Patients with cirrhosis have increased surgical risk and require care team expertise. We explored the association between center cirrhosis surgical volume and post-operative mortality in a large VA dataset. In this retrospective cohort study of 14,500 major surgeries in patients with cirrhosis, we found in adjusted analysis that high-volume centers (>16 surgeries in past year) had a 36% reduced hazard of post-operative mortality through 90 days versus low-volume centers (<9 surgeries in past year; hazard ratio 0.

Article Synopsis
  • Patients with cirrhosis have a higher risk of dying after surgery, often due to complications from portal hypertension, and some believe preoperative TIPS (transjugular intrahepatic portosystemic shunt) placement might help reduce this risk.
  • A study analyzed data from Veterans Health Administration patients who had major surgery between 2008-2022, comparing outcomes between those who had TIPS placed within 6 months of surgery and those who did not.
  • Results showed that TIPS placement was linked to a significantly higher risk of postoperative mortality and indicated poorer liver function right before surgery, suggesting that TIPS may not be beneficial for all patients with cirrhosis undergoing surgery.

Article Synopsis
  • Traditional transplant centers typically use their own teams for liver recovery after circulatory death (DCD), but there's a need to consider outside teams (nontransplant program procurement teams, NTPT) due to broader organ sharing.
  • A study analyzed national data comparing liver transplants from NTPT and local teams, finding similar one-year liver graft survival rates (88.9% for NTPT vs. 88.6% for TPT).
  • The study concluded that the source of the procurement team didn't significantly impact graft failure, suggesting transplant centers can safely utilize DCD livers from local surgical teams.
