OBJECTIVE: Suspected sphincter of Oddi dysfunction (SOD) is a well-known risk factor for post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP). The indication of ERCP for suspected SOD patients was very low in Japan compared to other countries. Therefore, the risk of PEP may be different in Japanese SOD patients. The objective of this study was to evaluate the risk of PEP in suspected biliary type SOD in Japan.
METHODS: From December 1996 to January 2017, 72 patients were suspected as having biliary type SOD, by questionnaire, liver function tests, hepatobiliary scintigraphy, abdominal ultrasonography, upper gastrointestinal endoscopy, endoscopic ultrasonography and magnetic resonance cholangiopancreatography. Finally, 60 patients who underwent ERCP were included in this study, and the factors associated with PEP were evaluated.
RESULTS: The overall PEP rate was 23.3% (n = 14). Diagnostic ERCP alone for SOD did not increase the risk of PEP. The correlation of PEP incidence with pancreatic duct guidewire (PGW) technique and endoscopic sphincterotomy (EST) was indicated in univariate and multivariate analysis. Pancreatic stent placement was a risk in univariate analysis but not in multivariate analysis.
CONCLUSIONS: PGW technique and EST for biliary type SOD were important risk factors for PEP. Pancreatic stenting was ineffective for prevention of PEP.
