Role and Technique of VARD/MERP

In the corner of the ICU, on multiple pressors, distended, oliguric, and intubated you’ll find the necrotizing pancreatitis patient. Sounds intimidating, but with the persistence, patience, and the proper care these patients can make it! In this episode from the HPB team at Behind the Knife listen in as we discuss the Step-Up approach, when to surgically intervene, various approaches to pancreatic Necrosectomy, and additional aspects of the multidisciplinary care required for the successful treatment of necrotizing pancreatitis. 

Hosts
Anish J. Jain MD (@anishjayjain) is a current PGY3 General Surgery Resident at Stanford University and a former T32 Research Fellow at the University of Texas MD Anderson Cancer Center.

Jon M. Harrison is a 2nd year HPB Surgery Fellow at Stanford University. He will be joining as faculty at the Massachusetts General Hospital in Boston, MA at the conclusion of his fellowship in July 2024.   

Learning Objectives
·      Develop an understanding of the severity of necrotizing pancreatitis and the proper indications to surgical intervene on this often-tenuous patients. 
·      Develop an understanding of the Step-Up approach and key aspects (reimaging, clinical status, physiologic status, etc.) that determine when to “step-up” treatment for patients with necrotizing pancreatitis.
·      Develop an understanding of long term sequalae and complications associated with necrotizing pancreatitis and operative management
·      Develop an understanding of multidisciplinary care and long-term follow-up necessary for adequate treatment of patients suffering from necrotizing pancreatitis.
