THE REVISED AMERICAN FERTILITY SOCIETY CLASSIFICATION OF ENDOMETRIOSIS - REPRODUCIBILITY OF SCORING

Objective: To assess the reproducibility in staging endometriosis using the revised American Fertility Society (AFS) classification of endometriosis. Design: Visual documentation of laparoscopies of 315 women with endometriosis was scored by the investigators and a blinded reviewer. Setting: Patients from private practice institutional setting. Participants: Patients who participated in a multicenter trial to study the efficacy and safety of a GnRH agonist (GnRH-a). Interventions: Laparascopic visual documentation of the extent of endometriosis before and after 6 months of GnRH-a therapy. Main Outcome Measure: The reproducibility of the AFS classification system comparing scoring during laparoscopy and by a blinded reviewer. Results: Good to fair agreement scoring endometriosis between the investigator and the blinded reviewer was noted. Conclusions: Visual documentation may be used to determine the stage of endometriosis using the revised AFS classification guidelines.
