RESUMO
Background: Breast cancer is the most common cancer affecting women worldwide. In Germany, in almost 70% of cases, women require a complete mastectomy and wish for breast reconstruction which is especially difficult when the breast was previously irradiated. The DIEP flap is then the gold standard for autologous breast reconstruction and shows an overall low complication rate. This study aims to underline the safety of the procedure yet point out potential risk factors for flap edge and fat necrosis in a retrospective series of 1274 DIEP flaps in our center. Patients and Methods: 1274 autologous breast reconstructions with the DIEP flap were performed in 1124 patients between July 2004 and December 2014 in our department. Retrospective risk factor analysis included age, BMI, smoking, chemotherapy and/or radiotherapy and comorbidities. Mean follow-up constituted out of 24 months. Results: Out of 1274 free DIEP flap breast reconstructions, 150 were bilateral reconstructions. In 785 cases the primary indication was previous mastectomy, followed by prior implant-based reconstruction in 265 cases. The total flap loss rate was 0.6%. Patients with a higher BMI and smokers had significantly higher complication rates than the rest of the cohort. Elderly patients ( 65 years), patients with diabetes and ones who had undergone chemo-/ radiotherapy did not present with higher complication rates. Conclusions: The DIEP flap surgery is a well-established method for autologous breast reconstruction with a low complication rate. Yet patient characteristics in terms of risk factors need to be taken into account for result prognosis and satisfactory long-term reconstructive results.

BACKGROUND: The deep inferior epigastric perforator flap has been shown to be a reliable option for autologous breast reconstruction. A further refinement in the transfer of lower abdominal tissue is the superficial inferior epigastric artery (SIEA) flap that does not require any incision of the rectus abdominis fascia or muscle and is superior regarding donor-site morbidity. OBJECTIVES: We conducted a retrospective study to assess reliability and outcomes of autologous breast reconstruction using SIEA flaps. METHODS: We performed autologous breast reconstruction in 1708 patients at our department between 2009 and 2018. Of those, 28 patients that underwent breast reconstruction using a SIEA flap were included for a retrospective chart review. RESULTS: Given an overall flap loss rate of 1.8%, we observed total flap necrosis following a SIEA flap in four patients (13%). All cases were secondary to arterial thrombosis. We further recognized a significant correlation between flap failure and a history of spontaneous deep vein thrombosis (p < 0.0001). There was no statistically significant relationship between flap failure and obesity (BMI > 30 kg/m2;p = 0.9) or flap failure and a history of abdominal operations (p = 0.6). CONCLUSIONS: The SIEA flap provides a reasonable option for autologous breast reconstruction with the great advantage of minimal donor-site morbidity. Nevertheless, its use should be preserved to selected cases with favorable anatomy. We therefore recommend proper patient selection based on preoperative computed tomography angiography, intraoperative clinical evaluation and history of hypercoagulable state.

Background: The most common cancer worldwide in women is breast cancer. The increasing number of cases each year, requires a novel curative approach that can combine oncological treatments and breast reconstruction yielding a pleasing and aesthetic breast that is a definitive and long lasting solution. Thus, the Immediate-DElayed AutoLogous (IDEAL) breast reconstruction principle was created to hold up to the standards of the needs of contemporary women. METHOD: The IDEAL protocol for breast reconstruction was developed in our department in cooperation with our breast surgery unit and describes a two-stage approach that implicates neoadjuvant radio-/ chemotherapy treatment regimes and tumor staging before the mastectomy in order to avoid post-mastectomy radiation. In a second step the breast is then reconstructed with autologous tissue for optimal and natural results. CONCLUSION: More and more patients decide to undergo breast reconstruction after breast cancer. The IDEAL concept offers a life-long and safe solution with a low rate of late complications.

OBJECTIVE: The hypothesis of this parallel group randomized trial testifies if TissuGlu is a safe and an effective alternative to the conventional drainage placement in regard to post-operative fluid management in the abdominal donor site for autologous (DIEP flap) breast reconstruction with a higher postoperative patient quality of life. PATIENTS AND METHODS: Data was collected for 58 women who required to be at min.18 years old with a BMI < 30 and not taking any SSRIs (Selective Serotonin Reuptake Inhibitors).Exclusion criteria: Discharge with indwelling suction drains at the abdominal site or signs of wound infection during hospital stay.The patients were randomized into a study group (donor site closure with application of surgical adhesive without drains) and a control group (donor site closure with drains) using a randomly sorted sealed envelope system.Th e primary outcome was defined as the number of post-operative seroma formations.The secondary endpoint was the evaluation of patient satisfaction with both methods. RESULTS: 58 patients underwent a DIEP reconstruction (29 in the control- and 29 in the study group).Both groups were homogenous. Rate of seroma was 17%(5/29) in the study group and 10%(3/29) in the control group which showed no statistical significance (p-value = 0.71).Smoking and previous abdominal surgery turned out to be a risk factor for seroma formation in the study group.Overall satisfaction was evaluated with a questionnaire and was higher in the study group. CONCLUSION: The abdominal closure with the surgical adhesive seems to be a safe procedure that contributes to patient satisfaction and increases the independence upon discharge in patients with adequate inclusion criteria.

Perioperative management in microsurgery is a key element of success in reconstructive surgery. There are no uniform concepts for this in the German-speaking countries and individual schemes differ significantly from each other, as ascertained in an expert survey. In the course of the 41st Annual Conference of the German-speaking Working Group for Microsurgery (DAM) held in Munich in November 2019, concepts were evaluated and a survey was carried out and summarised as a position paper in due consideration of the scientific literature.

Background Breast cancer is the most common cancer affecting women in Germany. Despite breast-conserving therapy (BCT) being carried out in almost 70% of cases, a high number of women still require complete mastectomy. Prophylactic mastectomy is also indicated for women with a BRCA 1/2 gene mutation. In addition to implant-based heterologous breast reconstruction, autologous breast reconstruction using a DIEP flap has been found to be beneficial, particularly for patients who had prior radiotherapy. This study aims to show that DIEP flap reconstruction surgery is the method of choice for autologous breast reconstruction with a low rate of complications. Patients and Methods Autologous breast reconstruction using a DIEP flap was performed in 1124 patients between July 2004 and December 2014. Retrospective study criteria included potential risk factors such as age, BMI, smoking, chemotherapy and/or radiotherapy, and comorbidities as well as outcome parameters such as postoperative complications. Outcomes were evaluated with a mean follow-up of 24 months. Results A total of 1124 patients underwent 1274 free DIEP flap breast reconstructions, of which 150 were bilateral reconstructions. The primary indication was previous mastectomy in 785 cases, followed by prior implant-based reconstruction in 265 cases. The total flap loss rate was 0.6%. Postoperative surgical revision for abdominal wall hernia was required in 0.2% of cases. The group with a higher BMI and the group of smokers had significantly higher complication rates. Elderly patients (> 65 years), patients who had undergone chemo-/radiotherapy and patients with diabetes did not have higher complication rates. Conclusion DIEP flap surgery is an excellent option for autologous breast reconstruction, with a low rate of donor site morbidity and low complication rates. DIEP flap surgery carried out in a specialised interdisciplinary breast centre in a standardised clinical setting after prior careful patient selection to take account of risk factors such as high BMI and smoking is a reliable method with a low complication rate and satisfactory long-term reconstruction results.
RESUMO
BACKGROUND: Lipofilling is performed in breast cancer patients to optimize the aesthetic outcome following breast reconstruction after mastectomy. Despite its common usage worldwide, little is known about the interaction of the lipoaspirate and dormant cancer cells. Up to date, no risk factors that increase the risk for cancer recurrence have been established. This study aims to identify risk factors for lipofilling candidates after breast cancer and questions the oncological safety of lipofilling in lymph node positive disease. METHODS: Matched retrospective cohort study: the disease-free survival (DFS) between 100 breast cancer patients undergoing a lipofilling after their DIEP-flap reconstruction and 100 matched control patients with no subsequent lipofilling was analyzed. Further, patients were subdivided according to risk factors, which were categorized as patient-dependent factors (PDFs) and tumor-dependent factors (TDFs). DFS and hazard ratios (HR) were compared to identify potential risk factors that may increase cancer recurrence. RESULTS: Median follow-up was 76.5 months from the mastectomy, and 31 months from the startpoint to the end of follow-up. Seven and eleven patients had recurrence in the lipofilling and control group, respectively, presenting with comparable DFS rates and an insignificant HR =0.57, 95% confidence interval (CI): 0.22-1.47, P=0.24. According to subgroup survival analysis, lipofilling increased the risk of recurrence in women with a positive nodal status (P=0.035) and a high-grade neoplasia (P=0.049). CONCLUSIONS: No general increased recurrence risk was observed between the lipofilling and control group. The subgroup analysis identified high-grade neoplasia and positive nodal status to be a risk factor for cancer recurrence. Patients with a known node positive disease have an increased risk of occult micrometastases in their lymph nodes. Further studies are necessary to clarify whether dormant breast cancer cells in form of micrometastases in the lymph nodes can be reactivated by the factors secreted by adipose derived stem cells.
RESUMO
BACKGROUND: With the development of conservative mastectomies, there are an increasing number of women seeking immediate implant based and autologous breast reconstruction. Despite the oncologic safety of the procedures, the focus will be on the timing of reconstruction. METHODS: Our plastic surgery unit is focused primarily on autologous breast reconstruction and is part of an interdisciplinary breast center. We offer immediate breast reconstruction (IBR) with autologous tissue for patients with positive BRCA 1 and 2, ductal carcinoma in situ (DCIS), invasive cancer without margin problems to the skin, as well as to correct poor oncologic and aesthetic breast conserving therapy (BCT) outcomes. In the majority of cases we prefer an Immediate-DElayed AutoLogous (IDEAL) breast reconstruction concept with a two-stage procedure. RESULTS: Over the last 10 years we performed more than 1,600 breast reconstructions with free flaps, performing the deep inferior epigastric perforator (DIEP) flap as our first choice for autologous tissue. We recommend IDEAL breast reconstruction, however approximately 15% of our cases are immediate one stage conservative mastectomies and breast reconstruction with the DIEP flap. CONCLUSIONS: For immediate reconstruction, the aesthetic outcome should not take precedence over oncologic considerations. Immediate one-stage, breast reconstruction with autologous tissue can be offered to the suitable patients which is most likely a healthy women with a small-to-medium sized non ptotic breast receiving a conservative mastectomy. In all other cases, we recommend an IDEAL breast reconstruction approach in order to achieve a final result that is both satisfyingly pleasing and oncologically safe.
