ABSTRACT

ABSTRACT Background: Southern Brazil has one of the highest incidences of esophageal squamous cell carcinoma in the world. Transthoracic esophagectomy allows more complete abdominal and thoracic lymphadenectomy than transhiatal. However, this one is associated with less morbidity. Aim: To analyze the outcomes and prognostic factors of squamous esophageal cancer treated with transhiatal procedure. Methods: All patients selected for transhiatal approach were included as a potentially curative treatment and overall survival, operative time, lymph node analysis and use of neoadjuvant therapy were analyzed. Results: A total of 96 patients were evaluated. The overall 5-year survival was 41.2%. Multivariate analysis showed that operative time and presence of positive lymph nodes were both associated with a worse outcome, while neoadjuvant therapy was associated with better outcome. The negative lymph-node group had a 5-year survival rate of 50.2%. Conclusion: Transhiatal esophagectomy can be safely used in patients with malnutrition degree that allows the procedure, in those with associated respiratory disorders and in the elderly. It provides considerable long-term survival, especially in the absence of metastases to local lymph nodes. The wider use of neoadjuvant therapy has the potential to further increase long-term survival.


RESUMO Racional: O sul do Brasil tem uma das maiores incidências de carcinoma epidermoide do esôfago no mundo. A esofagectomia transtorácica permite linfadenectomia abdominal e torácica mais completa do que a transhiatal. No entanto, esta está associado à menor morbidade. Objetivo: Analisar os desfechos e fatores prognósticos do câncer epidermoide do esôfago que foram tratados com procedimento transhiatal. Métodos: Foram incluídos todos os pacientes selecionados para abordagem transhiatal como tratamento potencialmente curativo correlacionando sobrevida geral, tempo operatório, análise de linfonodos e uso de terapia neoadjuvante. Resultados: Foram avaliados 96 pacientes. A sobrevida geral em cinco anos foi de 41,2%. A análise multivariada mostrou que o tempo operatório e a presença de linfonodos positivos foram associados a pior resultado, enquanto a terapia neoadjuvante contribuiu para melhor resultado. O grupo de linfonodos negativos teve taxa de sobrevivência em cinco anos de 50,2%. Conclusão: A esofagectomia transhiatal pode ser empregada com segurança em pacientes que apresentem desnutrição com grau que permita o procedimento, nos com distúrbios respiratórios associados e nos idosos. Proporciona sobrevida em longo prazo considerável, especialmente na ausência de metástases para linfonodos locais. O uso mais amplo da terapia neoadjuvante tem o potencial de aumentar ainda mais a sobrevida em longo prazo.

ABSTRACT

Introduction: Malignant esophageal neoplasia is a rare tumor, but it has high morbidity and mortality. Early diagnosis and intensive treatment associated with surgical approach remains the best treatment for the disease. Its epidemiology is extremely diverse in the world, even in the same country. Methods: This was a retrospective analysis made from 2000-2015, analyzing the mortality rates of malignant esophageal neoplasia in the state of Rio Grande do Sul (RS) in its 30 Health Regions and in Brazil. The mortality data were collected in the Mortality Information System (SIM) and the population data in the Brazilian Institute of Geography and Statistics (IBGE). Results: The esophageal cancer mortality rate was 8.61 (95% CI, 8.49-8.73) per 100,000 inhabitants in RS, while the national rate was 3.66 (95% CI, 3, 49-3.82), with a significant difference (p <0.0001). The regional distribution was variable, and the West Border region presented the highest rate, 12.91 (95% CI, 12.05-13.77). However, even regions with lower mortality presented twice as much deaths than the national rate. Mortality increased with aging, with the oldest age groups (≥80 years) presenting 69.62 (95% CI, 64.9-74) deaths per 100,000 inhabitants. Conclusion: Esophageal neoplasia is still a very serious condition in the state of RS, being associated with an almost 3-fold higher mortality rate compared to the national rate. Even within the state different epidemiological patterns are found. (AU)

ABSTRACT

Objetivo: Estudar a relação entre perda de peso e a utilização de balão intragástrico. Método: Estudo transversal prospectivo desenvolvido com 50 usuários de balão intragástrico em um centro de referência em aparelho digestório no Rio Grande do Sul. Foi calculado o índice de massa corporal (IMC), dividindo-se o peso (quilograma) pela altura (metro) elevada ao quadrado e considerado normal IMC<25; como sobrepeso 25-29,9;IMC 30-34,9 como obesidade grau I; IMC 35-39,9 como obesidade grau II e IMC>40 obesidade grau III, conforme Organização Mundial da Saúde (OMS)/2000. Resultados: Foram avaliados 50 pacientes com estado nutricional entre sobrepeso e obesidade grau III, conforme classificação da OMS/2000. Em relação à porcentagem de perda de peso, observou-se que 46% dos pacientes tiveram uma perda entre 10-15 kg, 24% perda menor que 10 kg, 22% perda entre 15-20 kg e 8% perda maior de 20 kg. Conclusão: Embora a perda média fique entre 15 a 20% do peso inicial, esta perda seja extremamente variável e dependa de vários fatores, como peso inicial, adaptação, volume de preenchimento, disposição emocional para mudanças, adesão ao controle clínico e nutricional, grau de atividade física, metabolismo basal, a motivação e a disciplina para implantar as mudanças são os grandes determinantes deste resultado. Contudo, podemos observar, no presente estudo, evidências sobre a eficácia do tratamento com balão intragástrico em pacientes obesos.(AU)


Objective: To study the relationship between weight loss and use intragastric balloon. Methods: A prospective cross-sectional study was carried out with 50 intragastric balloon users at a reference center in a gastrointestinal tract in RS. The body mass index (BMI) was calculated by dividing the weight (kilogram) by the height (meter) elevated squared and considered normal BMI <25; As overweight 25-29.9; BMI 30-34.9 as obesity grade I; BMI 35-39,9 as obesity grade II and BMI> 40 obesity grade III according to World Health Organization (WHO)/ 2000. Results: Fifty patients with nutritional status between overweight and grade III obesity were evaluated, according to WHO / 2000 classification. Regarding the percentage of weight loss, it was observed that 46% of the patients had a loss between 10-15 kg, 24% a loss less than 10 kg, 22% loss between 15-20 kg and 8% loss greater than 20 kg. Conclusion: Although the average loss is between 15 and 20% of the initial weight, this loss be extremely variable and depends on several factors such as initial weight, adaptation, filling volume, emotional disposition for changes, adherence to clinical and nutritional control, degree of physical activity, basal metabolism, motivation and discipline to implant the changes are the major determinants of this result. However, we can observe in the present study evidence on the efficacy of intragastric balloon treatment in obese patients.(AU)

ABSTRACT

INTRODUÇÃO: O adenocarcinoma de esôfago apresenta aumento de frequência nas últimas décadas, particularmente em países desenvolvidos. O esôfago de Barrett é reconhecido como a principal lesão precursora e o estudo da sequência metaplasia-displasia-adenocarcinoma mostra a ocorrência de alterações genéticas desde suas fases mais incipientes. As alterações no p16INK4a são relatadas como frequentes no esôfago de Barrett e no carcinoma de esôfago. OBJETIVO: Verificar a prevalência da expressão imunoistoquímica da proteína p16INK4a em exames anatomopatológicos de pacientes com adenocarcinoma de esôfago. MÉTODO: A população do estudo foi constituída de 37 pacientes com adenocarcinoma de esôfago. A expressão da proteína p16 foi detectada por meio de análise imunoistoquímica, com anticorpo primário p16INK4aAb-7, clone 16P07, NeoMarkers e avaliada de acordo com o Sistema de Escore de Imunorreatividade (Immunoreactive scoring system - IRS) modificado. RESULTADOS: No grupo houve predominância de pacientes do sexo masculino (86,5 por cento) e a maioria dos casos correspondia a estádios avançados (III e IV = 67,5 por cento). Em 12 casos (32,4 por cento) foi identificada expressão imunoistoquímica da proteína p16INK4a. Não foi observada relação significativa entre a perda da expressão da proteína p16INK4a e o grau de diferenciação histológica (p=0,81) nem com o estadiamento da doença (p=0,485). CONCLUSÃO: Ocorre perda da expressão imunoistoquímica da proteína p16INK4a, corroborando as informações de que a inativação do gene p16 é um evento frequente e que pode exercer papel importante na carcinogênese do adenocarcinoma de esôfago.


BACKGROUND: The esophageal adenocarcinoma shows an increasing frequence in the last decades, specially in the developed countries. The Barrett´s esophagus is accepted as the major premalignant lesion and the metaplasia-dysplasia-adenocarcinoma sequence presents a lot of genetic changes since its early events. The alterations in p16INK4a are frequent in Barrett´s esophagus and esophageal carcinoma. AIM: To verify the prevalence of the immunohistochemical expression of the p16INK4a protein in patients with esophageal adenocarcinoma. METHODS: The study population consisted of 37 patients with resected esophageal adenocarcinoma. The p16INK4a protein expression was determined by immunohistochemistry using primary antibody p16INK4aAb-7, clone 16P07 NeoMarkers and assessed according to the Immunoreactive scoring system (IRS). RESULTS: Of 37 analyzed patients, the most were male (86,5 percent) and the advanced disease was predominant (stages III and IV = 67,5 percent). In 12 (32,4 percent) the immunohistochemistry was positive for p16INK4a.There was no significative relation between the protein expression and the degrees of histological differentiation of the biopsies and surgical especimens (p=0,81) neither with the staging (p=0,485). CONCLUSION: The lost of the immunohistochemical expression of the p16INK4a protein in this study suggests that p16 is enroled in the carcinogenesis of the adenocarcinoma of esophagus.

ABSTRACT

PURPOSE: To evaluate hyperbaric oxygen therapy (HBO) after esophagojejunal anastomosis in a rat experimental model and the effect of HBO on the healing of esophagojejunal anastomosis in gastrectomized rats. METHODS: Forty adult male Wistar rats, weighing 322 g to 506 g, were divided into two random groups. In group A (control group), 20 rats were subjected to total gastrectomy. In group B, 20 rats were similarly gastrectomized, but also received postoperative HBO treatment for 90 minutes/day for seven days. All rats were sacrificed on the eighth postoperative day and evaluated according to the following study variables: a) presence of anastomotic fistula; b) evaluation of esophagojejunal anastomosis healing by measuring the breaking strength at the suture line as per Hendriks & Mastboom; and c) determining the collagen concentration in the anastomosis, as per Kovács criteria. For the comparative statistical analysis between groups, Student's "t" test was used. A value of p<0.05 was considered significant. RESULTS: There was a 20 percent mortality rate. There were five deaths in group A and three in group B (p=N.S.). There was only one anastomotic fistula in each group, and neither caused any morbidity or death. Breaking strength measured at the suture line (p=0.528) and collagen concentration determined at the esophagojejunal anastomosis (p=0.89) were not significantly different between Groups A and B. CONCLUSION: Hyperbaric oxygen therapy did not affect the healing process of esophagojejunal anastomosis.


OBJETIVO: Avaliar o efeito da oxigenoterapia hiperbárica na cicatrização da anastomose esôfagojejunal em ratos gastrectomizados. MÉTODOS: 40 ratos Wistar, adultos machos, pesando entre 322g e 506g, foram divididos aleatoriamente em dois grupos. No grupo A (grupo controle) 20 ratos foram submetidos à gastrectomia total. No grupo B, 20 ratos foram gastrectomizados e receberam tratamento pós-operatório com oxigênio hiperbárico, 90 minutos/dia durante sete dias. Todos os ratos foram sacrificados no oitavo dia pós-operatório e avaliados de acordo com as seguintes variáveis: a) presença de fístula anastomótica; b) avaliação da cicatrização da anastomose esôfagojejunal pela medida da força de ruptura à tração na linha da sutura conforme Hendriks & Mastboom; c) determinação da concentração de colágeno na anastomose pelos critérios de Kovács. Para análise estatística comparativa entre os grupos foi utilizado o teste "t" de Student, considerando-se como significativo o valor de p=0.05. RESULTADOS: A mortalidade foi de 20 por cento. Morreram cinco ratos do grupo A e tres do grupo B (p= N.S.). Ocorreu uma fístula anastomótica em cada grupo não relacionadas a óbito. A medida da força de ruptura à tração na linha da sutura (p= 0.528) e a determinação da concentração de colágeno na anastomose esôfagojejunal (p= 0.89) não mostrou diferença estatisticamente significativa entre os grupos A e B. CONCLUSÃO: A oxigenoterapia hiperbárica não interferiu no processo de cicatrização da anastomose esôfagojejunal.

ABSTRACT

RACIONAL: O tratamento cirúrgico do divertículo de Zenker inclui na maioria dos casos a cricomiotomia do músculo cricofaríngeo, a qual pode ser associada à diverticulopexia ou diverticulectomia. A escolha destas opções cirúrgicas ainda é controversa. OBJETIVO: Avaliar os resultados de dois tratamentos cirúrgicos (diverticulopexia ou diverticulectomia, ambos associados à cricomiotomia) em uma série de casos. MÉTODOS: Estudo retrospectivo em período de 10 anos de 26 pacientes submetidos ao tratamento cirúrgico do divertículo de Zenker. Para análise estatística, os pacientes foram divididos em dois grupos: Grupo 1 - diverticulectomia (n=17) e Grupo 2 - diverticulopexia (n=9). Em todos realizou-se miotomia. Foram avaliadas as variáveis: tempo cirúrgico, de internação e de início da alimentação via oral, complicações gerais, ocorrência de fístulas, recidiva dos sintomas e mortalidade. Consideraram-se diferenças significativas quando P<0.05. RESULTADOS: A idade média dos pacientes foi de 64 anos. Sintomas pré-operatórios principais: disfagia (91 por cento) e regurgitação (46 por cento). Todos foram investigados com estudo radiográfico contrastado de faringe-esôfago-estômago e 58 por cento dos casos com endoscopia digestiva alta. Não houve diferença significativa entre os Grupos 1 e 2 em relação ao tempo operatório (96 x 99 min), tempo de internação (5,5 x 5 dias), início da alimentação via oral (7,5 x 4 dias), ocorrência de fístulas esôfago-cutâneas (35 x 22 por cento), recidiva da disfagia (6 x 11 por cento), complicações pós-operatórias em geral (41 x 33 por cento) e tempo de seguimento (7,5 x 9 meses). A mortalidade foi nula. CONCLUSÃO: O tratamento cirúrgico do divertículo de Zenker é método terapêutico relativamente seguro, com morbidade aceitável e seus resultados independem da opção por ressecção ou pexia do divertículo.


BACKGROUND: Surgical treatment of Zenker's Diverticulum comprise in the majority of cases cricopharyngeal miotomy, which may be associated with diverticulopexy or diverticulectomy. The election of these surgical options remains controversial. AIM: To evaluate the results of two surgical treatments (diverticulopexy or diverticulectomy, both associated with miotomy) in a case series. METHODS: Retrospective study comprising a 10-year period of 26 patients submitted to surgical treatment of Zenker's Diverticulum. For statistical analysis, patients were divided in two groups: Group 1 - diverticulectomy (n=17), and Group 2 - diverticulopexy (n=9). All were submitted also to a cricomiotomy. The following variables were evaluated: operative time, in-hospital stay, time to initiate oral feeding, general complications, fistula occurrence, symptom recurrence and mortality. Significant differences considered when P<0.05. RESULTS: Mean age was 64 years. Main pre-operative symptoms were: dysphagia (91 percent) and regurgitation (46 percent). All patients were diagnosed with pre-operative barium esophagram and 58 percent (n=15) did upper gastrointestinal endoscopy. There wasn't significant difference related to mean operative time (96 x 99 min), in-hospital stay (5,5 x 5 days), time to initiate oral feeding (7,5 x 4 days), occurrence of esophagocutaneous fistula (35 x 22 percent), dysphagia recurrence (6 x 11 percent), general post-operative complications (41 x 33 percent) and follow up period ( 7,5 x 9 months). The mortality was null. CONCLUSION: Surgical treatment of Zenker's Diverticulum is a relatively safe therapeutic method, with acceptable morbidity and the results are comparable between diverticulopexy and diverticulectomy.

ABSTRACT

The Barrett's esophagus (BE) is defined as endoscopically visible columnar mucosa at the distal esophagus, of any extension, proved to harbor intestinal metaplasia on biopsy, highlighted by the presence of goblet cells. BE denotes long-standing gastroesophageal reflux disease (GERD) and is an important risk factor for the development of esophageal adenocarcinoma (EAC). Therefore, these patients must be on follow-up, in order to diagnose cancer early. BE patients have frequent alterations in esophageal physiologyc studies. Alkaline duodenogastroesophageal reflux seems to have important role. The development BE occurs in steps, initially with formation of cardiac type mucosa subsequent intestinalization. Futher progression can follow a sequence, from low grade dysplasia, to high grade dysplasia and esophageal adenocarcinoma. Current follow-up is based on the presence of dysplasia. It has limitations, grouping patients heterogeneously. Different steps of carcinogenesis have been studied looking for an ideal prognostic marker. Uncontrolled proliferative activity, apoptosis inhibition, angiogenesis, tissue invasion and metastases formation are all implicated in cancer origin. Some cycle cell molecules have been studied in BE, such as retinoblastoma protein, ciclins, kinase dependent ciclins and cell cycle inhibitors. The P53 protein is one of the most investigated in the metaplasia-adenocarcinoma progression. Growth Factors, apoptotic proteins, telomers and DNA ploidy have also been searched. Increased proliferative activity has been implicated in Barrett's carcinogenesis and the Ki-67 antigen, through imunohistochemical analysis, has become the the method of choice. Present in the nucleus, it is found in proliferative cells only. Some studies suport association between Ki-67 activity and the metaplasia-dysplasia-adenocarcinoma sequence.The results, however, are inconclusive and research should follow this way.
