Serial Comparison of Patient-Reported Outcomes of Immediate Breast Reconstruction: Direct-to-Implant Versus Deep Inferior Epigastric Perforator Flap.

BACKGROUND

Direct-to-implant (DTI) and deep inferior epigastric artery perforator (DIEP) flaps are the two most common methods of immediate breast reconstruction. This study aimed to compare patient-reported outcomes between the two methods and to evaluate whether outcomes change over time.

METHODS

The data of patients who underwent immediate breast reconstruction using DTI or DIEP flaps between July 2017 and October 2021 were retrospectively reviewed. Patients who completed the BREAST-Q Reconstruction Module at 6 months and > 12 months after reconstruction were analyzed. Mann-Whitney and Wilcoxon signed-rank test were used to compare outcome between DTI and DIEP groups, and serial comparisons were performed.

RESULTS

Of 375 patients included in the analysis, 146 patients completed questionnaires > 1 year of follow-up (20.79 ± 8.55 months). The DTI and DIEP groups had 102 (69.9%) and 44 (30.1%) patients, respectively. There were no intergroup differences in the mean scores representing any of the domains at 6 postoperative months. After > 1 year of follow-up, patients who underwent DIEP-flap reconstruction had greater satisfaction with their breast reconstructions (p < 0.001) and greater satisfaction with their overall outcomes (p < 0.001). In the DTI group, satisfaction scores did not change over time in any of the domains. In the DIEP group, however, the mean scores reflecting satisfaction with the breast (p = 0.001), overall outcome (p = 0.045), psychosocial well-being (p = 0.015), and sexual well-being (p = 0.042) significantly increased over long-term follow-up relative to the scores at 6 postoperative months.

CONCLUSIONS

Patient-reported outcomes improved over time in association with DIEP reconstructions, reflecting higher satisfaction levels than those associated with DTI reconstruction.
