Does your doctor expect adhesions to be a problem necessitating converting your surgery to a laparotomy? Often the consent forms for a lap surgery state that you consent to your doctor converting to an abdominal cut if necessary. If you do not wish for your doctor to convert to be able to complete your surgery, you will need to talk to her about what to do. It is possible that she will not want to do surgery at all if she cannot convert to an abdominal incision if necessary. She may be able to tell you exactly what would occur before she would convert and share with you how often it has been necessary for her to convert in the past. She may have to stop your surgery without completely all of the necessary procedures if you do not wish her to convert and you would need to schedule a second surgery for a later date if a laparotomy is needed. Likely there are other scenarios as well.
The pros of letting your doctor convert would be one surgery, less time under anesthesia, one recovery, etc. The cons would be a longer healing period, bigger incision, maybe more pain with recovery.
I would suggest you sit down and carefully discuss your feelings with your doctor prior to surgery. You might want to schedule a consultation type appointment to go over these issues prior to your Pre Op appointment.
I have had a hysteroscopy, laparosocpy (endo was cleaned up from a variety of places including ovaries), and D&C all at the same time. However, I did not have an ovary removed. I did well following the surgery and don't really remember pain after the first day. I was uncomfortable a bit but not really in a lot of pain. I was tired but I was able to care for my 3 and 5 year olds and even took a trip a few hours from home about a week after surgery.
I had an incision in my belly button and one at the pubic bone. Both were about an inch long. It was day surgery so I was sent home after I was awake and could use the restroom.
I wish you all the best for your upcoming procedure and hope it goes well!
