Preoperative evaluation of gastric cancer and risk factors for postoperative complications / 中华胃肠外科杂志

Surgical resection plays pivotal role in the treatment of gastric cancer. Adequate preoperative evaluation, precise intraoperative maneuver and delicate postoperative management lay the foundation for successful gastrectomy. The aim of preoperative evaluation is to stage tumor and identify potential risk factors (including preoperative factors like age, ASA status, body mass index, comorbidity, hypoalbuminemia, and intraoperative factors like blood loss and combined resection) which could lead to postoperative complication. With the management of prehabilitation, adequate medical decision could be made and patient's fast recovery could be ensured. With the rapid adoption of ERAS concept, there is increasing attention to prehabilitation which focus on optimization of cardio-pulmonary capacity and muscular-skeletal capacity. Despite of the efficacy of prehabilitation demonstrated by randomized controlled trials, consensus has yet to be reached on the following items: specific intervention, optimal measurement, candidate population and optimal timing for intervention. Balancing the efficiency and safety, preoperative evaluation could be put into clinical practice smoothly.

Changing paradigms in preoperative fasting: results of a joint effort in pediatric surgery / Mudando paradigmas em jejum pré-operatório: resultados de um mutirão em cirurgia pediátrica

ABSTRACT Background: Current researches associate long fasting periods to several adverse consequences. The fasting abbreviation to 2 h to clear liquids associated with the use of drinks containing carbohydrates attenuates endocrinometabolic response to surgical trauma, but often is observed children advised to not intake food from 00:00 h till the scheduled surgical time, regardless of what it is. Aim: To evaluate the safety of a protocol of preoperative fasting abbreviation with a beverage containing carbohydrates, and early postoperative feeding in children underwent elective small/mid-size surgical procedures during a national task-force on pediatric surgery. Methods: Thirty-six patients were prospectively included, and for several reasons five were excluded. All 31 who remained in the study received a nutritional supplement containing 150 ml of water plus 12.5% maltodextrin 2 h before the procedure. Data of the pre-operative fasting time, anesthetic complications and time of postoperative refeeding, were collected. Results: Twenty-three (74.2%) were males, the median age was 5 y, and the median weight was 20 kg. The median time of pre-operative fasting was 145 min and the time of post-operative refeeding was 135 min. There were no adverse effects on the anesthetic procedures or during surgery. Post-operatively, two children (6.5%) vomited. Conclusion: The abbreviation of pre-operative fasting to 2 h with beverage containing carbohydrate in pediatric surgery is safe. Early refeeding in elective small/mid-size procedures can be prescribed.

RESUMO Racional: Trabalhos atuais associam longos períodos de jejum com diversas consequências adversas. A abreviação do jejum de 2 h para líquidos claros associado ao uso de bebidas contendo carboidratos atenua resposta endocrinometabólica ao trauma, porém frequentemente as crianças são orientadas a não ingerir alimentos a partir das 00:00 h do dia anterior à operação, independente do horário do procedimento cirúrgico. Objetivo: Avaliar a segurança de um protocolo de abreviação do jejum pré-operatório, com o uso de bebida contendo carboidratos, e realimentação precoce. Métodos: Foram avaliados prospectivamente 36 crianças submetidas a procedimentos cirúrgicos eletivos de pequeno e médio porte. Cinco foram posteriormente excluídos do estudo. Todos os 31 remanescentes receberam suplemento nutricional com maltodextrina 12,5% em 150 ml de água aproximadamente 2 h antes do procedimento. Foram coletados dados do tempo de jejum pré-operatório, complicações anestésicas e tempo de realimentação. Resultados: Vinte e três (74,2%) eram do gênero masculino, com idade mediana de cinco anos e peso mediano de 20 kg. O tempo mediano de jejum pré-operatório foi de 145 min e o tempo mediano para realimentação foi de 135 min. Não houve eventos adversos durante a anestesia ou operação. No período pós-operatório, duas (6,5%) crianças vomitaram. Conclusão: A abreviação de jejum pré-operatório para 2 h com uso de bebida contendo carboidratos, em operações eletivas de crianças, é seguro e não está associado ao maior risco de broncoaspiração pulmonar. Realimentação precoce pode ser prescrita nos procedimentos cirúrgicos analisados.

Does Polyethylene Glycol (PEG) Plus Ascorbic Acid Induce More Mucosal Injuries than Split-Dose 4-L PEG during Bowel Preparation?

BACKGROUND/AIMS: The aims of this study were to compare the bowel-cleansing efficacy, patient affinity for the preparation solution, and mucosal injury between a split dose of poly-ethylene glycol (SD-PEG) and low-volume PEG plus ascorbic acid (LV-PEG+Asc) in outpatient scheduled colonoscopies. METHODS: Of the 319 patients, 160 were enrolled for SD-PEG, and 159 for LV-PEG+Asc. The bowel-cleansing efficacy was rated according to the Ottawa bowel preparation scale. Patient affinity for the preparation solution was assessed using a questionnaire. All mucosal injuries observed during colonoscopy were biopsied and histopathologically reviewed. RESULTS: There was no significant difference in bowel cleansing between the groups. The LV-PEG+Asc group reported better patient acceptance and preference. There were no significant differences in the incidence or characteristics of the mucosal injuries between the two groups. CONCLUSIONS: Compared with SD-PEG, LV-PEG+Asc exhibited equivalent bowel-cleansing efficacy and resulted in improved patient acceptance and preference. There was no significant difference in mucosal injury between SD-PEG and LV-PEG+Asc. Thus, the LV-PEG+Asc preparation could be used more effectively and easily for routine colonoscopies without risking significant mucosal injury.

Oral surgery in patients under antithrombotic therapy / Cirugía bucal en pacientes con terapia antitrombótica: revisión narrativa

Population aging and the increasing rates of cardiovascular diseases have raised the number of patients receiving antithrombotic therapy in elective or emergency dental care, including surgical procedures. The aim of this article is to review the evidence and clinical guidelines for management of patients on antithrombotic therapy published in the past five years. TheAmerican Antithrombotic Therapy Guideline - 2012 - generally recommends not to suspend antiplatelet or anticoagulant treatment in dental procedures since they are considered to have low bleeding risk and easy resolution. In the dental field, there is ample published evidence regarding oral surgical procedure management, especially by maxillofacial surgeons, showing a low number of complications associated with extractions or other minor oral surgical procedures without suspending antithrombotic drugs and only taking some minimum safeguards, such as healing by first intention or the use of some local hemostatic agents. In general, patients under chronic antithrombotic therapy should keep their medication when undergoing low and medium complexity dental procedures, since complications are minor and easy to handle. Due to interactions between them, particular care should be taken with patients using more than one drug...

El envejecimiento poblacional y el aumento patologías cardiovasculares ha aumentado la cantidad de pacientes bajo terapia antitrombótica que reciben atención dental electiva o de urgencia, incluidos los procedimientos quirúrgico. El objetivo de este artículo es revisar la evidencia y las guías clínicas publicadas en los últimos 5 anos respecto al manejo odontológico de pacientesbajo terapia antitrombótica. La guía clínica americana de terapia antitrombótica del ano 2012 recomienda en general no suspender la terapia antiplaquetaria ni anticoagulante, en los procedimientos dentales ya que son considerados como de bajo riesgo de sangrado y de fácil resolución. En el área odontológica existe amplia evidencia publicada respecto al manejo de procedimientos quirúrgicos bucales, especialmente por cirujanos maxilofaciales, que ha demostrado la baja cantidad de complicaciones asociadas a exodoncias u otras cirugías menores de la cavidad bucal; sin la necesidad de suspender los medicamentos antitrombóticos y tomando algunos resguardos mínimos como la cicatrización por primera intención o el uso de algunos agentes hemostáticos locales. En términos generales los pacientes bajo terapia antitrombótica crónica deben mantener sus medicamentos cuando son sometidos a procedimientos dentales de baja y mediana complejidad, ya que las complicaciones son menores y de sencillo manejo. Se debe poner especialatención en pacientes con más de un medicamento, por las interacciones entre ellos...

A Comparison of Preoperative Biliary Drainage Methods for Perihilar Cholangiocarcinoma: Endoscopic versus Percutaneous Transhepatic Biliary Drainage

BACKGROUND/AIMS: Controversy remains over the optimal approach to preoperative biliary drainage in patients with resectable perihilar cholangiocarcinoma. We compared the clinical outcomes of endoscopic biliary drainage (EBD) with those of percutaneous transhepatic biliary drainage (PTBD) in patients undergoing preoperative biliary drainage for perihilar cholangiocarcinoma. METHODS: A total of 106 consecutive patients who underwent biliary drainage before surgical treatment were divided into two groups: the PTBD group (n=62) and the EBD group (n=44). RESULTS: Successful drainage on the first attempt was achieved in 36 of 62 patients (58.1%) with PTBD, and in 25 of 44 patients (56.8%) with EBD. There were no significant differences in predrainage patient demographics and decompression periods between the two groups. Procedure-related complications, especially cholangitis and pancreatitis, were significantly more frequent in the EBD group than the PTBD group (PTBD vs EBD: 22.6% vs 54.5%, p<0.001). Two patients (3.8%) in the PTBD group experienced catheter tract implantation metastasis after curative resection during the follow-up period. CONCLUSIONS: EBD was associated with a higher risk of procedure-related complications than PTBD. These complications were managed properly without severe morbidity; however, in the PTBD group, there were two cases of cancer dissemination along the catheter tract.

The Impact of Mechanical Bowel Preparation in Elective Colorectal Surgery: A Propensity Score Matching Analysis

PURPOSE: To evaluate the influence of preoperative mechanical bowel preparation (MBP) based on the occurrence of anastomosis leakage, surgical site infection (SSI), and severity of surgical complication when performing elective colorectal surgery. MATERIALS AND METHODS: MBP and non-MBP patients were matched using propensity score. The outcomes were evaluated according to tumor location such as right- (n=84) and left-sided colon (n=50) and rectum (n=100). In the non-MBP group, patients with right-sided colon cancer did not receive any preparation, and patients with both left-sided colon and rectal cancers were given one rectal enema before surgery. RESULTS: In the right-sided colon surgery, there was no anastomosis leakage. SSI occurred in 2 (4.8%) and 4 patients (9.5%) in the non-MBP and MBP groups, respectively. In the left-sided colon cancer surgery, there was one anastomosis leakage (4.0%) in each group. SSI occurred in none in the rectal enema group and in 2 patients (8.0%) in the MBP group. In the rectal cancer surgery, there were 5 anastomosis leakages (10.0%) in the rectal enema group and 2 (4.0%) in the MBP group. SSI occurred in 3 patients (6.0%) in each groups. Severe surgical complications (Grade III, IV, or V) based on Dindo-Clavien classification, occurred in 7 patients (14.0%) in the rectal enema group and 1 patient (2.0%) in the MBP group (p=0.03). CONCLUSION: Right- and left-sided colon cancer surgery can be performed safely without MBP. In rectal cancer surgery, rectal enema only before surgery seems to be dangerous because of the higher rate of severe postoperative complications.

Menor tempo de jejum pré-operatório e alimentação precoce no pós-operatório são seguros? / Lesser time of preoperative fasting and early postoperative feeding are safe?

INTRODUÇÃO: O jejum noturno praticado antes de operações eletivas foi instituído para prevenir complicações pulmonares, vômitos, regurgitação e aspiração do conteúdo gástrico. No ano de 2005 foi desenvolvido o projeto de Aceleração da Recuperação Total Pós-operatória, denominado ACERTO. O projeto é composto por uma equipe multidisciplinar que visa à recuperação do paciente cirúrgico administrando de duas a seis horas antes da operação uma bebida rica em carboidratos (12,5% de dextrinomaltose). A equipe multidisciplinar é composta por anestesistas, cirurgiões, nutricionistas, enfermeiros e fisioterapeutas. OBJETIVO: Frente aos novos métodos de controle no pré-operatório verificar a qual a necessidade de jejum antes de procedimentos cirúrgicos. MÉTODOS: Revisão sobre jejum pré-operatório realizada nos meses de setembro e outubro de 2011, nos sites de busca Scielo e PubMed. Foram selecionados 24 artigos. CONCLUSÃO: Reduzir o tempo de jejum pré-operatório com solução rica em carboidratos até duas horas antes da operação, tal como alimentação precoce no pós-operatório, trazem inúmeros benefícios ao paciente. O projeto ACERTO tem demonstrado bons resultados e estas novas condutas devem ser encorajadas, diminuindo assim o tempo de recuperação do paciente cirúrgico.

INTRODUCTION: Fasting in the night before elective surgery has been established to prevent pulmonary complications, vomiting, regurgitation and aspiration of gastric contents. The year of 2005 was developed the project ACERTO. It consists in a multidisciplinary team that aims to recover the surgical patient by administering two our six hours before surgery, a carbohydrate-rich beverage (12.5% dextrinomaltose). The multidisciplinary team consists of anesthesiologists, surgeons, nutritionists, nurses and physiotherapists. METHODS: Literature review of preoperative fasting conducted during September and October of 2011 in Scielo and PubMed. CONCLUSION: Reducing the time of preoperative fasting with high carbohydrate solution until two hours before the operation as early feeding postoperatively, bring numerous benefits to the patient. The ACERTO project has shown good results and these new behaviors should be encouraged, thereby reducing the recovery time of the surgical patient.

Utilidad de la preparación mecánica anterógrada en cirugía colorrectal electiva: resultados de una serie prospectiva y aleatoria / Usefulness of anterograde mechanical colon cleansing in colorectal surgery

Background: Anterograde mechanical colon cleansing is routinely done before colorectal surgery. However there is no firm evidence about its usefulness. Aim: To assess the usefulness of anterograde mechanical colon cleansing in colon surgery. Patients and Methods: Participants requiring elective colorectal surgery were randomized to receive anterograde mechanical bowel cleansing with two doses of oral sodium phosphate (Oral fleet) or a liquid diet 24 hours prior to surgery, after signing an informed consent. Both groups received antimicrobial prophylaxis. Problems associated with bowel cleansing, subjective assessment of bowel preparation by the surgeon and postoperative complications were recorded. Results: One hundred twenty two participants were studied (73 females). Fifty three percent of patients had concomitant diseases such as hypertension and diabetes mellitus. Sixty patients were subjected to anterograde bowel cleansing and 62 were ascribed to the liquid diet group. Surgeons evaluated colon cleansing as good in 49 and 37 patients with and without anterograde mechanical cleansing, respectively and as regular in 8 and 23 patients, respectively (X2 = 9.1 p = 0.01). Tolerance to cleansing was evaluated as good, fair and poor by 50, 30 and 20 percent of patients, respectively. One patient had a bowel obstruction associated with the use of sodium phosphate. Postoperative complications occurred in 14 and 23 patients subjected or not to cleansing, respectively (p = 0.06). Septic complications occurred in 11 and 3 cases with and without colon cleansing, respectively (p < 0.01). Conclusions: Anterograde mechanical colon cleansing was associated with a higher incidence of septic complications in this series of patients.

Introducción: El uso de la preparación mecánica anterógrada (PMA) es una práctica rutinaria en cirugía colorrectal pero con escasas bases en la evidencia científica. Objetivo: Determinar la utilidad de la PMA en una serie prospectiva y aleatoria de cirugía colorrectal electiva. Resultados: La serie corresponde a 122 pacientes, 60 de los cuales recibe PMA. Los datos epidemiológicos muestran que los grupos son comparables. En esta serie se encuentra un riesgo de morbilidad global aumentado al doble en los pacientes que reciben PMA, así como un riesgo de infección superficial del sitio quirúrgico seis veces mayor. No se encuentran diferencias en las infecciones profundas, dehiscencia de anastomosis ni en las reintervenciones. Las complicaciones asociadas a la PMA se presentaron sólo en un caso, 10 que no alcanza significación estadística. Conclusiones: De acuerdo a nuestros resultados, no se justifica la utilización rutinaria de PMA.

Segurança da ablação de fibrilação atrial com RNI terapêutico: comparação com a transição com heparina de baixo peso / Safety of ablation for atrial fibrillation with therapeutic INR: comparison with transition to low-molecular-weight heparin

FUNDAMENTO: O manejo ideal da anticoagulação oral (ACO) no período pré- e pós-ablação de fibrilação atrial (FA) ainda é motivo de controvérsia. OBJETIVO: Comparar duas estratégias de anticoagulação: suspensão da warfarina com a utilização de heparina de baixo peso molecular (HBPM) e a realização da ablação sem a suspensão da warfarina, mantendo o RNI terapêutico (entre 2,0 e 3,0). MÉTODOS: 140 pacientes (pt) portadores de FA persistente/ permanente submetidos à ablação por cateter de FA foram divididos em dois grupos: no grupo I (70 pt), a warfarina foi suspensa cinco dias antes do procedimento e utilizada terapia de transição com HBPM (enoxaparina 1 mg/kg 2x/dia pré-ablação e 0,5 mg/kg 2x/dia após o procedimento); no grupo II (70 pt), a warfarina não foi suspensa e o procedimento foi realizado com RNI terapêutico. Ambos os grupos receberam heparina intravenosa (TCA > 350 seg) durante o procedimento. RESULTADOS: No Grupo I, observou-se complicação hemorrágica maior (1,4 por cento) e 4 pt (5,7 por cento) com complicações hemorrágicas menores. No Grupo II, 2 pt (2,8 por cento) apresentaram complicações hemorrágicas menores e 1 pt apresentou sangramento maior; porém, este ocorreu após uso de HBPM por RNI < 2,0. Não houve complicação tromboembólica ou morte cardiovascular nos dois grupos após 16 ± 8 meses. CONCLUSÃO: A realização de ablação por cateter de FA sem a suspensão de ACO e RNI terapêutico é uma estratégia semelhante em segurança e eficácia quando comparada à tradicional transição com HBPM, evitando um período inicial pós-ablação de anticoagulação potencialmente inadequada.

BACKGROUND: The ideal management of oral anticoagulation (OAC) before and after catheter ablation for atrial fibrillation (AF) is still controversial. OBJECTIVE: To compare two anticoagulation strategies for catheter ablation for AF: warfarin withholding and use of low-molecular-weight heparin (LMWH); and maintenance of warfarin and therapeutic INR (between 2.0 and 3.0). METHODS: 140 patients (pt) with persistent/permanent AF undergoing catheter ablation for AF were divided into two groups: Group I (70 pt), in which warfarin was withheld five days prior to the procedure and transition to LMWH was used (enoxaparin: 1 mg/kg 2x/day before ablation, and 0.5 mg/kg 2x/day after ablation); Group II (70 pt), in which warfarin was not withheld and the procedure was performed with therapeutic INR. Both groups received intravenous heparin (ACT > 350 seconds) during ablation. RESULTS: In Group I, one pt (1.4 percent) had a major hemorrhagic complication and four pts (5.7 percent) had minor hemorrhagic complications. In Group II, two pts (2.8 percent) had minor hemorrhagic complications and one pt had a major bleeding, which occurred after using LMWH due to INR < 2.0. None of the groups had thromboembolic complications or cardiovascular death over a period of 16 ± 8 months. CONCLUSION: Catheter ablation for AF without withholding OAC and with therapeutic INR is a strategy that has similar safety and efficacy when compared with the traditional transition to LMWH, avoiding the potentially inadequate anticoagulation of the initial post-ablation period.

Influência da força muscular respiratória na evolução de pacientes com insuficiência cardíaca após cirurgia cardíaca / Influence of respiratory muscle strength in evolution of patients with heart failure after cardiac surgery

OBJETIVOS: Verificar a influência da força muscular respiratória pré-operatória na incidência de complicações pulmonares no pós-operatório de cirurgia cardíaca em pacientes com insuficiência cardíaca. MÉTODOS: De março de 2009 a setembro de 2010, 40 pacientes internados no serviço de cardiologia da Fundação de Beneficência Hospital de Cirurgia foram distribuídos em dois grupos, de acordo com os valores da pressão inspiratória máxima avaliada por meio da manovacuometria: Grupo A (n=21), composto de pacientes que apresentaram força muscular respiratória normal; e grupo B (n=19), pacientes com redução da força. Após a avaliação pré operatória, todos foram submetidos ao procedimento cirúrgico e acompanhados até o momento da alta hospitalar pelo mesmo pesquisador, que anotava na ficha de coleta de dados sua evolução, especialmente quanto à presença de complicações pulmonares no pós-operatório, que foi dividida em geral e específica. RESULTADOS: Dezenove por cento dos pacientes do grupo A e 31,6% dos pacientes do grupo B apresentaram complicações pulmonares gerais, sendo esta diferença não significativa estatisticamente (P=0,29). Quanto à presença de complicações específicas, o grupo A teve 14,3% e o grupo B 10,5% (P= 0,55). Também não houve diferença quanto aos dias de internação em UTI e total (UTI + enfermaria) entre os grupos. CONCLUSÃO: Nesse trabalho, a disfunção muscular respiratória no pré-operatório de cirurgia cardíaca não foi considerada um fator de risco para desenvolvimento de complicações pulmonares no pós-operatório.

OBJECTIVE: To investigate the influence of preoperative respiratory muscle strength in postoperative pulmonary complications in patients with heart failure undergoing cardiac surgery. METHODS: From March 2009 to September 2010, 40 patients admitted to the cardiology service of the Fundação de Beneficência Hospital de Cirurgia were divided into two groups according to the values of maximal inspiratory pressure measured by manometer: Group A (n = 21), composed of patients with normal respiratory muscle strength, and Group B (n = 19), patients with reduced strength. After pre-operative evaluation, all patients underwent the surgical procedure and followed until hospital discharge by the same researcher, who recorded on data collection especially its evolution for the presence of pulmonary complications after surgery, which was divided general and specific. RESULTS: 19% of patients in group A and 31.6% of patients in group B had pulmonary complications overall, this difference was not statistically significant (P = 0.29). Regarding the presence of specific complications, group A was 14.3% and 10.5% group B (P = 0.55). There was also no difference in the days of ICU stay and total (ICU + ward) between groups. CONCLUSION: In this study, preoperative respiratory muscle dysfunction does not seem to influence the evolution of heart failure patients for the presence of pulmonary complications after cardiac surgery.

O uso de inibidores da enzima conversora de angiotensina e sua relação com eventos no pós-operatório de cirurgia de revascularização miocárdica / The use of inhibitors of angiotensin-converting enzyme and its relation to events in the postoperative period of CABG

FUNDAMENTO: Os inibidores da enzima conversora de angiotensina (IECA) reduzem o risco de óbito, infarto agudo do miocárdio (IAM) e acidente vascular encefálico (AVE) em portadores de doença coronariana. No entanto, não há consenso quanto à sua indicação em pacientes que serão submetidos à cirurgia de revascularização miocárdica (CRM). OBJETIVO: Avaliar a relação entre uso pré-operatório de IECA e eventos clínicos após realização da CRM. MÉTODOS: Estudo de coorte retrospectivo. Foram incluídos dados de 3.139 pacientes consecutivos submetidos à CRM isolada em hospital terciário brasileiro, entre janeiro de 1996 e dezembro de 2009. O seguimento dos pacientes foi realizado até a alta hospitalar ou óbito. Desfechos clínicos no pós-operatório foram analisados entre os usuários e os não-usuários de IECA no pré-operatório. RESULTADOS: Cinquenta e dois por cento (1.635) dos pacientes receberam IECA no pré-operatório. O uso de IECA foi preditor independente da necessidade de suporte inotrópico (RC 1,24, IC 1,01-1,47; P=0,01), de insuficiência renal aguda (IRA, RC 1,23, IC 1,01-1,73; P=0,04) e de evolução para fibrilação atrial (FA, RC 1,32, IC 1,02-1,7; P=0,03) no pós-operatório. A mortalidade entre os pacientes que receberam ou não IECA no pré-operatório foi semelhante (10,3 vs. 9,4%, P=0,436), bem como a incidência de IAM e AVE (15,6 vs. 15,0%, P=0,694 e 3,4 vs. 3,5%, P=0,963, respectivamente). CONCLUSÃO: O uso pré-operatório de IECA foi associado a maior necessidade de suporte inotrópico e maior incidência de IRA e FA no pós-operatório, não estando associado ao aumento das taxas de IAM, AVE ou óbito.

BACKGROUND: Angiotensin-converting enzyme (ACE) inhibitors reduce the chance of death, myocardial infarction (MI) and cerebrovascular accident (CVA) in patients with coronary disease. However there is no consensus as to its indication in patients undergoing coronary artery bypass grafting (CABG). OBJECTIVE: To assess the relationship between preoperative use of ACE inhibitors and clinical outcomes after CABG. METHODS: Retrospective cohort study. We included data from 3,139 consecutive patients undergoing isolated CABG in Brazilian tertiary care hospital between January 1996 and December 2009. Follow-up was until discharge or death. Clinical outcomes after surgery were analyzed between users and nonusers of ACE inhibitors preoperatively. RESULTS: Fifty-two percent (n=1,635) of patients received ACE inhibitors preoperatively. The use of ACE inhibitors was an independent predictor of need for inotropic support (OR 1.24, 95% CI 1.01 to 1.47, P = 0.01), acute renal failure (OR 1.23, 95% CI 1.01 to 1.73, P = 0.04) and progression to atrial fibrillation (OR 1.32, 95% CI 1.02 to 1.7, P = 0.03) postoperatively. The mortality rate among patients receiving or not preoperative ACE inhibitors was similar (10.3% vs. 9.4%, P = 0.436), as well as the incidence of myocardial infarction and stroke (15.6% vs. 15.0%, P = 0.694 and 3.4% vs. 3.5%, P = 0.963, respectively). CONCLUSION: The use of preoperative ACE inhibitors was associated with increased need for inotropic support and higher incidence of acute renal failure and postoperative atrial fibrillation, not associated with increased rates of myocardial infarction, stroke or death.

Preoperative nodal staging of non-small cell lung cancer using 99mTc-sestamibi spect/ct imaging

OBJECTIVES: The proper nodal staging of non-small cell lung cancer is important for choosing the best treatment modality. Although computed tomography remains the first-line imaging test for the primary staging of lung cancer, its limitations for mediastinum nodal staging are well known. The aim of this study is to evaluate the accuracy of hybrid single-photon emission computed tomography and computed tomography using 99mTc-sestamibi in the nodal staging of patients with non-small cell lung cancer and to identify potential candidates for surgical treatment. METHODS: Prospective data were collected for 41 patients from December 2006 to February 2009. The patients underwent chest computed tomography and single-photon emission computed tomography/computed tomography examinations with 99mTc-sestamibi within a 30-day time period before surgery. Single-photon emission computed tomography/computed tomography was considered positive when there was focal uptake of sestamibi in the mediastinum, and computed tomography scan when there was lymph nodes larger than 10 mm in short axis. The results of single-photon emission computed tomography and computed tomography were correlated with pathology findings after surgery. RESULTS: Single-photon emission computed tomography/computed tomography correctly identified six out of 19 cases involving hilar lymph nodes and one out of seven cases involving nodal metastases in the mediastinum. The sensitivity, specificity, positive predictive value, and negative predictive value for 99mTc-sestamibi single-photon emission computed tomography/computed tomography in the hilum assessment were 31.6 percent, 95.5 percent, 85.7 percent, and 61.8 percent, respectively. The same values for the mediastinum were 14.3 percent, 97.1 percent, 50 percent, and 84.6 percent, respectively. For the hilar and mediastinal lymph nodes, chest tomography showed sensitivity values of 47.4 percent and 57.1 percent, specificity values of 95.5 percent and 91.2 percent, positive predictive values of 90 percent and 57.1 percent and negative predictive values of 67.7 percent and 91.2 percent, respectively. CONCLUSION: Single-photon emission computed tomography/computed tomography with 99mTc-sestamibi showed very low sensitivity and accuracy for the nodal staging of patients with non-small cell lung cancer, despite its high level of specificity. In addition, the performance of single-photon emission computed tomography/computed tomography added no relevant information compared to computed tomography that would justify its use in the routine preoperative staging of non-small cell lung carcinoma.

Efeitos de orientações fisioterapêuticas sobre a ansiedade de pacientes submetidos à cirurgia de revascularização miocárdica / Effects of physiotherapeutic instructions on anxiety of CABG patients

INTRODUÇÃO: A cirurgia de revascularização é uma opção de tratamento para as doenças cardiovasculares, sendo que os indivíduos a esta submetidos podem sofrer quadros de ansiedade pré-operatória. OBJETIVO: O objetivo deste estudo é verificar os efeitos de orientações fisioterapêuticas sobre o nível de ansiedade em pacientes submetidos à cirurgia de revascularização do miocárdio. MÉTODOS: Ensaio clínico randomizado, com amostra composta por 51 indivíduos, sendo 27 do grupo controle e 24 de intervenção, nos quais foram avaliados os níveis de ansiedade (Escala de Beck) e dor (Escala Análogo Visual), nos períodos pré e pós-operatório, sendo que somente o grupo intervenção recebeu orientações sobre os procedimentos cirúrgicos e exercícios ventilatórios. Para análise dos dados foram utilizados os testes de Wilcoxon, Mann-Whitney e Spearman. RESULTADOS: Observaram-se escores de ansiedade mais baixos nos pacientes que receberam a intervenção antes da cirurgia (9,6 ± 7,2 versus 13,4 ± 5,9, P=0,02). No grupo controle, a diferença entre os escores de ansiedade antes e após a cirurgia foi significativa (P=0,003). Os indivíduos do sexo feminino apresentaram-se mais ansiosos no pré-operatório comparados aos do sexo masculino (P=0,058). Verificou-se também relação entre o tempo de permanência no hospital e ansiedade pós-operatória (P=0,05), sendo que os indivíduos mais ansiosos permaneceram internados por maior período de tempo. CONCLUSÃO: Pacientes orientados e instruídos, quanto a exercícios ventilatórios fisioterapêuticos e rotinas hospitalares, tiveram menores níveis de ansiedade no pré-operatório, quando comparados ao grupo controle. Entretanto, no período pós-operatório, ambos os grupos tiveram seus níveis de ansiedade reduzidos, sem diferença significativa entre eles

INTRODUCTION: The coronary artery bypass graft surgery is an option of treatment for cardiovascular diseases, and the patients who underwent such procedure can suffer from preoperative anxiety. OBJECTIVE: The aim of this study is to verify the effects of physiotherapeutic instructions at the anxiety level on patients undergone coronary artery bypass graft surgery. METHODS: Randomized clinical trial, with the sample composed by 51 individuals, 27 on the control group and 24 on the intervention; on which it was assessed the anxiety (Beck Scale for Anxiety) and pain (Visual Analog Scale) levels on the pre- and postoperative period and only the second group received instructions about the surgery procedures and ventilatory exercises. For statistical analysis the Wilcoxon, Mann-Whitney and Spearman tests were used. RESULTS: The lower anxiety levels were observed in patients that received the intervention on the period before surgery (9.6 ± 7.2 versus 13.4 ± 5.9, P=0.02). On the control group, the difference among the anxiety levels before and after the surgery was statistically significant (P= 0.003). The female individuals presented more anxious before the surgery compared to the male ones (P=0.058). It was also verified a relationship between lenght of stay at hospital and postoperative anxiety (P=0.05), where the more anxious individuals remained more time at the hospital. CONCLUSION: Patients oriented and instructed about physiotherapeutic ventilatory exercises and hospital routine, presented their levels of anxiety reduced on the preoperative compared to the control group. However, at the postoperative, both groups presented their anxiety levels reduced without significant difference between them

Degree of risk related to procedures performed in conjunction with surgical myocardial revascularization in octogenarians

INTRODUCTION/OBJECTIVES: We determined the degree of risk produced by the association of other surgical procedures with surgical myocardial revascularization in octogenarian patients and identified the risk factors that best explain hospital mortality. METHODS: This study was an observational analytical historical cohort study involving octogenarians operated on at our institution between January 1, 2000 and January 1, 2005. We stratified the objective population as follows: Group 1 comprised octogenarians revascularized without associated procedures, and Group 2 comprised octogenarians revascularized with associated procedures. Statistical analyses included the t test for independent samples and multiple logistic regression analysis. Significance was accepted with an alpha error of 5 percent. RESULTS: Univariate analyses revealed the following clinical and statistically significant variables: hospital mortality (P=0.002), diabetes mellitus (P=0.017), preoperative endocarditis (P=0.001), cardiogenic shock (P=0.019), use of an intra-aortic balloon pump (P=0.026), preoperative risk score (Parsonnet), P<0.001, procedure associated with revascularization (P<0.001), medium number of affected coronary arteries (P<0.001), use of extracorporeal circulation (P<0.001), time of extracorporeal circulation (P<0.001), number of distal anastomoses (P=0.002), graft type (P<0.001), postoperative breathing support (P<0.001), stroke (P<0.001), infection (P=0.002), creatinine level (P=0.018), and quality of life score (P=0.050). DISCUSSION/CONCLUSIONS: In octogenarian patients, the need for a procedure associated with surgical myocardial revascularization produces an absolute increase in hospital mortality risk of 45 percent. The variables that contributed to hospital mortality were preoperative endocarditis, preoperative cardiogenic shock, the use of extracorporeal circulation, the length of time of extracorporeal circulation, postoperative creatinine level, ...

Evaluación prospectiva de la seguridad y tolerancia de los procedimientos colonoscópicos en pacientes pediátricos / Prospective evaluation of safety and tolerance of colonoscopy in children

Background: Colonoscopy is a well established diagnostic and therapeutic procedure in pediatrics. Aim: To evaluate colon preparation alternatives for colonoscopy or sigmoidoscopy, type of sedation, clinical indications and findings. Patients and methods: Prospective study of 123 children referred for colonoscopy. Demographic data, type of colon preparation, sedation, type of endoscope and endoscopic results were obtained. The following day, a phone interview was carried out inquiring about duration, quality and adverse effects of the sedation and procedure. Results: Seventy one boys (58%) and 52 girls (42%) with a mean age of 6.7±4.4 years, were recruited. The main indication was lower gastrointestinal bleeding (71%). The different colon preparations produced elimination of clear liquid stools in 50%, non transparent liquid in 23%, semi liquid in 22% and solid in 6% of the patients. Most common side effects were abdominal distension (20%) and nausea (16.8%). The most commonly used drugs were midazolam (76%) and demerol (43%). The average duration of the procedure was 18.3 minutes (range: 4-50). The most common findings were rectal polyps (18.7%) and hemorrhagic colitis (14.6%). In 77% of cases, the sedation was considered very good or good. Colon visualization was described as very good (51%) or good (36%). Seventy three percent of children had complete amnesia. The most common adverse effect was vomiting (7.5%). Conclusion: Lower endoscopies are feasible procedures to carry out in children, in an ambulatory basis, with intravenous sedation and minimum adverse effects.
