The uterus was transected between implant sites. Then, the uterine wall of
each site was incised along the anti-mesometrial border using watchmaker’s
forceps, and peeled back over the mesometrial side where the wall attached
to the decidua. Excess uterine wall tissue was trimmed away leaving a smallamount of mesometrial myometrium at the decidual attachment site as a
landmark. Decidual capsules and the residual mesometrium were then
halved mid-sagittally using a scalpel while viewed under
a stereomicroscope。
