Although there is no complete envelope for fibroids, as the fibroids grow up, the fibroids compress the surrounding muscle wall fibers and form a pseudo-envelope, and the boundary between the two is clear, so that there is a loose mesh gap between the fibroids and the uterine muscle wall, and after cutting the uterine muscle wall, the fibroids will mostly leap out from the muscle wall, and it is very easy to peel out the fibroids from the pseudo-envelope. Therefore, it is perfectly feasible to remove the fibroids and preserve the uterus. However, if a uterus has many fibroids (sometimes dozens or hundreds of fibroids), and the patient is too old to have children, the fibroid removal surgery may bleed more than the removal of the uterus, and the uterus may be removed in a few years, so it is more recommended to remove the uterus. Of course the specifics also depend on the patient’s opinion, after all, the uterus is theirs, not the doctor’s.
