Robotic extraperitoneal approaches have expanded the possibilities of minimally invasive abdominal wall reconstruction. The suprapubic preperitoneal eTEP (PeTEP) technique offers an alternative for selected patients with small-to-medium midline hernias, with or without rectus diastasis, in whom preservation of the retrorectus plane is desirable. This article describes the application of PeTEP in a 58-year-old male with a 3-cm primary umbilical hernia and a 5-cm rectus diastasis, using a suprapubic robotic extraperitoneal approach to achieve functional midline reconstruction while maintaining the integrity of the retrorectus space. The procedure includes pretransversalis access, development of the preperitoneal and pretransversalis planes, midline restoration, and placement of a preperitoneal polypropylene mesh. This technique avoids posterior sheath division, neurovascular bundle manipulation, and retromuscular dissection, thereby reducing potential morbidity in selected patients. This case illustrates the feasibility of PeTEP in a carefully selected patient. The authors do not propose this approach as a replacement for open or transabdominal techniques, but rather as an additional option within a broader reconstructive spectrum.
