RESUMO
INTRODUCTION: Breast reconstruction (BR) using a prosthesis implant (PI) associated with an acellular dermal matrix (ADM) is a known method that has been the subject of discussion in recent years. The objective of this study was to quantify the rate of PI removal after BR using prosthesis combined with ADM, and to identify the risk factors in the event of removal. METHODS: This was a retrospective study conducted between 2010 and 2015. Inclusion criteria were patients who had undergone immediate (IBR) or delayed (DBR) breast reconstruction with placement of a PI associated with porcine ADM. The primary endpoint was the postoperative removal of the PI. RESULTS: In all, 84 reconstructions were performed. The mean age of the population was 57.5 years. 25.9% of the patients were active smokers at the time of surgery. 89.5% of patients had previously benefited from ipsilateral breast radiation therapy (IBRT) in DBR, 10.5% in IBR. The PI deposition rate, all BR combined, was 21.4%. It was 52.17% in smokers and 9.84% in non-smokers (P<0.0001), making smoking an independent risk factor for reconstruction failure (hazard ratio (HR)=7.4, 95%CI [2.64-20.9]). IBRT was also a risk factor for PI removal, especially when performed after IBR (HR=8.1, 95%CI [1.1-62.1]). CONCLUSION: Smoking and adjuvant IBRT are risk factors for failure of reconstruction by PI associated with ADM. This type of reconstruction should be selected for non-smokers who have not undergone IBRT and therefore could be a therapeutic alternative in the BR panel.

Negative Pressure Wound Therapy is a device applied to a wound that causes local depression. There are a few series showing the effectiveness of this treatment in Pediatric. The objective of this work is to try to clarify the indications in children. This is a retrospective series of 25 children between 2004 and 2019. The inclusion criteria were all children with a wound treated with Negative Pressure Wound Therapy. The characteristics retained were their age, the context of occurrence, the treatment time, the depression applied, the technique of skin covering wound and the average healing time. We included 25 patients. The average age was 8.8 years. The context of the wound occurrence was mainly a road (44%) or a domestic (36%) accident. Substance losses were mainly located in the lower limb (84%). The depression applied was -90mmHg. The healing time was 18.4 days. Thin skin grafting was the main method chosen (88%). No complications related to Negative Pressure Wound Therapy equipment have been identified. Despite the weakness of the literature and the lack of consensus regarding its use, Negative Pressure Wound Therapy is an essential therapy in pediatric. It is a simple and effective technique in children. It can reduce the need for flaps coverage, even in the event of exposure of noble elements. The flaps should not, however, be excluded from the decision-making algorithm, on pain of complications or sequelae.

Loss of tissue substance in children's limbs has the same etiologies and in many cases, the same severity as in adults' limbs, and the means placed at the disposal of a surgeon are likewise comparable. It may nonetheless prove difficult to strategically position the different treatment methods in a decision-making tree. After all, a child presents numerous peculiarities: high quality of vascularization (both microcirculation and macrocirculation), better ability to achieve nerve regeneration and durable bone consolidation and, last but not least, a pronouncedly superior overall functional prognosis. Moreover, a child's future needs to be taken into account ; it is not only cicatrization per se, but also the quality of healing that should dictate therapeutic choices, which will consequently be determined in view of avoiding functional disorders during the growth process. On the basis of their experience and following a review of the literature, the authors have assessed the interest of each relevant technique and drawn up a decision-making tree.

Surgical treatment of large and multiple lesions of irradiated scalp may require subtotal scalp exeresis and reconstruction in two-stage free flap surgery: harvesting and placing the flap first, then scalp removing and defect covering in a second step. This strategy raises the question of how to care the flap between the two surgeries. We report an original technique of free latissimus dorsi flap lacing. A 70-year-old male, afflicted with familial cylindromatosis and treated by brachytherapy 18years ago, received a free latissimus dorsi myocutaneous flap in two-stage surgery, allowing 25×25cm pathological scalp exeresis. During first step, suture clips were fixed in two rows around the future scalp defect, in order to be used as anchors for the flap lacing. Braided wire were chosen for a better steerability, and to prevent knots untightening. Thus, the flap were placed in "anatomical" place, next to the scalp, pending secondary procedure. This situation permitted to avoid flap or pedicle compression or plication, and to ease flap care. The wires were tighten as shoelaces, allowing them to be undone and done as desired. The two-stage free latissimus dorsi flap reconstruction of scalp large defect permitted us to assess the flap reliability before final reconstruction. The lacing solution allowed us regular local care and convenient flap handling, while favoriting its optimal placing next to its future location.
