Objective:To study the influencing factors of postoperative complications in patients with malignant biliary obstruction treated by endoscopic radiofrequency ablation(RFA).Methods:Data of patients with malignant biliary obstruction who underwent endoscopic RFA at the Department of Gastroenterology, Affiliated Hangzhou First People's Hospital, Zhejiang University School of Medicine from January 2010 to June 2021 were retrospectively analyzed. There were 62 males and 48 females, with age (74.1±11.1) years. Based on occurrence of postoperative complications, these patients were divided into the complication group ( n=18) and the control group ( n=92). Univariate and multivariate logistic regression analysis were used to analysis the influencing factors of complications. Results:RFA was successfully performed in 110 patients with malignant biliary obstruction, and the technical success rate was 100.0% (110/110). Postoperative complications occurred in 18 patients (16.4%), including 12 patients with of biliary tract infection (8 patients with acute cholangitis, 4 patients with acute cholecystitis) and 6 patients with acute pancreatitis. All these patients responded well to treatment. The proportion of patients who developed complications having associated diabetes, bile duct stenosis length >2.5 cm, fractional RFA for bile duct stenosis, and single stent drainage were significantly higher than those in the control group (all P<0.05). Multivariate logistic regression analysis showed that the risk of complications after endoscopic RFA was significantly increased in patients with diabetes ( OR=6.967, 95% CI: 1.256-38.658) and fractional RFA of bile duct stenosis ( OR=8.297, 95% CI: 1.526-45.122), while the risk of complications after multiple stents drainage ( OR=0.037, 95% CI: 0.008-0.169) was significantly decreased (all P<0.05). Conclusion:Diabetes and fractional RFA of bile duct stenosis were risk factors for complications after endoscopic RFA of malignant biliary obstruction. Multiple stents drainage was a protective factor. Better clinical attention should be paid to the patients with high risk factors.
