What incision is typically performed for an appendicectomy?

The incision typically performed for an appendicectomy is the Lanz incision. This incision is specifically designed for access to the appendix through the right iliac fossa, which is the standard approach in appendectomy procedures. It is a transverse incision located over the McBurney point, which corresponds to the underlying location of the appendix. This incision provides optimal exposure to the appendix while minimizing tissue trauma and scarring.

The Lanz incision is preferred because it allows for direct access to the appendix and facilitates effective surgical intervention. It is also associated with lower rates of postoperative complications compared to other incision types.

In contrast, other options such as the McEvedy's incision and Rutherford Morrison incision are generally used for different types of abdominal surgeries, often in the context of hernia repairs or other intra-abdominal procedures where broader access might be needed. The Pfannenstiel incision, which is a transverse incision often used in gynecological surgeries, is not appropriate for appendicectomy as it does not provide the best access to the right iliac fossa where the appendix is located. Overall, the Lanz incision is the most suitable choice for performing an appendicectomy due to its specific advantages in this surgical context.
