Objectives. Endoscopic gastrostomy occasionally presents limitations such as costs, availability of equipment and special materials, and difficult access to the gastric cavity in the setting of obstructive esophageal tumors. Open jejunostomies present high rates of postoperative complications and limited capacity for abdominal evaluation due to reduced incision size. Thus, to reduce procedure-related complications and overall costs and provide a thorough intraoperative evaluation of the peritoneal cavity, we present the following simplified technique. Methods. Video-assisted jejunostomy in ten steps. Results. The use of this Video-assisted laparoscopic technique proves to be a safe, viable alternative, with cost reduction, decreased use of disposable materials, shortened operative time, and accelerated recovery, in addition to increased technical ease and wide applicability across a variety of hospital settings.

Hepatocellular carcinoma (HCC) is the most frequent primary malignant liver tumor, with more than 800,000 new cases diagnosed each year and with high mortality, ranking fourth in the world in cancer deaths. The worst prognosis is related to the late diagnosis, in which the tumor is at an advanced stage and curative treatments are not efficient in terms of increasing overall survival. Currently, screening and monitoring tests based on current guidelines have limited accuracy, which points to the need for the development of new biomarkers that improve HCC detection as well as its early diagnosis. This review will discuss the five phases of development of a biomarker, from its discovery to its application in clinical practice, and indicate the main biomarkers per development phase. Potential emerging technologies such as "Radiomics", "Proteomics" and "Metabolomics" will also be discussed, which should serve as tools for the elucidation of tumor heterogeneity, as well as provide data for future studies on HCC biomarkers.

Background Hepatic metastasis are frequent and liver resection may be an option for some cases, despite the high complexity of the procedure and the possibility of postoperative complications. Methods This retrospective comparative descriptive study aims to evaluate a series of 86 consecutive liver resections (LRs) performed for the treatment of metastatic liver tumors, comparing the results between patients undergoing major and minor LR. All patients submitted to LR from October 2010 to July 2015 at the Erasto Gaertner Hospital in Curitiba-PR were included. Quantitative numerical variables were analyzed with the Student t-test. The nonparametric Mann–Whitney U test was used for numerical variables of non-normal distribution. Categorical variables were analyzed with the Chi-square test with Fisher's correction. The data were analyzed with the SPSS 23.0 and STATA 15 programs, being p Results Eighty-six LR were performed, 56 cases by colorectal metastasis. The major LR corresponded to 68 cases, with 13.2% of Clavien-Dindo III–V complications and 2.9% of reoperation rate. Eighteen minor LR were performed and one patient had a postoperative complication requiring reoperation. Conclusion Preoperative elevation of transaminases and jaundice negatively influence surgical outcomes in patients undergoing LR. Tumors greater than 3 cm presented worse postoperative survival. Major LR did not significantly increase the surgical morbidity rate. Institutional Review Board registration 1.122.319/2015

Quality is a term used by various specialists, from different perspectives, having as a common point to identify focuses that promote their development in institutional management. Quality processes allow us to improve assistance, reducing complication and death rates and reducing costs. Currently, the positive experience of the patient is highly valued and should be sought by all institutions. The benefits of quality procedures are extensive. There is evidence of lower complication and mortality rates, cost reduction, uniformity of care, improved communication and opportunity for health education. There is a need for financial investment by the institutions, but they can be converted in the future. The idea that these are just bureaucratic steps must be fought because individualistic attitudes are no longer part of safe medicine. The success of a quality process requires interdisciplinarity, integration with quality offices for effective communication. The implementation of feasible attitudes should be sought, with a high adherence rate to seek patient satisfaction and safety. We will address historical aspects, the requirements for the implementation of a quality program, the concepts of indicators and the aspects that influence the quality in surgery, in addition to presenting benefits that such a program can offer to the surgeon and the institution.

Objective: to appraise the general profile of the Brazilian robotic surgeon and the acknowledgment of the new certification process for robotic surgery upon the Associação Médica Brasileira (AMB - Brazilian Medical Association) statement. According to the AMB statement, medical societies and proctors have to achieve leading roles in training and certification of surgeons, acting in partnership with industry. Methods: a national web-based survey was promoted by the Colégio Brasileiro de Cirurgiões (CBC - Brazilian College of Surgeons) among their members. Results: the 294 answers were split into two groups: 133 (45.3%) who had robotic console certification, and 161 (54.8%) who did not have it. The overall median age was 46, but the non-robotic group presented more surgeons with at least 30 years of experience than to the robotic group (32.3% versus 23.3%, p=0.033). Surgeons with robotic certification more frequently work in a city with at least one million inhabitants than surgeons who were not certified (85.7 versus 63.4%, p

The main objectives of emergency department thoracotomy (EDT) are to avoid the cardiovascular collapse from mechanical sources or extreme hypovolemia, in patients in extremis. The indication is to perform in patients presenting pulseless with signs of life, pulseless electrical activity (PEA), sudden cardiac arrest (SCA), or imminence of SCA (profound refractory shock). It must be remembered to avoid in patients with isolated cranial injuries. The best timing of closed-chest CPR plausible to start the thoracotomy is 15 minutes for penetrating traumas and 10 minutes for blunt traumas.

Damage control surgery (DCS) is an abbreviated laparotomy for patients who have life-threating bleeding, injuries, and septic sources. The procedure consists of hemorrhage control, by procedures like hemostasis, packing, clamping, and ligation; limits contamination by simple resections, primary suturation, closed absorbent systems, and external drainage; and leads to temporary abdominal closure as quickly as possible. The non-life-threatening injuries are delayed to a reoperation. The main purpose of the damage control surgery is to prevent complications of the lethal triad: coagulopathy, acidosis, and hypothermia.

The injury severity scores can estimate the prognosis and risk of complications after a trauma. They serve as important adjuncts in triage, patient care, and research. Furthermore, they can be used for evaluation of hospital resource utilization and cost-effectiveness studies in trauma. They consist of complex mathematical equations in which variable qualitative and quantitative data are standardized and transformed into a single value, which represents the clinical conditions and prognosis of the patient shortly after injury.

Objective To evaluate the perception of doctors, residents, and medical students of smartphone use on daily medical practice. Materials and methods Cross-sectional study with data collected online by questionnaire on Google Docs®, with closed multiple-choice questions regarding smartphones use in medical practice and its impact on decision-making and patients' privacy. Results There were 118 questionnaires, mostly from students (61%), followed by medical residents (31%) and medical preceptors (8%). All preceptors confirmed eventual use of smartphones on clinical cases discussions, 77.8% of whom use it in less than half of the time. Among the residents, 94.6% use theirs smartphones, 77% of them in more than half of the time. On the contrary, 12.5% of the students do not use this kind of resource, and among those that do use it, 50% do so more than half of the time. All preceptors, 94.6% residents and 80.6% of the students believe its use does not expose the patients' privacy. Conclusion Preceptors and residents use smartphones more often than medical students. Most agree its use helps on daily decision-making and does not jeopardize the patients' privacy.

Background It is not always that prehospital trauma life support (PHTLS) principles are applied to daily practice. Lack of training to health care providers and a high amount of patients overwhelming the system capacity may let malpractice behavior to happen. It is the aim of this study to assess injuries misdiagnosed by prehospital trauma care in a capital city in southern Brazil. Study design A prospective observational non-controlled study with 174 random trauma cases that were brought to a level 1 trauma center in the city of Curitiba, between May 28th and June 10th 2006. We analyzed data registered in the prehospital rescue team form. The including criteria were all patients delivered to the trauma center by ambulances. The excluding criteria were patients not transported by ambulances and those without the proper form filled out. Statistical analysis was performed using the Chi-square for discrete, and the students’ t-test for continuous variables. Results Of the 174 patients who met the including criteria, 75% were men with a mean age of 27-year-old. Of the 11 injuries to the neck identified in the Hospital evaluation, eight were missed by the prehospital care (OR 0.26 CI 95% 0.07-0.94). Also, only 7/20 injuries to the back were identified by the PHTLS team (OR 0.32 CI 95% 0.13-0.78). Similarly, only 6/26 injuries to the chest (OR 0.20 CI 95% 0.08-0.50), 4/15 to the abdomen (OR 0.24 CI 95% 0.08-0.76), 4/16 to the pelvis (OR 0.23 CI 95% 0.07-0.70), 13/33 to the upper body (OR 0.34 CI 95% 0.17- 0.68),7/39 to the lower body (OR 0.14 CI 95% 0.06-0.33) and 17/55 (OR 0.23 CI 95% 0.12-0.42) were correctly identified in the prehospital scenario. Conclusion Although it is known PHTLS principles, which save lives when applied in practice, further training and remarks to its importance is needed to fully implement efficient trauma systems. Electronic data collection shall make checklists consistently filled out, so that patient care will be improved. How to cite this article Abreu-Reis P, Nasr A, Tomasich FS, Collaco I.

BackgroundTrauma registry remains a great problem to most countries that are implementing trauma systems. Nondigital data assessment and storage may lead to information deterioration along the process. In order to verify the missing registry in prehospital trauma rescuers’ form, we ran this study.Study designA prospective observational noncontrolled study with 288 random trauma cases brought to a Level 1 Trauma Center in Curitiba, between May 28th and June 10th 2006. We analyzed data registered in the prehospital rescue team form. The including criteria were all patients delivered to the trauma center by ambulances. The excluding criteria were patients not transported by ambulances and those without the proper form filled out. Statistical analysis was performed using the Chi-square for discrete, and the student's t-test for continuous variables.ResultsTwo hundred and eighty-eight trauma cases were observed. Twelve patients were excluded. Of the 276 patients who met the including criteria, 75% were men with a mean age of 27-year-old. In only 8.34% of times patients were brought by doctors, while in 91.66% by paramedics. 63.4% of patients were traffic injuries victims, followed by 12.31% falls, 6.52% falls from the high, 5.79% gunshot wounds, 5.34% assaults, 3.62% stab wounds, 2.89% others. Impressively, 16 patients (5.89%) had no records of respiratory rate from the prehospital care assessment, 20 (7.24%) had no data of systolic blood pressure and 13(4.71%)had no pulse registry. Furthermore, 31.25% of the RR not registered were abnormal in the hospital admission evaluation, as well as 15% of the SBPs, and 23% of HR. None of the cases had information regarding time from the scene to the hospital.ConclusionElectronic data collection shall make checklists consistently filled out. It is not well understood the importance of registering data for most of healthcare providers working in the field, especially when they do not follow the in-hospital care of trauma patients.How to cite this articleAbreu-Reis P, Tomasich FS, Nasr A, Collaco I.

Objective: Io evaluate the expression of p16INK4a and p53 biomarkers in conization specimens from patients with high grade cervical intraepithelial neoplasia (HG-CIN), correlating them with the ability to predict the recurrence. Methods : we conducted a retrospective study of patients with HG-CIN in cervical biopsy treated with conization between January 1999 and January 2006 who had a minimum follow-up of 18 months. The expression of the p16 and p53 was assessed by tissue microarrays and correlated with disease recurrence. For analysis, we used the test of proportions (chi-square), considering value p0.05). p53 had a positive predictive value (PPV) of 42% and negative predictive value (NPV) of 73%, sensitivity 70%, specificity of 47% and accuracy of 59%. The p16, PPV 42%, NPV 72%, sensitivity 66%, specificity of 49% and accuracy of 56%. Conclusion : immunohistochemistry expression of p53 and p16 showed low sensitivity and low specificity as predictors of HG-CIN recurrence after conization treatment. Objetivo : avaliar a expressão dos biomarcadores p16INK4a e p53, nas peças de conização de pacientes com neoplasia intraepitelial cervical de alto grau (NIC-AG), correlacionando com a capacidade de predizer o risco de recorrência. Métodos : estudo retrospectivo de pacientes com NIC-AG em biópsia de colo uterino, tratadas por conização, entre janeiro de 1999 e janeiro de 2006 e seguimento mínimo de 18 meses. A expressão dos biomarcadores p16 e p53 foi avaliada através de técnica de microarranjos teciduais e correlacionada com a recorrência da doença. Para análise utilizou-se o teste das proporções (qui-quadrado), considerando valor p0,05). O p53 apresentou valor preditivo positivo (VPP) de 42% e valor preditivo negativo (VPN) de 73%, sensibilidade de 70%, especificidade de 47% e acurácia de 59%. O p16, VPP de 42% e VPN de 72%, sensibilidade de 66%, especificidade de 49% e acurácia de 56%. Conclusão : a expressão imunoistoquiímica do p53 e do p16 apresentaram baixa sensibilidade e baixa especificidade como marcadores capazes de predizer a recorrência da NIC-AG tratada por conização.

Background Traffic injuries are among the main causes of death worldwide. Even with the advances in technology, there are still 50% of deaths that cannot be reduced by medical care improvement. These important injuries can though be reduced by prevention of trauma. One of the best ways to address this issue is through incorporating preventive measures to the daily routine of schools. It is the aim of this study to assess children's perception on traumatic events and to introduce a cost-effective peer-education preventive action. Study design A prospective interventional comparative study with children from a basic school in South Brazil. A questionnaire with 9 decision-making questions about traffic scenarios was applied by volunteer medical students from May to June 2012, before and after a peer-educational lecture on prevention of traffic injuries. There were 20 epidemiological questions as well. Data collected was compared between the pre and the posttests of the same students. Statistical analysis was performed using the Chi-square for discrete, and the students’ t-test for continuous variables. Results Among 246 students answered the questionnaires. The mean age was 10.19 years old. 21% reported that always crosses the street alone, while 47% only cross with an adult. Most of the students said they always cross-streets in the zebra-crossing and look to both sides before crossing (60.71 and 84.9% respectively). Impressively, 12.55% said they often/ sometimes drive a car or a motorcycle. Also, 30.76% ride a bike in between the cars. Furthermore, 77.48% of the students use the front seat of the car. Regarding safety issues, only one-third have a horn in their bikes, and less than half use helmet when playing. When comparing their assessments, there was a higher number of correct answers in the decision-making section in the post-test (5.21 vs 3.93, p = 0.000001161). The estimated overall cost was 45 dollars. Conclusion Preventive measures urge to be incorporated to schools curricula. Peer-educational actions are a cost-effective for spreading medical knowledge among children and youth.

O leiomiossarcoma da glândula adrenal é uma neoplasia extremamente rara, cuja origem provém da veia central da adrenal ou de suas tributárias. Estes tumores são vistos com incidência aumentada em pacientes infectados pelo vírus da imunodeficiência humana adquirida (HIV) e também pelo vírus Epstein-Barr (EBV). Relata-se o caso de uma paciente de 48 anos diagnosticada, por meio de exames de imagem, massa ocupando loja adrenal esquerda, próxima ao pâncreas. Foi submetida à ressecção cirúrgica com achados histopatológicos e imunohistoquímico compatíveis com leiomiossarcoma primário de adrenal. A paciente foi a óbito após 53 meses da adrenalectomia. Concluiu-se que, não obstante a raridade desta neoplasia, sabe-se que, bem como os demais sarcomas de partes moles, o leiomiossarcoma de adrenal se comporta de maneira agressiva e tem na adrenalectomia o tratamento de escolha, não sendo necessário o emprego de quimio ou radioterapias de rotina, exceto em doença metastática ou irressecável.

OBJETIVO: Analisar a incidência das complicações pós-operatórias das colecistectomias por via aberta e laparoscópica, em relação ao sexo. Método: Estudo retrospectivo de 1123 pacientes submetidos a colecistectomia eletiva, por via aberta ou laparoscópica, no Departamento de Cirurgia da Santa Casa de Misericórdia de São Paulo, no período de Janeiro/1997 a Janeiro/2001. Foi realizada uma avaliação comparativa das complicações pós-operatórias, relacionando os resultados com a idade, ASA, via de acesso, tempo de cirurgia, acidentes intra-operatórios, necessidade de drenagem, período de permanência hospitalar, resultado anátomo-patológico e mortalidade. RESULTADOS: Houve predominância do sexo feminino na população estudada, com 82,5% dos casos. A média de idade foi de 48,8 anos (14 a 97 ). Das operações realizadas, 693 (61,7%) foram por via laparoscópica, sendo a maior proporção de abordagens abertas no sexo masculino (p=0,0014). A taxa global de conversão foi de 2,31%, sem diferença entre os sexos, assim como a realização de procedimentos associados e a ocorrência de acidentes intra-operatórios. A duração da intervenção, a drenagem, a permanência hospitalar pós-operatória, complicações e mortalidade foram significativamente mais freqüentes entre os homens. Neste grupo, observou-se duração maior do ato operatório e permanência hospitalar pós-operatória, com significância estatística, principalmente quando se realizou o tratamento tradicional. CONCLUSÕES: O sexo masculino mostrou-se como provável fator de risco para complicações nas colecistectomias, resultando em operações prolongadas, maior período de permanência hospitalar, necessidade de drenagem mais freqüente e mortalidade elevada em relação ao sexo feminino.

OBJETIVOS: Avaliar a influência do tratamento neoadjuvante (quimioterápico e/ou radioterápico) nas complicações pós-operatórias e letalidade hospitalar de pacientes com câncer de esôfago submetidos a esofagectomia com linfadenectomia em dois campos. MÉTODOS: Estudo retrospectivo de 132 pacientes com câncer de esôfago admitidos no Departamento de Cirurgia do Hospital Erasto Gaertner de janeiro de 1987 a janeiro de 1998, divididos de acordo com a realização ou não de tratamento neoadjuvante. Analisaram-se as variáveis relativas ao paciente (sexo, idade, estado geral, perda ponderal, co-morbidades, tabagismo, risco pulmonar), ao tumor (tipo histológico, localização, estádio clínico) e ao procedimento cirúrgico (local e tipo da anastomose, tempo cirúrgico, tempo de permanência hospitalar), relacionando-as com as complicações e mortalidade pós-operatórias. RESULTADOS: Noventa e quatro pacientes (71,2%) eram do sexo masculino. O tipo histológico predominante foi o CEC em 94,7% e oito pacientes (66,6%) eram tabagistas, e as principais co-morbidades anotadas foram: DPOC (29,55%) e HAS (15,15%). A principal localização do tumor foi o segmento torácico inferior (56,06%), com extensão tumoral média de 47,72 (8-70) mm. Seis pacientes (4,54%) eram EC I, 44 (33,33%) IIA, 24 (18,18%) IIB, 38 (28,80%) III e 17 (12,90%) IV. Quanto ao tratamento neoadjuvante, 39 pacientes (29,54%) foram submetidos a quimioterapia e 22 (16,67%) a radioterapia. As complicações pós-operatórias foram de 74,35% (p=0,0002) e 72,73% (p=0,0037), respectivamente. A taxa de complicações foi de 39,3% e a letalidade hospitalar 13,70%, representadas mais freqüentemente pelas causas pleuropulmonares. CONCLUSÕES: O tratamento neoadjuvante quimioterápico e radioterápico foi relacionado com maior ocorrência de complicações pós-operatórias, sem influência na letalidade hospitalar.

Objetivo: avaliar a correlação entre o nível sérico do CEA e CA 72-4 com a profundidade de invasão e estadiamento das neoplasias gástricas. Material e Métodos: foram avaliados pacientes com adenocarcinoma gástrico admitidos no Serviço de Cirurgia Abdominal do Hospital Erasto Gaertner no período de janeiro de 1996 a janeiro de 2000, incluindo-se neste estudo os pacientes que apresentavam dosagem sérica pré e pós-operatória de pelo menos um dos marcadores (CEA e/ou CA 72-4) e apresentavam estadiamento patológico ou evidências de doença disseminada pelos métodos de imagem. Resultados: dos 144 pacientes elegíveis, 71% eram do sexo masculino. A média de idade foi de 59 anos. O CEA mostrou-se alterado em 66,2% dos casos, e em 70,3% dos casos na análise do CA 72-4. Quanto à profundidade de invasão, o tumor invadia até a camada mucosa em apenas sete (4,8%) pacientes, até a camada submucosa em oito (5,6%) pacientes, muscular em 34 (23,6%), serosa em 45 (31,3%) e órgãos adjacentes em 33 (22,9%) dos casos. Em 17 pacientes a profundidade de invasão não foi avaliável, embora já fosse definida a doença como disseminada por outros meios. Na análise comparativa dos níveis séricos do CEA e do CA 72-4, de acordo com a profundidade de invasão, não observamos significância estatística para positividade dos marcadores nos tumores gástricos. Conclusões: no presente estudo, os marcadores séricos CEA e CA 72-4 não se mostraram como fatores preditivos para profundidade de invasão e estadiamento nos pacientes com câncer gástrico.

Made available in DSpace on 2022-04-29T08:44:48Z (GMT). No. of bitstreams: 0 Previous issue date: 2013-12-01 Objective: To define the epidemiological characteristics of patients during follow-up after initial care of a traumatic skin wound in the emergency room and to correlate this with literature data. Method: Across sectional prospective observational study. Patients with traumatic wounds treated in the emergency room were given 2 questionnaires: a questionnaire regarding factors that influence the healing process and a second questionnaire, given between 7 and 10 days later, about the care of the site, degree of healing and signs of infection. Results: From the initial sample of 47 patients only 25 patients completed and returned to the second evaluation. Half of patients had not completed high school. Most common wounds were related to sharp objects (68%). One in every three injuries involved the hand; and of these, 92% were work related. The scalp was affected in 23% and the face in 21% of cases. Twenty percent of patients had returned with signs of infection, compared to the literature showing a rate of 3.5%. Eighty percent of patients with wound infection denied any related health conditions. Conclusion: This population showed a low level of education, which may be a factor in poor understanding and care of the wound. The most common location of the wound was the head (scalp and face) followed by the upper extremities (especially hands). Considering the epidemiology and mechanisms of trauma frequently experienced in our environment, prevention can be cost-effective and decrease morbidity. Follow up is a potential source of bias since patients may be motivated to attend this service based on how they perceive abnormal wound healing. This work shows the importance of many factors related to traumatic wound care but it is essential that the investigation be expanded. © 2013 Strack Neves GC, et al.

Introdução: globalmente, são diagnosticados mais de meio milhão de casos de carcinoma hepatocelular (CHC) ao ano. É o terceiro câncer em mortalidade e o sexto em incidência. Os fatores de risco são bastante conhecidos e descritos na literatura - a cirrose, o principal deles, é encontrada em 90% dos casos. Em termos globais, a etiologia mais comum é o vírus da hepatite B (HBV), seguido do vírus da hepatite C (HCV). Material e métodos: realizada uma busca na base de dados do Medline a partir da ferramente MeSH do site Pubmed no dia 11 de março de 2014. Foram usadas como palavras-chave: “carcinoma hepatocellular/epidemiology”. Restringindo a revisões sistemáticas ou revisões publicadas nos últimos 5 anos, foram encontrados 154 artigos. A partir da leitura do título e abstract, o número foi reduzido a 52. Adicionalmente, incluímos artigos referenciados nos trabalhos selecionados. Resultados e Discussão: a distribuição do CHC no mundo é bastante heterogênea e dinâmica. Oitenta e dois por cento dos novos casos concentram-se em países em desenvolvimento, com a China contemplando sozinha 55%. Localidades de alta incidência de CHC normalmente são endêmicas para o HBV. Já em regiões de baixa incidência para o câncer, a etiologia predominante é o HCV. Somados, os vírus são encontrados em 80% de todos os casos. Outra característica é o maior comprometimento de homens – no Brasil, 78%. Os fatores de risco, além dos vírus, são o etilismo, hemocromatose, aflatoxina B1, hepatite autoimune, obesidade, Diabetes, Doença Hepática Gordurosa Não-Alcoólica (NALFD), Esteatohepatite Não-Alcoólica (NASH) e tabagismo.

OBJETIVO: Avaliar as indicações, sobrevida e fatores prognósticos da esofagogastrectomia com linfadenectomia em dois campos no câncer do esôfago torácico. MÉTODOS: Foram avaliados 111 pacientes retrospectivamente no período de janeiro de 1990 a dezembro de 2001 sendo 83 homens e 29 mulheres. A idade média dos pacientes foi 55,1 anos (variando entre 35-79). A linfadenectomia em dois campos foi parcial (Standard) em 34 pacientes(30,6%) e ampliada em 77(69,4%). RESULTADOS: A média de linfonodos dissecados foi de 22,6(variando entre 4 e 50). A doença R0 ocorreu em 53 pacientes(47,7%) a doença residual microscópica (R1) em 57 (52,3%) e a doença residual R2 em um paciente(0,9%). A recidiva ocorreu em 32 pacientes (28,8%) sendo em sete (6,3%) cervical, 17 (15,3%) locorregional e 19 (17,1%) sistêmica. A morbidade e mortalidade pós-operatória foram de 31,5% e 9% respectivamente, sem diferença significativa em relação á extensão da linfadenectomia mediastinal. A sobrevida global dos 111 pacientes em cinco anos foi de 48,4%, sem diferença significativa na sobrevida em relação á extensão da linfadenectomia, porém, houve aumento significativo na sobrevida livre de doença a favor dos paciente submetidos a linfadenectomia mediastinal ampliada(p=0,01). A ausência de doença residual (R0), comprometimento linfonodal (pN0) e o número de linfonodos comprometidos inferior a quatro, indicaram bom prognóstico. CONCLUSÃO: A esofagogastrectomia com linfadenectomia em dois campos apresentou um impacto positivo na taxa de sobrevida em cinco anos nos pacientes com câncer do esôfago torácico, particularmente em relação aos pacientes com ECIII. A linfadenectomia mediastinal ampliada aumentou significativamente a sobrevida livre de doença. BACKGROUND: To evaluate the indication, survival and prognostic factors of esophagogastrectomy with two-field lymphadenectomy in thoracic esophageal carcinoma. METHODS: From January 1990 to December 2001, 111 patients were retrospectively analyzed. There were 83 men and 29 women. Median age was 55,1 years (range 35-79). Partial( standard) mediastinal lymphadenectomy was performed in 34 patients (30,6%) and extended lymphadenectomy in 77(69,4%). RESULTS: The median number of dissected lymph node was 22,6(range 4-50). No residual disease(R0) was found in 53 patients(47,7%), microscopic residual disease(R1) in 57(52,3% and macroscopic residual disease(R2) in 1(0,9%). Recurrence occurred in 32 patients(28,8%): cervical in 7(6,3%), locoregional in 17(15,3%) and distant in 19(17,1%). Operative morbity and mortality were 31,55 and 9% respectively with no significant difference between partial(standard) and extended mediastinal lymphadenectomy. The overall 5-year survival rate was 48,4%, with no significant diference with respect to the extension of the mediastinal lymphadenectomy. However there was a significant diference in disease-free survival rate in favor of patientes who underwent extended mediastinal lymphadenectomy (0,01). No residual disease(RO), no regional lymph node involvement(pN0) and number of positive lymph node less than 4 were identified as good prognostic factors. CONCLUSION: The esophagogastrectomy with two-field lymphadenectomy had a positive impact in 5-year survival rate in patients with thoracic esophageal carcinoma particularly in ECIII patients. Extended mediastinal lymphadenectomy improved the disease-free survival.

OBJETIVO: O melanoma maligno é a causa mais comum de doença metastática envolvendo o trato gastrointestinal, e o intestino delgado o sítio mais freqüentemente envolvido. Este estudo foi realizado com a finalidade de avaliar o quadro clínico, tratamento, evolução e relatar a experiência com o tratamento cirúrgico do melanoma metastático para intestino delgado. MÉTODO: Foram revisados 11 casos operados no período setembro/1987 a setembro/2000, e estudados os dados referentes ao sexo, idade, localização e estadiamento do tumor primário, tempo e manifestação clínica da metástase intestinal. Também foram avaliados o tipo de cirurgia realizada, a ocorrência de complicações e necessidade de reoperações,a presença de outros sítios metastáticos e sobrevida. RESULTADOS: A média de idade dos pacientes foi de 43,3 anos, sendo 54,5% do sexo masculino. Os membros inferiores foram o sítio primário mais freqüente (54,5%), e em 18,2% dos casos a metástase intestinal foi a primeira manifestação da doença. Dor abdominal (72,7%), obstrução intestinal (36,3%) e massa abdominal (27,2%) foram os sintomas mais comuns. Enterectomia com enteroanastomose foi realizada em 72,7% dos pacientes, em caráter emergencial em mais de 50% dos casos. O tempo de sobrevida variou de 6 dias a 90 meses, e a mortalidade foi de 72,7%. CONCLUSÕES: As metástases intestinais devem ser consideradas em qualquer paciente que apresente sintomas gastrointestinais e uma história prévia de lesão melanocítica de pele, e o tratamento cirúrgico, apesar do caráter paliativo, pode ocasionalmente resultar em sobrevida longa. BACKGROUND: Malignant melanoma is the most common metastatic tumor involving the gastrointestinal tract, the small bowel being the localization most frequently involved. The aim of the present study is to evaluate the clinical presentation, treatment, evolution, and relate our experience with the surgical treatment of metastatic melanoma of the small bowel. METHODS: We reviewed 11 patients treated between September 1987 and September 2000. Patients' sex and age, anatomical site and staging of the primary tumor, time and clinical manifestation of the intestinal metastasis were noted. Type of surgery, occurrence of complications and necessity of reoperation, presence of others metastatic sites and survival were also studied. RESULTS: Mean age of the patients was 43,3 years, and 54,5% were male. The lower extremities were the most frequent primary site involved (54,5%), and in 18,2% of the cases intestinal metastasis were the first manifestation of the disease. The most common symptoms were abdominal pain (72,7%), intestinal obstruction (36,3%) and abdominal mass (27,2%). Small bowel resection with entero-enteric anastomosis were done in 72,7% of patients, more than 50% of the cases in emergencial situation. Survival ranged between six days and 90 months, and the mortality was 72,7%. CONCLUSIONS: Intestinal metastasis must be considered in any patient with gastrointestinal symptoms and previous history of melanoma, and the surgical treatment, despite of palliative intent, occasionally can provide long-term survival.

Os autores comparam um modelo convencional de suporte para pontos totais de segurança da parede abdominal com um novo modelo desenvolvido pelo Instituto de Bioengenharia Erasto Gaertner (IBEG) - o modelo MK, avaliando sua efetividade, ocorrência de complicações, aspecto estético, dor na cicatriz cirúrgica e viabilidade econômica. Foram estudados 66 pacientes submetidos a cirurgia abdominal em dois hospitais de Curitiba (Hospital Erasto Gaertner e Hospital de Clínicas da Universidade Federal do Paraná), no período de maio a julho de 1996. Os pacientes foram divididos em dois grupos: no primeiro grupo foi utilizado o modelo MK, enquanto no segundo utilizou-se o modelo convencional. O modelo MK demonstrou menor índice de complicações, entre as quais: hematoma (p=0,01), coleção sero-hemática (p=0,01), abscesso subcutâneo (p=0,01) e úlcera decorrente dos pontos totais (p=0,02). No que diz respeito à dor, o modelo MK foi mais bem tolerado pelos pacientes, com diferença estatisticamente significativa (p=0,004). O resultado estético e a ocorrência de deiscência, evisceração, hérnia incisional e infecção não mostraram diferença significativa entre os dois grupos. O modelo MK mostrou ser efetivo como suporte para pontos totais de segurança, com uma menor incidência de complicações e menor índice de dor local. The authors compare a conventional model of external splint for retention suture for closure of the abdominal wall to a new model, developed by Bioengineering Institute of Erasto Gaertner Hospital (Instituto de Bioengenharia do Hospital Erasto Gaertner/ IBEG) - the MK model, evaluating its effectiveness, occurrence of complications, esthetic aspect, pain in surgical wound e economic viability. Between May and July 1996, 66 patients undergoing to abdominal surgery in two hospitals of Curitiba were randomly allocated to model MK or conventional model. MK model had shown a significant lower incidence of complications as: wound hematoma (p=0,01), serous formation (0,01), subcutaneous abscess (p=0,01) and ulceration resulting from retention suture (p=0,02). Concerning wound pain, model MK was better tolerated by the patients, with statistically significant difference (p=0,004). Esthetic result and the occurrence of dehiscence, evisceration, incisional hernia and infection had shown no significant difference between the two groups. MK model had shown advantages as an external splint for retention suture, when compared with the conventional model, with a lower incidence of complications and local pain.

MÉTODOS: estudo com abordagem quantitativa. Os dados foram coletados através de um questionário, aplicado via internet, contendo perguntas fechadas de escolha múltipla, referentes a acidentes com material biológico. A amostra obtida foi 100 estudantes. RESULTADOS: trinta e dois se acidentaram com materiais biológicos. As atividades de maior risco foram anestesia local (39,47%), sutura (18,42%) e recapeamento de agulha (15,79%). As principais vias de exposição ao material biológico foram contato com olho ou mucosa, com 34%, através de seringa com agulha com 45%. Após a contaminação, apenas 52% notificaram o acidente ao setor responsável. CONCLUSÃO: as principais causas de acidente encontradas e vias de exposição podem ser atribuídas a diversos fatores, como falta de treinamento e ao não uso de equipamentos de proteção individual. Ações preventivas e educativas são de extrema importância para diminuir a incidência dos acidentes com materiais biológicos e melhorar a conduta pós-exposição. É preciso entender as principais causas atribuídas e situações relacionadas a fim de implantar medidas gerais e eficazes. OBJECTIVE: To evaluate the accidents with biological material among medical students interning in a trauma emergency room and identify key related situations, attributed causes and prevention. METHODS: we conducted a study with a quantitative approach. Data were collected through a questionnaire applied via internet, with closed, multiple-choice questions regarding accidents with biological material. The sample comprised 100 students. RESULTS: thirty-two had accidents with biological material. Higher-risk activities were local anesthesia (39.47%), suture (18.42%) and needle recapping (15.79%). The main routes of exposure to biological material were the eyes or mucosa, with 34%, and syringe needle puncture, with 45%. After contamination, only 52% reported the accident to the responsible department. CONCLUSION: The main causes of accidents and routes of exposure found may be attributed to several factors, such as lack of training and failure to use personal protective equipment. Educational and preventive actions are extremely important to reduce the incidence of accidents with biological materials and improve the conduct of post-exposure. It is important to understand the main causes attributed and situations related, so as general and effective measures can be applied.

OBJECTIVE: to describe a new model of training in microsurgery with pig spleen after splenectomy performed by undergraduate students of the Discipline of Operative Technique of the UFPR Medical School. METHODS: after the completion of splenectomy we performed dissection of the vascular pedicle, distal and proximal to the ligation performed for removal of the spleen. After complete dissection of the splenic artery and vein with microscope, clamps were placed and the vessels were cut. We then made the anastomosis of the vessels with 9.0 nylon. RESULT: the microsurgical training with a well-defined routine, qualified supervision and using low cost experimental materials proved to be effective in the practice of initial microvascular surgery. CONCLUSION: the use of pig spleen, which would be discarded after splenectomy, is an excellent model for microsurgical training, since besides having the consistency and sensitivity of a real model, it saves the sacrifice of a new animal model in the initial learning phase of this technique. OBJETIVO: descrever um novo modelo de treinamento em microcirurgia com baço de suínos após esplenectomia realizada pelos alunos de graduação da disciplina de técnica operatória do curso de medicina da UFPR. MÉTODOS: após a realização da esplenectomia realizamos dissecção do pedículo vascular distal e proximal a ligadura realizada para a retirada do baço. Após a dissecção completa da artéria e veia esplênica ,com microscópio, são colocados os clampes e o vaso é seccionado. É então realizada a anastomose dos vasos com mononylon 9,0. RESULTADO: o treinamento microcirúrgico, com uma rotina bem definida, supervisão qualificada e utilizando materiais experimentais de baixo custo, mostrou-se efetivo na prática de cirurgia microvascular inicial. CONCLUSÃO: a utilização do baço suíno, que seria desprezado após esplenectomia, é um excelente modelo para treinamento microcirúrgico, pois além de ter a consistência e delicadeza de um modelo real poupa o sacrifício de um novo modelo animal, na fase inicial de aprendizado desta técnica.

There are currently various concepts related to quality, which have been implemented by many hospitals and other healthcare institutions. The search for continuous improvement, the implementation of a quality culture and hospital accreditation have also been common, in these institutions. However, the history of hospital audits and accreditation is complex and full of dynamic concepts. The American College of Surgeons was pioneer in publishing, more than a century ago, the first document pertaining quality standards. After that, various programs and concepts have been developed and remodeled by distinct entities. In this article, we briefly review the history of quality in the world and Brazil. We also discuss related concepts regarding its assessment in healthcare. RESUMO Sólidos conceitos de qualidade assistencial são adotados em grandes hospitais e serviços de saúde da atualidade. A busca por melhoria contínua, implementação de cultura de qualidade e obtenção de selos de certificação em qualidade hospitalar é comum em tais instituições. Entretanto, a história da avaliação hospitalar e do processo de certificação é longa e repleta de conceitos dinâmicos. O “American College of Surgeons” foi pioneiro ao publicar há mais de um século o primeiro documento contendo diretrizes sobre padrões de qualidade a serem seguidos. Posteriormente, múltiplos programas e conceitos foram criados e remodelados por distintas entidades. Neste artigo, apresentamos breve revisão da história da qualidade no mundo e no Brasil, além de alguns conceitos relacionados à avaliação da mesma em saúde.

RESUMO Objetivo: avaliar a percepção dos cirurgiões, membros do Colégio Brasileiro de Cirurgiões (CBC), sobre temas de segurança e qualidade em cirurgia, com base em Projetos do Ministério da Saúde (MS), do CBC, da Organização Mundial de Saúde (OMS) e do Colégio Americano de Cirurgiões (ACS). Métodos: questionário com base nas iniciativas da OMS, do CBC e do ACS foi enviado pelo Survey Monkey a todos os sócios, ativos e não ativos, do CBC em março de 2018. Resultados: responderam ao questionário 171 profissionais dentre os 7.100 sócios. Desses, a maioria (63,2%) declarou praticar Cirurgia Geral, 88,9% indicaram conhecer o Projeto Cirurgia Segura do MS, 73,1%, o Manual do CBC e 14,6%, o Strong for Surgery do ACS. Entre os que conhecem o Projeto do MS, 73,1% disseram usá-lo como rotina e, entre os que conhecem o Manual do CBC, 46,2% usam-no. A maior parte dos cirurgiões (81,3%) indicou que já vivenciou falha cirúrgica grave, sendo aquelas relacionadas com material cirúrgico (49,7%) e presença de corpos estranhos (8,2%), isoladamente, as mais comuns. Houve opiniões distintas sobre a responsabilidade de conferência do checklist. Conclusão: a importância da segurança e qualidade em cirurgia é conhecida pelos cirurgiões, mas a prática é variada. Eventos adversos graves foram vivenciados por muitos cirurgiões, principalmente relacionados com material cirúrgico e corpos estranhos. O conceito de interdisciplinaridade parece não ser prática comum. Os dados indicam a necessidade de desenvolver projetos de educação e a obrigatoriedade de auditorias.

RESUMO Objetivo: avaliar a viabilidade de abreviação do jejum em cirurgias colorretais oncológicas, bem como, o impacto no desfecho cirúrgico dos pacientes. Métodos: estudo prospectivo comparativo randomizado com pacientes submetidos à cirurgias eletivas colorretais, por câncer, no período de maio a setembro de 2017. Os pacientes foram randomizados eletronicamente em dois grupos de acordo com o jejum pré-operatório a ser adotado: convencional ou abreviado. Resultados: dos 33 pacientes incluídos, 15 seguiram o protocolo de jejum abreviado e 18 de jejum convencional. Ambos os grupos apresentaram perfis comparáveis. Nenhum paciente foi submetido a preparo mecânico do cólon. Em 69,7% dos casos, a cirurgia envolveu dissecção baixa do reto. Os procedimentos foram equivalentes em relação às variáveis intraoperatórias e complicações graves. O tempo para atingir realimentação plena foi menor para o jejum abreviado (10 versus 16 dias, p=0,001), assim como, o tempo de internação hospitalar (2 versus 4 dias, p=0,009). Os custos hospitalares foram menores no jejum abreviado (331 versus 682 reais, p
