RESUMO
BACKGROUND: Open abdomen is an alternative for the management of trauma patient, and negative pressure therapy of the wound using VAC® device is a genuine sort of treatment. Although the device poses technical advantages, risks are present and a critical complication is the enteroatmospheric fistula formation (EAF). OBJECTIVE: To analize the role of negative pressure therapy length and VAC® device number of changes on the EAF formation in trauma patients udergoing open abdomen. METHOD: Cut-off points were calculated using receiver operational characteristics curve. Values were compared with Student's t or Mann-Withney U tests, considering statistically significant p < 0.05. RESULTS: EAF were present in 39 cases (5.9%). A significant difference in the presence of EAF was present in patients with negative pressure therapy of the wound length ≥ 11.2 days (46.9 vs. 1.3%; relative risk [RR]: 3.67; 95% confidence interval [95% IC]: 2.4-6.68; p = 0.017) and when ≥ 2.6 VAC® device changes were performed (34.6 vs. 0.5%; RR: 6.92; 95% IC: 1.1-4.3; p < 0.001). CONCLUSIONS: At our institution, the practice of >3 VAC® device changes and length of therapy > 11 days should be carefully considered leading to reduce the risk of EAF formation.
INTRODUCCIÓN: El abdomen abierto es una alternativa para manejar al paciente traumatizado, y una variante para instituirlo es la terapia de presión negativa de la herida con el dispositivo VAC®. Aunque tiene ventajas técnicas, no está exento de riesgos y una complicación crítica es la formación de fístulas enteroatmosféricas (FEA). OBJETIVO: Analizar el papel de la duración de la terapia de presión negativa y del número de cambios del dispositivo VAC® sobre la aparición de FEA en pacientes traumatizados manejados con abdomen abierto. MÉTODO: Se establecieron puntos de corte con curva de características operacionales del receptor. Los valores se compararon con la prueba t de Student o U de Mann-Whitney, considerando p < 0.05 como valor estadísticamente significativo. RESULTADOS: La FEA se presentó en 39 casos (5.9%). Hubo una diferencia significativa en la aparición de FEA en pacientes con duración de la terapia de presión negativa de la herida ≥ 11.2 días (46.9 vs 1.3%; riesgo relativo [RR]: 3.67; intervalo de confianza del 95% [IC95%]: 2.4-6.68; p = 0.017) y cuando se practicaron ≥ 2.6 cambios del dispositivo VAC® (34.6 vs. 0.5%; RR: 6.92; IC95%: 1.1-4.3; p < 0.001). CONCLUSIONES: En nuestra institución, la práctica de más de tres cambios del dispositivo VAC® y el mantenimiento de la terapia por más de 11 días debe ser cuidadosamente considerado para reducir el riesgo de formación de FEA.

Introducción: Las mordeduras por araña parda pueden manifestarse desde una simple lesión dérmica en el área de la mordedura, hasta formas graves, con falla orgánica múltiple. Caso Clínico: presentamos el caso de una paciente con mordedura por araña parda, quien presenta inicialmente lesiones dérmicas sin necrosis, evolucionando con áreas de necrosis y el desarrollo de síndrome compartimental de extremidad, sepsis, choque séptico y falla renal. Mejora tras manejo intensivo, anti veneno y colocación de terapia de presión negativa (TPN) en herida, conservando la extremidad afectada integra y recuperando la función renal. Discusion: Este caso en particular presenta los tres tipos de manifestaciones que se generan en el loxoscelismo, las cuales son una forma de presentación poco frecuente. El tratamiento con TPN se ha introducido como una terapia poderosa, no farmacológica para ayudar a acelerar el proceso de cicatrización de heridas y puede ser de utilidad en pacientes con mordedura de araña (loxoscelismo).
Introduction: The brown spider bites have the peculiarity of manifesting from a simple skin lesion in the area of the bite, to severe forms, with multiple organic failure. Clinical Case: We present the case of a patient with a brown spider bite, initially presenting dermal lesions without necrosis, evolving with areas of necrosis and the development of compartment syndrome of extremities, sepsis, septic shock and renal failure. Improvement after intensive management and installation in negative pressure therapy wound (NPT), keeping the affected limb integrated and recovering renal function. Discussion: This case in particular presents the three types of manifestations that are generated in loxoscelism, which are a rare form of presentation. The NPT treatment has been introduced as a powerful, non-pharmacological and physical therapy to help accelerate the wound healing process and may be useful in patients with spider bites.

Pyoderma gangrenosum (PG) is a rare painful ulcerative neutrophilic inflammatory skin disease, necessitating a high level of diagnostic suspicion associated with appropriate treatment to avoid progression. Negative pressure wound therapy (NPWT) has been efficiently used in the treatment of different types of wounds. However, the role of NPWT in the management of PG is still controversial, due to the risk of the pathergy phenomenon. In this article, we conducted a systematic review (according to the PRISMA guidelines) on the use of NPWT in the treatment of PG, and we report our personal experience with two patients treated with this device. The result of the review showed that articles on the topic are, in their entirety, of low levels of evidence, such as case series, case reports, and reviews. Improvement in wound healing with the use of NPWT was observed in 85.1% of the patients studied. Besides, a significant association between improvement in wound healing with NPWT and immunosuppressive therapy was observed. Regarding the cases reported here, both showed good outcomes with the use of NPWT and skin graft during the treatment of PG injuries. Due to the rarity of PG, there is a scarcity of studies with robust evidence for standardization and comparison between treatments, which consequently makes it difficult to select therapeutic options. However, based on this systematic review and reported cases, we consider NPWT a safe option for adjuvant treatment of wounds caused by PG if combined with systemic immunosuppression, which plays a key role in greater chances of successful treatment. This approach should be recommended, whenever possible, associated with skin grafting to accelerate wound closure. The role of negative pressure wound therapy (NPWT) on the treatment of pyoderma gangrenosum: a systematic review and personal experience.

This study presents a novel technique for the treatment of a deep esophageal ulcer after ablation of paroxysmal atrial fibrillation (AF). Pulmonary vein isolation was performed using a radiofrequency irrigated tip catheter. On Day 5 of follow-up, a deep esophageal ulcer was observed. No significant visual improvement was observed after conventional treatment. Endoscopic negative pressure therapy in the esophagus was then applied for 5 days. A significant decrease in diameter and depth of the lesion was observed, possibly preventing perforation. Endoscopic negative pressure therapy can be used to heal thermal lesions after AF ablation procedures.

BACKGROUND: Many commercial and artisanal devices are utilized for temporary abdominal closure in patients being managed with an open abdomen for abdominal sepsis. The costs of materials required to treat patients with an open abdomen varies drastically. In Costa Rica, due to the lack of accurate information relating to the actual cost to manage a patient entails that the method with the least expensive materials is usually selected. STUDY DESIGN: A single-center retrospective review of 46 patients diagnosed with abdominal sepsis and successfully treated with an open abdomen and one of the three temporary abdominal closure methods during the year 2018 in a tertiary hospital was evaluated using a gross-cost pricing model developed by the authors. The three temporary abdominal closure methods were a locally manufactured Bogota Bag, and commercial abdominal negative pressure therapy dressing and negative pressure therapy with 0.9% saline solution instillation. The per-unit-costs were hospital day and intensive care day, number of surgical procedures per patient, cost negative pressure therapy kits. RESULTS: Statistically significant cost reduction was observed in the cohort treated with negative pressure therapy with instillation as compared to the other temporary abdominal closure methods. The reduction of hospital length of stay, as well as fewer number of surgeries were the main contributing factors in diminishing costs. On average, the costs to treat a patient utilizing negative pressure therapy with instillation was nearly 50% lower than using the other two temporary abdominal closure methods. CONCLUSIONS: The costs relating to managing abdominal sepsis in the septic open abdomen vary greatly according to the temporary abdominal closure utilized. If the hospital length of stay, intensive care unit length of stay and number of surgeries required are the main parameters used in determining costs, the use of negative pressure therapy with 0.9% saline solution instillation reduces costs by nearly 50% in comparison to conventional negative pressure wound therapy and Bogota Bag. In this instance, the more expensive method at first glance, obtained a considerable cost reduction when compared to therapies that utilize less expensive materials.
RESUMO
BACKGROUND: Acute pancreatitis represents one of the most frequent digestive pathologies worldwide, which can be complicated as an infected necrotizing acute pancreatitis, that may require treatment with necrosectomy and open abdomen with the risk that this leads to the appearance of intestinal fistula and giant incisional hernias difficult to manage. CLINICAL CASE: A 35-year-old woman underwent laparoscopic cholecystectomy for acute cholecystitis, which was re-admitted due to jaundice and abdominal pain 3 days after her hospital discharge. Diagnostic laparoscopy is performed, where a 3200 cc biliperitoneum secondary to a cystic duct stump leak is located and drained. Likewise, an endoscopic retrograde cholangiopancreatography (ERCP) is performed, with extraction of an impacted bile gallstone in the distal common bile duct. It presents as a complication of the procedure an acute post-ERCP pancreatitis with infected pancreatic necrosis. Open pancreatic necrosectomy was performed with a negative pressure therapy and mesh-mediated fascial traction, achieving resolution of the infectious condition with definitive closure of the abdominal cavity without incisional hernia or postoperative intestinal fistula. CONCLUSION: Patients with complicated acute pancreatitis with infected pancreatic necrosis represent a challenge in their treatment due to the serious nature of the condition and the morbidity associated with it. A therapeutic option is presented with the combined use of negative pressure therapy (ABThera™) and mesh-mediated fascial traction. With this report we propose a potential line of research to determine its role in the treatment of these patients, as well as their possible advantages and complications.
ANTECEDENTES: La pancreatitis aguda representa una de las enfermedades digestivas más frecuentes en todo el mundo, la cual puede complicarse como una pancreatitis aguda necrotizante infectada, que puede necesitar tratamiento con necrosectomía y abdomen abierto, con el riesgo que esto conlleva de aparición de fistula intestinal y hernias incisionales gigantes de difícil tratamiento. CASO CLÍNICO: Mujer de 35 años, intervenida de colecistectomía laparoscópica por colecistitis aguda, que es reingresada por ictericia y dolor abdominal 3 días después de su egreso hospitalario. Se realiza laparoscopia diagnóstica, en la que se encuentra y drena un biliperitoneo de 3200 cc secundario a una fuga de muñón del conducto cístico. Así mismo, se practica una colangiopancreatografía retrógrada endoscópica (CPRE), con extracción de un lito biliar impactado en el colédoco distal. Presenta como complicación del procedimiento pancreatitis aguda tras la CPRE con necrosis pancreática infectada. Se realiza necrosectomía pancreática abierta con sistema de presión negativa y tracción fascial mediante malla, logrando la resolución del cuadro infeccioso con cierre definitivo de la cavidad abdominal sin presentar hernia incisional ni fistula intestinal posoperatoria. CONCLUSIÓN: Los pacientes con pancreatitis aguda complicada con necrosis pancreática infectada representan un reto en su tratamiento por la naturaleza grave del padecimiento y la morbilidad asociada. Se presenta una opción terapéutica con el uso combinado de presión negativa (ABThera™) y tracción fascial mediante malla. Con el presente reporte se propone una potencial línea de investigación para determinar su papel en el tratamiento de estos pacientes, así como sus posibles ventajas y complicaciones.

OBJECTIVE: Vascular groin incision complications contribute significantly to patients' morbidity and rising health care costs. Negative pressure therapy over the closed incision decreases the infection rate in cardiac and orthopedic procedures. This study prospectively evaluated negative pressure therapy as a means to decrease wound complications and associated health care costs. METHODS: This was a randomized, prospective, single-institution study of 119 femoral incisions closed primarily after elective vascular surgery including both inflow (eg, aortofemoral) and outflow (eg, femoral-popliteal bypass) procedures. Incisions were categorized as high risk for wound complications on the basis of body mass index >30 kg/m2, pannus, reoperation, prosthetic graft, poor nutrition, immunosuppression, or hemoglobin A1c >8% and randomized 1:1 to standard gauze (n = 60) dressing vs negative pressure therapy (Prevena [Acelity, San Antonio, Tex], n = 59). Wound complication rate, length of stay (LOS), reoperation, readmission, and variable hospital costs were determined during 30 days. Statistical analysis was performed using χ2 test along with a two-sample unpaired t-test for continuous variables. RESULTS: There were no significant demographic differences (age, sex, risk factors for wound complication) between the two high-risk groups. In low-risk controls, the major wound complication rate was 4.8% (involving one infection in 21 incisions), resulting in a 3.8-day LOS, 4.8% reoperation, 4.8% readmission rate, and $17,599 in average variable cost. For high-risk controls, there was a significant increase in major wound complications to 25% (including all 12 infections in 60 incisions), LOS (10.6 days), reoperation (18.3%), readmission (16.7%), and costs ($36,537). Finally, negative pressure therapy significantly reduced major wound complications to 8.5% (including five of six infections in 59 incisions; P < .001), reoperation (8.5%; P < .05), and readmission (6.8%; P < .04) but not LOS (10.6 days). The average variable cost was reduced ($30,492), yielding an average savings of $6045 per patient (P = .11). CONCLUSIONS: This study suggests that negative pressure therapy significantly reduces the major wound complication, reoperation, and readmission rates for patients at high risk for groin wound complications. Furthermore, this therapy may lead to a reduction in hospital costs. Negative pressure therapy for all groin incisions considered at high risk for wound complications is recommended.

Na última década multiplicaram-se as publicações e a utilização da cirurgia de controle de danos, resultando num número crescente de pacientes deixados com o abdome aberto (ou peritoneostomia). Uma das consequências nefastas do abdome aberto são as hérnias ventrais gigantes que resultam da impossibilidade de se fechar o abdome durante a internação hospitalar do paciente. Para minimizar esta sequela têm surgido na literatura diferentes tipos de abordagem. Para abordar este tópico, a reunião de revista "Telemedicina Baseada em Evidência - Cirurgia do Trauma e Emergência" (TBE-CiTE) optou por não analisar sistemas comerciais de fechamento abdominal dinâmico, com exceção da terapia de pressão negativa ou vácuo. O grupo fez uma avaliação crítica dirigida de três artigos mais relevantes publicados recentemente sobre fechamento sequencial da parede abdominal (com tela ou sutura) mais vácuo. Nesta avaliação foram incluídos dois estudos retrospectivos mais um estudo prospectivo. Baseados na análise crítica desses 3 estudos mais a discussão que contou com a participação de representantes de 6 Universidades e realizada via telemedicina, são feitas as seguintes recomendações: (1) a associação de terapia de pressão negativa com tração fascial constante mediada por tela ou sutura, ajustada periodicamente, parece ser uma ótima estratégia cirúrgica para o tratamento de peritoneostomias. (2) O fechamento abdominal primário dinâmico com sutura e mediada por tela parece ser mais econômico e eficiente do que deixar o paciente com uma hérnia gigante e planejar uma reconstrução complexa tardiamente. Novos estudos com grupos maiores de pacientes separados de acordo com as diferentes apresentações e doenças são necesários para definir qual o melhor método cirúrgico para o tratamento de peritoneostomias.
The last decade was marked by a multiplication in the number of publications on (and usage of) the concept of damage control laparotomy, resulting in a growing number of patients left with an open abdomen (or peritoneostomy). Gigantic hernias are among the dreaded consequences of damage control and the impossibility of closing the abdomen during the initial hospital admission. To minimize this sequela, the literature has proposed many different strategies. In order to explore this topic, the "Evidence-based Telemedicine - Trauma & Acute Care Surgery" (EBT -TACS) conducted a literature review and critically appraised the most relevant articles on the topic. No commercially available systems for the closure of peritoneostomies were analyzed, except for negative pressure therapy. Three relevant and recently published studies on the sequential closure of the abdominal wall (with mesh or sutures) plus negative pressure therapy were appraised. For this appraisal 2 retrospective and one prospective study were included. The EBT-TACS meeting was attended by representatives of 6 Universities and following recommendations were generated: (1) the association of negative pressure therapy and continuous fascia traction with mesh or suture and adjusted periodically appears to be a viable surgical strategy to treat peritoneostomies. (2) the primary dynamic abdominal closure with sutures or mesh appears to be more efficient and economically sound than leaving the patient with a gigantic hernia to undergo complex repair at a later date. New studies including larger number of patients classified according to their different presentations and diseases are needed to better define the best surgical treatment for patients with peritoneostomies.
