During which surgical procedure is a connection between the gallbladder and duodenum created?

The procedure that involves creating a connection between the gallbladder and duodenum is known as cholecystoduodenostomy. This surgical technique is typically employed when it is necessary to establish a direct pathway for bile flow from the gallbladder into the duodenum, often due to complications like gallstones or issues related to the biliary tree. By directly connecting these two structures, the procedure allows bile to assist in digestion, which would otherwise be hindered if there were blockages or functional impairments in the normal pathway.

In contrast, the other options pertain to different types of surgical connections and do not involve a direct connection between the gallbladder and duodenum. Pancreatojejunostomy involves connecting the pancreas to the jejunum, primarily performed in the treatment of pancreatic disease or when a portion of the pancreas is removed. Choledochojejunostomy creates a connection between the common bile duct and the jejunum, often used when there's an obstruction in the bile duct. The Whipple procedure, formally known as pancreaticoduodenectomy, entails the removal of the head of the pancreas, the duodenum, part of the bile duct, gallbladder, and sometimes parts of the stomach,
