The Anterior Abdominal wall

Hi everyone, still your favourite medic writer and today I will be bringing to us this very interesting anatomical clinical correlate. Will be discussing majorly today about the ABDOMINAL WALL

The abdominal wall consist of the skin located superficially, the underlying connective tissue, the muscles and other anatomical structures which will be discussed during the course of the class, You can always give us feedback in the comment space or via our email

The Abdominal wall encloses the abdominal cavity, i.e the abdominal wall serves as a blanket covering the viserals of the abdomen, the abdominal cavity is just the space of the abdomen containing viserals and other anatomical structures.

Today majorly will be discussing on the clinical correlate of the abdominal wall as said earlier, the clinical correlate will focus on INCISION, incision simply means a cut to create an entrance to a particular part or region.
The major site of incision in the abdominal wall is the LINEA ALBA and it’s due to its low vascularization

An incision that is made through the linea alba. It can be extended the whole length of the abdomen by curving around the umbilicus. The linea alba is poorly vascularised, so blood loss is minimal, and major nerves are avoided. It can be used in any procedure that requires access to the abdominal cavity.

Paramedian
Similar to the median incision, but is performed laterally to the linea alba, providing access to more lateral structures (kidney, spleen and adrenals). This method ligates the blood and nerve supply to muscles medial to the incision, resulting in their atrophy.

Kocher
A Kocher incision ③ begins inferior to the xiphoid process and extends inferolaterally in parallel to the right costal margin. It is mainly used to gain access for gall bladder and/or biliary tree pathology.

Two modifications and extensions of the Kocher incision are possible:

Chevron / rooftop incision or modification ④ – the extension of the incision to the other side of the abdomen. This may be used for oesophagectomy, gastrectomy, bilateral adrenalectomy, hepatic resections, or liver transplantation

Mercedes Benz incision or modification ⑤ – the Chevron incision with a vertical incision and break through the xiphisternum. This may be used for the same indications as the Chevron incision, however classically seen in liver transplantation.

McBurney
A McBurney is a called a ‘grid iron’ incision, because it consists of two perpendicular lines, splitting the fibres of the muscles without cutting them – this allows for excellent healing. McBurney incision is performed at McBurney’s point (1/3 of the distance between the ASIS and the umbilicus) and is used in an open appendicectomy. Thanks everyone for reading.
