Final answer:
Common hepatic duct obstruction is caused by a gallstone blocked in the cystic duct, leading to a disruption in bile flow and the development of symptoms such as pain and jaundice.
Step-by-step explanation:
The condition described in the question is a common hepatic duct obstruction, which occurs when a gallstone becomes impacted in the cystic duct, leading to an extrinsic obstruction of the common hepatic duct. This obstruction can disrupt the flow of bile from the liver, resulting in symptoms such as pain and jaundice. If a gallstone blocks the bile duct, the bile cannot be excreted, and bilirubin, a bile pigment, backs up into the liver and is passed via the blood, causing jaundice. Treatment for common hepatic duct obstruction may involve surgical removal of the gallstone and/or other interventions to restore normal bile flow.
