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.

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.

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.

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.

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.

Management of transvaginal bowel evisceration secondary to vaginal cuff dehiscence following hysterectomy: Case report and review of the literature / Manejo de evisceración intestinal transvaginal secundaria a dehiscencia de la cúpula vaginal posterior a histerectomía: reporte de caso y revisión de la literatura

ABSTRACT Objetives: To report a case of transvaginal bowel evisceration following total abdominal hysterectomy, and to conduct a review of the literature on its diagnosis and treatment. Materials and methods: A 48-year-old female patient who presented to a high complexity institution with transvaginal bowel evisceration lasting 10 hours. Laparotomy was performed in order to reduce the evisceration and repair the vaginal vault defect. A search was conducted in Medline via PubMed, Embase, Elsevier, Medigraphic, Wolters Kluwer Health and UpToDate using the terms "vaginal vault dehiscence," "transvaginal bowel evisceration," "dehiscence following hysterectomy," "hysterectomy complications," and using a snowball search strategy based on the studies identified, both in English and Spanish. Results: Fourteen studies were included. The diagnosis of transvaginal evisceration is primarily clinical with the observed bulging of the abdominal content through the vagina. It may also be associated with signs of peritonitis or bowel obstruction. Initial management must be an attempt at vaginal packing and prophylactic antibiotics. Several surgical techniques have been described for vaginal vault correction and reinforcement of dehiscence closure. Conclusions: Transvaginal evisceration is considered a surgical emergency. Further studies assessing the safety and effectiveness of the various management interventions are required.

RESUMEN Objetivos: reportar un caso de evisceración intestinal transvaginal posterior a histerectomía abdominal total y realizar una revisión de la literatura sobre su diagnóstico y tratamiento.

Se hace una búsqueda en Medline vía PubMed, Embase, Elsevier, Medigraphic, Wolters Kluwer Health y UpToDate con los términos: "dehiscencia de cúpula vaginal", "evisceración intestinal transvaginal", "dehiscencia posterior a histerectomía", "complicaciones histerectomía", y en bola de nieve a partir de los estudios identificados, en idiomas inglés y español. Resultados: se incluyeron 14 estudios. El diagnóstico de la evisceración transvaginal es eminentemente clínico al observar salida de contenido abdominal por vagina, se puede asociar a signos de peritonitis u obstrucción intestinal. Su manejo inicial debe intentar el empaquetamiento vaginal y la profilaxis antibiótica Se han descrito varias técnicas quirúrgicas para corregir el defecto de la cúpula vaginal y reforzar el cierre de la dehiscencia de la cúpula. Conclusiones: la evisceración transvaginal se considera una urgencia quirúrgica. Se requieren más estudios que evalúen la seguridad y la efectividad de las diferentes intervenciones para el manejo.

Incisional negative-pressure wound therapy in revision total hip arthroplasty due to infection / Terapia de pressão negativa incisional na revisão de artroplastia total do quadril por infecção

ABSTRACT Objective: To present our institution's experience with negative-pressure wound therapy (NPWT) as an adjuvant in wound healing of patients who have undergone revision total hip arthroplasty (THA) due to septic loosening in the presence of active fistula. Methods: We prospectively assessed patients presenting with THA infection, associated with the presence of fistula, treated with a PICO® device for NPWT, in combination with the standard treatment for prosthesis infection in our institution. Resolution of the infectious process and healing of the surgical wound without complications were considered an initial favorable outcome. Results: We assessed 10 patients who used PICO® in our department. No complications were identified in association with the use of the NPWT device. The mean follow-up of the patients after use of the device was 12.7 months. Only one patient progressed with fistula reactivation and recurrence of infection. Conclusion: NPWT can be used in wound complications and infection following THA procedures safely and with promising results. Randomized prospective studies should be conducted to confirm its effectiveness. Level of Evidence IV, Case Series.

RESUMO Objetivo: Apresentar a experiência com terapia com pressão negativa (TPN), como adjuvante no tratamento das feridas cirúrgicas de pacientes submetidos à revisão decorrente de solturas sépticas com presença de fístula ativa em artroplastias totais do quadril (ATQ). Métodos: Foram avaliados prospectivamente pacientes que apresentavam infecção de ATQ, associada à presença de fístula, tratados com dispositivo PICO® para TPN, além do tratamento padrão da infecção protética em nossa instituição. Consideramos como desfecho favorável inicial a resolução do processo de infecção e a cicatrização da ferida operatória, sem eventos complicadores. Resultados: Foram acompanhados 10 pacientes que usaram PICO® em nosso serviço. Mão foram identificadas quaisquer complicações com relação ao uso do dispositivo de TPN. A média de acompanhamento dos pacientes após o uso do dispositivo foi de 12,7 meses. Apenas um paciente evoluiu com recidiva da infecção e reativação da fístula. Conclusão: A TPN pode ser usada em complicações de feridas e infecção depois de ATQ com segurança e com resultados promissores. Estudos prospectivos randomizados devem ser realizados para comprovar sua eficácia. Nível de Evidência IV, Série de Casos.

Effect of retension sutures on abdominal pressure after abdominal surgery / 中华创伤杂志(英文版)

<p><b>PURPOSE</b>To evaluate the effect of retention sutures on abdominal pressure and postoperative prognosis in abdominal surgery patients.</p><p><b>METHODS</b>This prospective cohort study included patients who were admitted to Daping Hospital from May 15, 2014 to October 11, 2014. A total of 57 patients were enrolled, including 18 patients in the "U" type retention suture group, 17 patients in the intermittent retention suture group, and 22 patients in non-retention suture group. The demographic data, clinical data and risk factors for abdominal wound dehiscence were recorded. The bladder pressure (IVP) was monitored preoperatively, intraoperatively, and four days postoperatively. Additionally, the incidence of abdominal wound dehiscence and infection 14 days after the operation was recorded.</p><p><b>RESULTS</b>During the operation, the IVP decreased and then increased; it was at its lowest 1 h after the start of the operation (5.3 mmHg ± 3.2 mmHg) and peaked after tension-reducing (8.8 mmHg ± 4.0 mmHg). The IVP values in the "U" type retention suture group and intermittent retention suture group were higher than in the non-retention suture group 4 days after operation (p < 0.005). The Visual Analogue Scale (VAS) pain scores were 3.9 ± 2.2, 3.8 ± 2.0, and 3.0 ± 1.0 in the retention suture group, intermittent retention suture group and non-retention suture group, respectively. The VAS pain scores in the "U" type tension-reducing group and intermittent tension-reducing group were higher than in the non-tension-reducing group (p < 0.005).</p><p><b>CONCLUSION</b>Although retention sutures may reduce the incidence of postoperative wound dehiscence in abdominal surgery patients, they can increase the IVP and postoperative pain.</p>

Factors associated with complex surgical wounds in breast and abdomen: a case-control observational study / Fatores associados à ferida cirúrgica complexa em regiões de mama e abdome: estudo observacional caso-controle / Factores asociados a la herida quirúrgica compleja en regiones de mama y abdomen: estudio observacional caso-control

ABSTRACT Objective: to identify factors associated with complex surgical wounds in the breasts and abdomen in outpatients. Method: observational case-control study involving 327 patients, distributed into 160 cases (complex surgical wound) and 167 controls (simple surgical wound). Data were extracted from the medical records and a binary logistic regression model was used for analysis, considering a significance level of 5%. Results: the factors associated with greater chance of occurrence of complex surgical wound were 18 to 59 years of age (p = 0.003), schooling < 8 years (p = 0.049), radiotherapy (p < 0.001), hysterectomy (p = 0.003), glycemia (≤ 99 mg/dL) and arterial hypertension (p = 0.033), while quadrantectomy (p = 0.025) served as a protective factor. Conclusion: radiotherapy was the most significant factor for surgical wound complications. Glycemic alteration was an unexpected result and shows the need for further studies related to this topic.

Application of unilateral pectoralis major muscle flap in the treatment of sternal wound dehiscence

Abstract Objective: This study aims to report the use of the unilateral pectoralis major muscle flap for the treatment of the sternal wound dehiscence. Methods: A retrospective study including patients who underwent unilateral pectoralis major muscle flap was performed for the treatment of sternotomy dehiscence due to coronary artery bypass, valve replacement, congenital heart disease correction and mediastinitis, between 1997 and 2016. Data from the epidemiological profile of patients, length of hospital stay, postoperative complications and mortality rate were obtained. Results: During this period, 11 patients had their dehiscence of sternotomy treated by unilateral pectoralis major muscle flap. The patients had a mean age of 54.7 years, the mean hospital stay after flap reconstruction was 17.9 days (from 7 to 52 days). In two patients, it was necessary to harvest a flap from the rectus abdominis fascia, in association with the pectoralis major muscle flap, to facilitate the closure of the distal wound. In the postoperative period, seroma discharge from the surgical wound was observed in six patients, five reported intense pain (temporary), three had partial cutaneous dehiscence, and two presented granuloma of the incision. Conclusion: The complex wound from sternotomy dehiscences presents itself as a challenge to surgical teams. Treatment should include debridement of necrotic tissue and preferably coverage with well-vascularized tissue. We propose that the unilateral pectoralis major muscle flap is an interesting and low morbidity option for the reconstruction of sternal wound dehiscences, with proper sternum stability and satisfactory functional and aesthetic outcomes.

NEGATIVE-PRESSURE WOUND THERAPY IN THE TREATMENT OF COMPLEX INJURIES AFTER TOTAL KNEE ARTHROPLASTY / TERAPIA COM PRESSÃO NEGATIVA EM FERIDAS NO TRATAMENTO DE LESÕES GRAVES APÓS ARTROPLASTIA TOTAL DO JOELHO

ABSTRACT Objective: To present an experience with negative-pressure wound therapy (NPWT) in the treatment of surgical wounds in patients treated for infections after total knee arthroplasty (TKA) with or without dehiscence and prophylaxis in wounds considered at risk of healing problems. Methods: We prospectively evaluated patients with TKA infection with or without surgical wound dehiscence and patients with risk factors for infection or surgical wound complications treated with Pico(r) device for NPWT in addition to standard treatment of infection or dehiscence in our institution. We considered as an initial favorable outcome the resolution of the infectious process and the closure of the surgical wound dehiscences in the treated cases and the good progression of the wound without complicating events in the prophylactic cases. Results: We evaluated 10 patients who used Pico(r) in our service. All patients had a favorable outcome according to established criteria. No complications were identified regarding the use of the NPWT device. The mean follow-up of the patients after the use of the device was 10.5 months. Conclusion: The NPWT can be safely used in wound infections and complications following TKA with promising results. Long-term randomized prospective studies should be conducted to prove its effectiveness. Level of Evidence IV, Case Series.

RESUMO Objetivo: Apresentar uma experiência com a terapia com pressão negativa (TPN) no tratamento das feridas cirúrgicas de pacientes tratados por infecções em artroplastias totais do joelho (ATJ) associadas ou não à deiscência e como profilaxia nas feridas consideradas em risco de problemas de cicatrização. Métodos: Foram avaliados prospectivamente pacientes que apresentavam infecção de ATJ associada ou não à deiscência de ferida operatória e pacientes com fatores de riscos de infecção ou complicações de ferida cirúrgica tratados com dispositivo PICO(r) para TPN além do tratamento padrão da infecção ou deiscência em nossa instituição. Consideramos como desfecho favorável inicial a resolução do processo de infecção e o fechamento das deiscências de ferida operatória nos casos de tratamento e a boa evolução da ferida operatória, sem eventos complicadores, nos casos profiláticos. Resultados: Foram avaliados 10 pacientes que usaram PICO(r) em nosso serviço. Todos os pacientes apresentaram desfecho favorável de acordo com os critérios estabelecidos. Não foram identificadas quaisquer complicações com relação ao uso do dispositivo de TPN. A média de seguimento dos pacientes após o uso do dispositivo foi de 10 meses e meio. Conclusão: A TPN pode ser usada em complicações de ferida e infecção depois de ATJ de maneira segura e com resultados promissores. Estudos prospectivos randomizados prolongados devem ser realizados para comprovar sua eficácia. Nível de Evidência IV, Série de Casos.

Negative pressure therapy for the treatment of complex wounds / Terapia por pressão negativa no tratamento de feridas complexas

ABSTRACT The objective of this study is to evaluate the effectiveness of negative pressure therapy (NPT) in the treatment of complex wounds, with emphasis on its mechanisms of action and main therapeutic indications. We searched the Pubmed / Medline database for articles published from 1997 to 2016, and selected the most relevant ones. The mechanisms of action of NPT involveboth physical effects, such as increased perfusion, control of edema and exudate, reduction of wound dimensions and bacterial clearance, and biological ones, such as the stimulation of granulation tissue formation, microdeformations and reduction of Inflammatory response. The main indications of NPT are complex wounds, such as pressure ulcers, traumatic wounds, operative wound dehiscences, burns, necrotizing wounds, venous ulcers, diabetic wounds, skin grafts, open abdomen, prevention of complications in closed incisions and in the association with instillation of solutions in infected wounds.

RESUMO O objetivo desse estudo é avaliar a eficácia da terapia por pressão negativa (TPN) no tratamento de feridas complexas, com ênfase em seus mecanismos de ação e principais indicações terapêuticas. Foi realizada revisão na base de dados Pubmed / Medline, em artigos publicados de 1997 a 2016, e selecionados os mais relevantes. O mecanismo de ação da TPN envolve efeitos físicos, como o aumento da perfusão, controle do edema e do exsudato, redução das dimensões da ferida e depuração bacteriana, e biológicos, como o estímulo à formação de tecido de granulação, microdeformações e redução da resposta inflamatória local. As principais indicações da TPN são as feridas complexas como úlceras por pressão, feridas traumáticas, deiscências de ferida operatória, queimaduras, feridas necrotizantes, úlceras venosas, feridas diabéticas, os enxertos de pele, o abdome aberto, na prevenção de complicações em incisões fechadas e na associação com instilação de soluções em feridas infectadas.

El 29,7 % de los pacientes presentaron complicaciones posoperatorias y se presentó una mortalidad de 9,7 %. La mediana de la estancia hospitalaria fue de 8 días (RIC: 5 a 16). Conclusiones. La incidencia de fístula de la anastomosis que se presentó estuvo acorde con lo reportado en la literatura científica a nivel mundial. El antecedente de cirugía abdominal así como la cirugía de urgencia fueron los factores frecuentes entre los pacientes que presentaron falla anastomótica

Introduction: Anastomotic leak is one of the main complications of patients submitted to gastrointestinal surgery. It occurs in approximately in 3.4% to 15% of cases. In Colombia the overall incidence of anastomotic leak is not known. Material and methods: A prospective cohort study that included patients undergoing anastamosis and who were followed up for up to 30 days. A descriptive analysis of the information was performed. The variables were analyzed with the chi-square test and the Kaplan-Meller graphs were used to determine the time to the event. Data analyses was performed on STATA 13. Results: 195 patients were admitted. 47.1% were male, and the median age of the study group was 60 years (ICR: 48-70). The incidence of anastomotic failure was 10.8% and the incidence rate was 10.2 per 1000 person-years; 29.7% of the patients presented postoperative complications and a mortality rate of 9.7%. The median hospital stay was 8 days (ICR: 5 - 16). Conclusion: The incidence of anastomotic leak observed appears in accordance with reports published in the world literature. The history of abdominal surgery as well as emergency surgery were the most frequent factors among the patients who developed anastomosis leak

Analysis of biomechanical parameters in colonic anastomosis / Análise de parâmetros biomecânicos em anastomoses colônicas

ABSTRACT Background: The use of measures in colonic anastomoses to prevent dehiscences is of great medical interest. Sugarcane molasses, which has adequate tolerability and compatibility in vivo, has not yet been tested for this purpose. Aim: To analyze the biomechanical parameters of colonic suture in rats undergoing colectomy, using sugarcane molasses polysaccharide as tape or gel. Methods: 45 Wistar rats (Rattus norvegicus albinus) were randomized into three groups of 15 animals: irrigation of enteric sutures with 0.9% saline solution; application of sugarcane molasses polysaccharide as tape; and sugarcane molasses polysaccharide as gel. The rats underwent colon ressection, with subsequent reanastomosis using polypropylene suture; they were treated according to their respective groups. Five rats from each group were evaluated at different times after the procedure: 30, 90 and 180 days postoperatively. The following variables were evaluated: maximum rupture force, modulus of elasticity and specific deformation of maximum force. Results: The biomechanical variables among the scheduled times and treatment groups were statistically calculated. The characteristics of maximum rupture force and modulus of elasticity of the specimens remained identical, regardless of treatment with saline, polysaccharide gel or tape, and treatment time. However, it was found that the specific deformation of maximum force of the intestinal wall was higher after 180 days in the group treated with sugarcane polysaccharide gel (p=0.09). Conclusion: Compared to control, it was detected greater elasticity of the intestinal wall in mice treated with sugarcane polysaccharide gel, without changing other biomechanical characteristics, regardless of type or time of treatment.

RESUMO Racional: A aplicação de produtos em anastomoses colônicas que possam prevenir o surgimento de deiscências são de grande interesse médico. O emprego do polissacarídeo de melaço de cana-de-açúcar (Saccharum officinarum), que possui adequada tolerabilidade e compatibilidade in vivo, ainda não foi testado para este fim. Objetivo: Analisar os parâmetros biomecânicos em suturas colônicas de ratos submetidos à colectomia esquerda após aplicação de fita ou gel do polissacarídeo do melaço da cana-de-açúcar no sítio cirúrgico. Métodos: Quarenta e cinco ratos (Rattus norvegicus albinus da linhagem Wistar) foram sorteados em três grupos de 15 submetidos a: irrigação das suturas entéricas com soro fisiológico a 0,9%; aplicação de fita de polissacarídeo do melaço da cana-de-açúcar; e aplicação do gel do mesmo melaço. Os ratos foram submetidos à colectomia esquerda com anastomose primária, e tratados segundo os respectivos grupos. Cinco ratos de cada grupo foram avaliados em diferentes tempos após o procedimento: 30º, 90º e 180º dias de pós-operatório. Foram avaliadas as variáveis de força máxima de ruptura, módulo de elasticidade e deformação específica da força máxima. Resultados: As variáveis biomecânicas entre os tempos de coleta da pesquisa e os grupos de tratamento foram analisados estatisticamente. As características biomecânicas de força máxima de ruptura e o módulo de elasticidade do corpo de prova permaneceram idênticas, independente do tratamento com soro, fita ou gel de polissacarídeo, e do tempo de tratamento. No entanto, foi evidenciada maior deformação específica da força máxima da parede intestinal, aos 180 dias nos ratos tratados com gel de polissacarídeo de cana-de-açúcar. (p=0,09). Conclusão: Em relação ao controle, foi detectada maior elasticidade da parede intestinal nos ratos tratados com gel de polissacarídeo de cana-de-açúcar, sem alteração de outras características biomecânicas, independente do tipo ou tempo de tratamento.

Traumatic wound dehiscence after corneal keratoplasty / Deiscência de sutura pós-trauma ocular em olhos submetidos a transplante de córnea

ABSTRACTPurpose:To assess patient characteristics, risk factors, outcomes, and the treatment of wound dehiscence (WD) in patients after corneal keratoplasty.Methods:Retrospective chart review of 11 eyes of 11 patients with corneal grafts who underwent repair of WD from January 1, 2004 to December 31, 2012 at Hospital Oftalmologico de Brasilia.Results:Eight (72.7%) patients were men and three were women. Six (54.5%) patients had deep anterior lamellar keratoplasty (DALK) and 5 had penetrating keratoplasty. The mean age at trauma was 31.1 years. The mean time from corneal keratoplasty to WD was 12.82 months (range, 3-33 months). The mean best-corrected visual acuity of patients before trauma was 20/60 (0.48 logMAR) and after final treatment was 20/160 (0.90 logMAR) (P=0.15). In one case, visual acuity decreased to no light perception because of retinal detachment and phthisis bulbi. Accidental blunt trauma and fall were the most common causes of WD.Conclusion:Patients who undergo corneal keratoplasty have a life-long risk of WD. The full-thickness rupture at the graft-host junction in our study suggests that the junction remains vulnerable, even following DALK, and can rupture with trauma. In our series, depending upon the severity of the trauma, postkeratoplastic WD can be associated with a good visual prognosis.

RESUMOObjetivo:Avaliar as características, os fatores de risco, resultados, e tratamento de pacientes que apresentaram deiscência traumática de sutura após transplante de córnea.Métodos:Estudo retrospectivo em que foram avaliados 11 olhos de 11 pacientes submetidos a transplante de córnea e que desenvolveram deiscência de sutura entre janeiro de 2004 e dezembro de 2012 no Hospital Oftalmológico de Brasília.Resultados:Oito (72,7%) pacientes eram homens e três mulheres. Seis (54,5%) pacientes foram submetidos a ceratoplastia lamelar anterior profunda (DALK) e 5 pacientes a ceratoplastia penetrante (PK). A média de idade dos pacientes no momento do trauma era de 31,1 anos. O tempo médio entre o transplante de córnea e a deiscência de sutura foi de 12,82 meses (variando de 3 a 33 meses). A melhor acuidade visual corrigida (AVCC) doa pacientes antes do trauma era de 20/60 (0,48 logMAR), e após o trauma era de 20/160 (0,90 logMAR) (P=0,15). Em um caso, a acuidade visual reduziu para sem percepção luminosa devido a descolamento de retina e posterior atrofia bulbar. O trauma ocular acidental e a queda da própria altura foram as principais causas de deiscência de sutura nos olhos transplantados.Conclusão:Pacientes previamente submetidos a transplante de córnea apresentam um risco prolongado de deiscência de sutura. A ruptura completa na junção doador-receptor no nosso estudo sugere que mesmo após um DALK a junção permanece vulnerável e pode romper com o trauma. Na nossa série, dependendo da severidade do trauma, a deiscência pós-ceratoplastia pode estar associada a um bom prognóstico visual.
