Open cholecystectomy requires a right subcostal incision. What is the name of this incision?

The incision typically used for an open cholecystectomy is known as the Kocher incision, which is a right subcostal incision. This incision is specifically designed to access the gallbladder, providing the surgeon with a direct line of sight and access to the operative field in the right upper quadrant of the abdomen.

The Kocher incision facilitates the removal of the gallbladder by allowing for sufficient exposure of the liver and the surrounding structures. It is named after Emil Theodor Kocher, a Swiss surgeon, and is recognized for its effectiveness in gallbladder surgeries as well as other abdominal procedures in that area.

The other options, while specific types of incisions, serve different purposes and are used in different contexts. The Roux-en-Y refers to a specific type of surgical anastomosis and is not an incision type. The McBurney incision is typically used for appendectomies and is positioned in the right iliac fossa. The midline incision, while providing broad access to the abdominal cavity, is not specific to the gallbladder and often is not preferred for an open cholecystectomy. Thus, the Kocher incision is the appropriate and correct choice for this surgical procedure.
