This study was conducted in Chinese patients to determine whether stable cases of seromas would resolve without treatment. Methods: A retrospective review of 45 consecutive cases of immediate breast reconstruction with LD flap from April 2012 to February 2017 was conducted. The scope of the seroma was demarcated with a marker pen, and cases that remained stable over time (i.e. the size of the seroma did not increase) were observed without treatment. The measured outcomes included the incidence ofseromas, the volume and duration of postoperative wound drainage, and other demographic characteristics. Results: Twenty-four patients (53.3%) developed a seroma at the donor site. Of these, 21 patients (87.5%) did not require treatment, and the seroma resolved over time. The mean duration of a sustained serol-na was 6.8 ± 1.4 weeks (range: 4-9 weeks). Conclusions: This study observed the scope and progression of the seromas and found that seromas at the LD donor sites resolved over time without treatnlent.展开更多

Methods: From Jan. 2000 to Jul. 2005, 74 staged 0-II patients (mean age 39) were performed immediate breast reconstruction with autologous tissue either using LTD flaps or pedicled TRAM flaps with supplemental implants when necessary after mastectomy due to breast cancer and the charts were reviewed. Results: The age, marriage and menses status did not affect the selection of modalities and the need of implants. In 74 patients, 62 cases (83.8%) were performed LTD reconstruction with 13 implants and 12 cases received TRAM with 1 implant. The difference in need of implants or not between the two modalities had no statistical significance (P=0.442, Fisher' exact test). Aesthetic results judged as good or fair were in 88% patients and the cosmetic effects between LTD and TRAM groups or implant and non-implant groups had no differences. All reconstructions were successful, with 4.1% cumulative locoregional recurrence and 100% overall survival by following up to 66 months (median 9 months). The DFS and RFS between the two modalities had no significant differences by log rank test. Conclusion: Immediate autologous tissue reconstruction makes it possible to regain the natural and symmetric contour of breast without increased local recurrence. The LTD flap reconstruction is a suitable option for most Chinese women as well as the pedicled TRAM flap.展开更多

None of the reports, however, involved female Chinese patients. Methods A retrospective study of 24 female patients was conducted to guide the selection of methods of surgical reconstruction. The patients were divided into three groups according to the degree of thoracic tissue development. Type I (mild): Limited tissue loss which can be treated with simple filling with autologous fat and/or an artificial breast implant. Type II (moderate): Moderate thoracic tissue hypoplasia where the breast parenchyma can still offer adequate implant coverage. Mammoplasty using a latissimus dorsi muscular flap with an implant was performed in this group. The flap was used to fill the infraclavicular hollow, and the implant was placed in the dual-plane pocket. Type Ⅲ (severe): Severe thoracic tissue hypoplasia, without sufficient parenchyma to offer implant coverage. A latissimus dorsi muscular flap was used to form a total submuscular pocket in which an implant was placed. Results The numbers of Type Ⅰ, Ⅱ, and Ⅲ patients were 15, 3, and 6, respectively. All of the flaps and injected fat demonstrated good survival. Satisfactory cosmetic results were exhibited during the follow-up period of 1 to 9 years. Conclusions Although this group of patients showed varied conditions, they can be roughly divided into three types according to the degree of thoracic tissue development. In our experience, this classification is simple and useful in choosing the breast reconstruction options.展开更多
