Choledochal cyst; It is a congenital developmental anomaly of the common bile duct. Its frequency varies according to societies. While it is seen approximately 1 in 100,000 - 150,000 live births in Western societies, this rate is 13,000-14,000 in the USA and 1 in 1,000 in Far East Asian societies. It is 3-4 times more common in the female gender.

It is unpredictable when it will show signs. Although jaundice can be diagnosed due to fever, abdominal pain, or restlessness and abdominal swelling in young children, these findings can actually be seen in many different diseases. Viral hepatitis (Jaundice) is the first example that comes to mind, but its treatment is completely different. However, in today's conditions, ultrasound, which has no radiation side effects, is easy to perform, and does not require anesthesia, is used in the diagnosis of choledochal cyst and is a first-line test.

It is possible to diagnose it with ultrasound, but there are 5 different subtypes of choledochal cyst and their treatments vary. For this reason, attempts are made to detect the subtype using tomography (CT) and magnetic resonance (MR) imaging.

Treatment:

• Although the disease, which can be treated surgically, is not a malignant tumor, if left untreated, it can cause permanent damage to both the liver and pancreas. Although the open surgical method is the classical approach, Choledochal Cyst surgery can now also be performed with the closed method. In our clinic, we performed surgical treatment with the closed method without any problems on 4 patients aged between 8 months and 12 years, and we prefer the closed surgical treatment approach in the first place.
