Abstract
We have discussed the peritoneal flap or hernia sac repair for midline ventral hernias in the previous chapter. In this chapter, we discuss the use of the technique in transverse ventral hernias, both medially, where the scar involves the recti, and laterally, where the scar involves the lateral muscles.
Again, the name "peritoneal flap" is actually a misnomer. The "hernia sac" is not just peritoneum but is also composed of scar tissue and attenuated abdominal wall fascia.
It can be thin and peritoneum-like, but usually it is comprised of stronger tissue.
