Mean serum bilirubin levels in randomized patients treated with PDT plus stenting (group A, n = 20) and of patients with stenting alone (group B, n = 19). In groups A and B, bilirubin levels remained elevated after stenting. Post-PDT bilirubin levels decreased in group A (P < 0.01). The error bars are the SEM.
