Endometriosis can’t always be confirmed with imaging alone. The gold standard for diagnosis is surgery.
During a laparoscopy or robotic procedure, the abdomen is carefully examined for endometriosis, any suspicious biopsies or lesions are removed, and the tissue is sent to a pathologist for analysis under a microscope. If endometrial glands and stroma are identified, the diagnosis is confirmed.
In some cases, endometriosis is discovered unexpectedly during another surgery or through a biopsy done for a different reason. But when endometriosis is suspected, surgical evaluation remains the most definitive way to make the diagnosis.
