PRIMARY OBJECTIVE:~I. To evaluate the safety and efficacy of portal vein stenting in patients with portal vein (PV) stenosis and gastrointestinal malignancies, including quality of life measurements.~SECONDARY OBJECTIVES:~I. Stent patency and duration of clinical success related to the intervention. II. Compare the efficacy of portal vein stenting on liver volumes, nutritional status, and laboratory values relative to patients with portal vein stenosis/thrombosis who do not undergo portal vein stenting.~OUTLINE: Patients are assigned to 1 of 2 cohorts.~COHORT A: Patients complete a quality of life (QoL) questionnaire at 2-4 weeks and then 6-8 weeks after portal vein stenting procedure. Patients' medical records are also reviewed.~COHORT B: Patients' medical records are reviewed retrospectively.
This study collects information about the safety and effect of portal vein stenting in gastrointestinal cancer patients with portal vein stenosis. This study may help researchers learn how long the portal vein stays open and free from blockage and the effects of portal vein stenting on patients' overall well-being.
