Preperitoneal space, is it an ideal layer for endoscopic sublay repair of ventral hernia?

[Figure omitted. [...]if space separation and mesh repair is refined to preperitoneal layer, no musculoaponeurotic structure need be cut off, and consequently the damage will be extremely minor. Short-term discomfort was observed in 11 patients in the first 3 months post-operatively and was relieved in the next 1 to 3 months. [...]it is potential to separate the visceral sac as large as possible.
