Stopping buprenorphine/ naloxone prior to surgery?

I’ve been in and out of the hospital over the last few years. I do not take off my #20 Buprenorphine patch. I’ve been given dilaudid and OxyContin while wearing the patch and they work.
One time the ER docs not understanding the Buprenorphine patch had me take off the patch. Once admitted the doctor and pharmacist did their research and put in my chart that the patch should be left in place so the ER would not remove it in the future.
The patch illuminated my fibromyalgia pain. If it’s helping with my chronic pain I’m unsure because I still have severe back pain.
OxyContin with the buprenorphine helps really well. But because of the opioid crisis they won’t prescribe oxy for break through pain.
If worried about my life expectancy they shouldn’t. I would rather cut my life by 10 years than be in pain.

My reaction was that you would have withdrawal symptoms, but from the most reputable source, they say that gradually reducing is recommended, BUT " In this case report, abrupt cessation of buprenorphine/naloxone at various doses, and after variable durations of treatment, resulted in mild opiate withdrawal lasting over approximately 1–2 days that did not require additional opioid medication or only specific symptom-relieving, non-opioid, medications. Lengthy withdrawal regimens might prolong withdrawal symptoms unnecessarily, perhaps increasing the risk of re-addiction."
So it does look like you have been given excellent advice. You can look it up at this reference. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3723396/
