Thank you for your question.
As you know, when endometriosis becomes severe, it can start invading the adjacent organs, whether it's the bladder, the bowel, the diaphragm or even the pelvic nerves. The symptoms the patients will present are slightly different, depending on the organ that is injured. Surgery becomes that much more complex, because if it requires that we remove part of ureter or the bladder, then urologists have to be involved. If it involves removing part of the bowel, then the bowel surgeon needs to be involved. When people have recurrent pneumothoraces—air that goes inside the chest because of endometriosis going into the diaphragm and the lung—then you need a thoracic surgeon involved as well.
This is why there's the need for these centres that have all of these people under their umbrella, which we call multidisciplinary care, to be able to tackle this disease.
