“I had the opportunity to learn a great deal from the team. One of my patients, three weeks ago, was a 10-year-old child with severe ulcerative colitis. Through the CHOP team’s guidance, I learned about biologic therapy and its role in treating severe disease. The patient’s parents were initially afraid to start infliximab, but after I explained its safety and benefits based on what I had learned, they agreed to the treatment. The patient was on hormone therapy and azathioprine. At first, there was no response to the treatment. After biologic therapy, the patient’s condition improved significantly after starting infliximab.
I also learned how to select appropriate therapeutic strategies and follow evidence-based treatment algorithms while managing a patient after liver transplantation. This experience strengthened my ability to approach complex and severe clinical cases. After I, as a GI, followed up, I learned that another patient with liver transplantation is now doing better.
Perhaps the most valuable lesson I learned was the importance of a multidisciplinary team. I saw how different specialists work closely together, support one another, and collaborate to provide the best possible care for their patients.
I am currently applying these recommendations and guideline-based approaches in the management of another patient with severe Crohn’s disease, following the principles and treatment strategies I learned from the CHOP team.”
