Pros and cons of immediate Vicryl mesh insertion after lumpectomy.

BACKGROUND: Lumpectomy is a standard surgery for breast cancer; however, it results in breast deformity, especially after radiation therapy. Wider surgical margin correlates lower local recurrence rate. However, bigger defect brings worse cosmetic outcome. The use of a simple filler for the defect is expected. We aimed to improve the cosmetic outcome by using an absorbable Vicryl mesh for breast reconstruction immediately post-lumpectomy.

METHODS: One sheet of Vicryl woven mesh was prepared for insertion, washed the cavity with natural saline, and placed into the space. The cosmetic outcome was scored for the size, shape, scar, and softness of the breast. The size, shape, color, and position of the nipple-areola complex were also scored. Adverse events were collected retrospectively.

RESULTS: From April 2008 to October 2014, 24 female patients received immediate Vicryl mesh insertion. A lumpectomy only group was recruited for cosmetic analysis. All patients received postsurgical radiotherapy. The mean cosmetic assessment score was 8.0 and 9.1 of 12 for the Vicryl mesh group and lumpectomy only group, respectively (P = 0.17). Sixteen patients had adverse events such as erythema at approximately 2 weeks post-surgery. No significant differences were shown except adverse events between two groups. No patient has had local recurrence thus far.

CONCLUSION: Immediate Vicryl mesh insertion leads to significantly increased incidence of postoperative complications and delay in commencement of adjuvant radiotherapy. Furthermore, the cosmetic outcomes are not superior to that of no reconstruction. The development of superior biomaterials is anticipated for breast reconstruction after lumpectomy.
