The most common cause of common biliary duct dilatation is obstruction due to gallstones, states the Radiology Assistant. Another cause of obstruction besides gallstones is stricture, or narrowing, of the common bile duct.Know More
Strictures of the bile duct may be due to tumors, such as cholangiocarcinoma, gallbladder adenocarcinoma or pancreatic adenocarcinoma, or metastatic disease. Strictures may also result from inflammation from pancreatitis, radiation or chemotherapy, biliary parasites, AIDS cholangiopathy or primary sclerosing cholangitis, according to the Radiology Assistant.
If there are no gallstones and no strictures causing obstruction, the cause of the bile duct dilatation may be non-obstructive biliary disease, notes the Radiology Assistant. Examples of non-obstructive biliary diseases are Caroli disease, choledochal cyst, recurrent pyogenic cholangitis and primary sclerosing cholangitis.
Caroli disease is a genetically inherited disease that results in dilatation of the ducts within the liver, according to the Radiology Assistant. It is associated with polycystic kidney disease. Choledochal cyst is a dilatation of the bile ducts outside the liver that is present at birth. Recurrent pyogenic cholangitis is common in Asian countries and is associated with biliary parasites. Primary sclerosing cholangitis results in strictures in the bile ducts and is associated with ulcerative colitis and Crohn's disease.Learn more about Gastrointestinal Issues
Gallstones tend to form when the gallbladder does not close correctly, or the bile contains high levels of cholesterol or bilirubin, according to Mayo Clinic. Cholesterol gallstones take on a yellow color, while bilirubin gallstones are brown or black in color. They cause pain that lasts up to an hour.Full Answer >
According to WebMD, the type of treatment a doctor chooses for treating a twisted colon depends on where the obstruction occurs in the colon, but typically those options include use of a barium enema, a lighted scope or surgery. While non-surgical methods are less invasive, they are often not permanent, and as many as half of those treated with such have a occurrence of the issue.Full Answer >
Bowel obstructions are treated rather than cured, depending on what caused the obstruction. They are caused by physical conditions that prevent stool from moving through the intestines, explains the National Cancer Institute. Bowel obstructions occur when something other than fecal matter blocks the large or small intestine.Full Answer >
Treatment for an intestinal blockage varies based on whether the obstruction is partial or complete, reports Mayo Clinic. However, treatment usually requires hospitalization. A partial obstruction may resolve itself with the addition of a low-fiber diet, but a complete obstruction may require surgery or other forms of intervention.Full Answer >
