What is enteric duplication cyst?
Enteric duplication cysts (EDCs) are rare congenital malformations formed during the embryonic development of the digestive tract. They are usually detected prenatally or in the first years of life.
What is the tumor marker for cholangiocarcinoma?
The tumor marker carbohydrate antigen 19-9 (CA 19-9) can be evaluated in pancreatic and bile duct malignancies, as well as in benign cholestasis. A serum CA 19-9 level greater than 100 U/mL (normal < 40 U/mL) has 75% sensitivity and 80% specificity in identifying patients with PSC who have cholangiocarcinoma.
What are the types of cholangiocarcinoma?
Currently, cholangiocarcinoma is classified into the following types according to its anatomic location along the biliary tree: intrahepatic, perihilar or distal extrahepatic cholangiocarcinoma. These cholangiocarcinoma types differ in their biological behavior and management.
How common are duplication cysts?
Duplication cysts are rare congenital anomalies of the alimentary tract. The majority of duplication cysts are symptomatic within the first 2 years of life.
Can you get a cyst in your intestines?
Gastrointestinal cysts, also known as enteric or intestinal duplication cysts, are most often seen in the ileum of the small intestine, esophagus, and stomach. They can be small and round or long and tubular.
Does anyone survive cholangiocarcinoma?
Cholangiocarcinoma (bile duct cancer) is a deadly disease. Even when it’s detected early, the five year survival rates for people with this cancer is less than 25%.
Which is risk factor for cholangiocarcinoma?
There are several established risk factors for CC including parasitic infections, primary sclerosing cholangitis, biliary-duct cysts, hepatolithiasis, and toxins.
How many stages of cholangiocarcinoma are there?
There are actually 3 different staging systems for bile duct cancers, depending on where they start: Intrahepatic bile duct cancers (those starting within the liver)
How do you get rid of a cyst that is duplicated?
The definitive treatment for a duplication cyst is surgery. The surgical approach can be open (laparotomy or thoracotomy) or minimally-invasive (laparoscopic or thoracoscopic) and depends on the expertise of the surgeon. Symptomatic cases: Early surgery is recommended in all the symptomatic cases.
What is an enteric duplication cyst?
Enteric Duplication Cysts. Enteric duplication cysts, often simply referred to as duplications, can occur anywhere in the alimentary tract from mouth to anus (Gross et al., 1952; Holcomb et al., 1989). Duplications can be cystic or tubular and consist of an inner lining of GI epithelium and an outer layer of smooth muscle.

Enteric cysts, also known as enteric duplication cysts, are of either esophageal or gastroenteric origin. The majority are found in infants or children younger than 15 years. Patients generally present with dysphagia, cough, and vomiting.
What are the indications for intraductal invasion of cholangiocarcinoma?
