Background:
Understanding of donor-site morbidity and satisfaction after breast reconstruction is limited. There are few previous studies comparing satisfaction with different donor sites in breast reconstruction. This study aimed to examine the long-term patient-reported satisfaction with the donor site of latissimus dorsi (LD) flaps in comparison to the deep inferior epigastric artery perforator (DIEP) flaps. Further, a systematic review of previously published studies was conducted.
Methods:
In this retrospective cross-sectional study, all women who underwent breast reconstructions with either LD or DIEP flap following mastectomy and radiotherapy between 2007 and 2017 were included; patient-reported satisfaction was assessed using the BREAST-Q reconstruction module. For the systematic review, studies examining patient-reported abdominal satisfaction and well-being, and meeting the PICO (Population, Intervention, Comparison, and Outcome) criteria were included.
Results:
Eligible and responding participants were divided into the LD (n = 135 patients) and DIEP (n = 118 patients) flap groups. Impairment due to muscular weakness of the donor site was more common in the LD group than that of the DIEP group. Bulging was common in the DIEP group and increased over time. Regarding the esthetic appearance of the donor site, the patients in the DIEP group were less satisfied than the LD group. The systematic review showed that most of the patients were dissatisfied with their abdomen after the operation.
Conclusion:
Patients who have undergone DIEP flap for breast reconstruction are less satisfied with the donor-site esthetics than those who have undergone LD flap. Patient-reported abdominal bulging was common in the DIEP group and the number seemed to increase over time. Most patients were not satisfied with their abdominal scarring postoperatively, as per the systematic review. These results may indicate a need for more nuanced preoperative patient information, as well as improvements in the surgical management of the donor site, for DIEP flap reconstructions.
