Clinical Programs

Our team of hepatologists, nurse practitioners, and physician assistants treat patients with a variety of complex liver conditions. Here are a few multidisciplinary clinics that are offered to serve the unique needs of our patient populations.

 

A rare genetic condition that often affects the liver and heart, Alagille Syndrome is usually diagnosed within the first few year's of a child's life. Under the medical direction of Dr. Noelle Ebel, our Alagille Syndrome Program brings together experts from the Betty Irene Moore Children’s Heart Center,  Pulmonary Artery Reconstruction (PAR) Program, Pediatric Transplant Center and Neurosurgery program to make sure that children with this rare disease get the specialized treatment they require.

Portal Vein Anomalies Program

Portal vein anomalies are uncommon conditions in which the main vein supplying blood to the liver forms abnormally, is narrowed, or is blocked. This can disrupt normal liver blood flow and lead to complications such as portal hypertension or liver enlargement. At Stanford Children’s, these conditions are evaluated and managed by a specialized multidisciplinary team using imaging, medical care, and, when needed, interventional or surgical treatments.

Primary Sclerosing Cholangitis

Primary Sclerosing Cholangitis (PSC) is a disease of the bile ducts. The bile ducts become inflammed or blocked, allowing bile to accumulate in the liver. Some patients with PSC are also diagnosed with inflammatory bowel disease. In these cases, our hepatologists work closely with the IBD Center to determine treatment. 

When one of the two heart ventricles does not develop fully, the heart has diffculty pumping blood throughout the whole body. Our Single Ventricle Program brings together a team of experts representing the many organ systems affected to help care for children with this rare, congenital heart disease. 

The Biliary Atresia is a rare condition in infants in which the bile ducts become blocked or absent, preventing bile from draining from the liver and leading to progressive liver damage. The program provides comprehensive, multidisciplinary care that includes advanced diagnostic testing, medical management, nutritional support, the Kasai procedure, and pediatric liver transplantation when needed. 

Research Highlight

Through involvement in clinical registries, outcomes research, and investigational trials, the hepatology team seeks to advance the medical science and better understand the mechanisms that cause liver diseases as well as the indicators for better response to different treatments.

Here we highlight clinical projects that are currently recruiting or are about to begin. Visit our Publications to view a list of recently research findings.


The BOLD Study

Stanford is proud to be one of two recruiting sites in California for the Biliary Atresia and the Use of Odevixibat in Treating Liver Disease (BOLD) study. Under the direction of site investigator Dr. Amrita Narang, the trial will evaluate if a child with biliary atresia who has undergone a Kasai hepatoportoenterostomy can delay or avoid liver transplant by taking the investigational drug odevixibat. The BOLD  study is the first pivotal Phase 3 clinical trial for infants with biliary atresia.

Webinars & Medias Resources

We are proud to be actively involved in multiple networks and organizations dedicated to the care of children with acute and chronic liver conditions. Below, you can explore our recent national presentations, webinars, and media materials from the Pediatric Hepatology.

Q&A: Answering the ‘Why’ Behind Liver Transplant Inequity, Healthier Happy Lives Blog

Black and Hispanic children awaiting liver transplants often face longer wait times and higher risk of complications due to disparities in referral timing and access to specialized care. Dr. Peace Dike is working to better understand and address these inequities so that access to lifesaving transplants is determined by medical need rather than background.
