Final answer:
A choledochojejunostomy is the surgical procedure that connects the common bile duct with the jejunum, the middle section of the small intestine.
Step-by-step explanation:
The surgical procedure that connects the common bile duct with the middle portion of the small intestines is referred to as a choledochojejunostomy. In this procedure, an anastomosis is created between the common bile duct and the jejunum, which is the middle segment of the small intestine after the duodenum and before the ileum.
The other terms listed represent different procedures: Choledochoenterostomy is a more general term for any surgical connection between the common bile duct and the intestine. Choledochostomy refers to the opening of the common bile duct. Choledocholithotomy is the surgical removal of a gallstone from the common bile duct. Finally, Choledochoduodenostomy involves the anastomosis of the common bile duct to the duodenum, the first portion of the small intestine.
Bile plays a vital role in the digestion of fats and is produced in the liver, stored in the gallbladder, and released into the small intestine via the common bile duct, particularly into the duodenum where it helps to emulsify fats.
