Volumetric muscle loss (VML) is the traumatic/surgical loss of skeletal muscle, causing aesthetic damage and functional impairment. Suboptimal current surgical treatments are driving research towards the development of optimised regenerative therapies. The grafting of bioengineered scaffolds derived from decellularized skeletal muscle may be a valid option to promote structural and functional healing. In this work, a cellular human diaphragm was considered as a scaffold material for VML treatment. Decellularization occurred through four detergent-enzymatic protocols involving (1) sodium dodecyl sulfate (SDS), (2) SDS + Tergitol^TM, (3) sodium deoxycholate, and (4) Tergitol^TM. After decellularization, cells, DNA (≤50 ng/mg of tissue), and muscle fibres were efficiently removed, with the preservation of collagen/elastin and 60%–70% of the glycosaminoglycan component. The detergent-enzymatic treatments did not affect the expression of specific extracellular matrix markers (Collagen I and IV, Laminin), while causing the loss of HLA-DR expression to produce non-immunogenic grafts. Adipose-derived stem cells grown by indirect co-culture with decellularized samples maintained 80%–90% viability, demonstrating the biosafety of the scaffolds. Overall, the tested protocols were quite equivalent, with the patches treated by SDS + Tergitol^TM showing better collagen preservation. After subcutaneous implant in Balb/c mice, these acellular diaphragmatic grafts did not elicit a severe immune reaction, integrating with the host tissue.

Background: Capsular contracture (CC) represents one of the most common complications in breast reconstruction surgery, impairing final result and patients’ well-being. The role of acellular dermal matrixes (ADM) has been widely described for the treatment and prevention of contracture. The aim of the study was to evaluate the efficacy and safety of complete implant coverage with porcine-derived ADM in preventing CC limiting complications. In addition, patients’ reported outcomes were evaluated in order to define the role of ADM in improving sexual, physical and psychosocial well-being and satisfaction. Methods: 42 patients who underwent surgical treatment of 46 contracted reconstructed breasts from May 2018th to May 2019th were collected in the two groups (ADM group vs. Control group). Results: The ADM group showed lower rate of CC recurrence and a higher rate of implant losses and minor complications. A significant difference was observed in red breast syndrome (27.3% in the ADM group vs. absent in control the group) and skin ulceration rates (18.2% in the ADM group vs. 4.18% in the control group). As for patients’ perceived outcomes, the ADM group showed a statistically significant higher postoperative Satisfaction of Breast Scale score compared to the control group. In addition, a significant difference was observed in the improvement of Physical Well-Being of the Chest Scale and the Satisfaction of Breast Scale after surgery, in favor to the ADM group. Conclusion: Complete implant coverage with ADM may reduce the risk of CC recurrence in breast reconstruction. An accurate patient selection allows minimizing complications improving patient well-being and satisfaction.

Background: Due to the great impact of bariatric surgery on the overweight epidemic, the number of post-bariatric body-contouring procedures is constantly increasing worldwide. The portable incisional negative pressure wound therapy (piNPWT) is a promising medical device for accelerating wounds closure and controlling post-operative complication, which have been shown promising results in post-bariatric population. We aimed to evaluate the role of piNPWT in optimizing wound healing and controlling post-operative complications after a post-bariatric brachioplasty. Patients and Methods: 26 post-bariatric female patients who underwent a brachioplasty followed by either a piNPWT (14 cases) or a standard wound treatment (12 controls) were analyzed. The number of post-operative dressing changes, the rate of local post-operative complications (re-operation, hematoma and serosa development, dehiscence and necrosis), the time to dry as well as the scar quality and hospitalization length were evaluated. Results: None of the patients prematurely stopped treatment with piNPWT due to intolerance. The piNPWT patient group showed a significant lower healing time as well as a significant reduction of the number of post-operative dressing changes and hospital stay. Despite the scarring process was excellent from the functional point of view in the long term, we noticed a higher rate of hyperchromic scarring at 90 days after surgery. Conclusion: The piNPWT is a cost-effective and user-friendly medical tool that increase and promote wound healing. We suggest the use of this device in post-bariatric patients who undergo a brachioplasty, especially if there is the need to minimize the number of post-operative dressing changes.

Background: Ear avulsion is a rare complication of different traumas, such as car accidents, human or animal bites and stab wounds, and can result in dramatic cosmetic consequences for the patient. Ear replantation, revascularization, and reattachment are the options offering best aesthetic results. But venous outflow insufficiency is responsible for a high rate of failures. Leeching is one the most efficient methods to relieve venous congestion. It has been used as an alternative venous outflow in case of severe impairment of the physiologic one. Methods: We present a case of successful rescue of a congested reattached ear by leeching after subtotal avulsion, along with a review of the literature on cases of avulsed auricle reconstruction salvaged by hirudotherapy. Data were collected and analyzed to identify a best regimen to deal with venous congestion. Results: More than 130 cases of avulsed auricle savage are described in the literature, in a fourth of which leech therapy was used in the management of venous congestion. Discussion: In case of both venous outflow deficit or absence, leeches are a potentially successful option to correct the congestion while new veins reestablish normal physiology. The need for anticoagulant/antiaggregant therapy, antibiotics, and often blood transfusion are the main pitfalls of leeching. Conclusion: Leeches can be considered a salvage method for ear replantation and reattachment in those cases that lack venous outflow in the presence of valid arterial inflow.

Background: Due to the high demand of post-bariatric surgeries, the number of litigation cases is rapidly growing. Even if surgical mistakes still represent one of the main causes of medico-legal issues, many disputes depend on what happens in the post-operative course. In this article we analyzed the litigation cases that occurred in our Plastic Surgery Department, the current literature about medico-legal disputes and the importance of the doctor–patient relationship. Patients and methods: The medical records of 788 post-bariatric surgeries, the post-operative complications and the related litigation cases from January 2015 to December 2019 were collected, analyzed and compared. Results: We performed 380 abdominoplasties, 28 torsoplasties, 65 breast reductions, 99 mastopexies, 94 brachioplasties, 52 thighplasties, 65 liposuctions and 5 facelifts between 2015 and 2019. Eight patients complained of medical issues and claimed for litigation. Despite in all cases the judges highlighted the risk of consent misinterpretation, the payout was granted only in one case. Conclusion: Post-bariatric patients often mistake their preoperative condition and consider body contouring procedures as an aesthetic surgery treatment. Patients should be therefore clearly informed about the complexity of body contouring procedures after massive weight loss, which should never be compared to aesthetic surgery. Surgeons should always promote the communication with their patients and build a strong and trustworthy relationship. This attitude will allow to deal more easily with complications and, in the worst situations, with medico-legal litigations.
