Final answer:
Salpingostomy is the surgical procedure to remove an obstruction, such as an embryo, from the Fallopian tube while aiming to preserve its functionality.
Step-by-step explanation:
The surgery performed to remove the embryo while preserving the tube is salpingostomy. A salpingostomy entails making an incision in the Fallopian tube to remove an obstruction, such as an ectopic pregnancy, and then suturing the incision to allow for healing, with the intention of preserving the functionality of the tube. This is in contrast to a salpingectomy, which completely removes the Fallopian tube, or a hysterectomy, which removes the uterus, and an oophorectomy, which removes one or both ovaries.
