Abstract
Subgroup analysis in the non-transplant patients showed that there were trends with documented patient contact (P = 0.111) and insurance type (P = 0.114) with successful stent removal, although neither was statistically significant in liver transplant patients. Conclusion: We demonstrate that 60% of stents were successfully removed and documented patient contact was associated with stent removal at a tertiary safety-net hospital.
