Post-conization residual dysplasia lletz: Analysis of a series of cases

Displacia residual post-conización lletz: Análisis de una serie de casos

A retrospective analytical study of 40 cases taken from a population of 216 patients in which it was possible to carry out a long follow-up of the evolution after the execution of the LLETZ technique (Large Loop Excision of the Transformation Zone), and which culminated in the performing a hysterectomy indicated as definitive treatment for presenting signs of persistence or recurrence of neoplasia. The objective of the study was to establish the diagnostic and / or therapeutic value of the LLETZ, by determining the persistence of residual dysplasia in the samples obtained in the hysterectomy, comparing said results with those of previous diagnoses (cytology, colposcopy, biopsy, LLETZ and cube). In addition, the possible correlation of the results with age and gestational index was explored. The persistence or recurrence of CIN III determined in the final surgical piece (uterus) was 15%, so cytocolposcopic monitoring is still recommended in patients who undergo LLETZ, but this method is safe because in 57 , 5% of the cases, the result of the hysterectomy was negative and in an additional 27.5%, the degree of the lesion was reduced, compared to that found in the LLEIZ.
