Final answer:
The surgical incision commonly used for Open Cholecystectomy is the Right Subcostal incision, which provides optimal exposure for the surgery.
Step-by-step explanation:
The surgical incision commonly used for Open Cholecystectomy is the Right Subcostal incision. This type of incision, which is also known as the Kocher incision (not to be confused with the subcostal incision named specifically for Emil Theodor Kocher, which is used for biliary surgery), provides optimal exposure of the gallbladder and surrounding structures. A right subcostal incision follows the contour of the right costal margin. While laparoscopic cholecystectomy is more common nowadays due to shorter recovery time and reduced pain post-operation, the open procedure with a right subcostal incision is still used in certain clinical scenarios where laparoscopic surgery is contraindicated or when complications arise during a laparoscopic procedure.
