Abstract:
Objective:To study the risk factors of acute gallstone pancreatitis (AGP) caused by impaction of duodenal papilla stones based on ERCP findings to provide evidence on prevention of AGP caused by stone impaction.Methods:The data of 304 patients with duodenal papilla stone impaction who were treated by ERCP at the Integrated Chinese and Western Medicine Hospital of Tianjin University from January 2009 to December 2020 were analyzed retrospectively. There were 177 males and 127 females, with a median age of 65.0 years. These patients were divided into the AGP group ( n=174) and the non-AGP group ( n=130) according to whether they developed acute pancreatitis before hospitalization. The analysis was performed on perioperative data. Multivariate logistic regression analysis was used to detect risk factors of AGP in patients with duodenal papillary stone impaction. Results:Multivariate logistic analysis showed that acute cholangitis ( OR=2.114, 95% CI: 1.279-3.494, P<0.05) and impacted stones ≤5 mm ( OR=1.738, 95% CI: 1.064-2.840, P<0.05) were independent risk factors of duodenal papillary stone impaction complicated with AGP. No perforation and death related to ERCP treatment occurred in both groups. The symptom alleviating time of patients in the AGP versus the non-AGP groups was (2.67±1.19) versus (1.88±0.88) d respectively ( t=-6.321, P<0.001). Conclusion:Among patients with duodenal papilla impacted stones, acute cholangitis and impacted stones ≤5 mm were risk factors of developing AGP, and ERCP should be carried out as early as possible.
