The transjugular intrahepatic portosystemic stent-shunt (TIPS) has successfully been used in the management of refractory variceal bleeding and ascites in patients with portal hypertension. Major drawbacks are the induction of hepatic encephalopathy and shunt dysfunction. We present a 59-year-old woman with alcoholic liver cirrhosis who received a TIPS because of recurrent bleeding from esophageal varices. Stent occlusion occurred 4 mo after placement of the TIPS. Laboratory testing revealed resistance to activated protein C (APC). Combination therapy with low-dose enoxaparin and clopidogrel could not prevent her recurrent stent occlusion. Finally, therapy with high-dose enoxaparin was sufficient to prevent further shunt complications up to now (follow-up period of 1 year). In conclusion, early occlusion of a TIPS warrants testing for thrombophilia. If risk factors are confirmed, anticoagulation should be intensified. There are currently no evidence-based recommendations regarding the best available anticoagulant therapy and surveillance protocol for patients with TIPS.

Background Although endoscopic resection (ER) is recommended as first-choice treatment for early esophageal neoplasia, patients with esophageal varices are considered a high-risk group due to an increased bleeding risk. This systematic review aimed to evaluate the effectiveness and safety of ER in this specific patient category. Methods We searched for studies reporting on clinical outcomes of ER in presence of esophageal varices, irrespective of study design or follow-up time.

Transjugular intrahepatic portosystemic shunt (TIPS) is a widely used surgery for portal hypertension. In clinical practice, the diameter of the stent forming a shunt is usually selected empirically, which will influence the postoperative portal pressure. Clinical studies found that inappropriate portal pressure after TIPS is responsible for poor prognosis; however, there is no scheme to predict postoperative portal pressure.

Introduction: Recurrent portal hypertension (PH) after liver transplant (LT) and its management are not well-studied. This study aims to evaluate the impact of transjugular intrahepatic portosystemic shunt (TIPS) on outcomes of recurrent PH.
Methods: From a cohort of 1846 LT recipients, 36 patients who underwent TIPS creation after LT were identified and considered as cases.

Purpose: To compare costs of intravascular ultrasound (IVUS)-guided transjugular intrahepatic portosystemic shunt (TIPS) creation versus non-IVUS-guided TIPS creation, accounting for differences in procedure time and resource utilization.
Materials And Methods: This single institution retrospective study estimated procedure time and resource utilization from 157 consecutive elective TIPS creation procedures, of which 91 were IVUS-guided and 66 were non-IVUS-guided. Differences in procedure costs were derived using time-driven activity-based costing.

In this article, we provide commentary on the recent article by Zhao . We focus on the shifts in the gut microbiota of patients with hepatitis B virus (HBV)-associated cirrhosis/portal hypertension (PH) following transjugular intrahepatic portosystemic shunt (TIPS) and the implications for understanding the mechanisms, diagnosis, and treatment. By comparing the gut microbiota composition and dynamic changes before and after TIPS in patients with and without hepatic encephalopathy, the authors found an increase in non-probiotic bacteria in those who developed hepatic encephalopathy post-TIPS, with species present only in the hepatic encephalopathy group.
