Which incision is used in a typical strangulated hernia repair?

The McEvedy's incision is particularly suitable for managing a strangulated hernia because it provides direct access to the inguinal region, where many hernias occur. This incision is designed to facilitate the exploration and potential repair of the hernia, allowing the surgeon to both assess and address any associated complications such as bowel ischemia or necrosis due to strangulation.

Utilizing the McEvedy's incision can enhance visibility and access to the area impacted by the hernia, which is crucial when intervention is needed urgently to relieve strangulation. This method is advantageous in minimizing tissue trauma while providing adequate room to work on the hernia defect and underlying structures.

The other options, while useful in various surgical contexts, do not offer the same level of access or are not specifically tailored for strangulated hernia repairs. For example, the Lanz incision is typically used for appendectomies, Kocher's incision is more appropriate for access to the gallbladder or liver, and the midline incision, although versatile, may not always provide the optimal approach for a direct hernia repair in situations of strangulation. Therefore, McEvedy's incision is the preferred choice in this scenario.
