Clinical results of autologous reconstruction with DIEP flap following nipple-sparing mastectomy / 中国实用外科杂志

ABSTRACT

OBJECTIVE: To analyze the clinical results of autologous reconstruction with DIEP flap following nipplesparing mastectomy and summarize experience.METHODS: From January 2016 to October 2018,DIEP flaps were utilized in 81 surgical cases of immediate breast reconstruction after mastectomy in Huashan Hospital of Fudan University.Success rate,safety,complications and patient satisfaction of nipple-sparing mastectomy(NSM) group(38 cases) and non-NSM(NNSM) group(43 cases) were compared.RESULTS: All DIEP flaps in 81 cases were successful with a flap survival rate of 100%.No skin necrosis,infection,or seroma occurred.There were 1 case(2.6%) of vascular complication and 2 cases(5.3%)of partial fat necrosis in NSM group,and 2 cases(4.7%) of vascular complication and 2 cases(4.7%) of partial fat necrosis in non-NSM group.No statistically significant difference was found between groups.Three cases of partial NAC ischemia(7.9%) happened in NSM group with no complete necrosis.There was a greater satisfaction in NSM group(81.6%) than non-NSM group(72.1%) on the overall impression of breast reconstruction in 6 months after surgeries,but the difference was not significant(P=0.315).Over a median follow-up period of 22 months,no local recurrence or distant metastasis were observed.CONCLUSION: Autologous reconstruction with DIEP flap following nipple-sparing mastectomy is safe and reliable for carefully selected patients when operations are executed with proficient operative skills.Complications are similar in the approach compared with DIEP flap immediate breast reconstruction following non-NSM.The technique has a controllable rate of NAC necrosis and offers the advantage of cosmetic effect.
