Background |
Management of anastomotic biliary strictures after liver transplantation deserves optimization.
Objective |
To evaluate placement and removal of partially covered self-expandable metal stents (PCSEMSs) in this setting.
Design |
Prospective, multicenter, uncontrolled study.
Setting |
Three French academic hospitals with liver transplantation units and tertiary referral endoscopy centers.
Patients |
Twenty-two patients (18 men, 4 women, aged 49.7 ± 12 years) with anastomotic biliary stricture. Seventeen (77.3%) presented stricture recurrence after plastic stenting.
Interventions |
PCSEMSs were placed across the stricture for 2 months and then removed. Patients were followed by clinical examination and liver function tests 1, 3, 6, 9, and 12 months after PCSEMS removal.
Main Outcome Measurement |
The ability to remove PCSEMS.
Results |
PCSEMS placement was successful in all patients, after sphincterotomy in 21 patients. Stent-related complications included minor pancreatitis (3 patients), transient pain (1 patient), and cholangitis (1 patient). Stent removal was achieved in all patients but 2 whose stents had migrated distally. Partial stent dislocation was noted in 5 patients (upward in 4, downward in 1). Complications associated with stent removal were minor, including self-contained hemorrhage (1 patient) and fever (1 patient). The stricture persisted at the end of treatment in 3 patients (13.6%), all of whom had stent migration or dislocation. Recurrence of anastomotic stricture after initial success occurred in 9 of 19 patients (47.4%) within 3.5 ± 2.1 months. Sustained stricture resolution was observed in 10 of 19 patients (52.6%), 45.6% from an intent-to-treat perspective.
Limitations |
Uncontrolled study with limited follow-up.
Conclusions |
Temporary placement and removal of PCSEMSs in anastomotic biliary strictures after liver transplantation is feasible, although sometimes demanding. Stent migration may impair final outcome.
