In this case, Dr. Rockson Liu performs a robotic eTEP retrorectus Rives-Stoppa repair of an upper midline primary ventral hernia that was partially reducible but mostly incarcerated, and greater than 6 cm in a 63-year-old female. Robotic ports were placed directly into the retrorectus space. Using the crossover technique, the retrorectus spaces were combined with a preperitoneal bridge of the peritoneum. The defects were closed robotically, and a medium-weight, macroporous polypropylene mesh was placed within the retrorectus space.

Here, Dr. Canon at the University of Arkansas for Medical Sciences performs a prophylactic laparoscopic bilateral gonadectomy to reduce her future risk for intra-abdominal testicular malignancies. Final pathology results showed a rare case of bilateral germ cell neoplasia in situ and bilateral paratesticular leiomyomas and reinforced the decision to intervene early allowing for the removal of the gonads prior to their conversion to formal germ cell tumors.
