Which of the following incisions is oblique?

1. Epigastric

2. Kocher

3. Paramedian

4. Pfannenstiel

The correct answer is: Kocher

The Kocher incision is classified as an oblique incision because it follows a slanted approach to access the underlying structures, particularly the right upper quadrant of the abdomen where the gallbladder is located. An oblique incision is characterized by its angle relative to the midline of the body, often running diagonally. This is particularly advantageous in surgeries in the abdomen, allowing for less tension on the sutures and potentially better cosmetic outcomes. In the context of surgical choices, other incision types mentioned are categorized differently. The epigastric incision is typically made horizontally across the upper abdomen. The paramedian incision runs parallel to the midline but is vertical in orientation, and the Pfannenstiel incision is a transverse incision often used for gynecological surgeries. Each of these incision types serves distinct purposes and provides access to different anatomical areas, but they do not share the oblique characteristic that defines the Kocher incision.
