Marking with a Dye to Visualize the Limits of Resection in Breast Conserving Surgery

Abstract

We results. Abstract Objective: To study the technical aspects of the marking of the resection margins with a dye in breast-conserving surgery and to evaluate its aesthetic and oncological impacts. Methods: Injection of methylene blue on a perpendicular path, at a controlled distance from the tumor. The tumor has previously been located by ultrasound or palpation. Then we study the carcinological and aesthetic results. Results: Over a period of 4 years we operated on 36 patients. The average age was 43. Large breasts of average size were found in the majority of cases. Tumor sizes were dominated by T3 tumors and tumors were mostly located in the upper outer quadrant. The most frequently encountered histological types were invasive carcinomas with non specific type. The incisions were classic in more than 80% of cases or sometimes oncoplastic. The aesthetic results were satisfactory in 78% of cases. The carcinological results were marked by invaded margins in 3% of patients. Conclusion: The results of the methylene blue injection technique to secure the excision margins and perform breast conserving surgery are satisfactory from the aesthetic and oncological point of view.
