Dear ndea, The best person to answer your question is your gynecologist, especially if you have symptoms. Endometriosis is a condition, which is usually exist inside the abdominal cavity, while tummy tuck surgery is outside the abdominal cavity. So, as long as you gynecologist is giving you the green light for tummy tuck surgery, you can proceed with it from a plastic surgeons perspective. You have to realize that not all results are the same, because experience, skills and aesthetic eye are critical for good outcome. So, do your due diligence carefully and choose your surgeon wisely, to avoid bad result and need for corrective surgery. Always, consult with experienced board certified plastic surgeons who operate in accredited surgery center for your safety. Most importantly, check the before and after pictures in the photo gallery, to make sure that they are numerous, consistent and attractive with flat stomach, tight and youthful skin, nice belly button, improve body posture and low scar. Best of luck, Dr Widder
