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.
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.

| Measure | Description | Time Frame |
|---|---|---|
| Patency rate (Cohort A) | Defined by successful stent placement and described as N (%) of patients with corresponding exact 95% confidence interval. | Up to 8 weeks after stent placement |
| Transfusion rate (Cohort A) | N (%) of patients receiving transfusion with corresponding exact 95% confidence interval. Instances of multiple transfusions per patient will also be described. | Up to 8 weeks after stent placement |
| Rate of paracenteses for ascites (Cohort A) | N (%) of patients receiving paracenteses with corresponding exact 95% confidence interval. Instances of multiple paracenteses per patient will also be described. | Up to 8 weeks after stent placement |
| Duration of clinical success (Cohort A) | Mean, median, standard deviation, and minimum/maximum values will be described. | Up to 8 weeks after stent placement |
| Change in nutritional status (Cohort A) | Based on albumin, pre-albumin, weight, body fat, and body surface area (BSA). Methods such as repeated measures analysis of variance (ANOVA) with post-hoc Tukey test and generalized estimating equations (GEE) will be used to assess pre- and post- differences. | Baseline up to 30 days post procedure |
| Change in bleeding risk (Cohort A) | Based on platelet count and coagulation factors. Methods such as repeated measures ANOVA with post-hoc Tukey test and GEE will be used to assess pre- and post- differences. | Baseline up to 30 days post procedure |

Inclusion Criteria:
COHORT A: All patients will undergo initial staging and treatment as per the institution standard of care. Patients will be considered eligible for porto-mesenteric venous stenting (PVS) if:
COHORT B: Patients who have thrombosis/stenosis of the main portal vein but who did not undergo stenting

| Change in liver function (Cohort A) | Methods such as repeated measures ANOVA with post-hoc Tukey test and GEE will be used to assess pre- and post- differences. | Baseline up to 30 days post procedure |
| Change in liver volume (Cohort A) | Methods such as repeated measures ANOVA with post-hoc Tukey test and GEE will be used to assess pre- and post- differences. | Baseline up to 30 days post procedure |
| Change in quality of life (QoL) (Cohort A) | Will be assessed based on National Comprehensive Cancer Network - Hepatibiliary Symptom Index Questionnaire - 18 item. Methods such as repeated measures ANOVA with post-hoc Tukey test and GEE will be used to assess pre- and post- differences. For QoL will also present effect size, defined as the magnitude of the differences in relation to the standard deviation of the scores, which will be reflective of the strength of the effect of portal stenting on QoL. | Baseline up to 30 days post procedure |
| Number of transfusions (Cohort A and B) | Methods such as paired t-tests, conditional logistic regression, and generalized linear modeling will be used to compare differences by cohort. | Up to 8 weeks post procedure |
| Number of paracentesis for ascites (Cohort A and B) | Methods such as paired t-tests, conditional logistic regression, and generalized linear modeling will be used to compare differences by cohort. | Up to 8 weeks post procedure |
| Liver volume (Cohort A and B) | Methods such as paired t-tests, conditional logistic regression, and generalized linear modeling will be used to compare differences by cohort. | Up to 8 weeks post procedure |
