Rare Disease Show Episode 28 - Understanding Caroli Disease ft. Dr. Kiran Peddi

Medical Dialogues presents a rare disease series, exploring the world of uncommon and often misunderstood medical conditions. Rare diseases affect only a small percentage of the population, yet they pose significant diagnostic and management challenges. Through this series, we aim to bring expert insights in a simplified and engaging way to help viewers better understand these complex disorders.

Rare Disease Show Episode-In today’s episode, we explore Caroli Disease, a rare inherited condition that affects the bile ducts within the liver. It is characterized by abnormal dilatation (widening) of the intrahepatic bile ducts, which can lead to bile stasis, recurrent infections, and long-term complications. Although present from birth, many patients remain asymptomatic for years, and the disease is often diagnosed later in adulthood when symptoms such as recurrent abdominal pain, fever, or episodes of cholangitis begin to appear. In some cases, Caroli Disease may also be associated with other conditions like liver fibrosis, increasing the complexity of care. Early recognition, imaging-based diagnosis, and timely management are crucial to prevent complications and improve patient outcomes.

In this episode, Dr. Kiran Peddi, Director of the IBD Centre of Excellence at Yashoda Hospitals, Hyderabad, shares his expert insights while addressing key questions from the Medical Dialogues team. He discusses why the disease can remain silent for years, highlights the warning signs patients should not ignore, explains challenges in managing recurrent infections, and offers clarity on treatment options ranging from medical management to surgery and liver transplantation. The discussion also touches upon cancer risk, screening strategies, and practical lifestyle measures that can help patients better manage their condition and improve their quality of life.

1. Can you explain what is Caroli Disease and why is it classified as a rare disease?

2. Many patients aren't diagnosed until adulthood despite this being a congenital (birth) condition. Why does it remain 'silent' for so long, and what are the most common 'red flag' symptoms that finally lead to a diagnosis?

3. Recurrent cholangitis (bile duct infection) is a major hallmark. Why are these infections so difficult to clear, and how do you manage a patient who is becoming resistant to standard antibiotics?

4. Talking about the management- Liver Transplant vs. Resection: if the disease is limited to just one lobe of the liver, is surgery a 'cure'? At what point does a patient move from 'managing symptoms' to needing a liver transplant?

5. The Cancer Risk: We all know, it’s a heavy topic, but there is an increased risk of cholangiocarcinoma (bile duct cancer). How do you screen for this?

6. Beyond medications, what can patients do in their daily lives—dietary or otherwise—to reduce the burden on their biliary system?

7. Lastly, if a listener has just been diagnosed today and feels overwhelmed by the rarity of their condition, what is the one thing you want them to know about the road ahead?"
