 0.91, p < 0.0001) for MCTSI. The duration of ERCP (p = 0.005) was the only risk factor for PEP that significantly correlated with the MCTSI score. Increasing MCTSI was significantly associated with hospital length of stay.

Conclusions: PEP is typically a mild disease by radiologic and clinical criteria. Longer duration of ERCP is a risk factor for severe radiologic PEP. Severe radiographic PEP is associated with significantly longer hospital length of stay.
