Uso de ileostomía derivativa en cáncer de ovario. Revisión de la literatura / Use of diverting ileostomy in ovarian cancer. Literature review

Introducción. La ileostomía derivativa de protección se realiza con el objetivo de proteger la anastomosis intestinal después de una resección colorrectal. Esta resección intestinal es el procedimiento extendido más frecuentemente realizado en pacientes con cáncer de ovario, con el fin de lograr una citorreducción completa. Conocer las indicaciones, el uso, las técnicas y las complicaciones de las ileostomías es importante para los grupos multidisciplinarios que tratan estas pacientes. Métodos. Se realizó una búsqueda en PubMed vía Medline y una revisión narrativa actualizada de los principales hallazgos sobre las indicaciones, las técnicas quirúrgicas, complicaciones y el uso de la ileostomía derivativa en el cáncer de ovario. Resultados. El uso de la ileostomía derivativa en cáncer de ovario sigue siendo un tema controvertido. Hasta la fecha, ni la ileostomía de derivación ni la ileostomía fantasma se han asociado con una reducción en la incidencia de la fuga anastomótica, pero ambas técnicas podrían disminuir su gravedad. Conclusión. La ileostomía de derivación en cáncer de ovario se usa para proteger una anastomosis distal tras una resección intestinal, en caso de fuga anastomótica si no se ha realizado una ostomía previa o en caso de obstrucción intestinal.

Introduction. Protective diverting ileostomy is performed with the aim of protecting the intestinal anastomosis after a colorectal resection. This intestinal resection is the most frequently performed extended procedure in patients with ovarian cancer, in order to achieve complete cytoreduction. Knowing the indications, use, techniques and complications of ileostomies is important for multidisciplinary groups that treat these patients. Methods. We conducted a search in PubMed via Medline and an updated narrative review of the main findings on the indications, surgical techniques, complications and use of diverting ileostomy in ovarian cancer. Results. The use of diverting ileostomy in ovarian cancer remains a controversial issue. To date, neither diverting ileostomy nor ghost ileostomy have been associated with a reduction in the incidence of anastomotic leak, but both techniques could decrease its severity. Conclusion. The diverting ileostomy in ovarian cancer is used to protect a distal anastomosis after intestinal resection, in case of anastomotic leak if a previous ostomy has not been performed or in case of intestinal obstruction.

Sutura em Polia Retificada para síntese de feridas de pele tensionadas / Rectified Pulley Suture for the synthesis of tensioned skin wounds

Introdução: A síntese de feridas de pele tensionadas é uma área que tem sido alvo de estudos para o desenvolvimento de técnicas de sutura que sejam capazes de realizar o fechamento primário dessas feridas com alívio de tensão, garantindo uma cicatrização adequada e evitando complicações como deiscência, edema, sangramento e infecção. Método: Esta pesquisa tratou-se de um estudo piloto, sendo a primeira apresentação da técnica de Sutura em Polia Retificada para síntese de feridas de pele tensionadas através do acompanhamento prospectivo, duplo-cego, de uma série de casos de 8 pacientes randomicamente admitidos no centro cirúrgico de um hospital de alta complexidade de uma cidade de médio porte. Resultados: A Sutura em Polia Retificada é uma técnica versátil e apta para lidar com feridas de pele tensionadas, uma vez que no intraoperatório conseguiu fechar por primeira intenção lesões de até 6,5 centímetros e de diferentes regiões tensionadas sem necessidade do uso de técnicas mais complexas, como retalhos, enxertos, zetaplastia e fechamento por segunda intenção. Além disso, no pós-operatório, houve redução dos escores da POSAS, indicando um processo de cicatrização satisfatório tanto para os observadores quanto para o paciente. É imprescindível mencionar, também, que o desfecho mais temido no seguimento dos pacientes com feridas tensionadas submetidos a fechamento primário - a deiscência - foi completamente evitado. Conclusão: A técnica é simples, confiável, segura e reprodutível, com curta curva de aprendizagem, de forma que a Sutura em Polia Retificada pode ser considerada como uma nova ferramenta a ser integrada ao arsenal cirúrgico.

Introduction: The synthesis of tensioned skin wounds is an area that has been the subject of studies for the development of suturing techniques that are capable of performing the primary closure of these wounds with tension relief, ensuring adequate healing, and avoiding complications such as dehiscence, edema, bleeding, and infection. Method: This research was a pilot study, being the first presentation of the Rectified Pulley Suture technique for the synthesis of tensioned skin wounds through prospective, double-blind monitoring of a series of cases of 8 patients randomly admitted to the surgical center of a high-complexity hospital in a mediumsized city. Results: Rectified Pulley Suture is a versatile technique suitable for dealing with tensioned skin wounds, since intraoperatively it was able to close, by first intention, lesions measuring up to 6.5 centimeters and in different tensioned regions without the need for the use of more extensive techniques. complex, such as flaps, grafts, Z-plasty, and secondary intention closure. Furthermore, post-operatively, there was a reduction in POSAS scores, indicating a satisfactory healing process for both observers and the patient. It is also essential to mention that the most feared outcome in the follow-up of patients with tension wounds undergoing primary closure - dehiscence - was completely avoided. Conclusion: The technique is simple, reliable, safe, and reproducible, with a short learning curve, so the Rectified Pulley Suture can be considered a new tool to be integrated into the surgical arsenal.

Results of prophylactic simple fasciocutaneous advancement in the initial management of acute ankle fractures with high risk of operative wound complication.

Ankle fracture is the third most prevalent fracture in older adults. Wound dehiscence is the most frequent complication. Our objective is to determine the operative wound complication rate in patients with unstable ankle fracture in whom a prophylactic simple fasciocutaneous advancement was used. METHODS: Prospective registry of patients with unstable ankle fracture, in whom a prophylactic fasciocutaneous advancement was performed between August 2020 and July 2021. Demographic variables, time spent in performing the flap, cost of osteosynthesis, minor and major complications of the surgical wound, readmission or reoperation were registered. RESULTS: 42 older adults with ankle fracture were included. Median age 69 (60-94). 31% diabetics and 21.5% active smokers. A 40% trimalleolar fracture pattern. There were 7% of superficial complications of the surgical wound. No major complications, no reoperations. CONCLUSIONS: Prophylactic fasciocutaneous advancement at the beginning of traumatological surgery is technically simple, reproducible, cheap and with low complications. LEVEL OF EVIDENCE: Level IV, cross-sectional study.

Sternal dehiscence, a reconstructive challenge. Case report.

INTRODUCTION AND IMPORTANCE: Sternotomy is the main surgical procedure used to access the heart and great vessels. Among its most important complications is post-sternotomy dehiscence with an incidence of 10 %; the main risk factors for its occurrence are diabetes mellitus, obesity or chronic obstructive pulmonary disease. CASE PRESENTATION: We present a clinical case of a 74-year-old male patient with sternal dehiscence secondary to sternotomy for myocardial revascularisation. CLINICAL DISCUSSION AND CONCLUSIONS: Surgical dehiscence of sternotomy presents remarkable complexity and poses a significant challenge to the medical team. The therapeutic approach focuses on addressing the infection, removing the necrotic tissue and then covering the area with highly vascularised tissue. Surgical alternatives include the possibility of using a unilateral pectoralis muscle flap, an option that provides adequate sternal stability and leads to satisfactory functional and cosmetic results.

Terapia E-VAC como tratamiento de complicaciones en cirugía gastrointestinal en centro de referencia de gastroenterología en Colombia: Serie de casos

Las fístulas y dehiscencias anastomóticas postoperatorias gastrointestinales se presentan de forma frecuente y muchas son manejadas quirúrgicamente, sin embargo, las intervenciones endoscópicas han mostrado mejorar desenlaces de curación y tiempo de estancia hospitalaria. Se describe la experiencia de la terapia de cierre asistida por vacío (E-VAC), en el manejo de fístulas y dehiscencias anastomóticas postoperatorias, en un centro de referencia gastrointestinal en Colombia. Se realizó un estudio serie de casos en pacientes con dehiscencia de anastomosis y fístula a diferentes niveles del tracto digestivo, tratados mediante E-VAC, por el servicio de gastroenterología de la clínica universitaria Colombia, en Bogotá, durante un periodo comprendido de febrero 2019 y noviembre 2021. Se describieron variables sociodemográficas, clínicas y quirúrgicas. Se describen 6 casos, 4 de tracto digestivo inferior y 2 de tracto digestivo superior. El 83% fueron hombres, la edad media fue de 51,8 años (+/-17,5). La indicación de E-VAC fue fístula anastomótica colorrectal en el 66%, siendo la ubicación anatómica más frecuente la anastomosis colorrectal (66%), con menor frecuencia a nivel de los cardias (16%) y esófago (16%). El tamaño del defecto se describió entre el 20 y el 80% en pacientes sometidos a terapia E-VAC, siendo el tiempo promedio de hospitalización 22.5 días con un número de recambios promedio de siete por paciente. Las fugas y fístulas anastomóticas son complicaciones potencialmente mortales en pacientes llevados a intervenciones quirúrgicas gastrointestinales, en las que la terapia E-VAC ha mostrado ser eficaz y segura, promoviendo el cierre del defecto y el drenaje de colecciones presentes, igualmente disminuyendo el tiempo de estancia hospitalaria.

Gastrointestinal postoperative anastomotic leaks and fistulas occur frequently and many are managed surgically; however, endoscopic interventions have shown to improve healing outcomes and length of hospital stay. The experience of vacuum-assisted closure therapy (E-VAC) is described, in complications such as fistulasand postoperative anastomotic leaks, in a gastrointestinal reference center in Colombia. A case series study was carried out in patients with anastomotic leaks and fistulasat different levels of the digestive tract, treated by E-VAC, by the Gastroenterology Service in Colombia, during a period from February 2019 to November 2021. Sociodemographic, clinical and surgical variables were described. 6 cases are described, 4 from lower digestive tract and 2 from upper digestive tract. 83% were men; the mean age was 51.8 years (+/-17.5). The indication for E-VAC was colorectal anastomotic fistula in 66%; the most frequent anatomical location was near the anal region (66%), less frequently at the level of the cardia (16%) and esophagus (16%). The size of the defect was described between 20 and 80% in patients undergoing E-VAC therapy, with an average hospitalization length of stay of 22.5 days, with an average number of exchanges of seven per patient. Anastomotic leaks and fistulasare potentially fatal complications in gastrointestinal surgery. E-VAC therapy has shown to be effective and safe, promoting defect closure and drainage of collections present, also decreasing the length of hospital stay.

Extensor mechanism injury, infection, and an extended time between trauma and surgical approach are related to the need for total knee arthroplasty removal after traumatic dehiscence.

BACKGROUND: Surgical wound-related traumatic complications are rarely reported in the literature. Traumatic dehiscence is unpredictable because of the trauma magnitude and the potential of associated injuries. This study aims to report the clinical outcomes and complications of a case series due to traumatic dehiscence after total knee arthroplasty (TKA) and establish possible criteria for prognosis for maintaining the implant. METHODS: Patients admitted to an emergency room due to traumatic dehiscence after TKA were retrospectively evaluated. Patient data was analyzed and patients who maintained or not the arthroplasty were compared to establish prognosis factors. RESULTS: Thirty-two patients with traumatic dehiscence after TKA were evaluated. The trauma occurred on a mean of 14.3 +/- 25.0 days after the surgical procedure, and debridement in the operating room was performed on a mean of 6.2 +/- 4.9 hours after the trauma. Twenty patients maintained the arthroplasty until the end of follow-up and did not require revision. Factors related to arthroplasty removal were associated extensor mechanism injury (p = 0.026), time from trauma to surgical debridement (p = 0.035), and infection (p = 0.0001) CONCLUSION: Traumatic dehiscence after total knee arthroplasty is an event with a high rate of complications. Extensor mechanism Injury, infection, and extended time between trauma and surgical intervention were poor prognostic factors for arthroplasty maintenance.

Wound Dehiscence Following Cubital Tunnel Surgery.

PURPOSE: Cubital tunnel syndrome is the second most common upper-extremity compressive neuropathy, and persistent symptoms can necessitate operative treatment. Surgical options include simple decompression and ulnar nerve transposition. The cause of wound dehiscence after surgery is not well known, and the factors leading to the development of these complications have not been previously described. METHODS: Patients undergoing ulnar nerve surgery from January 1, 2016, to December 31, 2019, were retrospectively evaluated for the development of wound dehiscence within 3 months of surgery. There were 295 patients identified who underwent transposition and 1,106 patients who underwent simple decompression. Patient demographics and past medical history were collected to evaluate the risk factors for the development of wound dehiscence. RESULTS: The overall rate of wound dehiscence following surgery was 2.5%. In the simple decompression group, the rate of wound dehiscence was 2.7% (30/1,106), which occurred a mean of 21 days (range, 2-57 days) following surgery. In the transposition group, the rate of wound dehiscence was 1.7% (5/295), which occurred a mean of 20 days (range, 12-32 days) following surgery. The difference in rates of dehiscence between the decompression and transposition groups was not significant. Five patients in the simple decompression group and 1 patient in the transposition group required a secondary surgery for closure of the wound. Age, body mass index, smoking status, and medical comorbidities were not found to contribute to the development of wound dehiscence. CONCLUSIONS: Wound dehiscence can occur following both simple decompression and transposition, even after postoperative evaluation demonstrates a healed wound. Surgeons should be aware of this possibility and specifically counsel patients about remaining cautious with, and protective of, their wound for several weeks after surgery. Dehiscence may be related to suboptimal vascularity in the soft tissue envelope in the posteromedial elbow. When it occurs, dehiscence can generally be treated by allowing healing by secondary intention. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

A utilização da moxabustão como terapia na cicatrização por segunda intenção em cães: Relato de dois casos / The use of moxibustion as a healing therapy by secondary intention in dogs: report of two cases

A terapia com moxabustão envolve combustão de uma mistura de ervas, composta predominantemente por Artemisia vulgaris. Pode ser aplicada em diversas patologias sendo de grande utilidade para cicatrização de tecidos. O objetivo deste artigo foi abordar o uso da moxabustão em dois cães com feridas contaminadas, em que os tratamentos foram destinados a promover a cicatrização por segunda intenção. É descrito o caso de uma cadela da raça pastor-alemão com deiscência de pontos (caso 1) e o de uma cadela sem raça definida com ferida traumática por mordedura (caso 2). Nos dois casos, o tratamento com a moxabustão, modalidade da Medicina Tradicional Chinesa (MTC), foi efetivo no tratamento das feridas por segunda intenção, melhorando os aspectos de oxigenação, circulação e revitalização de tecidos. Após dois anos no caso 1, o tecido apresenta-se pigmentado e alopécico; no caso 2, a epiderme encontra-se queratinizada, uniforme e com presença de pelos, em menor dimensão há tecido pigmentado.(AU)

Moxibustion therapy involves burning a mixture of herbs, consisting predominantly of Artemisia vulgaris. It can be applied in several pathologies and is very useful for tissue healing. The aim of this article was to present the use of Moxibustion in two dogs with contaminated wounds, whose treatment aimed to achieve healing by second intention. It is presented the case of a German Shepherd dog with dehiscence of points (case 1) and one of a mixed breed dog with traumatic wound by bite (case 2). In both cases, the treatment with Moxibustion, a modality of Traditional Chinese Veterinary Medicine, demonstrated effectiveness in the treatment of wounds by secondary intention, improving aspects of oxygenation, circulation and tissue revitalization. After two years in case 1 the tissue is pigmented and alopecic; in case 2 the epidermis is keratinized, uniform and with the presence of hairs, in a smaller dimension there is pigmented tissue.(AU)

Dehiscencia de herida quirúrgica y exposición material de osteosíntesis. ¿Infección segura? / Surgical wound dehiscence and exposed hardware. Infection foretold?

Resumen: Introducción: la dehiscencia de herida quirúrgica con exposición de material de fijación interna es un grave problema en cirugía ortopédica y un factor importante de infección. Objetivo: descripción del caso inusual de un paciente adulto con dehiscencia de la herida quirúrgica y exposición completa de 20 cm de largo de una placa de cúbito tras seis años de la cirugía, sin signos de infección, consolidación ósea y reepitelización debajo de la placa y adherida al hueso. Caso clínico: hombre de 39 años que sufrió una fractura-luxación de Monteggia, abierta grado II y multifragmentaria. El paciente tenía historia de drogodependencia en tratamiento con metadona. Fue tratado con fijación interna del cúbito mediante una placa de reconstrucción larga. Postoperatoriamente, el paciente dejó de acudir para evaluación. A los seis años de la cirugía presentaba una completa exposición de la placa (20 cm de longitud), sin signos de infección y consolidación con malalineación de la fractura. Tras el retiro de la placa se observó epitelización espontánea adherida al lecho óseo cubital. La cobertura cutánea fue completa a los dos meses. Conclusión: aunque inusual, es posible la consolidación ósea y la ausencia de infección en una fractura abierta con exposición de larga evolución de una placa de antebrazo en el adulto.

Abstract: Introduction: surgical wound dehiscence with exposure of internal fixation material is a serious problem in orthopedic surgery and an important factor for infection. Objective: presentation of an unusual case of an adult patient with surgical wound dehiscence and complete exposure of 20 cm of the ulnar plate after six years of surgery, without infection signs, with bone healing and skin behind the plate. Case presentation: 39-year-old man with an open Gustilo II Monteggia fracture-dislocation multifracture. The patient had a history of drug dependence. He had an open reduction and internal fixation with an ulnar reconstruction plate. The patient did not have any follow-up. After six years of the surgery, there was a complete exposure of the plate (20 cm) without infection and healing of the fracture with misalignment. After removing the plate, we observed spontaneous epithelialization attached to the bone bed. Skin coverage was complete at two months. Conclusion: although unusual, bone consolidation without infection is possible in an open fracture with long-standing exposure to a forearm plate in the adult.

Analysis of risk factors of abdominal wound dehiscence after radical cystectomy

SUMMARY OBJECTIVE: Wound dehiscence is associated with high morbidity and mortality. This study aimed to analyze the risk factors and comorbidities in the patients undergoing radical cystectomy with early postoperative wound dehiscence. METHODS: In all, 539 patients with bladder cancer who underwent radical cystectomy and urinary diversion at a single center between January 2008 and January 2022 were included in the study. The data related to the demographics, medical history, and perioperative clinical features were reviewed. Univariate and multivariate regression analysis was performed to identify risk factors for wound dehiscence. RESULTS: The mean age of the patients was 64.2 years (22-91). The mean body mass index was 26.4 kg/m2 (18.7-35.4). Wound dehiscence was observed in 43 (7.9%) of 539 patients. The patients with wound dehiscence had significantly higher mean BMI (27.8 vs. 26.3, p=0.006), ASA scores (p=0.002), history of chronic obstructive pulmonary disease (30.2 vs. 14.3%, p=0.006), diabetes mellitus (44.2 vs. 17.9%, p=0.003), previous abdominal surgery (18.6 vs. 7.7%, p=0.014), and postoperative ileus (58.1 vs. 16.9%, p=0.006). In the multivariable regression model, diabetes mellitus (odds ratio [OR] 4.9, 95%CI 2.3-10.1; p<0.001), postoperative ileus (OR 8.1, 95%CI 4.1-16.5; p<0.001), and chronic obstructive pulmonary disease (OR 2.6, 95%CI 1.2-5.7; p=0.013) were independent predictors of abdominal wound dehiscence following radical cystectomy. CONCLUSION: Diabetes mellitus, chronic obstructive pulmonary disease, and postoperative ileus were strongly associated with abdominal wound dehiscence following radical cystectomy. Both potential preventive and therapeutic interventions may decrease the risk of wound dehiscence.

Prevalence of complicated surgical wounds and related factors among adults hospitalized in public hospitals / Prevalencia de heridas operatorias complicadas y sus factores asociados en adultos hospitalizados en instituciones públicas de salud / Prevalência de ferida operatória complicada e fatores associados em adultos internados em hospitais públicos

ABSTRACT Objective: To estimate the prevalence of complicated surgical wounds and its related factors in hospitalized adults. Method: In this cross-sectional study, information from 251 patients hospitalized in seven public hospitals in Manaus, Brazil, and at risk of suffering surgical site complications after undergoing surgery was analyzed. Data were collected via interviews, physical examinations, and a medical record review from March to June 2015. Prevalence rate was estimated as the ratio between individuals with complications and patients at risk. To explore associated variables, individuals with and without complications were compared via 5% significant logistic regression and bivariate analyses. This study was approved by a research ethics committee. Results: Overall, 15 patients (6%) showed complicated surgical wounds. General hospitalization (p < 0.003), presence of ecchymosis, (p < 0.001), and men (p = 0.047) increased patients' probability of developing complications in 13.9, 10.1, and 8.2 times, respectively. Conclusion: Assessing the prevalence of complicated surgical wounds and its associated factors in adults contributes to their epidemiological understanding, highlighting prevention targets and making data available for scientific comparisons.

RESUMEN Objetivo: Estimar la prevalencia de herida quirúrgica complicada y sus factores asociados en adultos hospitalizados. Método: Estudio transversal, aprobado por el comité de ética. Se analizaron los datos de 251 pacientes, sometidos a cirugía y con riesgo de complicación del sitio quirúrgico, hospitalizados en siete hospitales públicos de Manaos (Brasil); la recolección de datos se dio por entrevistas, examen físico y revisión de historias clínicas, en el periodo de marzo a junio de 2015. La tasa de prevalencia se calculó como la razón entre los individuos con complicaciones y los pacientes de riesgo. Para explorar las variables asociadas, se compararon individuos con y sin complicaciones mediante análisis bivariado y regresión logística, con un nivel de significancia del 5%. Resultados: Fue identificada herida operatoria complicada en quince pacientes (6%). La presencia de equimosis (p < 0,001), ajustada por sexo masculino (p = 0,047) y la hospitalización en clínica general (p < 0,003) aumentaron en 10,1; 8,2 y 13,9 veces, respectivamente, la probabilidad de desarrollar complicaciones. Conclusión: La identificación de la prevalencia de herida quirúrgica complicada en adultos y sus factores asociados contribuye a su comprensión epidemiológica, destacando focos potenciales de prevención y proporcionando datos para la comparación científica.

Conclusão A identificação da prevalência da ferida operatória complicada em adultos e seus fatores associados contribuem para a sua compreensão epidemiológica, destacando alvos de prevenção e disponibilizando dados para comparação científica.

Comparación entre suturas para cierre profundo y superficial en reemplazo total de rodilla: seguimiento a un año / A comparison of sutures for deep and superficial wound closure in total knee arthroplasty: One-year follow-up

Introducción Aunque diferentes materiales y técnicas se han desarrollado para el cierre superficial y profundo en reemplazo total de rodilla (RTR), no hay evidencia que permita dar recomendaciones respecto a una técnica especifica que disminuya complicaciones postoperatorias de la herida. El propósito de este estudio es comparar el uso de dos técnicas de cierre profundo (Sutura barbada vs. Sutura absorbible trenzada) y superficial (grapas vs. sutura de polipropileno) en RTR. Materiales y métodos Estudio observacional retrospectivo en 240 pacientes. Se excluyeron pacientes con antecedente de cirugía abierta previa de rodilla, RTR previo por lesiones tumorales o artrofibrosis. Seguimiento mínimo de 1 año. Resultados Se usaron grapas en 176 pacientes y Prolene® en 64 pacientes. El cierre profundo se realizó con Stratafix® en 164 pacientes y con Vicryl® en 75 pacientes. Encontramos complicaciones relacionadas con la herida y la funcionalidad al año de seguimiento. La infección superficial para el cierre con prolene presento un HR de 2.6 con un intervalo de confianza (IC) de 95%=1.1-6.2; p=0.029 y en el cierre profundo encontramos un HR a favor del Vicryl® de 0.22, IC 95%=0.96-5.8; p=0.05. Conclusiones Este estudio demostró un incremento significativo de la incidencia de infección superficial después de un RTR cuando el cierre profundo se realiza con suturas barbadas y el cierre superficial se realiza con sutura de polipropileno. Sin embargo, no se presentaron diferencias significativas en otras complicaciones relacionadas con la herida y en la funcionalidad postoperatoria con las diferentes técnicas de cierre superficial y profundo evaluadas.

Introduction Different materials and techniques have been developed for superficial and deep closure in total knee replacement (TKR), but there is no solid evidence that allows to recommend a specific technique that decreases the surgical post-operative complications. The purpose of this study is to compare the use of two deep closure techniques (barbed suture vs. braided absorbable suture) and superficial (staples vs. polypropylene suture) in TKR. Materials and methods An observational retrospective study was carried out in 240 patients. Those individuals were excluded with previous open knee surgery, arthrofibrosis, patients who underwent TKR due to tumor lesions or a follow up for less than one year. Results The skin was closed in 176 patients with staples and in 64 patients with Prolene®. Deep closure was performed with Stratafix® in 164 patients and with Vicryl® in 75 patients. Also, complications related to the wound and functionality were recorded in the first postoperative year. Superficial infection for closure with prolene presented an HR in favor of 2.6 with a confidence interval (CI) of 95%=1.1­6.2; p=0.029 and in deep closure a HR in favor of Vicryl® of 0.22, 95% CI=0.96­5.8; p=0.05 Conclusions This study demonstrated a significant increase in the incidence of superficial infection after TKR when deep closure is performed with barbed sutures and superficial closure with polypropylene suture. However, there were no significant differences in other complications related with the wound neither postoperative functionality with the different superficial and deep closure techniques that were evaluated.

Rotura vaginal y evisceración relacionadas a úlcera de contacto por útero prolapsado: reporte de caso / Vaginal rupture and evisceration related to contact ulcer due to prolapsed uterus: case report

RESUMEN La evisceración vaginal se presenta en 0,36% a 0,96% de las pacientes postoperadas de histerectomía. La causa más frecuente es la dehiscencia de la cúpula vaginal, con mayor riesgo en la histerectomía laparoscópica en relación a la de abordaje abierto. Se describe el caso de una mujer de 63 años con historia de prolapso total de útero, sin antecedente quirúrgico, que ingresó a emergencia por evisceración vaginal. La rotura ocurrió en la pared vaginal posterior, en donde se había formado una úlcera por roce. Se realizó laparotomía para reducir el intestino y reparar el desgarro de la pared vaginal. La corrección del prolapso se practicó ocho meses después con resultados satisfactorios. El tipo de cirugía reparadora depende del tipo y viabilidad de la víscera herniada y se puede realizar por vía vaginal, abdominal o combinada, mediante laparotomía o laparoscopia.

ABSTRACT Vaginal evisceration occurs in 0.36% to 0.96% of postoperative hysterectomy patients. The most frequent cause is vaginal vault dehiscence, with a higher risk in laparoscopic hysterectomy than in open approach. We describe the case of a 63-yearold woman with a history of total prolapse of the uterus, with no surgical history, who was admitted to the emergency room for vaginal evisceration. The rupture occurred in the posterior vaginal wall, where a friction ulcer had formed. Laparotomy was performed to reduce the bowel and repair the tear in the vaginal wall. Correction of the prolapse was done eight months later with satisfactory results. The type of reparative surgery depends on the type and viability of the herniated viscus and can be performed vaginally, abdominal or combined, by laparotomy or laparoscopy.

Dehiscencia de cúpula vaginal y evisceración posquirúrgica: reporte de caso / Vaginal vault dehiscence and postoperative evisceration: case report

RESUMEN La dehiscencia de cúpula vaginal es la separación precoz de la incisión vaginal suturada, que en el 70% de los casos se manifiesta con una evisceración de asas intestinales a través del conducto vaginal. Dentro de sus factores de riesgo, destacan la edad y alteraciones en el lugar postoperatorio de histerectomía. El diagnóstico se realiza mediante un adecuado examen físico, y el tratamiento, netamente quirúrgico, involucra el regresar las vísceras intestinales y corregir la dehiscencia. Describimos el caso de una mujer de 50 años, que presentó dehiscencia de la cúpula vaginal con evisceración de una porción de íleon distal, a quien se le practicó tratamiento quirúrgico y farmacológico.

ABSTRACT Vaginal cuff dehiscence is the premature separation of the sutured vaginal incision, which in 70% of the cases manifests with evisceration of intestinal loops through the vaginal canal. Among its risk factors, age and alterations in the postoperative hysterectomy site stand out. The diagnosis is made by means of an adequate physical examination and the treatment, purely surgical, involves the return of the intestinal viscera and correction of the dehiscence. We describe the case of a 50-year-old woman who presented dehiscence of the vaginal vault with evisceration of a portion of the distal ileum, who underwent surgical and pharmacological treatment.

The use of negative-pressure wound therapy after total knee arthroplasty is effective for reducing complications and the need for reintervention.

BACKGROUND: Wound healing complications are causal factors of prosthesis infection and poor postoperative evolution of patients after total knee arthroplasty (TKA). Negative-pressure wound therapy (NPWT) can be an option to minimize these complications. The aim of this study is to compare the complications of patients undergoing TKA who used a portable NPWT device in the immediate postoperative period with those of a control group. METHODS: A total of 296 patients were evaluated. Patients were divided into two groups: those who used NPWT for seven days in the postoperative period (Group 1 - prospective evaluated) and those who used conventional dressings (Group 2 - historical control group). Epidemiological data, comorbidities, local parameters related to the surgical wound and complications were evaluated. RESULTS: The groups did not differ in regard to sex, age and clinical comorbidities. Overall, 153 (51.7%) patients had at least one risk factor for wound complications. Patients who used NPWT had a lower rate of complications (28.5% vs. 45.7%, p = 0.001) and a lower rate of reintervention in the operating room (2% vs. 8.5%, p = 0.001). Patients in group 1 had a lower incidence of hyperaemia (14.7% vs. 40.2%, p = 0.01), skin necrosis (2.1% vs. 8.5%, p = 0.04) and wound dehiscence (3.1% vs 10.1%, p = 0.03). The use of NPWT was a protective factor for the presence of complications, with an odds ratio of 0.36 (95% CI 0.206-0.629). CONCLUSION: The number of complications related to the wound after TKA is high; however, most of them are minor and have no impact on the treatment and clinical evolution of patients. The use of NPWT decreased the number of surgical wound complications, especially hyperaemia, dehiscence and necrosis, and reduced the need for reintervention.

Ações de enfermagem podem prevenir deiscência em ferida operatória? / Can nursing actions prevent surgical wound dehiscence? / ¿Pueden las acciones de enfermería prevenir la dehiscencia de la herida operatoria?

Objetivo: Identificar na literatura científica intervenções de enfermagem úteis para a prevenção de Deiscências em Feridas Cirúrgicas. Método: Trata-se de uma revisão integrativa da literatura, norteada pela pergunta: Há ações de enfermagem que possam contribuir para prevenção de deiscência em ferida operatória? Realizou-se a busca no período de março de 2019, incluindo artigos publicados a partir do ano de 1990 até 2018. Para a seleção dos artigos foram utilizadas as seguintes bases de dados e/ou portais: National Library of Medicine (PubMed); Web of Science; Scopus Info Site (Scopus); Literatura Latino-Americana e do Caribe em Ciência da Saúde (LILACS) e Cumulative Index to Nursing and Allied Health Literature (CINHAL). Resultados: A busca resultou em 64 artigos, excluíram-se quatro por estarem duplicados e 40 por não atenderem aos critérios de inclusão (24 por serem sobre tratamento, 13 pela natureza do artigo, dois por não estarem disponíveis e um por ser em francês). Vinte artigos foram avaliados na íntegra e 14 foram excluídos por não responderem à questão norteadora desta revisão. Dessa maneira, ao fim desse processo de análise, foram selecionados seis artigos que responderam aos critérios de inclusão e constituíram a amostra final. Conclusão: Houve pouca produção da enfermagem sobre o tema. As principais ações de enfermagem para prevenção de deiscência em feridas cirúrgicas estão associadas à prevenção de infecções de sítio cirúrgico e à indicação e à utilização de terapia de cobertura a vácuo.

Objective: To identify useful nursing interventions for preventing Surgical Wound Dehiscence in scientific literature. Method: This is an integrative literature review, guided by the question: are there nursing actions that can contribute to the prevention of surgical wound dehiscence? The search was carried out in March 2019, including articles published from 1990 to 2018. We used the following databases and/or portals to select the articles: National Library of Medicine (PubMed); Web of Science; Scopus Info Site (Scopus); Latin American and Caribbean Health Sciences Literature (LILACS), and Cumulative Index to Nursing and Allied Health Literature (CINHAL). Results: The search resulted in 64 articles. We excluded four of them for being duplicates, and another 40 that did not meet the inclusion criteria (24 were about treatment, 13 due to the nature of the article, two were not available, and one was in French). Twenty articles were fully evaluated, and 14 were excluded because they did not answer the guiding question of this review. Thus, at the end of this analysis process, we selected six articles that met the inclusion criteria and constituted the final sample. Conclusion: The nursing production on the subject was scarce. The main nursing actions for preventing surgical wound dehiscence are associated with the prevention of surgical site infections and the indication and use of negative pressure wound therapy.

What Is the Impact of Residual Obesity on the Risk for Postoperative Body-Contouring Surgery Complications in Postbariatric Patients?

BACKGROUND: There are an increasing number of patients presenting for plastic surgery after massive weight loss, and many of these patients have residual obesity that may compromise outcomes. The impact of residual obesity on the development of postoperative complications in postbariatric patients undergoing plastic surgery procedures is unclear. METHODS: We report the outcomes of 207 patients who underwent plastic surgery following RYGB from January 2011 to December 2018. RESULTS: Two hundred and seven patients (196 females, 11 males) with a mean age of 42 years underwent 335 separate operations. The average BMI at the time of plastic surgery was 27.43 kg/m2. The average weight loss was 47.08 kg. The prevalence of comorbidities was 26.6% and the most important presurgery comorbidities were arterial hypertension (10.1%) and diabetes mellitus (4.8%). Of the 207 patients who underwent surgery, 78.3% (168/207) underwent abdominoplasty and 45.0% underwent mammoplasty. The overall rate of complications was 27.5%. The prevalence of postoperative complications was not significantly different between patients with a BMI ≥ 30 kg/m2 and patients with a BMI < 30 kg/m2 (33.3% vs 25.9%, respectively; p = 0.344). CONCLUSION: In this group of patients, with specified anthropometric and clinical profiles, the residual obesity did not influence the incidence of postoperative complications in postbariatric patients after plastic surgery.
