Abstract

The management of preinvasive cervical lesions has the objective to ensure the absence of invasive lesions and to prevent progression to cancer. Excisional procedures have been preferred to treat these lesions as they report the presence of unsuspected invasive lesions and the status of surgical margins, allowing inferring full excision when such are free of disease. The purpose of this study is to determine whether Straight Wire Excision of the Transformation Zone (SWETZ) is a better alternative than Large Loop Excision of the Transformation Zone (LLETZ-cone) as a type 3 excision of the Transformation Zone (TZ) to reduce incomplete excision and concerning other outcomes of surgical interest. Randomized controlled trial including women who needed type 3 excision of the TZ referred to a colposcopy clinic after cytological screening between January 2008 thru December 2011. The interventions were performed using local anesthesia and sedation in an inpatient basis by different experienced surgeons. The study enrolled and randomized 164 women, of which 82 were allocated to each group. After exclusions, 78 remained in SWETZ and 76 in LLETZ-cone groups for the analysis of outcomes of surgical interest and 52 and 54, respectively, for ...Continue Reading
