A Retrospective Study of Latissimus Dorsi Flap in Immediate Breast Reconstruction

BackgroundThere are many different methods used for immediate breast reconstruction, but the advantages and disadvantages between distinct methods are not reported and compared directly.MethodsWe collected the data of patients who underwent breast reconstruction from 2010 to 2015 and classified a total of 103 patients into three groups: i) skin- or nipple-sparing mastectomy with implant and partial latissimus dorsi flap (MIPLD); ii) skin- or nipple-sparing mastectomy with the whole latissimus dorsi flap (MWLD); and iii) breast-conserving surgery and partial latissimus dorsi flap (BCSPLD). The outcome, safety, and cosmetic outcome of the latissimus dorsi muscle flap with or without implant were reported and compared.ResultsThe procedures were successful in all cases. None of the patients had severe complications. The 5-year distant metastasis-free survival is 94.2%. All the patients exhibited good arm and back function. Based on the evaluation of the BREAST-Q score, the cosmetic outcome of Satisfaction with Breasts was excellent or good in 97.8% of the cases.ConclusionsMIPLD, MWLD, and BCSPLD stand for three distinct methods for immediate breast reconstruction with good outcome and aesthetic effect. They were safe, were easy to perform, and provided quick recovery and good quality of life. Therefore, these three breast reconstructive methods are worthy of widespread use in clinical practice and provide different ways to reconstruct the breast according to the patients’ conditions and preferences.

802 Preservation of a Reconstructed Breast Whilst Undertaking Total Sternal Resection for Metastatic Breast Cancer with a Pedicled Latissimus Dorsi Flap and a Methyl Methacrylate Mesh Sandwich

Background Sternal resection and reconstruction are a complex and challenging procedure that requires a multidisciplinary approach and input from both thoracic and plastic surgeons. Limited data exist on sternal resection and reconstruction for secondary breast malignancies. The goals of sternal and anterior chest wall reconstruction are to maintain chest wall integrity, rigidity, and the negative pressure necessary for respiratory and cardiac functions, protect intrathoracic contents, and restore the chest wall contour. Case Presentation A 40-year-old lady developed a solitary sternal metastatic lesion three years after her initial diagnosis with BRCA2 positive breast cancer. She had previously undergone left mastectomy, axillary clearance and implant reconstruction followed by right prophylactic mastectomy and implant reconstruction. She also had neoadjuvant chemotherapy and adjuvant chest wall radiotherapy. Her solitary sternal metastasis was managed with curative intent by complete sternal resection and a combined alloplastic and autologous sternal reconstruction with methyl methacrylate sandwiched between a polypropylene mesh and covered with a pedicled latissimus dorsi flap. The flap was successfully tunnelled under the previous implant-based breast reconstruction capsule. The surgical margins were clear, there were no post-operative complications and no further disease. The patient achieved good cosmetic outcomes. Conclusions We describe the first case of breast implant preservation whilst undertaking total sternal resection for an isolated sternal metastasise and reconstruction with a pedicle latissimus dorsi flap and methyl methacrylate mesh sandwich. We advocate combined approach with thoracic and plastic surgery, which allows a safe single stage procedure.
