In summary, in our ongoing efforts to provide comprehensive liver care, the GI division at Stanford proudly announces the addition of five hepatologists to our team. With diverse backgrounds and areas of expertise, these physicians will extend our footprint throughout the Bay Area, with locations in Emeryville, Tri Valley Hospital, San Jose, Redwood City, and Palo Alto. Their collective commitment to patient-centered care, cutting-edge research, and community outreach underscores our mission to serve the entire region with excellence in liver health. This expansion marks a significant leap forward in our endeavor to provide accessible and high-quality care to all individuals affected by liver disease across the Bay Area.

Liver Transplant News

Advancements and Updates for Stanford's Liver Transplant Program

The liver transplant program at Stanford has continued to excel with 134 liver transplants performed in 2023, a record number for Stanford.   Moreover, the increase in volume has been accompanied by an improved transplant rate (58.4%) and amongst adult liver transplant programs in northern California, Stanford has the highest deceased donor transplant rate.  This measurement also has the largest impact on survival after listing.  In addition, Stanford's observed organ acceptance is significantly higher than expected.  These accomplishments have translated into a significant  reduction in median wait time to transplant with our current median wait time being the shortest of all liver transplant programs in northern California (13.4 months).  In addition to the record number of transplant performed, our survival also continues to improve. Our 1-year graft  (94.87%)and patient (93.36%) survival outcomes are higher than expected and higher than the national average and we achieved similar results for 3-year graft and patient survival (  Moreover, our transplant population has a higher percent of high MELD and hospitalized (ICU and non-ICU patients) than the overall region. With the addition of 5 new transplant hepatologists as detailed elsewhere in the newsletter, we are able to rapidly see patients who require evaluation for liver transplantation for cirrhosis, refractory alcoholic hepatitis, and hepatocellular cancer.  To schedule a patient for liver transplant evaluation, you may call 650-498-7878.  If the referral is urgent or an inpatient transfer such as acute liver failure you may call 650-723-4696 and ask for the hepatologist on-call.

In 2023, the Abdominal Transplant Program leadership transitioned to Dr. Marc Melcher from Dr. Carlos Esquivel who has stepped down from this role.  We are indebted to Dr. Esquivel who became Division Chief in 1998 and under his leadership over the past 25 years, has built a world class abdominal transplant program.  Dr. Melcher is a graduate of Columbia University School of Medicine and completed his general surgery training at Stanford University and Liver Transplant Fellowship training at UCSF.  He joined the faculty at Stanford in 2006 and was promoted to Full Professor in 2022.  His areas of research focused on the application of algorithms and advanced technologies to prove access to organ transplantation in areas such as paired exchange programs to optimize life donation in kidney transplant.  He is working to  develop AI algorithms to accurately assess steatosis in donor liver biopsies. He also has in the role of  oxygenated machine perfusion technologies to increase donor utilization and reduce organ discards. Thus, Stanford continues to lead the field in liver transplantation, showcasing remarkable achievements and pioneering research to enhance patient care and outcomes.
