ABSTRACT

SUMMARY: The studies of the properties of vascular structures and tissues during electric welding, in particular direct morphological changes in the blood vessel walls in the areas of welding processes, are of interest. Perforating veins, femoral veins, abdominal aorta, vena cava and porcine perforating veins of the limbs were used in this study. We performed end-to-end electric welding of the aorta, venous end-to-side electric welding, vein end-to-artery side arterial and venous welding, venous end-to-end electric welding, as well as arterial and venous lumen sealing.The results of histological studies showed the formation of a coagulated acellular protein matrix, represented by unorganized denatured protein fibrous structures. In the area of vascular tissue coagulation, lacunes were formed as a result of water evaporation from the biological tissue. In the perifocal area of the welded junction, cell reduction occurred without necrosis or charring. The data obtained confirm the safety of high frequency electric welding of the main vessels and the prospectfor clinical use of the studied techniques.


RESUMEN: Los estudios de las propiedades de las estructuras y tejidos vasculares durante la soldadura eléctrica son relevantes, en particular los cambios morfológicos directos en las paredes de los vasos sanguíneos en las áreas de los procesos de soldadura. En este estudio se utilizaron venas perforantes, venas femorales, parte abdominal de la aorta, vena cava y venas perforantes porcinas de los miembros. Realizamos soldadura eléctrica de extremo a extremo de la parte abdominal de la aorta, soldadura eléctrica de extremo a lado venosa, soldadura arterial y venosa de extremo a arteria del lado venoso, soldadura eléctrica de extremo a extremo venoso, así como lumen arterial y venoso. Los resultados de los estudios histológicos mostraron la formación de una matriz de proteína acelular coagulada, representada por estructuras fibrosas de proteínas desnaturalizadas no organizadas. Se formaron lagunas como resultado de la evaporación del agua del tejido biológico en el área de la coagulación del tejido vascular, En el área perifocal de la unión soldada, la reducción celular ocurrió sin necrosis ni carbonización. Los datos obtenidos confirman la seguridad de la soldadura eléctrica de alta frecuencia de los vasos principales y la perspectiva de uso clínico de estas técnicas.

ABSTRACT

Abstract Introduction: The objective of this study is to compare the effects of conventional monopolar electrosurgery (CMES) and low-thermal plasma kinetic cautery (PKC) on complications such as bleeding, abnormal wound healing, pain, and drainage in patients who underwent on-pump coronary artery bypass grafting (CABG). Methods: This retrospective clinical study included 258 patients undergoing CABG; the patients were randomized to PKC (PEAK PlasmaBlade, n=153) and CMES (n=105) groups. The patients' clinical data were examined retrospectively for biochemical variables, postoperative drainage, post-surgery erythrocyte suspension transfusion count, surgical site pain examined with visual analogue scale (VAS), and wound healing. Two-sided P-value > 0.05 was considered as statistically significant. Results: The median post-surgery erythrocyte suspension transfusion number was significantly lower with PKC compared to CMES (0 [0-1] vs. 1 [1-4], respectively, P<0.001). Mean postoperative drain output and time until removal of drain tubes were significantly lower with PKC compared to CMES (300±113 vs. 547±192 and 1.95±1.5 vs. 2.44±1.8; P<0.001 and P=0.025, respectively). Mean VAS score for spontaneous and cough-induced pain were significantly lower with PKC compared to CMES (1.98±1.51 vs. 3.94± 2.09 and 3.76±1.46 vs. 5.6±1.92; P<0.001 for both comparisons). Reoperation due to bleeding was significantly higher with CMES compared to PKC (0 vs. 11 [7.2%], P=0.001). Conclusion: Use of PKC during CABG considerably reduces postoperative drainage, need for blood transfusion, reoperation due to bleeding, and postoperative pain. PCK appears to be a good alternative to CMES for CABG.

ABSTRACT

La percepción hacia el alcance de la excelencia estética se traduce especialmente en saber interpretar y satisfacer los deseos del paciente, empleándose para eso, todos los conocimientos disponibles en la literatura científica. La utilización de carillas, coronas cerámicas o de Circonio pueden representar un tratamiento, predecible y confiable, cuando las condiciones, básicas de salud se encuentran ya resueltas. Una de estas condiciones, se refiere a un marco de salud Periodontal, con contornos gingivales estéticos y naturales. En algunos casos, donde esto no sucede, la microcirugía estética puede ser un recurso práctico y predecible. A su vez la evidencia científica nos ofrece parámetros para guiarnos y así alcanzar un correcto diagnóstico, planeamiento seguro, técnica adecuada y la utilización del material más indicado para cada situación clínica. La subjetividad estética puede estar escondida entre líneas en la ciencia. Con ésta recopilación acompañado con la ejemplificación de los casos clínicos desarrollados, intentaremos aproximarnos a la excelencia (AU)

ABSTRACT

Se entiende por agrandamiento gingival el incremento en masa y volumen del tejido gingival. Se considera una condición benigna de la cavidad oral, por lo general de manejo rutinario, que logra regularse con medidas simples de control del biofilm microbiano. El agrandamiento gingival puede ser producido por diversas condiciones clínicas, hereditarias, deficiente higiene oral o fármacos. La epilepsia afecta a 1% de la población mundial y requiere el uso de fármacos antiepilépticos o anticonvulsivantes para lograr su control, dentro de éstos la fenitoína actúa como un bloqueador selectivo de los canales de sodio sensibles al voltaje y constituye uno de los fármacos más empleados por su capacidad en el control de crisis focales y generalizadas. La fenitoína se ha relacionado con los agrandamientos gingivales como uno de sus efectos adversos, los cuales se incluyen dentro de las enfermedades por fármaco inducidas en la cavidad oral. El objetivo de este artículo es brindar la información necesaria sobre el manejo correcto de pacientes con agrandamiento gingival producido por fenitoínas y a la vez poder conocer las consecuencias de estos fármacos en la cavidad oral (AU)


Gingival enlargement means the increase in mass and volumen of the gingival tissue. It is considered a benign condition of the oral cavity, usually of routine management, wich can be regulated with simple measures of biofilm control. The gingival enlargement can be produced by diverse clinical conditions, hereditary deficient oral higiene or drugs. Epilepsy affects 1% of the world population and requires the use of antiepileptic or anticonvulsant drugs to achieve its control, within these phenytoin acts as selective blocker or voltage ­ sensitive sodium channels and is one of the most used grugs for its ability to control focal and generalized crises. Phenytoin has been linked to gingival enlargement as one of its adverse effects which is included within the drug diseases induced in the oral cavity. The objective of this article is to provide the necessary information on the correct managment of patients with gingival enlargemen produced by phenytoins and at the same time to know the consequences of these drugs in the oral cavity (AU)

ABSTRACT

El póntico E es una alternativa de tratamiento para la pérdida prematura dental, este tipo de póntico fue publicado por primera vez en 2014 por Robert P. Korman. El diseño del póntico permite ofrecer predictibilidad en cuanto a soporte y mantenimiento de la arquitectura gingival, también promueve que el tejido vestibular migre coronalmente sobre el póntico, creando un surco gingival. Se recibió a una paciente que presentaba fragmento radicular del diente 21 y ausencia del diente 12, reborde residual atrófico (clase I según Seibert). Como plan de tratamiento, se realizó la extracción atraumática del fragmento radicular del diente 21 para retardar el colapso del reborde alveolar y se colocó injerto de tejido conectivo en la zona del diente 12 para corregir el defecto clase I de Seibert, se realizó la conformación de los nichos gingivales con electrobisturí en conjunto con la prótesis provisional y la preparación de los dientes pilares para la recepción y rehabilitación con pónticos E. Se colocó una prótesis fija de cinco unidades (dientes 13 al 23) en material núcleo de Zr y estratificada con cerámica (AU)


Pontic E is an alternative treatment for premature dental loss, this type of pontic was published for the first time in 2014 by Robert P. Korman. The design of the pontic allows to offer predictability in terms of support and maintenance of the gingival architecture, it also promotes that the vestibular tissue migrates coronally over the pontic, creating a gingival groove. A patient was received who presented a radicular fragment of tooth 21 and absence of tooth 12, atrophic residual ridge (class I according to Seibert). As a treatment plan, atraumatic extraction of the root fragment of tooth 21 was performed to delay the collapse of the alveolar ridge and connective tissue graft was placed in the area of tooth 12 to correct Seibert's class I defect, conformation was performed of the gingival niches with electrocautery in conjunction with the provisional prosthesis and the preparation of the abutment teeth for the reception and rehabilitation with pontics E. A fixed prosthesis of five units was placed (teeth from 13 to 23) of Zr core material and stratified with ceramic (AU)

ABSTRACT

SUMMARY OBJECTIVE To evaluate the effectiveness of electrosurgery fulguration as a treatment for Bartholin's gland cysts. DESIGN Retrospective study with a comparative control group performed on Hospital Brigadeiro and in the Disciplina de Ginecologia do Departamento de Obstetrícia e Ginecologia, Hospital das Clínicas, Faculdade de Medicina da Universidade de São Paulo from February 2005 to March 2009. Patients: Patients with Bartholin's gland cyst were divided into three treatment groups: group 1 electrosurgery (n=169 cases); group 2 - gland excision with the conventional technique using a cold scalpel (n = 51 cases); group 3 - marsupialization (n=11 cases). We reviewed the clinical and surgical history, physical examination, description of the surgical technique, postoperative results (success and complications), and follow-up data. RESULTS There is no difference between groups in relation to intraoperative bleeding, hematoma, and complete healing in a single treatment session. However, electrosurgery shows the lower percentage of recurrences 18 (10,7%) compared to the Marsupialization technique (group 3, p=.031). Recurrences occurred in 18 (10,7%), 3 (5,9%), and 4 (36,4%) cases. After retreatment by the same technique, there was a complete cure rate of 90% (152/169) for group 1, and 98% (50/51) for group 2. The cost of group 1 was lower than that of other groups. CONCLUSION The fulguration with electrosurgery of the capsule of Bartholin's cyst is an effective method of treatment, andthe cost of this technique is lower than the conventional technique and marsupialization.


RESUMO OBJETIVO Avaliar a eficácia da fulguração da eletrocirurgia como tratamento para os cistos da glândula de Bartholin. MÉTODOS Estudo retrospectivo, grupo controle comparativo realizado no Hospital Brigadeiro e disciplina de Ginecologia do Departamento de Obstetrícia e Ginecologia do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, de fevereiro de 2005 a março de 2009. Pacientes com cisto de glândula de Bartholin foram divididos em três grupos de tratamento: grupo 1 - eletrocirurgia (n = 169 casos); grupo 2 - excisão da glândula com técnica convencional utilizando bisturi frio (n = 51 casos); grupo 3 - marsupialização (n = 11 casos). Revisamos a história clínica e cirúrgica, o exame físico, a descrição da técnica cirúrgica, os resultados pós-operatórios (sucesso e complicações) e os dados de acompanhamento. RESULTADOS Não há diferença entre os grupos em relação ao sangramento intraoperatório, hematoma e cicatrização completa em uma única sessão de tratamento. No entanto, a eletrocirurgia mostrou o percentual mínimo de recidivas, 18 (10,7%), em relação à técnica de marsupialização (grupo 3, p = 0,031). Recorrências ocorreram em 18 (10,7%), três (5,9%) e quatro (36,4%) casos. Após o retratamento pela mesma técnica, houve taxa de cura completa: 90% (152/169) para o grupo 1 e 98% (50/51) para o grupo 2. O custo do grupo 1 foi menor do que os dos outros grupos. CONCLUSÃO A fulguração com eletrocirurgia da cápsula do cisto de Bartholin é um método efetivo de tratamento, mas o custo dessa técnica é menor do que a técnica de convenção e a marsupialização.

ABSTRACT

Resumo Fogo em campo cirúrgico durante cirurgia palpebral é uma complicação intra-operatória que é dramática tanto para o paciente quanto para a equipe médica. Relatamos um caso de acidente cirúrgico durante cirurgia palpebral onde o paciente sofreu queimadura de supercílio. Houve interação entre o oxigênio usado para sedação (máscara aberta) e uma fonte de ignição representada pelo cautério monopolar. Embora o paciente tenha apresentado boa evolução clínica com recuperação total da lesão cutânea, este caso é um alerta para se evitar tais tipo de ocorrência. Ressaltamos neste trabalho quais as condições implicadas e o modo de prevenção.

ABSTRACT

La aplicación del LÁSER (light amplification of stimulation emision of radiation) en las áreas de la medicina y la odontología viene demostrando una constante evolución, brindándonos alternativas a los tratamientos convencionales. Los láseres quirúrgicos de tejidos blandos muestran grandes ventajas comparados a los procedimientos habituales de corte, ya sea con bisturí frío o electrobisturí. La mínima necesidad de anestesia, la analgesia intra y postoperatoria, la coagulación inmediata, la cicatrización por segunda, el efecto bactericida, la ausencia de puntos de sutura, el confort postoperatorio, son algunas de las ventajas que hacen que la cirugía con láser sea una opción indiscutible que está ganando terreno entre los profesionales de la salud (AU)

ABSTRACT

Debido al acelerado envejecimiento de la población, cada vez es mayor la cantidad de usuarios portado-res de dispositivos electrónicos cardíacos implan-tables (DECI). Muchos de estos pacientes se verán enfrentados a procedimientos dermatológicos que con frecuencia utilizan equipos de electrocirugía. Es-tos tienen riesgo potencial de producir interferencias electromagnéticas (IEM), y por lo tanto alterar el fun-cionamiento de estos dispositivos. Si bien no todos los DECI tienen las mismas características, las nuevas tec-nologías de estos dispositivos han disminuido, aunque no eliminado completamente, el riesgo de IEM. Este artículo tiene como propósito revisar el tema y recopilar las recomendaciones generales que todo dermatólogo debe conocer tanto en la fase preoperatoria, intraoperatoria, como postoperatoria al utilizar equipos de electrocirugía en un paciente con DECI.


Due to the accelerated population aging, an increa-sing number of users is carrying cardiac implantable electronic devices (CIEDs). Many of these patients will face dermatological procedures that often use electrosurgical equipment. The latter has the poten-tial to produce electromagnetic interference (EMI), and therefore alter the operation of these devices. While not all CIEDs have the same characteristics, new technologies for these devices have decreased if not eliminated completely the risk of EMI.The purpose of this article is to review CIED topic and compile general recommendations that every dermatologist should be aware of, both in the preoperative, intraoperative, and postoperative phases when using electrosurgery equipment in a patient with CIED.

ABSTRACT

Os gestores públicos ou privados são frequentemente pressionados para que tecnologias novas e emergentes na saúde sejam adquiridas, porém, para isso, processos de avaliação para sua incorporação, baseados em evidências científicas, tem sido cada vez mais essenciais, apesar do consenso sobre os inúmeros benefícios proporcionados. O Centro Cirúrgico representa uma unidade vital nas organizações de saúde, diferenciada no ambiente hospitalar, que concentra recursos humanos e tecnológicos altamente especializados, possibilitando uma assistência complexa e sofisticada. Porém, tal cenário demanda formação adequada dos profissionais de saúde, frente às habilidades e conhecimentos requeridos para utilização segura de tal parque tecnológico. A unidade de eletrocirurgia se constitui numa prática rotineira no período intraoperatório, requerendo conhecimento técnico-científico do equipamento e dos procedimentos, uma vez que eventos adversos relacionados a seu uso, como queimaduras, têm sido relatados. O treinamento e a capacitação dos profissionais, enquanto uma premissa na prevenção de acidentes, tem sido apontada como parte das boas práticas adotadas. Este estudo teve por objetivo avaliar o impacto de intervenções educativas no conhecimento e aplicabilidade de eletrocirurgia da equipe médicos residentes e de enfermagem. Trata-se de um quase experimento, com pré e pós-testes em um único grupo, num hospital de ensino de médio porte do interior de São Paulo. Participaram do estudo 4 médicos residentes da especialidade cirúrgica, 4 enfermeiros e 28 técnicos de enfermagem que atuavam com regularidade e frequência no centro cirúrgico. O estudo foi desenvolvido em sete etapas, com duração de 24 meses, sendo elaborado um questionário semi-estruturado para avaliação do conhecimento dos participantes em cada fase e um roteiro tipo check list para observação das práticas em sala cirúrgica, contendo indicadores relativos ao uso de eletrocirurgia. Os participantes foram expostos a duas intervenções educativas, sendo uma aula didática com disponibilização de um manual informativo e uma vídeoaula. Após cada intervenção, foram avaliados quanto a retenção do conhecimento, com intervalos de tempo programados previamente. Os resultados evidenciaram que os médicos residentes e enfermeiros apresentaram conhecimento prévio do tema em alguns tópicos específicos, não ocorrendo alteração de padrão de respostas. Entre os técnicos de enfermagem, observou-se melhora nos percentuais alcançados, com destaque para os itens checagem do equipamento e posicionamento da placa eletrodispersiva. Entretanto verificou-se que apesar do bom rendimento teórico, na prática os profissionais não apresentaram melhora da adesão de todos os indicadores. O posicionamento da placa adequado, ou seja, o mais próximo do sítio cirúrgico, porém distante o suficiente para evitar queimaduras, apresentou índices de conformidade inferiores a 50% em todas as fases do estudo. Pesquisas dessa natureza são oportunas pois proporcionam aos gestores uma possibilidade de propor projetos de melhoria continua da assistência perioperatória, que envolvam toda a equipe de profissionais, uma vez que a qualidade em saúde deve ser entendida como uma somatória de esforços conjuntos na busca por resultados eficazes, seguros e humanizados


Public or private managers are often pressured to acquire new and emerging health technologies; however, for this, evaluation processes for their incorporation based on scientific evidence have been increasingly essential, despite the consensus on the many benefits provided. The Surgical Center represents a vital unit in healthcare organizations, differentiated in the hospital environment, which concentrates highly specialized human and technological resources, allowing complex and sophisticated assistance. Nevertheless, this scenario requires adequate training of health professionals, facing the skills and knowledge required for safe use of such technology park. The electrosurgery unit is a routine practice in the intraoperative period, requiring technical-scientific knowledge of the equipment and procedures, since adverse events related to its use, such as burns, have been reported. The training and qualification of professionals, as a premise in the prevention of accidents, has been pointed out as part of the good practices adopted. This study aimed evaluate the impact of educational interventions on the knowledge and applicability of electrosurgery of the resident and nursing physicians. It is a quasi-experiment, with pre and post-tests in a single group, in a medium-sized teaching hospital in the interior of São Paulo state. Four resident physicians with surgical specialty, 4 nurses and 28 nursing technicians who worked regularly and frequently in the surgical center participated in the study. The study was developed in seven stages, with duration of 24 months, being developed a semi-structured questionnaire to evaluate the participants' knowledge in each phase and a check list type script to observe the practices in a surgical room, containing indicators related to the use of electrosurgery. The participants were exposed to two educational interventions, being one of them a didactic class with the provision of an informative manual and a video-class. After each intervention, the retention of knowledge was evaluated, with previously scheduled time intervals. The results showed that the resident physicians and nurses presented previous knowledge of the subject on some specific topics, and there was no change in the pattern of responses. Among nursing technicians, there was an improvement in the percentages reached, with emphasis on the items checking the equipment and positioning of the electrodispersive plate. However, it was verified that despite the good theoretical performance, in practice, the professionals did not show improvement of the adherence of all the indicators. The appropriate positioning of the plaque, i.e., the one closest to the surgical site, but far enough away to avoid burns, presented compliance rates lower than 50% in all phases of the study. Researches of this nature are necessary because it provides managers with the possibility of proposing projects for continuous improvement of perioperative care, involving the whole team of professionals, since health quality should be understood as a sum of joint efforts in the search for effective, safe and humanized results

ABSTRACT

PURPOSE: To investigate the clinical manifestations and properties of remnant particles in the subconjunctival space after high-frequency radio-wave electrosurgery for conjunctivochalasis. METHODS: We performed a retrospective, observational case series with in vitro experimental imaging in nine eyes from eight patients who presented with small dark-gray lesions during follow-up after high-frequency radio-wave electrosurgery for conjunctivochalasis. General examination including slit-lamp examination and visual acuity testing was performed preoperatively and postoperatively. During follow-up, we evaluated remnant particles and any other complications including granuloma or conjunctival injection with slit-lamp photography and anterior optical coherence tomography. Coagulation tips were investigated with scanning electron microscope and energy dispersive X-ray spectroscopy to analyze the insulating electrode and assess changes to tips after repeated use. RESULTS: None of the patients included in this study experienced any change in visual acuity or major complications postoperatively. Small dark-gray lesions (0.3 to 0.5 mm in size) were observed in the inferior bulbar sub-conjunctival space in the location where high-frequency radio-wave electrosurgery had been performed. Cirrus high-definition optical coherence tomography images revealed focal hyper-reflection with a posterior shadow, suggesting foreign particles. Scanning electron microscopy and energy dispersive X-ray spectroscopy imaging analysis revealed peaks of carbon and fluorine complexes, consistent with the polytetrafluoroethylene coating on the electrode. CONCLUSIONS: There were no instances of inflammatory reaction, particle migration, or major complications due to particles. Physicians should be aware of the possibility of remnant polytetrafluoroethylene particles in subconjunctival tissue when using insulated coagulation tips subjected to repeat sterilization.

ABSTRACT

PURPOSE: PEAK PlasmaBlade is a recent and distinctive type of electrosurgical device. Previous studies have already documented some meaningful advantages of this device over conventional electrosurgery. This study compared the use of PEAK PlasmaBlade to standard electrosurgery in mastectomy and breast conservative surgery. The purpose was to test the impact of PEAK PlasmaBlade on the wound-healing process and on postsurgical complications in breast cancer surgery. METHODS: Sixty patients undergoing breast cancer surgery were enrolled. The PEAK PlasmaBlade was used for 20 of those. A standard electrosurgical device was used for the other 40 patients. The 2 groups were homogenous in age, body mass index, comorbidities and type of surgery. We recorded wound complications, serum drainage amount and duration of stay, blood loss, time of surgery, length of hospital stay, and total number of medications required. RESULTS: The 2 groups were not significantly different in terms of patient characteristics. A statistically significant reduction in incidence of seroma was observed in the PEAK group: only 10% versus 37.5% of the patients in the conventional electrosurgery group developed this complication (Fisher exact test, P = 0.034). CONCLUSION: Seroma is the most important wound complication in breast surgery. The research of new instruments that might reduce its incidence is desirable. In order to validate or deny the results of this study, it is necessary to enroll more subjects and to consider the impact of this device on axillary lymph node dissection.

ABSTRACT

OBJETIVOS: En la actualidad, existe una alta tasa de sobre-tratamiento de lesiones precursoras cervicales, la cual, en su causalidad, depende de la inexperiencia del operador que toma las decisiones. El objetivo del presente trabajo fue desarrollar un método estandarizado de ponderación/juicio de variables diagnósticas y tratamiento útiles de ser usadas por especialistas jóvenes a fin de minimizar el riesgo de manejo inadecuado. MATERIALES Y MÉTODOS: Se incluyeron 471 pacientes referidos por citología anormal y tratados mediante asa de LEEP. Se calcularon la sensibilidad, la especificidad, los valores predictivos y las relaciones de probabilidad para el diagnóstico de NIE2+ para cada uno de los métodos de diagnóstico. A cada residente se le enseñó un protocolo estandarizado de tratamiento mediante asa. Una vez identificados los mejores predictores, se construyó una escala de puntaje que ponderaba las variables y se definió mediante curva ROC el major punto de corte para la predicción de NIE2+. Las diferencias entre los grupos se compararon mediante Chi-cuadrado, ANOVA o t-test. Se construyó curva de fallas mediante el método de 1-Kaplan Meier. RESULTADOS: La prevalencia de NIE2+ en esta cohorte fue 66%. La concordancia entre las pruebas diagnósticas fue baja, teniendo la colposcopia el peor valor predictivo positivo y el mayor riesgo de sobre-tratamiento. Para la escala de puntaje se incluyeron la edad, la citología, la colposcopia (estratificación basada en la extensión de compromiso por cuadrantes), la biopsia por mascada y la concordancia entre pruebas diagnósticas. Un puntaje≥ 9 asociado al uso de un protocolo estandarizado, obtuvo tasas de sobre-tratamiento <15%, de recurrencias de NIE2+ <5% a 5 años y una baja tasa de procedimientos sub-óptimos o con complicaciones (<2 %). CONCLUSIONES: El método CONO-UC al combinar un sistema de puntaje integrado (punto de corte) con un protocolo estandarizado de excisión, permite minimizar el riesgo de sobretratamiento o tratamiento inadecuado, por parte de especialistas jóvenes, de lesiones preinvasoras del cuello uterino, reduciendo además el número de procedimientos indicados innecesariamente y manteniendo una alta tasa de éxito terapéutico.


GOALS: Currently, there is a high rate of over-treatment of precursor cervical lesions, which, in their causality, depends on the inexperience of the decision-making operator. The objective of the present study was to develop a standardized method of weighting / judgment of diagnostic variables and treatment useful to be used by young specialists in order to minimize the risk of improper handling. MATERIAL AND METHODS: We included 471 patients referred by abnormal cytology and treated by LEEP. Sensitivity, specificity, predictive values and likelihood ratios for the diagnosis of CIN2+ were calculated for each of the diagnostic methods. Each resident was taught a standardized protocol to carry out a LEEP procedure. Once the best predictors were identified, a scoring scale was constructed that weighted the variables and the best cut-off point for the prediction of CIN2+ was defined by ROC curve. Differences between groups were compared using Chi-square, ANOVA or t-test. Failure curves were built up using the 1-Kaplan Meier method. RESULTS: The prevalence of CIN2+ in this cohort was 66%. The agreement between the diagnostic tests was low, with colposcopy having the worst positive predictive value and the highest risk of over-treatment. Age, cytology, colposcopy (stratification based on the extent of compromise by quadrants), punch biopsy, and agreement between diagnostic tests were included for building the scoring scale. A score ≥ 9 in association with the use of a standardized protocol obtained rates of over-treatment <15%, recurrences of CIN2+ <5% at 5-year follow-up and a low rate of suboptimal procedures or complications (<2%). CONCLUSIONS: The UC-CONE method, by combining an integrated scoring system with a standardized excision protocol, minimizes the risk of over-treatment or inadequate treatment of pre-invasive cervical lesions by young specialists, reducing the number of procedures indicated unnecessarily and maintaining a high rate of therapeutic success.

ABSTRACT

Abstract Electrosurgery is a technology developed over the last few years and has become a very important tool in modern surgery. Most of the equipment is considered safe, although there are risks related to its use. Several lesions may be caused by electrocautery, and burns are the most common and feared. We report two cases of burns related to use of electrocautery and promote a literature review, because knowledge of electrosurgery fundamentals, its correct use, the choice of a safety device, constant monitoring, and immediate investigation before any suspicions surely can improve the operational experience for both surgeon and patient.


Resumo A eletrocirurgia é uma tecnologia que se desenvolveu muitos nos últimos anos e se tornou um instrumento de grande importância na cirurgia moderna. A maioria dos equipamentos é considerada segura, embora existam riscos relacionados ao seu uso. Várias lesões podem ser causadas por eletrocautérios, as queimaduras são as mais frequentes e temidas. Relatamos dois casos de queimaduras relacionadas ao uso do bisturi elétrico e promovemos uma revisão de literatura, pois o conhecimento dos fundamentos da eletrocirurgia, seu uso correto, a escolha de um equipamento seguro, o monitoramento constante e a investigação imediata diante de quaisquer suspeitas com certeza podem melhorar a experiência operacional para ambos, cirurgião e paciente.

ABSTRACT

Objetivou-se identificar concentrações de hidrocarbonetos policíclicos aromáticos provenientes da fumaça do eletrocautério nas salas operatórias, correlacionando estas concentrações com o tempo de uso do eletrocautério e cirúrgico. Trata-se de um estudo de campo, transversal e quantitativo, realizado em 50 atos cirúrgicos do aparelho digestivo, entre abril e julho de 2015, em hospital universitário no estado do Paraná. Foram coletados hidrocarbonetos por meio de uma bomba de sucção e determinados por cromatografia liquida. Estes compostos foram encontrados com média de 0,0058 mg.m-³ e mediana de 0,0049 mg.m-³. O tempo médio cirúrgico e de uso do eletrocautério foram de 136 minutos e 220,5 segundos, respectivamente. O teste de correlação de Spearman foi de -0,512 entre as variáveis concentrações e tempo cirúrgico e de -0,183 entre as concentrações e tempo de uso do eletrocautério. Conclui-se que existem hidrocarbonetos e há baixa correlação entre a produção destes compostos e tempo de uso do eletrocautério (AU).


The objective was to identify concentrations of polycyclic aromatic hydrocarbons produced by electrocautery smoke in operating rooms, correlating these concentrations with time of electrocautery and surgical use. This is a cross-sectional and quantitative field study carried out in 50 gastrointestinal surgical procedures, between April and July 2015, in a university hospital in the state of Paraná. Hydrocarbons were collected using a suction pump and measurements were determined through liquid chromatography. These compounds were found to have an average of 0.0058 mg.m-3 and a mean of 0.0049 mg.m-3. The mean surgical time and electrocautery use were 136 minutes and 220.5 seconds, respectively. The Spearman correlation test was -0.512 between concentration variables and surgical time, and -0.183 between the concentrations and electrocautery use. The conclusion was the presence of hydrocarbons and a low correlation between the production of these compounds and the electrocautery usage time (AU).

ABSTRACT

El láser como alternativa a la cirugía abierta de la vía aérea superior ha venido a modificar la forma de abordaje de las patologías en esta área, pero no deja de ser un procedimiento costoso que no está al alcance de todos los servicios. Por este motivo se han reinventado nuevas formas de abordaje que cumplan los mismos requisitos tanto de la cirugía abierta como con láser pero con un menor coste. Presentamos una serie de 30 casos realizados en un período de 6 años por motivos tanto tumorales como no, en los que se realizaron abordajes cerrados a través de microcirugía con disección mediante microelectrodos. Obteniendo pocas complicaciones y una disminución de la estancia hospitalaria significativa. Con lo cual nos parece una técnica eficiente para abordajes de este tipo.


The laser as an alternative to open surgery of the upper airway has come to change the form of approaching the disease in this area, but it is still an expensive procedure that is not available to all services. For this reason a new ways of approach to meet the same requirements both open as laser but at a lower cost surgery. We present a series of 30 cases performed over a period of 6 years for reasons as much tumor, which closed approaches through microsurgical dissection were performed using microelectrodes. Obtaining few complications and significant decreased hospital stay. Our considerations is it seems an efficient technique for such approaches.

ABSTRACT

Abstract Objective To evaluate the expressions of biomarkers p16 and Ki-67 in low-grade (LG) or high-grade (HG) lesions, and to relate them to risk factors and the recurrence of these lesions. Methods A retrospective case-control study of 86 patients with LG and HG lesions who underwent a loop electrosurgical excision procedure (LEEP) between 1999 and 2004. The control group was composed of 69 women with no recurrence, and the study group, of 17 patients with recurrence. All patients were followed-up over a two-year period after surgery, and screened every six months, including cytology and colposcopy. Biopsy samples collected from LEEP were submitted to immunohistochemical analysis for p16 and Ki-67. The statistical analysis was performed using the Statistical Package for the Social Sciences software (SPSS, IBM-SPSS, Inc., Chicago, IL, US), with a significant p < 0.05. Results The biomarkers p16 and Ki-67, separately or combined, showed no relation to recurrence on the total analysis. However, evaluating specifically HG lesions, the positive expression (2+ and 3 + ) of p16/Ki-67 was associated with recurrence (0.010). In addition, p16 isolated was also more expressive in HG lesions (2+ and 3 + , p= 0.018), but it was unrelated to recurrence. Conclusion Proteins p16 and Ki-67, both isolated and combined, are not reliable primary markers for the recurrence of cervical lesions in the majority of LG lesions. However, analyzing only the group with prior diagnosis of HG lesions, the expressions of p16 and of p16/Ki-67 were associated with recurrence, and they may be useful in monitoring these cases.


Resumo Objetivo Avaliar as positividades dos biomarcadores p16 e Ki-67 em lesões de baixo grau (BG) ou de alto grau (AG), e relacioná-las com os fatores de risco e com a recidiva dessas lesões. Métodos Estudo retrospectivo caso-controle, com 86 pacientes com lesões de BG e AG, submetidas à conização por cirurgia de alta frequência entre 1999 e 2004. O grupo de controle foi constituído de 69 mulheres sem recidivas, e o grupo de estudo, de 17 pacientes que recidivaram. Todas as pacientes foram acompanhadas durante dois anos após a cirurgia, com controle a cada seis meses, incluindo citologia e colposcopia. As peças provenientes de cirurgia de alta frequência (CAF) foram submetidas a imunohistoquímica para p16 e Ki-67. A análise estatística foi realizada com o programa Statistical Package for the Social Sciences (SPSS, IBM-SPSS, Inc., Chicago, IL, EUA), com p significante quando < 0,05. Resultados Isoladamente ou em conjunto, p16 e Ki-67 não se relacionaram com as recidivas quando analisados na totalidade dos casos. Entretanto, avaliando especificamente as lesões de AG, a positividade (2+ e 3 + ) do conjunto p16/Ki-67 foi relacionada com recidiva (0,010). No mais, p16, isoladamente, foi também mais expresso nas lesões de AG (2+ e 3 + , p= 0,018), mas sem relação com recidiva. Conclusão Quando testadas na totalidade dos casos, as proteínas p16 e Ki-67, separadas ou em conjunto, se mostraram ineficientes como marcadores primários de recidiva de lesões precursoras. Entretanto, quando avaliadas somente no grupo diagnóstico prévio de lesão de AG, as expressões das proteínas p16 e p16/Ki-67 têm relação com a recidiva, e podem ser úteis no acompanhamento desses casos.
