Objective For palliation of extrahepatic bile duct obstruction, self-expandable metal stents (SEMS) are superior to plastic stents
in terms of stent patency and occurrence of stent dysfunction. We assessed health-related quality of life (HRQoL) after stent
placement to investigate whether this also results in a difference in HRQoL between patients treated with a plastic stent or SEMS.
Patients and methods This randomized multicenter trial included 219 patients who were randomized to receive plastic stent
(n =73) or SEMS [uncovered (n= 75) and covered (n =71); n =146] placement. HRQoL was assessed with two general
questionnaires (EQ-5D-3L and QLQ-C30) and one disease-specific questionnaire (PAN-26). Scores were analyzed using linear
mixed model regression and included all patients with baseline and at least one follow-up measurement.
Results HRQoL data were available in 140 of 219 patients (64%); 71 patients (32%) declined participation and in eight patients
(4%) only baseline questionnaires were available. On the QLQ-C30, the interaction between follow-up time and type of stent was
significantly different on two of five functional scales [physical functioning (P= 0.004) and emotional functioning (P =0.01)] in favor
of patients with a SEMS. In addition, patients with SEMS reported significantly less frequent symptoms of fatigue (P =0.01), loss
of appetite (P= 0.02), and nausea and vomiting (0.04) over time. The EQ-VAS score decreased with time in both treatment
groups, indicating a statistically significant decrease in HRQoL over time.
Conclusion In patients with inoperable malignant extrahepatic bile duct obstruction, SEMS placement results in better scores for
general and disease-specific HRQoL over time compared with plastic stent placement.
