Final answer:
The Subcostal (Kocher) incision would most likely be used for a cholecystectomy with intraoperative cholangiogram and possible common bile duct exploration.
Step-by-step explanation:
The most likely incision to be used for a cholecystectomy with intraoperative cholangiogram and possible common bile duct exploration would be the Subcostal (Kocher) incision. This incision is made horizontally just below the ribs on the right side of the abdomen. It provides good exposure to the gallbladder and common bile duct, allowing for the necessary surgical interventions.
