I had ablation a year ago and just had a full hysterectomy 5 weeks ago yesterday. I had an ovarian cyst removed as a bikini cut more than 20 years ago. I've also had a variety (7 or 8) other full abdominal (belly button to vagina) opening surgeries, as well as abdominalplasty to repair damage from medications, and have a permanent stoma and ileostomy, as a result of Crohn's.
All that to say, if the doctor can perform abdominal surgery on me with no complications, I'm sure you are a fine candidate for the surgery as well.
Now, I had the ablation because of cysts and dark brown bleeding constantly, so there were concerns that my body wasn't completely shedding the uterine lining each month. The ablation made sense for that. I had the hysterectomy because BCP wasn't controlling migraines, ovarian cysts, or fibroid cysts and there was fluid backing up into my Fallopian tubes on a semi-regular basis .... These were becoming much larger health issues, so I talked with my doctor and we decided the hysterectomy made sense. Recovery has been slow, but that's because it was yet another belly button to vagina cut. There are other options for a hysterectomy that result in much shorter recovery time .... Vaginal, laparoscopy, robotic .....
If you chose ablation now, you may still be looking at a hysterectomy a few years down the road ....
