Study 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.

What researchers measure

Primary outcomes

  1. Pre-TIPS intestinal transit time (measured in hours and minutes), via smart pill in patients with cirrhosis

    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.

    Time frame: 14 Weeks

  2. Post TIPS intestinal transit time (measured in hours and minutes), via smart pill in patients with cirrhosis

    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.

    Time frame: 14 Weeks
