[Unilateral secondary breast reconstruction using a pedicled dorsal flap sparing the latissimus dorsi (TDAP and MSLD) in patients with a history of total mastectomy for breast cancer. Monocentric observational study]

Abstract

Introduction: The use of pedicled dorsal flaps sparing the latissimus dorsi muscle (TDAP and MSLD flap) is a well-described reconstruction method in breast reconstruction after breast cancer. However, little data exists regarding patient satisfaction after this surgery. The main objective of this study was to evaluate patient satisfaction after unilateral total secondary breast reconstruction using a TDAP or MSLD flap. The secondary objectives corresponded to the evaluation of postoperative complications following this surgery, the evaluation of the duration of the reconstruction and the nature of additional interventions, the evaluation of the functional after-effects, and the evaluation of the chest size when the reconstruction is completed.

Material and method: This is a monocentric, retrospective cohort study, including 22 patients who underwent unilateral secondary total breast reconstruction using a TDAP or MSLD flap between January 1, 2018 and December 31, 2022. Patient satisfaction was assessed using three questionnaires validated in breast reconstruction: the Reconstruction module of the BREAST-Q, the MBROS-S and the MBROS-BI.

Results: The MBROS-S satisfaction score is 71.4%. The MBROS-BI body image score is 62%. With the BREAST-Q, the Satisfaction with Breast score is estimated at 53.1; the Satisfaction with Back score is estimated at 75.5; the physical well-being score regarding the chest is evaluated at 71.7; the physical well-being score concerning the shoulder and back is evaluated at 67.4; the psychosocial well-being score is assessed at 67.4; the sexual well-being score is estimated at 48.7; and for women who have benefited from reconstruction associated with a prosthesis, the satisfaction score regarding the implant is 71.6.

Conclusion: Unilateral total secondary breast reconstruction with a dorsal pedicled flap sparing the latissimus dorsi muscle is an elegant, reliable, and respectful way to reconstruct a breast, and appears to give high levels of satisfaction.
