Single-Stage Immediate Breast Reconstruction Using a Skin-Sparing Incision and Definitive Saline Implants Compared with a Two-Stage Reconstruction Using Tissue Expansion Plus Implants
Notice bibliographique
Résumé
BACKGROUND: Losing a breast to cancer has significant psychological ramifications, and it has been shown that minimizing this loss can have a profound impact. As a result, breast-conserving therapy or mastectomy followed by breast reconstruction have become the preferred surgical treatments for breast cancer. Limited available breast skin following mastectomy has traditionally necessitated the use of autologous tissue or tissue expansion; however, when reconstructing larger breasts, autologous tissue grafts rarely provide enough tissue and tissue expanders can often take several months to achieve the necessary tissue volume. The skin-sparing mastectomy offers a solution to this lack of skin, and as a result many new options for immediate breast reconstruction have presented. The present pilot study looks at a new method of immediate breast reconstruction involving a Wise pattern skin-sparing mastectomy with placement of a definitive, submuscular saline implant as a way to maintain a large breast size without requiring the patient to undergo a long and painful tissue expansion process. METHODS: A retrospective, case-control study was performed on 12 women who had undergone bilateral mastectomies with immediate reconstruction either with a tissue expander and later placement of definitive saline implant (control group) (n=5) or who had undergone a single-stage reconstruction involving the placement of a definitive submuscular saline implant (experimental group) (n=7). Patients were compared with respect to change in breast size, number of reoperations and operations in total, as well as satisfaction with their reconstruction. RESULTS: Patient satisfaction in both groups was relatively high and there was no statistically significant difference found between the two groups. The experimental group decreased in bra size by 1.4 cup sizes on average whereas the control group experienced no change on average; however, one-third of patient data had to be discarded for various reasons, making the change in size measurement inconclusive. Finally, the average number of reoperations was higher in the experimental group than the control (1.57 versus 1.00); however, the total number of operations required was less (2.57 versus 2.80). CONCLUSIONS: Immediate breast reconstruction using a definitive submuscular saline implant is a viable option for reconstruction in women with larger breasts that deserves further study on a larger scale. Although limited by sample size, the present pilot study showed, with a large effect size, that this new procedure reduces the total number of operations required for reconstruction when compared with a tissue expander followed by an implant while maintaining an equally high level of patient satisfaction.

Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.
