Just thought this might be interesting info. I had a laparoscopy last year in August for an ovarian cyst, but they found quite advanced endo. I had an MRI after this and There was endo adhesions on my bowel and close to my ureter so they decided it needed to be removed.
At the consultant appointment, they said that as my MRI was in November, they were going to push for me to have my op before April as if it was later than that, I would need another MRI. He said that a lot of women are falling into a cycle in this way and surgeons are trying to push to NHS to prioritize cases to overcome this cycle.
I don't know if this pressure will mean a quick operation for definite, but I did get my pre op appointment through yesterday for mid March so I am hopeful.
