Choledochal cyst is a type of cyst found in the bile ducts. The spelling of the word is pronounced as "ko-luh-doh-kuhl sɪst", with emphasis placed on the second syllable. It is derived from Latin and Greek words combined together, "chole-" meaning bile, "dochus" meaning duct, and "kystis" meaning bladder. This condition is rare and can cause discomfort, abdominal pain, and jaundice. It can be treated with surgery, but sometimes might also require liver transplantation in severe cases.
A choledochal cyst refers to a congenital abnormality and structural anomaly involving the bile ducts, specifically the common bile duct or the cystic duct. This cystic dilation of the bile ducts primarily affects infants and children, but can also occur in adults.
The common bile duct functions to transport bile from the liver and gallbladder to the small intestine, aiding in digestion. However, in the case of a choledochal cyst, there is an abnormal, sac-like dilation or expansion of the bile ducts due to a developmental or inherent defect.
The exact cause of choledochal cysts remains unknown, but it has been associated with a congenital anomaly in the formation of the bile ducts. The cystic dilation tends to hinder the normal flow of bile, leading to various complications and potential health risks, such as jaundice, abdominal pain, recurrent infections, liver enlargement, pancreatitis, and increased risk of developing certain cancers.
Surgical intervention is commonly recommended to remove the cyst and reestablish normal bile flow. The preferred surgical approach varies depending on the specific location and extent of the cyst. Treatment typically involves excising the affected portion of the bile ducts and reconstructing normal bile duct anatomy to restore normal biliary drainage.
Regular follow-up and long-term monitoring are crucial for individuals who have undergone treatment for choledochal cysts to ensure optimal liver function and prevent potential complications.
The word "Choledochal" is derived from the Greek terms "chole" meaning bile and "dochos" meaning duct or channel. The term "cyst" comes from the Greek "kystis" meaning a sac or bladder-like structure. Therefore, the etymology of "Choledochal Cyst" refers to a cyst-like dilation or abnormality in the bile ducts.
