Cura por vacío (VAC), a propósito de un caso en Atención Primaria / Vacuum assisted closure (VAC), about a case in primary care

El síndrome compartimental agudo requiere de la descompresión quirúrgica, mediante fasciotomía, esta técnica debe ser urgente y será clave para evitar la instauración de graves secuelas. El posterior abordaje de estas heridas de difícil y lenta cicatrización suponen un reto para los profesionales de la salud y un problema para la salud pública debido a los altos costes y elevada morbilidad. La terapia de presión negativa (TPN) o cura por vacío (VAC, "vacuum assisted closure") es un tratamiento no invasivo que consigue la curación de las heridas favoreciendo la vascularización, la aparición del tejido de granulación y eliminación del exceso de exudado[AU]

Acute compartment syndrome requires surgical decompression by fasciotomy, this technique must be urgent and will be key to avoid the establishment of serious sequels. The subsequent approach to these wounds, which are difficult and slow to heal, is a challenge for health professionals and a problem for public health due to high costs and high morbidity. Negative pressure therapy (NPWT) or vacuum assisted closure (VAC) is a non-invasive treatment that achieves wound healing by promoting vascularization, the appearance of granulation tissue and elimination of excess exudate[AU]

Negative Pressure Wound Therapy After Intestinal Anastomosis: A Risk Factor Analysis for Dehiscence.

INTRODUCTION: Negative pressure wound therapy (NPWT) is part of the temporary abdominal closure in the treatment of patients with traumatic, inflammatory, or vascular disease. However, the use of NPWT when performing an intestinal anastomosis has been controversial. This study aimed to describe the patients managed with NPWT therapy and identify the risk factors for anastomotic dehiscence when intestinal anastomosis was performed. METHODS: A single-center cohort study with prospectively collected databases was performed. Patients who required NPWT therapy from January 2014 to December 2018 were included. Patients were stratified according to the performance of intestinal anastomosis and according to the presence of dehiscence. Bivariate and multivariate analyses were performed for anastomotic dehiscence and mortality. RESULTS: A total of 97 patients were included. Median age was 52 y old [interquartile range 24.5-70]. Male patients corresponded to 75.6% (n = 34) of the population. Delayed fascial closure was performed in 80% (n = 36). The risk of anastomotic dehiscence was higher in females (odds ratio (OR) 11.52 [confidence interval (CI) 1.29-97.85], P = 0.030), delayed fascial closure (OR 18.18 [CI 2.02-163.5], P = 0.010) and use of vasopressors (OR 12.04 [CI 1.22-118.47], P = 0.033). NPWT pressures >110 mmHg were evidenced in the dehiscence group with statistically significant value (OR 1.2 [0.99-2.26] p 0.04) CONCLUSIONS: There is still controversy in the use of NPWT when performing intestinal anastomosis. According to our data, the risk of dehiscence is higher in females, delayed fascial closure, use of vasopressors, and NPWT pressures >110 MMHG.

Comparison between Vacuum-Assisted Closure Technique and Conventional Approach in Patients with Mediastinitis After Isolated Coronary Artery Bypass Graft Surgery.

INTRODUCTION: Median sternotomy is the most preferred approach in heart surgery. Post-sternotomy mediastinitis is a catastrophic and potentially life-threatening complication with an incidence rate of 0.15% to 5%, and its overall mortality rate reaches 47%. In this study, we aimed to compare the results of vacuum-assisted closure technique and the conventional methods on the management of mediastinitis following isolated coronary artery bypass graft surgery. METHODS: Between February 2001 and July 2013, 32,106 patients who underwent cardiac operations were evaluated retrospectively. One hundred and fourteen patients who developed post-sternotomy mediastinitis were included in this study. The patients were divided into two groups and compared - vacuum-assisted closure group (n=52, 45.6%) and conventional treatment group (n=62, 54.4%). RESULTS: There were no differences between the two groups according to the patients' characteristics, surgical data, and mediastinal cultures. However, we found that total treatment duration for post-sternotomy mediastinitis, time interval from diagnosis to negative culture, hospitalization time, and in-hospital mortality were statistically significantly lower in the vacuum-assisted closure group than in the conventional treatment group (P<0.001, P<0.001, P<0.001, and P=0.03, respectively). CONCLUSION: This study demonstrates that the vacuum-assisted closure technique improves the medical outcome of patients with post-sternotomy mediastinitis compared with the conventional treatment. The vacuum-assisted closure is a safe and more effective treatment modality for patients with post-sternotomy mediastinitis after cardiac surgery with reasonable morbidity and mortality.

Combined use of progressive tension suture and negative pressure wound therapy in large torso degloving wounds.

OBJECTIVE: To demonstrate the associated use of progressive tension sutures (PTS) with negative pressure wound therapy (NPWT) in large torso degloving wounds. METHODS: This is a case report of two patients with large torso degloving wounds caused by trauma, both of whom were treated with combined PTS and NPWT. Statistics related to wound treatment responses are presented. RESULTS: Initial wound area for Patient 1 was 2400cm2 and 900cm2 for Patient 2. Within 21 and 12 days, respectively, using the combined method, the following data were observed: wound reduction of 94% and 99%, respectively; a closing speed rate of 98cm2/day and 75cm2/day, respectively; and a closing percentage of 4.45% per day and 8.25% per day, respectively. CONCLUSION: The use of combined PTS and NPWT techniques may be useful in the treatment of traumatic degloving injuries, reducing the wound area and facilitating reconstruction.

Endoluminal vacuum therapy in the management of an esophago-pleural fistula as a complication of Boerhaave syndrome in a patient with eosinophilic esophagitis.

BACKGROUND: Boerhaave syndrome is an uncommon condition that represents about 15% of all esophageal perforation. A subset of these patients has eosinophilic esophagitis, a chronic inflammatory disease of the esophagus, that carries a risk of perforation of about 2%. Esophageal perforations can rarely result in the development of an esophago-pleural fistula. Treatment of esophago-pleural fistula represent a challenge due to lack of high quality evidence and scarce reported experience. Endoluminal vacuum-assisted therapy could have a role in the management by using the same principle applied in external wounds which provide wound drainage and tissue granulation. CASE PRESENTATION: We report a unique case of a 24-year-old man with eosinophilic esophagitis complicated with an esophageal rupture who developed an esophago-pleural fistula and was successfully managed with a non-surgical approach using endoluminal vacuum-assisted therapy. To our knowledge this could be the first experience reported in a patient with eosinophilic esophagitis. CONCLUSION: Endoluminal vacuum-assisted therapy might be an effective and novel strategy in patients with eosinophilic esophagitis and esophago-pleural fistula as a consequence of Boerhaave syndrome. Appropriately designed studies are required.

Vacuum-assisted closure device in the postoperative wound care for Fournier's gangrene: a systematic review.

PURPOSE: To determine the effectiveness of Vacuum-Assisted Closure Device in the postoperative wound care for Fournier's gangrene METHODS: We performed a systematic review in the following databases: Medline (Ovid), EMBASE, and The Cochrane Central Register of Controlled Trials (CENTRAL), from inception to nowadays. We included RCTs and analytical observational studies. Meta-analysis was not possible given the clinical and methodological heterogeneity of the studies. RESULTS: We included six studies that compared VAC treated patients and a control group. The length of stay of the VAC treated vs. the conventional dressing treated patients was higher for the VAC treated patients in all but one of the included studies. The VAC group had the highest number of surgical debridements requiring anesthesia. The conventionally treated patients had a higher number of daily dressings, and the need for additional dressing changes, without anesthesia. Two studies found significantly higher mean scores for VAS, requiring a higher need for daily analgesics for the control group patients. CONCLUSIONS: VAC therapy is an effective method, but it is not better than conventional dressing treatment. VAC carries fewer dressing changes, less pain, and less need for analgesics, but it comes with a higher need for surgical interventions requiring anesthesia.

Continuous peritoneal lavage with vacuum peritoneostomy: an experimental study

OBJECTIVE: Despite advances in diffuse peritonitis treatment protocols, some cases develop unfavorably. With the advent of vacuum therapy, the use of laparostomy to treat peritonitis has gained traction. Another treatment modality is continuous peritoneal lavage. However, maintaining this technique is difficult and has been associated with controversial results. We propose a new model of continuous peritoneal lavage that takes advantage of the features and benefits of vacuum laparostomy. METHOD: Pigs (Landrace and Large White) under general anesthesia were submitted to laparostomy through which a multiperforated tube was placed along each flank and exteriorized in the left and lower right quadrants. A vacuum dressing was applied, and intermittent negative pressure was maintained. Peritoneal dialysis solution (PDS) was then infused through the tubes for 36 hours. The stability of peritoneostomy with intermittent infusion of fluids, the system resistance to obstruction and leakage, water balance, hemodynamic and biochemical parameters were evaluated. Fluid disposition in the abdominal cavity was analyzed through CT. RESULTS: Even when negative pressure was not applied, the dressing maintained the integrity of the system, and there were no leaks or blockage of the catheters during the procedure. The aspirated volume by vacuum laparostomy was similar to the infused volume (9073.5±1496.35 mL versus 10165±235.73 mL, p=0.25), and there were no major changes in hemodynamic or biochemical analysis. According to CT images, 60 ml/kg PDS was sufficient to occupy all intra-abdominal spaces. CONCLUSION: Continuous peritoneal lavage with negative pressure proved to be technically possible and may be an option in the treatment of diffuse peritonitis.

[Impact of vacuum-assisted closure management in deep neck abscesses]. / Impacto del manejo con cierre asistido al vacío en abscesos profundos de cuello.

BACKGROUND: The presence of deep neck abscesses is potentially serious; they can lead to death in a short period of time. The vacuum-assisted closure (V.A.C.) therapy has been used in many areas of surgery for complex wound healing. This treatment modality has recently been considered in the field of head and neck surgery. OBJECTIVE: Evaluate the efficacy of healing therapy using V.A.C. therapy in deep neck abscesses. MATERIAL AND METHODS: Open-label trial. Patients with deep neck abscesses were included using V.A.C. therapy versus conventional therapy. Cultures were taken before and during surgery, and prior to primary wound closure. The percentages of healing, viable tissue, wound healing time, and hospital stay were evaluated. RESULTS: A total of 18 patients were included. Affected neck spaces: submaxilar 29%, parapharyngeal 22%, submental 21% and masticatory 13%. The final postsurgical culture was negative in 78%. Viable tissue of the wound for the V.A.C. group was 42%, and for the control group was 36% (p=0.025). Healing time was 22±6 days and 38±15.5, respectively (p = 0.01). The mean number of hospital stay was 12 days for both groups. CONCLUSIONS: Therapy with V.A.C. is useful in the treatment of deep neck abscesses; it decreased healing time as a result of more viable tissue allowing suture closure of the wound in a shorter period.

Cierre asistido con presión negativa VAC, en el tratamiento de esternotomía infectada: primer caso en Latinoamérica / Vacuum assisted closure (VAC), in the treatment of infected sternotomy: first case in Latinamerica

Una nueva técnica utilizando el cierre asistido con vacío o presión negativa (VAC, por sus siglas en inglés) se utilizó exitosamente en un paciente masculino de 57 años, con una herida de esternotomía dehiscente e infectada. Posterior a su desbridamiento y drenaje de absceso, el tratamiento regular con gasa iodoformada que utilizó por 10 días, fue sustituido con la aplicación de presión negativa con succión controlada durante 7 días. Esta novedosa técnica, para el cierre deheridas, utilizada por primera vez en Latinoamérica, en este tipo de lesión, hizo posible reducir el tiempo de cicatrización y los costos hospitalarios inherentes a este tipo de complicación.

A new technique using vacuum assisted closure (VAC) was succesfully applied to a 57 year old, male patient, with a dehisced infected sternotomy wound. After debridment and abscess drainage, a standard treatment with iodorform gauze strip was applied during 10 days, then it was substituted with by the application of negative pressure by controlled suction through a porous derssing, during 7 days. This novel technique, the first time applied in Latinamerica in this kind of lesion, has made possible to reduce healing time and hospital costs.
