Dissecting microscope images of sciatic endometriosis model. Top: view of the grafting method, taken during the implementation of the model on postoperative day (POD) 0. The sciatic nerve was exposed (black arrow), and a piece of uterine tissue (white arrow) wrapped around the nerve and fastened with a single suture. Middle: re-exposing the surgery site 21 days later (POD21), when mechanical pain is at a peak, shows that the graft has developed fluid filled cysts (white arrow). Black arrow, sciatic nerve. Bottom: Re-exposing the surgery site on POD49, when mechanical pain is beginning to resolve, shows that the graft is still intact but the fluid is no longer dark red.
