Deep Disease
How is deep infiltrating endometriosis different?
The short answer
Deep infiltrating endometriosis penetrates deeper into tissues beneath the surface lining, rather than staying superficial. It often forms firm nodules and dense scarring, and is more likely to affect nearby organs like the bowel, bladder and ureters.
Deep infiltrating endometriosis (DIE) differs because it penetrates more deeply into the tissues beneath the surface lining, rather than staying more superficial. It often forms firm nodules and dense scarring, known as fibrosis, which can tether structures and distort normal anatomy.
Because of that depth and scarring, DIE is more likely to affect nearby organs like the bowel, bladder, and ureters, sometimes narrowing or pulling on them. Symptoms can be more intense and may include nerve-related pain due to involvement of deeper pelvic spaces. In our practice, evaluating DIE means carefully considering which organs may be involved and planning treatment accordingly. If you suspect DIE, our team can help you understand your options and whether surgery may be appropriate.

Questions people ask next
All deep disease questionsHow is deep infiltrating endometriosis diagnosed without surgery?
Deep infiltrating endometriosis is evaluated without surgery using specialized imaging, mainly an expert-performed transvaginal ultrasound. Pelvic MRI can add detail about the depth and extent of suspected lesions and their relationship to nearby organs.
Can medication alone treat deep infiltrating endometriosis?
Medication alone may reduce pain and bleeding-related symptoms from deep infiltrating endometriosis, but it does not remove deep lesions or scar tissue. Surgery is often part of definitive treatment if organs are affected or symptoms persist despite medication.
Can MRI reliably detect deep infiltrating endometriosis?
MRI can be very helpful for suspecting deep infiltrating endometriosis, especially when read by a radiologist experienced in endometriosis, but it is not a guaranteed yes/no test. A normal MRI does not reliably rule it out, and even deep disease can be missed.
How does deep infiltrating endometriosis affect fertility?
Deep infiltrating endometriosis can make conception harder by distorting pelvic anatomy and limiting how freely the ovaries, tubes, and uterus function. Inflammation and scarring may reduce tubal mobility, even when the ovaries are still producing eggs.
