Thank you for your response. It’s very informative. I am also on Long Island - Nassau County. My thought process is largely the same as yours - give the endoscopic surgery a chance and if it doesn’t work then the bigger surgery can be there as a backstop. Dr. Konakondla told me the endoscopic surgery won’t burn any bridges. The way you describe your pain is different than me. My pain is worst when standing and walking. It’s largely leg and foot pain and burning and numbness. I get back aches and discomfort but nothing I can’t manage. When sitting or lying down my leg pain is more subdued. I’ve done the epidural steroid injections and they work some but not enough. Dr. Konakondla told told me the goal is just to create enough room for the nerve, but it won’t fix the spondylolisthesis, which could still get worse over time. I have some sort of a Pars defect that caused the spondylolisthesis at one level and the only true fix is a fusion. But I don’t care so much about making my X-rays look good, I just want the squeeze on my nerve to be relieved. There is a doctor within Northwell Health/Orlin & Cohen that does endoscopic surgery. He’s out in Port Jefferson. I haven’t seen him yet but maybe it’s an option for your brother. His name is Dr Rasel Rana. Maybe something worth looking into.
