Abstract:
Objective To explore major risk factors for postoperative biliary tract infection associated with endoscopic retrograde cholangiography (ERC), and to evaluate endoscopic nasobiliary drainage (ENBD) for intervening the infection.Methods A total of 512 patients who underwent ERC at the First People's Hospital of Yunnan Province from January 2010 to June 2016 were enrolled and divided into group A and B randomly.Group A underwent ENBD after ERC while group B without.The incidence rates of biliary tract infection in different causes and lesions were compared between the two groups.Results Among the 512 patients, there were 276 cases in group A and 236 cases in group B.The overall postoperative biliary infection rate was 4.30%(22/512).Patients in group A showed a smaller chance of developing postoperative biliary tract infection than that in group B [1.09%(3/276) VS 8.05%(19/236), χ2=15.00, P=0.000].Malignant biliary obstruction was the most common cause (13.46%, 14/104) and the most common site was hepatic portal (13.43%, 9/67).Conclusion ENBD can ensure smooth drainage of bile duct therefore effectively prevent biliary tract infection after ERC, especially for patients with malignant biliary obstruction and hepatic portal lesion.
