A McBurney incision is specifically indicated for an appendectomy procedure. This type of incision is made in the right lower quadrant of the abdomen and provides optimal access to the appendix, which is typically located in this area. The incision is placed in a way that minimizes tissue disruption while allowing the surgeon to effectively visualize and remove the inflamed appendix, which is often the case in appendicitis.

In contrast, the other procedures listed would utilize different types of incisions. For example, a cholecystectomy, which involves the removal of the gallbladder, might use an incision beneath the right rib cage or be performed laparoscopically. Similarly, a herniorrhaphy, which repairs a hernia, would typically be accessed through an incision made directly over the hernia site. A gastrectomy, involving the removal of part or all of the stomach, would necessitate a larger incision, usually along the midline or upper abdomen.

The specific nature of the McBurney incision makes it particularly suited for appendectomies, highlighting the importance of selecting the appropriate incision type based on the surgical procedure being performed.
