NPWTi proves to be an efficient treatment option for abdominal wall wound dehiscence with mesh exposure, compared to CWT. More trials aimed to optimize treatment protocols will lead to an additional increase in NPWTi efficiency. In addition, to generalize our results, further studies with larger samples would be necessary.
BackgroundIn the practice of breast augmentation and reconstruction, implant irrigation with various solutions has been widely used to prevent infection and capsular contracture, but to date, there is no consensus on the optimal protocol to use. Recently, application of povidone iodine (PI) for 30 min has shown in vitro to be the most effective irrigating formula in reducing contamination in smooth breast implants. However, as 30 min is not feasible intraoperatively, it is necessary to determine whether shorter times could be equally effective as well as to test it in both smooth and textured implants.MethodsWe tested the efficacy of 10% PI at 1′, 3′, and 5′ against biofilms of 8 strains (2 ATCC and 6 clinical) of Staphylococcus spp. on silicone disks obtained from Mentor® and Polytech® implants of different textures. We analyzed the percentage reduction of cfu counts, cell viability and bacterial density between treatment (PI) and control (sterile saline, SS) groups for each time of application. We consider clinical significance when > 25% reduction was observed in cell viability or bacterial density.ResultsAll textured implants treated with PI at any of the 3 exposure times reduced 100% bacterial load by culture. However, none of the implants reached enough clinical significance in percentage reduction of living cells. Regarding bacterial density, only 25–50 μm Polytxt® Polytech® implants showed significant reduction at the three PI exposure times.ConclusionPI is able to inhibit bacterial growth applied on the surface of breast implants regardless of the exposure time. However, no significant reduction on living cells or bacterial density was observed. This lack of correlation may be caused by differences in texture that directly affect PI absorption.
Background: Pyoderma gangrenosum (PG) is a rare cutaneous ulcerative disease that does not respond to antibiotics and worsens with surgical manipulation. This is the first report in the literature revealing that this disease complicates total microsurgical breast reconstruction associated with the transfer of free lymph nodes. Case Report: We report the case of a female patient who underwent left-breast microsurgical reconstruction with a deep inferior epigastric perforator (DIEP) flap and simultaneous transfer of vascularized free lymph nodes for the surgical treatment of secondary left upper-limb lymphedema, and who developed a severe PG of both the skin of the flap and the donor zone on postoperative day 7. After exclusion of other etiologies, treatment with high-dose corticosteroids and topical zinc sulfate was initiated. The flap was salvaged and breast cancer-related lymphedema (BCRL) surgery was definitively effective despite the PG. Conclusions: PG should be considered in the differential diagnosis of progressive cutaneous ulcers following surgical interventions, once infectious and ischemic etiologies have been excluded. Early initiation of immunosuppressive treatment can lead to preservation of the initial flap and function of the transferred lymph nodes in the case of microsurgical breast reconstruction with associated lymph node transfer.
<b><i>Background:</i></b> Lipofilling techniques are widespread in clinical practice as a complement to breast reconstruction, despite posing some risk. Punctual implant rupture following a fat transfer is one of the possible complications, which has not been properly reported yet and is probably being underdiagnosed. The aim of this paper is to report key facts for appropriate diagnosis of this clinical chart.<i></i><b><i>Case Report:</i></b><i></i>We present the case of a 47-year-old woman with a bilateral prosthetic breast reconstruction who was treated with autologous fat graft for upper pole enhancing and scar improvement. The patient developed an early unilateral breast capsular contracture after the fat graft procedure, with normal radiological exploration. Surgical findings showed intraprosthetic fat deposits and a punctual implant rupture. <b><i>Conclusions:</i></b> Punctual breast implant rupture is a possible complication of lipofilling that is usually not suspected at first consultation and might be underdiagnosed based on radiological findings, so investigating clinical signs should necessarily be a prerequisite to diagnosis.
ResumenDescribimos nuestra experiencia en el tratamiento de heridas abdominales postquirúrgicas dehiscentes y contaminadas con exposición de material protésico, mediante terapia de presión negativa con instilación intermitente de soluciones tópicas. Este dispositivo nos permitió el rescate de pacientes pluripatológicos evitando una reintervención compleja de alta morbi-mortalidad y facilitando el cierre de la herida, además con conservación de la malla en la mayor parte de los casos.

AbstractThe present data reports our experience in the treatment of postsurgical dehiscent and infected abdominal wounds with exposure of prosthetic material with negative pressure therapy with intermittent instillation of topical solutions. This device allowed the rescue of pluripatological patients avoiding a complex resurgery of high morbi-mortality and facilitating wound closure, besides with conservation of the mesh in most of the cases.
