Breast reconstruction after mastectomy in patients with obesity: a narrative review.

Background and Objective: Breast reconstruction in patients with obesity presents numerous challenges, both in terms of surgical technique and post-operative complication management. As breast reconstruction techniques continue to evolve, the armamentarium of reconstructive options for patients with obesity has vastly expanded. Options now include immediate or delayed, implant-based, autologous, or hybrid reconstruction. Determining the optimal breast reconstruction in this complex population requires nuanced and experienced decision-making. Methods: A literature search was conducted to identify studies assessing breast reconstruction considerations in patients with obesity. The search was performed on PubMed and was limited to English language studies published between 1990 and 2023. Primary studies, case reports, chart reviews, and qualitative studies were included. Additional articles were identified for inclusion based on a review of references, as well as a web-based search, to identify additional studies that were not captured with the primary search strategy. Key Content and Findings: This narrative review article summarizes the current literature available to guide surgeons in breast reconstruction in patients with obesity. Conclusions: The advancements in oncologic surgery and breast reconstruction techniques have expanded available surgical options, including immediate or delayed implant-based, autologous, or hybrid breast reconstruction. Each approach has its unique advantages, disadvantages, and surgical considerations. Despite the challenges, patients with obesity can achieve favorable aesthetic outcomes through careful assessment of comorbidities and expectation management.
