Background: Biliary tract leaks occur in over 10% of patients undergoing liver transplantation and are the most common cause of biliary tract-related death in these patients. A number of treatment options are available, but a standard approach has not been established.
Methods: Twenty-six patients were retrospectively studied who had post-transplantation leaks develop with special reference to those who underwent endoscopic placement of a "leak-bridging" stent.
Results: Endoscopic retrograde cholangiography was performed in all cases with no procedure-related complications. Twenty-four patients had a leak-bridging stent, 1 a transpapillary stent, and 1 a nasobiliary drain. Leak resolution occurred in 23 cases (88%) after initial stent placement. The median time to stent removal was 8 weeks. Three patients did not respond to initial treatment; 2 were successfully treated with another stent and a single patient required surgical repair. Four deaths occurred during follow-up, all unrelated to the biliary leak.
Conclusions: Placement of a leak-bridging stent is a safe and effective initial treatment for post-liver transplantation biliary leaks.

Alcohol Relapse After Liver Transplantation: Risk Factors, Outcomes, and a Comparison of Risk Stratification Models.
Gastro Hep Adv
September 2024
Division of Gastroenterology and Hepatology, Duke University, Durham, North Carolina.
Background And Aims: Alcohol-related liver disease is a leading cause of liver transplantation (LT) in the United States; however, alcohol relapse remains a risk, and real-world assessment of relapse prediction scores is lacking. The primary aim of this study was to assess risk factors for alcohol relapse and compare effectiveness of pre-existing risk scores (e.g.

Division of Gastroenterology and Hepatology, University of California, San Francisco, San Francisco, CA.
Background Aims: Patients with hepatocellular carcinoma (HCC) meeting UNOS-downstaging (DS) criteria have excellent post-liver transplantation (LT) outcomes. Studies on HCC beyond UNOS-DS criteria ("All-comers" (AC)) have been limited by small sample size and short follow-up time, prompting this analysis.
Approach Results: 326 patients meeting UNOS-DS and 190 meeting AC criteria from 9 LT centers across 5 UNOS regions were enrolled from 2015 to 2023 and prospectively followed.

Therap Adv Gastroenterol
January 2025
Division of Gastroenterology and Hepatology, Department of Internal Medicine, King Faisal Specialist Hospital and Research Center, P. O. Box 3354, Riyadh 11121, Saudi Arabia.
Background: Inflammatory bowel disease (IBD) occurs in up to 70%-80% of patients with primary sclerosing cholangitis (PSC). Oral vancomycin therapy (OVT) has been reported to be effective in the treatment of IBD associated with PSC (IBD-PSC).
Objectives: To examine the effectiveness and safety of OVT in the treatment of IBD-PSC by performing a systematic review and pooled analysis of the literature.
Celiac trunk angiography with balloon occlusion of splenic artery for diagnosis and treatment of splenic steal syndrome.
Radiol Case Rep

University of Maryland School of Medicine, Department of Diagnostic Radiology and Nuclear Medicine, Division of Vascular and Interventional Radiology, Baltimore, MD, USA.
Splenic steal syndrome (SSS) post liver transplant is a potential cause of graft dysfunction in the setting of peripheral hepatic arterial bed resistance and redirection of blood flow to a dominant splenic artery resulting in reduction of hepatic arterial inflow. We report utilization of balloon occlusion of the proximal splenic artery as an objective measure to confirm the diagnosis of SSS in a patient with orthotopic liver transplant followed by successful treatment with proximal splenic artery embolization using Gelfoam and Amplatzer vascular plug. Written informed consent for the publication of this case report was obtained from the patient.

In solid organs post-transplant, bacterial infections can complicate the course of recovery with devastating consequences, such as graft loss and death. We provide an expert review on early post-liver transplant bacterial infections, with a focus on infections with multi-drug-resistant organism (MDRO) etiologies. Best practice recommendations are derived from a combination of available evidence and expert consensus.
