Following on from that, there seems to be a reluctance to go forward with diagnostic surgery. This is quite strange seeing as it is the only way to get the histology samples to confirm the endometriosis diagnosis. It is not as if one would just have a surgery for the purpose of diagnosis.

No surgeon would do that. It would be unethical. It would also be surgery to treat and try to remove as much of the endometriosis at the same time.
