A surgical incision in the abdominal wall is called a laparotomy. It may be made in the midline, to either side of the midline or in the flank on either side. The choice of location of the laparotomy depends on a number of factors:

1 The avascularity of the linea alba resulting in slow healing; this is a particular problem especially in cattle where the linea alba is extensive.

2 The bulk and weight of the abdominal contents leading to slow healing and risk of herniation.

3 In the dog the ventral sheath of the rectus abdominis is particularly strong, and failure to suture this may result in breakdown of a midline incision.

4 In a midline incision contraction of the muscles of the abdominal wall tends to retract the wound edges laterally.

5 Flank incisions should be parallel to the muscle fibres to minimise bleeding from the vascular muscular tissue.

6 In the cow a further complication of a midline incision is that branches of the mammary vein may cross the midline to anastomose with the opposite mammary vein.
