Advantages of the modified double ring areolar incision over the traditional areolar incision in multicentric breast fibroadenoma surgery

BACKGROUND This study was conducted to investigate the clinical advantages of modified double ring areola incision (MDRAI) compared to ordinary areola incision (OAI) in multicentric breast fibroadenoma in women. METHODS Sixty cases of multicentric benign breast tumor were recruited from the First Affiliated Hospital of Bengbu Medical College from January to December 2016. The cases were divided into two groups according to surgical approach: MDRAI (n = 20) and OAI (n = 40). The operation duration, intraoperative blood loss, drainage time, and postoperative recurrence rate in the first six months were compared. RESULTS The mean age and tumor locations were not statistically different between the groups (P > 0.05). However, more lesions and larger tumor diameter were found in the MDRAI group than in the OAI group, with statistical difference (P < 0.05). The operation duration and drainage time of the two groups were not statistically different for unilateral or bilateral lesions (P > 0.05). However, the intraoperative blood loss was statistically different between the two groups (P < 0.05). All 60 cases received six months of follow-up. Eight recurrent cases were found in the OAI group, but none in the MDRAI group. The recurrence rate was significantly different (χ2  = 4.62, P < 0.05). CONCLUSION Compared with OAI, MDRAI offers greater advantages in the aspects of blood loss and recurrence for the treatment of breast benign tumor, especially for multicentric larger lesions.
