Overview
Brief Summary
The effect of portal hypertension on gastrointestinal motility, and how reversal or improvement in portal hypertension may alter gastrointestinal motility, remains unclear and further research is needed. Additionally, patients with cirrhosis have altered gut microflora, particularly rich in lactobacilli, including enterococci and bifidobacteria. Transjugular Intraheptic Portosystemic Shunting (TIPS) is a procedure performed by interventional radiologists, in which a connection is made between the portal and venous circulations, allowing high pressure portal blood to more easily enter the systemic circulation and bypass the liver; thus effectively decreased portal pressure.

Eligibility Criteria
Inclusion Criteria
- •Patients with either radiographic or biopsy proven decompensated cirrhosis (as determined by ascites, variceal hemorrhage, encephalopathy or jaundice).
- •Patients undergoing an elective TIPS for any standard of care established indication (examples: worsening ascites, recurrent variceal bleeding).
Exclusion Criteria
- •Pregnant women.
- •Patients unwilling or unable to provide informed consent.
- •Patients undergoing an emergent TIPS for acute or subacute variceal hemorrhage.
- •Patients with diabetes, significant cardiovascular, renal or other chronic disease which has been known to affect intestinal motility.
- •Previously diagnosed gastroparesis or other GI dysmotility disorder.
- •Patients currently taking narcotics, antibiotics excluding rifaximin, prokinetic medications or lactulose.
- •Patients with a history of gastric bezoar.
- •Patients with a history of multiple intestinal surgeries or GI surgery within the past 3 months.
- •Patients with a history of gastrointestinal strictures, fistulas, or physiological or mechanical obstruction.
- •Patients with a history of gastrointestinal strictures, fistulas, or physiological or mechanical obstruction.
Outcomes
Primary Outcomes
Post TIPS intestinal transit time (measured in hours and minutes), via smart pill in patients with cirrhosis
Time Frame: 14 Weeks
Due to small sample size, Wilcoxon rank-sum test will be used to compare the continuous variable of gut transit times. A p-value of \<0.05 will be considered statistically significant.
Pre-TIPS intestinal transit time (measured in hours and minutes), via smart pill in patients with cirrhosis
Time Frame: 14 Weeks
Due to small sample size, Wilcoxon rank-sum test will be used to compare the continuous variable of gut transit times. A p-value of \<0.05 will be considered statistically significant.
