Risk factors for recurrence after surgery for biliary pancreatitis

Objective To investigate the risk factors for recurrence after surgery for biliary pancreatitis.Methods A total of 284 patients with biliary pancreatitis who were treated in The Fourth Hospital of PLA from January 2008 to December 2014 were followed up, and the risk factors for postoperative recurrence were analyzed.The chi-square test was used for categorical data, and the unconditional logistic regression model was used for multivariate analysis.Results The follow-up period ranged from 6 to 27 months (mean 36.4 ± 8.4 months) .Of all patients, 27 experienced recurrence, and the recurrence rate was 9.51%.The univariate analysis showed that postoperative recurrence was associated with a family history of gallstone disease, high-fat diet, sand-like stones, intrahepatic bile duct stones, biliopancreatic duct opening stenosis, and diverticulum around the ampullar region (χ2=8.721, 5.979, 8.641, 15.996, 33.833, and 27.203, all P<0.05) .The multivariate logistic analysis showed that high-fat diet (OR=2.296, P=0.012) , biliopancreatic duct opening stenosis (OR=2.280, P=0.007) , and diverticulum around the ampullar region (OR=2.522, P=0.009) were independent risk factors for recurrence after surgery for biliary pancreatitis.Conclusion Biliary pancreatitis patients with high-fat diet, biliopancreatic duct opening stenosis, or diverticulum around the ampullar region tend to experience recurrence after surgery.Intervention and close follow-up should be performed for these patients to prevent recurrence.
