Endometriosis · DIE
Deep Infiltrating Endometriosis (DIE)
Deep infiltrating endometriosis – lesions penetrating more than 5mm beneath the peritoneum – is the more aggressive form of endometriosis affecting approximately 20 percent of patients with endometriosis.
Diagnosis
Mapping deep disease
Expert ultrasound using ISUOG IDEA Consensus protocol detects most DIE locations. MRI for additional detail in complex cases. #Enzian classification systematically maps disease extent.
Common sites
Where DIE occurs
- Uterosacral ligaments (most common)
- Recto-vaginal septum
- Bowel wall (typically rectum/sigmoid)
- Bladder wall
- Ureters
- Vaginal fornix
- Round ligaments
Management
Multidisciplinary surgery
Medical management for moderate symptoms. Surgical excision for severe symptoms or impending organ dysfunction. Bowel resection sometimes needed. Ureterolysis or ureteral resection for severe ureteric involvement. Specialised centres with colorectal and urology backup.
Common questions
Frequently asked
Will my DIE need bowel surgery?
Depends on depth. Surface lesions need only shaving; deeper invasion may require partial bowel resection. We assess each case individually.
Can DIE be treated without surgery?
Medical management can control symptoms but does not remove anatomical disease. For severe symptoms or impending complications, surgery is usually needed.
Why was my DIE missed for years?
DIE is often missed without specific imaging protocols. Generalist scanning may not detect deep disease. Specialist evaluation with ISUOG IDEA protocols is more sensitive.
