What does SIDNEY BREJT research?

Dr. Brejt studies challenges related to liver transplants in children, particularly issues with the bile ducts that sometimes occur after the surgery. One common complication is biliary stricture, which is a narrowing of the bile duct that can lead to serious problems. To manage this, he has developed and evaluated a specific treatment protocol that involves a series of dilation sessions to widen the bile duct and reduce the need for multiple invasive procedures, ultimately improving the patient's recovery experience.

Key findings

  • The three-session biliary dilation protocol reduced total drainage time by a significant margin compared to less systematic approaches.
  • Patients who underwent this protocol had improved outcomes, resulting in fewer repeated interventions.
  • The structured approach to dilation demonstrates a notable reduction in complications related to biliary strictures after liver transplants in pediatric patients.
