Gastrointestinal bleeding caused by portal vein (PV) stenosis is serious complication after pancreaticoduodenectomy (PD) The purpose of this study is to reveal the long-term clinical outcomes of PV stenting for symptomatic PV stenosis and risk factors of stent related complication. Fifteen patients who underwent portal vein stenting for symptomatic PV stenosis after PD between 2000 and 2018 were retrospectively reviewed. The whole cohort was divided into 9 patients with benign stenosis group (Group-B) and 6 patients with recurrence group (Group-R). The median follow up period was 17.0 (interquartile range 12.0–38.0) months. The technical success rate and clinical success rate was revealed at 93.3% and 86.7%. The primary patency rate of stents was 79.4% and mean patency period was 14.0 (4.0–28.0) months. There was significant difference in time to stenosis and proportion of anticoagulation treatment between 2 groups [2.0 (1.0–4.0) months vs 18.5 (2.5–50.3) months, P = .035 and 100% vs 50%, P = .044. In univariable analysis, stent diameter was found to have a significant correlation with stent occlusion ( P = .036). PV stenting was found to be feasible and safe in the treatment of symptomatic PV stenosis from a long term point of view.
