title: Positive margins after conization and risk of persistent lesion.
abstract: OBJECTIVE
  The aim of this study was to investigate a method to reduce the frequency of uterine reoperation with no persistent lesion and to identify factors predictive of persistent or recurrent lesions.
  
  
  METHODS
  Of 505 conizations performed by the same surgeon, 71 had positive margins (average patient age = 35.7 +/- 7.7 years). The patients underwent either immediate reoperation or monitoring with a Pap smear and colposcopy.
  
  
  RESULTS
  Histologic assessment of the cervical cone after conization showed positive margins in 14.1% of cases [endocervical and exocervical margins affected in 50 of 505 (9.9%) and 21 of 505 (4.2%) cases, respectively]. Of 59 of these patients (83.1%) who underwent follow-up monitoring over an average of 35.2 months (range: 2.6-180. 8), 12 patients (average age: 40.8 +/- 6.4 years) underwent immediate hysterectomy and 47 (average age 34.0 +/- 7.4 years) benefited from monitoring first [secondary discovery of 19 persistent lesions within 6 months and 9 recurrences within 18 months on average (range: 8.8-48 months)]. Of the 9 patients with recurrent lesions, 7 underwent reintervention and 2 monitoring. Of the 19 patients with persistent lesions, 18 underwent reintervention and 1 monitoring. Normal histology was observed in 29.4% of patients undergoing secondary reoperation for an abnormal smear compared with 66.7% of patients undergoing immediate reoperation (P = 0.04). Severity of lesion and age of patients could not be used to predict the incidence of a persistent or recurring lesion. Seventy-nine percent of conizations had positive endocervical margins in patients with a recurring or persistent lesion compared with 48% in patients with normal follow-up (P = 0.03).
  
  
  CONCLUSIONS
  Cytology and colposcopy follow-up in cases of positive conization margins may help to establish justification for the choice of reoperation, thereby limiting morbidity following repeated surgery.
