title: Correlation between endometriosis-associated dysmenorrhea and the presence of typical or atypical lesions.
abstract: OBJECTIVE
  To evaluate the correlation between the severity of endometriosis-associated dysmenorrhea and the extent of the disease assessed both with a current classification system and with the number and type of endometriosis lesions.
  
  
  METHODS
  Prospective, blinded study.
  
  
  METHODS
  Tertiary care, university hospital.
  
  
  METHODS
  Sixty-five consecutive patients with endometriosis diagnosed at laparoscopy performed for pelvic pain, infertility, or adnexal mass.
  
  
  METHODS
  The patients were submitted preoperatively to a questionnaire including the assessment of the severity of dysmenorrhea by means of a 10-point linear analog scale. Evaluation of all visible signs of endometriosis at laparoscopy was performed by a surgeon not aware of the patients' symptoms.
  
  
  METHODS
  The correlation between the severity of dysmenorrhea and the total score for endometriosis and the partial scores for superficial, deep, and adhesion disease as assessed with a current classification system was evaluated. The severity of dysmenorrhea was also correlated with the total number of superficial implants and with the number of typical, pigmented versus atypical, nonpigmented lesions.
  
  
  RESULTS
  The linear analog score for dysmenorrhea correlated significantly with the total endometriosis score, the partial score for deep endometriosis, and the partial score for adhesions. There was no correlation between the pain score for dysmenorrhea and the partial score for superficial endometriosis, nor with the total number of endometriosis implants, the number of typical implants, or the number of atypical implants.
  
  
  CONCLUSIONS
  The current classification system for endometriosis, devised primarily to formulate a prognosis in infertile patients, correlates significantly with endometriosis-associated dysmenorrhea. The present study does not support the suggested association between atypical implants and the severity of dysmenorrhea.
