Background And Aim:
Endoscopic nasobiliary drainage (ENBD) plays a crucial role in the treatment of acute cholangitis and obstructive jaundice. This research aimed to investigate the clinical characteristics and risk factors associated with nasobiliary drainage (NBD) tube migration.
Methods:
A retrospective single-center study was conducted, including all patients who underwent ERCP and placed an NBD tube between January 2022 and December 2023.
Results:
A total of 1077 patients were included in this study (mean age 59.8 years). Among these, 75 (7.0%) experienced NBD tube migration during their hospital stay. Univariate analysis showed that the maximum width of the bile duct, type of NBD tube, bile duct stricture, placement of a bile stent and/or pancreatic duct stent, and the extracorporeal length of NBD tube were correlated with NBD tube migration (p < 0.05). Multivariate regression analysis indicated that the type of NBD tube (p = 0.01 OR 1.9, 95% CI (1.16-3.13)) and the extracorporeal length of the NBD tube (p < 0.0001 OR 0.96, 95% CI (0.96-0.99)) were independent risk factors for NBD tube migration. Furthermore, it was found that when the extracorporeal length of the NBD tube was greater than 150 cm, the incidence of NBD tube migration was significantly lower than in the group with lengths less than 150 cm (p < 0.001).
Conclusion:
NBD tube migration is not uncommon in clinical practice. The type of NBD tube and the extracorporeal length of the NBD tube were identified as independent risk factors for NBD tube migration. Ensuring that the extracorporeal length of the NBD tube is greater than 150 cm may reduce the incident of NBD tube migration.
