Pillet et al reported a score for predicting deep infiltrating endometriosis in a woman undergoing surgery for an endometrioma. The authors are from multiple institutions in France.
Patient selection: woman undergoing surgery for an endometrioma
Parameters:
(1) 10 cm VAS score for dyspareunia or GI symptoms (pain on defecation during menstruation; intestinal cyclic pain)
(2) duration of pain in months
(3) dysmenorrhea
(4) infertility (absence of pregnancy after >= 12 months of unprotected intercourse)

= SUM(points for all of the parameters)
Interpretation:
• minimum score: 0
• maximum score: 53
• The higher the score the greater the risk for deep infiltrating endometriosis.
