Final answer:
The typical incision used for an open cholecystectomy is a subcostal incision made below the right rib cage. Another option is a midline incision, but the subcostal incision is more common.
Step-by-step explanation:
For an open cholecystectomy, the typical incision used is called a subcostal incision. This incision is made just below the right rib cage, allowing access to the gallbladder and surrounding structures. The subcostal incision provides a good view and allows for the removal of the gallbladder.
Another type of incision that may be used is a midline incision. This incision is made vertically through the midline of the abdomen, providing access to the entire abdominal cavity. However, the subcostal incision is more commonly used specifically for cholecystectomy procedures.
