I have had two lots of surgery involving my bowel. It should be done at a BGSE centre by a specialized gynae and bowel surgery. My bowel endo was diagnosed through a lap.
My second operation was about 5 months later. I had my bowel shaved and unstuck from my uterus, I also had endo removed from POD and UL. At this op I had some bleeding but it was fixed during surgery. The surgery was quite significant due to the extent of the endo. I was in hospital for 2 days. The recovery was not pleasant and I couldn't do much for the first two weeks. But I did heal quite quickly. I had the surgery at the end of July 2013 and got married at the end of September. I couldn't lift for a while at least 6 weeks and I wasn't back to myself for a few months but it did offer some relief.
I then had a bowel resection last year in May as my endo had gone through my bowel wall and was causing excruciating pain. The surgery took about 6 hours and I was prepared in case I needed a stoma. The surgery went well in the sense the excised the endo, the bowel was removed and no stomas was needed. But I had internal bleeding which was not picked up at the time. I was rushed back in to theatre the next day as I had lost a lot of blood and required surgery and transfusions. I was in for 7 days but was followed up weekly for 3 weeks (I begged them to release me lol). I was really ill in hospital and was terrified but I managed. I did recover after a few months and went back to work (I have a desk job) after about 7/8 weeks. I had effects from the surgery for a while - my bowel took a while to adjust but it did go back to normal.
I was very, very unlucky but it is a risk of surgery which I knew at the time. It is so difficult to decide what is right for you. I do not regret having surgery for me it has meant I am pain free from my endo.
I should also say I fell pregnant after my operations (once I was recovered enough and got the go ahead from my surgeons) so good luck.
