Aims ERCP with plastic biliary stent placement is considered as an alternative to surgery in cases of failed removal of common bile duct stones. Current guidelines recommend that it should be removed or replaced within 3–6 months to prevent complications. The primary aim of this study was to identify factors related to the development of stent-related complications such as stent migration, stent occlusion and cholangitis.

Methods This is a single-center retrospective cohort study of patients who underwent ERCP with plastic biliary stent placement secondary to choledocolithiasis from January 1, 2010 to September 30, 2019 at University of the East Ramon Magsaysay Memorial Medical Center, Inc. Statistical comparisons were made using one variable Chi-square test and Student T-test with a level of significance of alpha = 0.05. Correlational analyses were performed using Spearman’s correlation and Multivariate logistic regression analysis.

Results A total of 90 subjects were included in the study (mean age = 52 years). Seventy-seven percent (77%) underwent elective stent evaluation, while 23% had on-demand stent evaluation either due to signs of sepsis or biliary obstruction. The mean interval duration to elective and on-demand stent evaluation were 6.4 months (SD = 10.8, 95% CI 3.9–9.0) and 11.3 months (SD = 11, 95% CI 6.6–16), respectively. Several variables (age, gender, number of retained stone and interval duration to stent evaluation) were analyzed to identify factors related to the development of complications. Stent placement of > 3 months duration was found to be an independent predictor for developing complications (OR 7.9, 95% CI 1.9, 32.7, p-value = 0.01). Spearman´s correlation showed a strong positive correlation between interval duration to stent evaluation and development of stent-related complications (rs = 0.71, p < 0.001).

Conclusions We recommend stent evaluation after 3 months of plastic biliary placement secondary retained common bile duct stone to prevent development of stent-related complications.
