Surgical Treatment of Esophageal Advanced Achalasia

Of the several procedures that has to treat esophageal achalasia, the esophagectomy is to be the most indicated in advanced disease, which prompted Pinotti the disseminate the transmediastinal esophagectomy technique in the 1970s, with the advantage of avoiding thoracotomy. Nevertheless, several series demonstrated that this technique was not exempt from complications one of which could lead to massive hemopneumothorax due to injury to the trachea- bronchial tree and vessels due the periesophagitis that may be present with consequent adherence of the esophagus to these noble organs. Thus, Aquino in 1996 introduced the esophageal mucosectomy technique with preservation of the esophageal muscle tunic at the level of mediastinum as well as the transposition of the stomach to the cervical region inside in this tunic for the reconstruction of digestive tract. The advantage of this procedure is to avoid transgression of the mediastinum. This author describes in details this procedure, and shows early results and late evaluation using the ECKARDT score in a series of patients showing the advantages of the esophageal mucosectomy due the low incidence of immediate postoperative complications and good resolution in long term due the absence of symptoms in most patients

Salvage Esophagectomy in Advanced Esophageal Cancer

Even through the esophageal cancer has innumerable treatment options, its prognosis is still unsettled. Because esophagectomy is rarely curative, others therapies, such as chemoradiation emerging in advanced disease followed or not surgery. The salvage esophagectomy is an alternative for those patients with recurrent disease. Thus in this chapter the intend is show the results of the salvage esophagectomy in patients with esophageal cancer who had previously undergone chemoradiation and discussion about the morbidity of this surgical tecnic. Too, its show the our experience in 72 patients with unresectabeled esophageal carcinoma were treated with chemorradiation followed by salvage esophagectomy by trans-toracic approach. Patients was evaluated with regard pos-operative complications and disease free survival. The major complications was deiscence at the level of the of the anastomosis esophagogastric cervical, presents in 16 patients (22,2%) and pulmonar infection in 23 patients (31,9%). In 53 patients that were available for a five years follow-up, was a rate of 43,3% (23 patients) of disease free survival. Thus with the results its conclude that the salvage esophagectomy seems to be valuable in cases without any other therapeutic options

Evolution of nutritional status of infants infected with the human immunodeficiency virus

CONTEXT: There are today only a limited number of studies defining growth parameters and nutritional status for HIV children. OBJECTIVE: To study the nutritional status of infants infected with the human immunodeficiency virus. TYPE OF STUDY: Longitudinal study. SETTING: Department of Pediatrics, Faculty of Medical Sciences, UNICAMP, Campinas, Brazil. PARTICIPANTS: One hundred and twenty-four children born to HIV infected mothers were evaluated from birth until the age of two years. They were subdivided into two groups: 71 infected children and 53 non-infected children. MAIN MEASUREMENTS: Growth was evaluated in both groups by comparing Z-scores for weight/age (w/a), length/age (H/a) and weight/length (w/H) (using the NCHS curves as reference). RESULTS: The Z-score analyses showed that there was a significant difference between the two groups for all the variables studied, except for the H/a value at 3 months of age and the W/H value at 21 months of age, which showed P > 0.05. CONCLUSIONS: The growth of infected infants was observed to be severely affected in comparison with that of seroreversed infants in the same age groups. Although clinical manifestations may take time to appear, the onset of growth changes begin soon after birth.CONTEXTO: Atualmente há estudos limitados que definem parâmetros de crescimento e estado nutricional em crianças com HIV. OBJETIVO: Estudar o estado nutricional de crianças infectadas com o vírus da imunodeficiência humana. TIPO DE ESTUDO: Estudo longitudinal. LOCAL: Serviço de imunodeficiência pediátrica da Universidade Estadual de Campinas, Campinas, Brasil. PARTICIPANTES: 124 crianças nascidas de mulheres infectadas com o HIV foram avaliadas desde o nascimento até dois anos de idade. Elas foram subdivididas em dois grupos: 71 crianças infectadas e 53 crianças não-infectadas. PROCEDIMENTOS: A avaliação do estado nutricional foi realizada pela comparação do Z-score para peso/idade(P/I),altura/idade(A/I) e peso/altura(P/A),usando as curvas do NCHS como referência. Para a comparação do Z-score foram utilizados os testes T de Student e U de Mann-Whitney. Os testes foram conduzidos ao nível de significância=5%. RESULTADOS: A análise do Z-score revelou que houve evidência de diferença entre os dois grupos, para todas as variáveis estudadas, exceto o índice de A/I aos 3 meses e P/A aos 21 meses. CONCLUSÕES: O estado nutricional das crianças infectadas foi gravemente afetado em comparação com as crianças sororreversoras no mesmo grupo de idade. Embora as manifestações clínicas possam demorar a aparecer, as alterações no crescimento surgem logo após o nascimento.Pontifícia Universidade Católica de Campinas Department of NutritionUniversidade Metodista de PiracicabaState University of Campinas Faculty of Medical Sciences Department of PediatricsFederal University of São Paulo Department of PediatricsUNIFESP, Department of PediatricsSciEL

Investigation of nutritional risk factors using anthropometric indicators in hospitalized surgery patients

CONTEXT: The investigation of risk factors associated with nutritional status could contribute for better knowledge of the malnutrition. OBJECTIVE: To investigate the incidence of malnutrition and its possible association with many parameters that assess nutritional status and to identify the associated risk factors. METHODS: The nutritional status was assessed in 235 hospitalized patients. Malnutrition was defined as present when the patient presented at least two anthropometric criteria below the normal range and habitual energy intake below 75% of the energy requirement (HEI/ER<75%). Gender, age, type of disease, recent weight change and dental problems were investigated as possible associated risk factors. The chi-square and Mann-Whitney tests were used to compare the data and univariate and multiple logistic regressions were used to identify the factors associated with malnutrition. The odds ratio (OR) and confidence interval (CI) of 95% were calculated with the significance level set at 5% (P<0.05). RESULTS: One-fifth (20%) of the patients were malnourished on admission to the hospital and 27.5% reported recent weight loss. Malnutrition (P<0.0001) was greater in patients with malignant diseases. The only variables significantly associated with malnutrition according to univariate logistic regression were recent weight loss (P = 0.0058; OR = 2.909; IC95% = 1.362; 6.212) and malignant disease (P = 0.0001; OR = 3.847; IC95% = 1.948; 7.597). When multiple regression was used in the model which included type of disease, malignant disease was shown to increase the chance of malnutrition fourfold (P = 0.0002; OR = 3.855; IC95% = 1.914; 7.766). When disease was excluded, recent weight loss also increased malnutrition fourfold (P = 0.0012; OR = 3.716; IC95% = 1.677; 8.236). CONCLUSION: Patients with a history of recent weight loss and those with malignant diseases are more susceptible to malnutrition

RELATIONSHIP BETWEEN NUTRITIONAL STATUS AND THE CLINICAL OUTCOMES OF PATIENTS WITH AND WITHOUT NEOPLASMS ACCORDING TO MULTIPLE CORRESPONDENCE ANALYSIS

ABSTRACT BACKGROUND For many years, many studies have reported undesirable outcomes that may occur during the hospital stay of patients diagnosed with malnutrition or even at some nutritional risk. OBJECTIVE To investigate the relationship between nutritional status and clinical outcomes during hospital stay using the multiple correspondence analysis technique. METHODS This cross-sectional study included 600 patients with and without neoplasms. The following data were collected: subjective global assessment, nutritional indicators, nutritional risk screening, anthropometric data (body mass index (BMI), mid-upper arm circumference (MUAC), mid-upper arm muscle circumference (MUAMC), triceps skinfold thickness (TST), recent weight loss (RWL)), and habitual energy intake (HEI/ER <75%). The clinical outcomes of interest were complications, length of hospital stay (LOHS), and death. The data were analyzed by the chi-square or Fisher&#8217;s exact test at a significance level of 5%. Multiple correspondence analysis was used for the multivariate data analysis. RESULTS The multiple correspondence analysis map for the patients with neoplasms showed that the following characteristics were associated and represented by death, complications, and a greater likelihood of LOHS &#8805;7 days: underweight according to BMI; TST, MUAC, and MUAMC &#8804;15th percentile; malnutrition according to the subjective global assessment; at nutritional risk according to the nutritional risk screening; being male; age &#8805;60 years; and HEI/ER <75%. The multiple correspondence analysis map for the patients without neoplasms showed that the following characteristics were associated and represented by death: underweight according to BMI; TST &#8804;15th percentile; malnutrition according to the subjective global assessment; and at nutritional risk according to the nutritional risk screening. Complications and LOHS &#8805;7 days represented the categories male, no recent weight loss, HEI/ER <75%, MUAC and MUAMC &#8804;15th percentile, TST between the 15th and 85th percentiles, and age <60 years. CONCLUSION The results of this study confirm an association between unsatisfactory nutritional indicators and undesirable clinical outcomes

Avaliação do estado nutricional precedente ao uso de nutrição enteral

CONTEXTO: O adequado diagnóstico do estado nutricional é de vital importância para a prescrição da terapia nutricional enteral no ambiente hospitalar. OBJETIVO: Avaliar indicadores do estado nutricional em pacientes ingressantes na terapia nutricional enteral em uma unidade hospitalar. MÉTODOS: Estudo transversal com 100 pacientes adultos, sendo analisado o estado nutricional de ingresso à terapia nutricional enteral, por meio do índice de massa corporal obtido do peso e estatura estimados a partir de fórmulas de predição, e de indicadores laboratoriais do estado metabólico e nutricional. RESULTADOS: do total, 29% dos pacientes foram classificados como desnutridos pelo índice de massa corporal, enquanto 80% dos mesmos apresentaram albumina abaixo do valor de referência (<3,2 g/dL). Não houve diferença na distribuição das causas de base da internação entre os grupos classificados quanto ao estado nutricional pelo índice de massa corporal, prevalecendo as doenças cardiovasculares e pulmonares entre as principais causas. As concentrações abaixo dos valores de referência de albumina não foram diferentes entre os grupos classificados pelo índice de massa corporal e pelo diagnóstico de internação. CONCLUSÃO: O índice de massa corporal estimado foi indicador específico do estado nutricional, porém pouco sensível, enquanto a albumina mostrou-se mais sensível, o que reafirma a necessidade da combinação de vários indicadores para obtenção de um adequado diagnóstico nutricional.CONTEXT: A proper diagnosis of the nutritional status is of the utmost importance for prescribing enteral nutrition therapy in the hospital environment. OBJECTIVE: To assess nutritional status indicators of patients about to receive enteral nutrition therapy in a hospital unit. METHODS: This cross-sectional study examined the nutritional status of 100 adult patients before they were introduced to enteral nutrition therapy by calculating their body mass index . Their height and weight were estimated by prediction formulas and laboratory indicators of nutritional and metabolic statuses. RESULTS: Almost one-third (29%) of the patients were classified as malnourished according to their body mass index, while 80% of them had low albumin values (<3.2 g/dL). When patients were grouped according to body mass index, the distribution of the reasons for hospitalization did not differ between the groups. Cardiovascular and pulmonary diseases prevailed as the main reasons for hospitalization. When patients were grouped according to body mass index and diagnosis upon admission, the rates of low albumin concentration, i.e., concentration below the reference value, did not differ between the groups. CONCLUSION: The estimated body mass index was a specific indicator of nutritional status but lacked sensitivity. Meanwhile, albumin was more sensitive, demonstrating that it is necessary to use many indicators in combination to diagnose nutritional status properly
