I'm not sure where you are getting your information but if she is internally laying it is unlikely she can reabsorb anything other than residual fluid. The yolks just seem to remain inert once they have dropped into the abdominal cavity. Speying hens (removing the ovary) is very risky because the blood supply is so large....same with caponizing grown cockerels..... the reproductive organs of both sexes are very active and need a strong blood supply which is not easily tied off. Most vets will not consider doing it. It is more common in hens to leave the ovary but remove the oviduct (sometimes referred to as a hysterectomy) but this means that the bird will need hormonal implants every 3-6 months to prevent ovulation since the ovary is retained and these are expensive at 100-150 a time. The chances of her stopping ovulating naturally are slim, so she will almost certainly continue to produce yolks if her ovary remains and if there is restricted passage down her oviduct or the oviduct is removed, she will internally lay and sadly eventually die..... don't want you to spend a lot more money and be committed to further regular expenditure without knowing the score in advance.
I know I am painting a bit of a black picture of the situation but I have read enough posts here on BYC of people spending a lot on these procedures only to lose the bird a few months down the line or not recover from surgery. Please ensure you have all the information about exactly what they plan to do and the risks before you commit to major intervention.
Good luck and I hope the new vet figures out it is just something simple like a soft shelled egg and manages to remove it
and all my concerns were for nothing.
