Associate Professor, Surgery
Cedars Sinai Medical Center
Los Angeles, California, United States
Dr. Kambiz Kosari is an Associate Professor of Surgery and a member of the teaching faculty in the Jim and Eleanor Randall Department of Surgery at Cedars-Sinai Medical Center. He is board certified by the American Board of Surgery and the Transplant Accreditation & Certification Council of the American Society of Transplant Surgeons.
He earned his Bachelor of Science cum laude from the University of California, Los Angeles, and his medical degree from the University of California, San Francisco. He completed his general surgery residency at the University of Minnesota, followed by fellowship training in abdominal organ transplantation at UCLA. After nearly a decade in clinical practice in both employed and private-practice settings, he was recruited in 2018 to join the Comprehensive Transplant Center at Cedars-Sinai as an HPB and liver transplant surgeon.
Dr. Kosari’s clinical practice focuses on the robotic and minimally invasive surgical management of benign and malignant diseases of the liver, biliary system, pancreas, gallbladder, and duodenum, including primary and metastatic hepatobiliary malignancies, pancreatic cancer, neuroendocrine tumors, and complex pancreatic cystic disease. He also manages inflammatory and iatrogenic conditions such as pancreatitis and bile duct injury. As a core member of the liver transplant team, he performs liver transplantation and is actively involved in candidate selection, perioperative care, and the management of complex non-transplant surgical needs, including advanced abdominal wall reconstruction. He has been engaged in robotic surgery since 2010.
Dr. Kosari’s primary research focus is HPB Fast-Track, a health-system–level care redesign initiative that targets delays occurring before specialty referral. By identifying early diagnostic triggers—such as abnormal imaging or laboratory results suggestive of HPB malignancy—and proactively coordinating evaluation, staging, and multidisciplinary decision-making, HPB Fast-Track aims to reduce unwarranted variation and compress the time from the first objective signal of disease to definitive multidisciplinary care planning to two weeks.
