Diastasis Recti
Rectus diastasis refers to the separation of the rectus abdominis muscles and the associated thinning of the midline. It is an acquired abdominal wall weakness that can very frequently occur in conjunction with an abdominal wall or umbilical hernia.
The PeTEP technique (preperitoneal extended totally extraperitoneal) is a modern, minimally invasive method for treating rectus diastasis and small to medium-sized abdominal wall defects. The goal is to achieve anatomical reconstruction of the abdominal wall while minimizing the burden on the patient.
Access is achieved entirely through an extraperitoneal approach, which protects the peritoneum and prevents direct contact between the mesh and the internal organs. This reduces the risk of adhesions and allows for a stable, tension-free closure of the midline.
In my technique, I prefer to use a so-called “bottom-up” approach starting from the lower abdomen. The linea alba is reconstructed using the inverted Geneva stitch technique, which realigns the rectus abdominis muscles centrally and restores their proper functional alignment.
A particular advantage of this procedure lies in the cosmetic outcome: the incisions are made in the bikini line and are therefore barely visible afterward. This allows for not only functional restoration but also a highly aesthetically pleasing result.
