RESUMO
BACKGROUND: Despite the preference for multimodal treatment for gastric cancer, abandonment of chemotherapy treatment as well as the need for upfront surgery in obstructed patients brings negative impacts on the treatment. The difficulty of accessing treatment in specialized centers in the Brazilian Unified National Health System (SUS) scenario is an aggravating factor. AIMS: To identify advantages, prognostic factors, complications, and neoadjuvant and adjuvant therapies survival in gastric cancer treatment in SUS setting. METHODS: The retrospective study included 81 patients with gastric adenocarcinoma who underwent treatment according to INT0116 trial (adjuvant chemoradiotherapy), CLASSIC trial (adjuvant chemotherapy), FLOT4-AIO trial (perioperative chemotherapy), and surgery with curative intention (R0 resection and D2 lymphadenectomy) in a single cancer center between 2015 and 2020. Individuals with other histological types, gastric stump, esophageal cancer, other treatment protocols, and stage Ia or IV were excluded. RESULTS: Patients were grouped into FLOT4-AIO (26 patients), CLASSIC (25 patients), and INT0116 (30 patients). The average age was 61 years old. More than 60% of patients had pathological stage III. The treatment completion rate was 56%. The pathological complete response rate of the FLOT4-AIO group was 7.7%. Among the prognostic factors that impacted overall survival and disease-free survival were alcoholism, early postoperative complications, and anatomopathological status pN2 and pN3. The 3-year overall survival rate was 64.9%, with the CLASSIC subgroup having the best survival (79.8%). CONCLUSIONS: The treatment strategy for gastric cancer varies according to the need for initial surgery. The CLASSIC subgroup had better overall survival and disease-free survival. The INT0116 regimen also protected against mortality, but not with statistical significance. Although FLOT4-AIO is the preferred treatment, the difficulty in carrying out neoadjuvant treatment in SUS scenario had a negative impact on the results due to the criticality of food intake and worse treatment tolerance.

BACKGROUND: Curative treatment for gastric cancer involves tumor resection, followed by transit reconstruction, with Roux-en-Y being the main technique employed. To permit food transit to the duodenum, which is absent in Roux-en-Y, double transit reconstruction has been used, whose theoretical advantages seem to surpass the previous technique. AIMS: To compare the clinical evolution of gastric cancer patients who underwent total gastrectomy with Roux-en-Y and double tract reconstruction. METHODS: A systematic review was carried out on Web of Science, Scopus, EmbasE, SciELO, Virtual Health Library, PubMed, Cochrane, and Google Scholar databases. Data were collected until June 11, 2022. Observational studies or clinical trials evaluating patients submitted to double tract (DT) and Roux-en-Y (RY) reconstructions were included. There was no temporal or language restriction. Review articles, case reports, case series, and incomplete texts were excluded. The risk of bias was calculated using the Cochrane tool designed for randomized clinical trials. RESULTS: Four studies of good methodological quality were included, encompassing 209 participants. In the RY group, there was a greater reduction in food intake. In the DT group, the decrease in body mass index was less pronounced compared to preoperative values. CONCLUSIONS: The double tract reconstruction had better outcomes concerning body mass index and the time until starting a light diet; however, it did not present any advantages in relation to nutritional deficits, quality of life, and post-surgical complications.

RESUMO RACIONAL: O tratamento curativo do câncer gástrico envolve a ressecção do tumor, seguida de reconstrução do trânsito, sendo o Y-de-Roux a principal técnica empregada. Para permitir o trânsito alimentar para o duodeno, ausente em Y-de-Roux, tem-se utilizado a reconstrução de duplo trânsito, cujas vantagens teóricas parecem superar a técnica anterior. OBJETIVOS: Comparar a evolução clínica de pacientes com câncer gástrico submetidos à gastrectomia total com Y-de-Roux e reconstrução de duplo trânsito. MÉTODOS: Foi realizada uma revisão sistemática nas bases de dados: Web of Science, Scopus, Embase, Scielo, Biblioteca Virtual em Saúde, PubMed e Cochrane. Os dados foram coletados até 11 de junho de 2022. Foram incluídos estudos observacionais ou ensaios clínicos avaliando pacientes que utilizaram reconstruções de duplo trânsito (DT) e Y-de-Roux (RY). Não houve restrição temporal ou de idioma. Foram excluídos artigos de revisão, relatos de casos, séries de casos e aqueles com texto incompleto. O risco de viés foi calculado utilizando a ferramenta Cochrane desenvolvida para ensaios clínicos randomizados. RESULTADOS: Foram incluídos quatro estudos de boa qualidade metodológica, abrangendo 209 participantes. No grupo RY houve maior redução na ingestão alimentar. No grupo DT, a diminuição do índice de massa corporal (IMC) foi menos pronunciada em comparação aos valores pré-operatórios. CONCLUSÕES: A reconstrução de duplo trânsito apresentou melhores resultados em relação ao índice de massa corporal e ao tempo para início de dieta leve, porém não apresentou vantagens em relação aos déficits nutricionais, qualidade de vida e complicações pós-cirúrgicas.

RESUMO RACIONAL: Apesar da preferência pelo tratamento multimodal para o câncer gástrico, o abandono do tratamento quimioterápico bem como a necessidade de cirurgia "upfront" em pacientes obstruídos traz impactos negativos para o tratamento. A dificuldade de acesso ao tratamento em centros especializados no Sistema Único de Saúde (SUS) é um agravante. OBJETIVOS: Identificar vantagens, fatores prognósticos, complicações e sobrevida de terapias neoadjuvantes e adjuvantes no tratamento do câncer gástrico no cenário do SUS. MÉTODOS: Estudo retrospectivo incluindo 81 pacientes com adenocarcinoma gástrico submetidos a tratamento segundo os protocolos INT0116 (quimiorradioterapia adjuvante), CLASSIC (quimioterapia adjuvante), FLOT4-AIO (quimioterapia perioperatória) e cirurgia com intuito curativo (ressecção R0 e linfadenectomia D2) em um único centro oncológico entre 2015 e 2020. Indivíduos com outros tipos histológicos, coto gástrico, câncer de esôfago, outros protocolos de tratamento e estádio Ia ou IV foram excluídos. RESULTADOS: Os pacientes foram distribuídos em: FLOT4-AIO (26 pacientes), CLASSIC (25 pacientes) e INT0116 (30 pacientes). A média de idade foi 61 anos. Mais de 60% dos pacientes apresentaram estádio III patológico. A taxa de completude do tratamento foi 56%. A taxa de resposta patológica completa do grupo FLOT4-AIO foi 7,7%. Dentre os fatores prognósticos que impactaram a sobrevida global e sobrevida livre de doença tivemos etilismo, complicações pós-operatórias precoces, status anatomopatológico pN2 e pN3. A taxa de sobrevida global em 3 anos foi 64,9% sendo o subgrupo CLASSIC com melhor sobrevida (79,8%). CONCLUSÕES: A estratégia de tratamento do câncer gástrico varia de acordo com a necessidade de cirurgia inicial. O subgrupo CLASSIC apresentou melhor sobrevida global e sobrevida livre de doença. O esquema INT0116 também protegeu contra a mortalidade, mas não com significância estatística. Apesar do FLOT4-AIO ser o tratamento de escolha, a dificuldade na realização da neoadjuvância no âmbito do SUS impactou negativamente nos resultados devido à criticidade da ingesta alimentar e à pior tolerância ao tratamento.
RESUMO
BACKGROUND: Gastric neuroendocrine tumors are a heterogeneous group of neoplasms that produce bioactive substances. Their treatment varies according to staging and classification, using endoscopic techniques, open surgery, chemotherapy, radiotherapy, and drugs analogous to somatostatin. AIMS: To identify and review cases of gastric neuroendocrine neoplasia submitted to surgical treatment. METHODS: Review of surgically treated patients from 1983 to 2018. RESULTS: Fifteen patients were included, predominantly female (73.33%), with a mean age of 55.93 years. The most common symptom was epigastric pain (93.3%), and the mean time of symptom onset was 10.07 months. The preoperative upper digestive endoscopy (UDE) indicated a predominance of cases with 0 to 1 lesion (60%), sizing ≥1.5 cm (40%), located in the gastric antrum (53.33%), with ulceration (60%), and Borrmann III (33.33%) classification. The assessment of the surgical specimen indicated a predominance of invasive neuroendocrine tumors (60%), with angiolymphatic invasion in most cases (80%). Immunohistochemistry for chromogranin A was positive in 60% of cases and for synaptophysin in 66.7%, with a predominant Ki-67 index between 0 and 2%. Metastasis was observed in 20% of patients. The surgical procedure most performed was subtotal gastrectomy with Roux-en-Y reconstruction (53.3%). Tumor recurrence occurred in 20% of cases and a new treatment was required in 26.67%. CONCLUSIONS: Gastric neuroendocrine tumors have a low incidence in the general population, and surgical treatment is indicated for advanced lesions. The study of its management gains importance in view of the specificities of each case and the need for adequate conduct to prevent recurrences and complications.

INTRODUCTION: in Brazil, trauma is responsible for 40% of deaths in the age group between 5 and 9 years old, and 18% between 1 and 4 years, and bleeding is the leading cause of preventable death in the traumatized child. Conservative management of blunt abdominal trauma with solid organs injury - started in the 60s - is the current world trend, with studies showing survival rates above 90%. The objective was to assess the efficacy and safety of conservative treatment in children with blunt abdominal trauma treated at the Clinical Hospital of the University of Campinas, in the last five years. METHODS: retrospective analysis of medical records of patients classified by levels of injury severity, in 27 children. RESULTS: only one child underwent surgery for initial failure of conservative treatment (persistent hemodynamic instability), resulting in a 96% overall success rate of the conservative treatment. Five other children (22%) developed late complications that required elective surgery: a bladder injury, two cases of infected perirenal collections (secondary to injury of renal collecting system), a pancreatic pseudocyst and a splenic cyst. Resolution of the complications was attained in all children, with anatomical and functional preservation of the affected organ. There were no deaths in this series. CONCLUSION: the conservative initial approach in the treatment of blunt abdominal trauma was effective and safe with high resolution and low rate of complications leading to a high preservation rate of the affected organs. Level of evidence III - prognostic and therapeutic study.

BACKGROUND: Caustic ingestion is still a health problem of utmost importance in the West. In developing countries, this incident remains at increase and it is associated with unfavorable factors like social, economic, and educational handicaps, besides a lack of prevention. Esophagocele is a rare consequence of caustic ingestion. AIM: We aimed to describe a patient with multiple caustic ingestions who presented an esophagocele resected by videothoracoscopy. METHODS: A woman ingested caustic soda when she was only 17 years old in a suicidal attempt during a depressive crisis. Initially, she was submitted to a retrosternal esophagocoloplasty with the maintenance of her damaged esophagus. After 1 year of this first surgery, she ingested caustic soda again in a new suicidal attempt. Her transposed large bowel in the first surgery became narrow, being replaced in a second surgery by a retrosternal esophagogastroplasty. Still, at the second surgery, her damaged esophagus remained in its original position in the posterior mediastinum. However, after 5 years, she developed an esophagocele. RESULTS: The esophagocele was resected through videothoracoscopy in a prone position, employing four trocars. The postoperative was uneventful. CONCLUSION: Esophageal exclusion must always be recorded because esophagocele presents unspecific symptoms. The videothoracoscopy in a prone position is an excellent technical option to resect esophagoceles.

BACKGROUND/OBJECTIVES: The association between systemic inflammation and myosteatosis upon diagnosis of gastric cancer (GC) and whether these factors could predict survival outcomes is not clear. Our aim was to explore the association between systemic inflammation and myosteatosis upon diagnosis of GC, specially whether the co-occurrence of these factors could predict survival outcomes. SUBJECTS/METHODS: Computed tomography (CT) was performed at the level of the third lumbar vertebra for body composition analysis in 280 patients with GC. Myoesteatosis was defined as the lowest tertile of the muscle radiodensity distribution or based on clinical significance using optimal stratification analysis. Inflammatory indexes were measured, including the neutrophil-to-lymphocyte (NLR), platelet-to-lymphocyte and lymphocyte-to-monocyte ratios. RESULTS: Patients with low skeletal muscle (SM) radiodensity were more likely to be older than 65 years, have a higher body mass index and have diabetes. They also had higher intermuscular visceral and subcutaneous adipose tissue areas and indexes. The highest tertile of SM radiodensity was associated with better disease-free survival (DFS) (HR = 0.51, 95% CI [0.31, 0.84], ptrend = 0.020) and overall survival (OS) (HR = 0.49, 95% CI [0.29, 0.82], ptrend = 0.022). Patients with NLR > 2.3 and myosteatosis had the worst DFS and OS (HR = 2.77, 95% CI [1.54, 5.00], p = 0.001; HR = 3.31, 95% CI [1.79, 6.15], p < 0.001, respectively). CONCLUSION: Co-occurrence of myosteatosis and inflammation increased disease progression and death risk by almost three times. These regularly obtained biomarkers might improve prognostic risk prediction in resectable GC.

RESUMO Introdução: no Brasil, o trauma é responsável por 40% dos óbitos na faixa etária entre 5 e 9 anos, e 18% entre 1 e 4 anos, e o sangramento é a principal causa de prevenção morte na criança traumatizada. O manejo conservador de trauma abdominal contuso com lesão de órgãos sólidos - iniciado na década de 60 - é a tendência mundial atual, com estudos mostrando taxas de sobrevivência acima de 90%. O objetivo do presente trabalho foi avaliar a eficácia e segurança do tratamento conservador em crianças com trauma abdominal contuso tratado no Hospital das Clínicas da Universidade de Campinas, nos últimos cinco anos. Métodos: análise retrospectiva de prontuários de pacientes classificados por níveis de gravidade da lesão, em 27 crianças. Resultados: apenas uma criança foi submetida a cirurgia por falha inicial do tratamento conservador (instabilidade hemodinâmica persistente), resultando em uma taxa de sucesso global de 96% do tratamento conservador inicial. Outras cinco crianças (22%) desenvolveram complicações tardias que exigiram cirurgias eletivas: lesão na bexiga, dois casos de coleção perirenal infectada (secundária à lesão de sistema de coleta renal), um pseudocisto pancreático e um cisto esplênico. Resolução da complicação foi atingida em todas as crianças, com preservação anatômica e funcional do órgão afetado. Não houve mortes nesta série. Conclusão: a abordagem inicial conservadora no tratamento de trauma abdominal contundente foi eficaz e segura com alta resolução e baixa taxa de complicações levando a uma alta taxa de preservação dos órgãos afetados. Nível de evidência III - estudo prognóstico e terapêutico.

RESUMO RACIONAL: Os tumores neuroendócrinos gástricos são um grupo heterogêneo de neoplasias produtoras de substâncias bioativas, sendo o seu tratamento variável de acordo com o estadiamento e a classificação, sendo utilizadas técnicas endoscópicas, cirurgias abertas, quimioterapia, radioterapia e fármacos análogos da somatostatina. OBJETIVOS: Identificar e revisar os casos de neoplasia neuroendócrina gástrica submetidos a tratamento cirúrgico. MÉTODOS: Revisão os doentes tratados cirurgicamente de 1983 e 2018. RESULTADOS: Foram incluídos 15 pacientes, com predomínio do sexo feminino (73,33%) e média de idade de 55,93 anos. O sintoma mais comum foi a epigastralgia (93,3%) e o tempo médio do início dos sintomas foi de 10,07 meses. A endoscopia digestiva pré-operatória indicou predomínio de casos com 0 a 1 lesões (60%), de tamanho ≥ 1,5 cm (40%), localizadas em antro gástrico (53,33%), com ulceração (60%), Borrmann 3 (33,33%). A avaliação da peça cirúrgica indicou um predomínio de tumores neuroendócrinos invasivos (60%), com invasão angiolinfática na maioria dos casos (80%). A imuno-histoquímica para cromogranina A foi positiva em 60% dos casos e para sinaptofisina em 66,7%, com índice de Ki-67 predominante entre 0 e 2%. Metástases foram observadas em 20% dos casos. O procedimento cirúrgico mais utilizado foi a gastrectomia subtotal com reconstrução em Y de Roux (53,3%). Recidiva tumoral ocorreu em 20% dos casos e novo tratamento foi necessário em 26,67% dos casos. CONCLUSÕES: Os tumores neuroendócrinos gástricos apresentam baixa incidência na população em geral, e o tratamento cirúrgico está indicado nas lesões avançadas. O estudo de seu manejo ganha importância frente às especificidades de cada caso e a necessidade de conduta adequada para a prevenção de recidivas e complicações.
RESUMO
BACKGROUND: Endoscopic treatment of precancerous lesions and early gastric cancer has been widely accepted in recent years. Endoscopic submucosal dissection (ESD), following established indication criteria, can lead to cure of the disease in more than 90% of cases. OBJECTIVE: This study aimed to analyze the use of ESD in patients with early gastric cancer and precancerous lesions, as well as the results of the procedure, its complications and effectiveness in controlling the disease. METHODS: This is a retrospective cohort study composed of 41 patients aged from 53 to 87 years (mean age: 65 years; 58.53% male) who were analyzed from 2008 to 2019. The variables collected from the medical records were: comorbidities, classification of the lesion regarding resection criteria, type of resection, histology, degree of invasion, resection margin, complications, disease recurrence. Statistical analysis was performed using the Kruskal-Wallis test, the McNemar's test, and the Mann-Whitney test, with 5% statistical significance (P<0.05). RESULTS: The most frequent site of the lesion was the gastric antrum and the predominant presentation by the Japanese or Paris classification was the one with depressed components in 56.09%. Adenocarcinoma occurred in 75.6% of the biopsies, and the remainder were adenomas without neoplasia. En-bloc resection occurred in 97.57% of cases, and compromise of the safety margin occurred in one patient. The main pre-existing comorbidity was liver cirrhosis in 29.26% of cases. There was a significant increase in post- ESD adenocarcinoma compared to pre-resection diagnosis. The mean follow-up time was 38.4 months, with one recurrence (2.43%) and two metachronous lesions (4.87%). Complications during and after the procedure occurred in three patients (7.31%), being due to bleeding (two cases) and perforation (one case). There was one death due to a cardiac event not directly related to the procedure. CONCLUSION: Endoscopic submucosal dissection proved to be a safe procedure, with a low complication and recurrence rate. Its recommendation must occur within the established criteria; however, it can be indicated for patients outside the criteria, if there is a high risk for surgical treatment.

RESUMO Contexto: O tratamento endoscópico das lesões pré-cancerosas e do câncer gástrico precoce tem sido amplamente aceito nos últimos anos. A dissecção endoscópica da submucosa (submucosectomia), obedecendo a critérios estabelecidos de indicação, pode levar a cura da doença em mais de 90% dos casos. Objetivo: Este estudo teve como objetivo analisar o uso da dissecção submucosa endoscópica em pacientes com câncer gástrico precoce e lesões pré-cancerosas, bem como os resultados do procedimento, suas complicações e eficácia no controle da doença. Métodos: Foram analisados 41 pacientes, com idade variando de 53 a 87 anos (média de 65 anos), sendo 58,53% do sexo masculino, no período de 2008 a 2019, sendo este estudo do tipo coorte retrospectivo. As variáveis coletadas dos prontuários foram: comorbidades, classificação da lesão quanto aos critérios de ressecção, tipo de ressecção, histologia, grau de invasão, margem de resseção, complicações, recidiva de doença. A análise estatística foi feita com o uso do teste de Kruskal-Wallis, teste de McNemar e teste de Mann-Whitney, com significância estatística de 5% (P<0,05). Resultados: O local mais frequente da lesão foi o antro gástrico e a apresentação predominante pela classificação japonesa ou de Paris foram os com componentes deprimidos em 56,09%. O adenocarcinoma ocorreu em 75,6% das biópsias e o restante foram adenomas sem neoplasia. A ressecção em bloco ocorreu em 97,57% dos casos, e o comprometimento da margem de segurança ocorreu em um paciente. A principal comorbidade pré-existente foi a cirrose hepática em 29,26% dos casos. Houve um aumento significativo de adenocarcinoma após dissecção endoscópica da submucosa em comparação ao diagnóstico pré ressecção. O tempo médio de seguimento foi de 38,4 meses, sendo registrado uma recidiva (2,43%) e duas lesões metacrônicas (4,87%). As complicações durante e após o procedimento ocorreram em 3 (7,31%) pacientes, sendo por sangramento (dois casos) e perfuração (um caso). Houve um óbito por evento cardiológico, não relacionado diretamente com o procedimento. Conclusão: A ressecção endoscópica da submucosa mostrou ser procedimento seguro, com baixa taxa de complicação e de recidiva. A sua indicação deve ser dentro dos critérios estabelecidos, entretanto, pode ser indicada em pacientes fora de critérios, se há alto risco para o tratamento cirúrgico.
RESUMO
AIM: Esophagogastroduodenoscopies and colonoscopies are the main diagnostic examinations for esophageal, stomach, and colorectal tumors. This study aimed to evaluate the estimates of the incidence of esophageal, stomach, and colorectal cancer; population growth; and esophagogastroduodenoscopies and colonoscopies performed by the Unified Health System (SUS), from 2010 to 2018, in the five regions of the country, and to analyze the relationship between these values. RESULTS: The colorectal tumor had a significant elevation, while the esophageal and gastric maintained the incidences. In the five regions, there was a significant increase in the number of colonoscopies; however, this increase did not follow the increase in the population in the North and Northeast regions. There was no significant increase in the number of esophagogastroduodenoscopies in the North, Northeast, Midwest, and South regions, and in the North region there was a decrease. In the Northeast region, there was a decreasing number, and in the South and Midwest regions, the number of examinations remained stable in the period. The Southeast region recorded an increase in the number of examinations following the population growth. CONCLUSION: The current number of esophagogastroduodenoscopies and colonoscopies performed by the SUS did not follow the population growth, in order to attend the population and diagnose esophageal, stomach, and colorectal tumors. Therefore, the country needs to have adequate and strategic planning on how it will meet the demand for these tests and serve the population well, incorporating new technologies.

BACKGROUND: Multimodal therapy with neoadjuvant chemoradiotherapy, followed by esophagectomy has offered better survival results, compared to isolated esophagectomy, in advanced esophageal cancer. In addition, patients who have a complete pathological response to neoadjuvant treatment presented greater overall survival and longer disease-free survival compared to those with incomplete response. AIM: To compare the results of overall survival and disease-free survival among patients with complete and incomplete response, submitted to neoadjuvant chemoradiotherapy, with two therapeutic regimens, followed by transhiatal esophagectomy. METHODS: Retrospective study, approved by the Research Ethics Committee, analyzing the medical records of 56 patients with squamous cell carcinoma of the esophagus, divided into two groups, submitted to radiotherapy (5040 cGY) and chemotherapy (5-Fluorouracil + Cisplatin versus Paclitaxel + Carboplatin) neoadjuvants and subsequently to surgical treatment, in the period from 2005 to 2012, patients. RESULTS: The groups did not differ significantly in terms of gender, race, age, postoperative complications, disease-free survival and overall survival. The 5-year survival rate of patients with incomplete and complete response was 18.92% and 42.10%, respectively (p> 0.05). However, patients who received Paclitaxel + Carboplatin, had better complete pathological responses to neoadjuvant, compared to 5-Fluorouracil + Cisplatin (47.37% versus 21.62% - p = 0.0473, p <0.05). CONCLUSIONS: There was no statistical difference in overall survival and disease-free survival for patients who had a complete pathological response to neoadjuvant. Patients submitted to the therapeutic regimen with Paclitaxel and Carboplastin, showed a significant difference with better complete pathological response and disease progression. New parameters are indicated to clarify the real value in survival, from the complete pathological response to neoadjuvant, in esophageal cancer.

RESUMO - RACIONAL: Os tumores de esôfago, estômago e colorretal têm como principal exame diagnóstico as esofagogastroduodenoscopias e colonoscopias. OBJETIVO: Avaliar as estimativas de incidências de câncer de esôfago, estômago e colorretal, o crescimento populacional, e as esofagogastroduodenoscopias e colonoscopias realizadas pelo Sistema Único de Saúde (SUS) de 2010 a 2018, nas cinco regiões do país e a relação entre esses valores. RESULTADOS: O tumor colorretal teve elevação significativa, enquanto os esofágicos e gástricos mantiveram as incidências. Nas cinco regiões foi registrado elevação significativa do número de colonoscopias, entretanto, essa elevação não acompanhou a elevação da população nas regiões Norte e Nordeste. Não ocorreu elevação significativa do número de esofagogastroduodenoscopias nas regiões Norte, Nordeste, Centro-Oeste e Sul e na região Norte ocorreu diminuição. Na região Nordeste ocorreu número decrescente e nas regiões Sul e Centro-Oeste o número de exames manteve-se estável no período. A região Sudeste registrou elevação do número de exames acompanhando o crescimento população. CONCLUSÃO: O número atual de esofagogastroduodenoscopias e colonoscopias realizadas pelo SUS, não acompanhou o crescimento populacional, para atender a população e diagnosticar os tumores de esôfago, estômago e colorretais. Portanto, o país necessita ter um planejamento adequado e estratégico de como irá suprir a demanda desses exames e bem atender a população, incorporando as novas tecnologias.
RESUMO
ABSTRACT BACKGROUND: Caustic ingestion is still a health problem of utmost importance in the West. In developing countries, this incident remains at increase and it is associated with unfavorable factors like social, economic, and educational handicaps, besides a lack of prevention. Esophagocele is a rare consequence of caustic ingestion. AIM: We aimed to describe a patient with multiple caustic ingestions who presented an esophagocele resected by videothoracoscopy. METHODS: A woman ingested caustic soda when she was only 17 years old in a suicidal attempt during a depressive crisis. Initially, she was submitted to a retrosternal esophagocoloplasty with the maintenance of her damaged esophagus. After 1 year of this first surgery, she ingested caustic soda again in a new suicidal attempt. Her transposed large bowel in the first surgery became narrow, being replaced in a second surgery by a retrosternal esophagogastroplasty. Still, at the second surgery, her damaged esophagus remained in its original position in the posterior mediastinum. However, after 5 years, she developed an esophagocele. RESULTS: The esophagocele was resected through videothoracoscopy in a prone position, employing four trocars. The postoperative was uneventful. CONCLUSION: Esophageal exclusion must always be recorded because esophagocele presents unspecific symptoms. The videothoracoscopy in a prone position is an excellent technical option to resect esophagoceles.
RESUMO RACIONAL: A ingestão de produtos cáusticos ainda é um problema de saúde de extrema importância no Ocidente. Nos países em desenvolvimento, este incidente continua em ascensão e está associada a fatores desfavoráveis como sociais, econômicos e educacionais, além da falta de prevenção. A esofagocele é uma consequência rara da ingestão de cáusticos. OBJETIVO: Nosso objetivo é descrever um paciente com múltiplas ingestões cáusticas que apresentou uma esofagocele ressecada por videotoracoscopia. MÉTODOS: Doente feminina que ingeriu soda cáustica com 17 anos de idade, como tentativa de suicídio, durante uma crise depressiva. Inicialmente, foi submetida a esofagocoloplastia retroesternal com manutenção do esôfago lesado. Após um ano desta primeira cirurgia, voltou a ingerir soda cáustica, em nova tentativa de suicídio. Seu intestino grosso transposto na primeira cirurgia tornou-se estenosado, sendo substituído em uma segunda cirurgia, por esofagogastroplastia retroesternal. Ainda assim, nesta segunda cirurgia, o esôfago lesado permaneceu em sua posição original no mediastino posterior. No entanto, após cinco anos, ela desenvolveu uma esofagocele. RESULTADOS: A esofagocele foi ressecada por videotoracoscopia, em decúbito ventral, empregando-se quatro trocartes. O pós-operatório transcorreu sem intercorrências. CONCLUSÕES: A exclusão esofágica deve ser sempre registrada, pois a esofagocele apresenta sintomas inespecíficos. A videotoracoscopia em posição prona é uma excelente opção técnica para ressecção de esofagoceles.
RESUMO
OBJECTIVE: this study analyzed the surgical resident's study profile by assessing the use of electronic media. 44.76% of the physicians agreed on participating. METHODS: observational, cross-sectional non-controlled study. Statistical analysis was performed using Pearson's correlation coefficient and the significance level for the statistical tests was p <0.001. RESULTS: 87.2% of the residents believed that it is interesting to use e-learning together with the classical theoretic classes. 45% of the interviewed claimed to spend more than 3 hours on the Internet daily. CONCLUSION: residents recognize the importance of technology for education, but not as a way of replacing the traditional teaching methods.

RESUMO Racional: A terapia multimodal com quimioradioterapia neoadjuvantes, seguido de esofagectomia tem oferecido melhores resultados de sobrevida, em comparação à esofagectomia isolada, no câncer do esôfago avançado. Além disso, os doentes que apresentam resposta patológica completa ao tratamento neoadjuvante, têm evoluido com maior sobrevida global e maior sobrevida livre de doença em comparação aos que apresentam resposta incompleta. Objetivo: Comparar os resultados de sobrevida global e sobrevida livre de doença entre os doentes com resposta completa e incompleta, submetidos à quimioradioterapia neoadjuvante, com dois esquemas terapêuticos, seguidos de esofagectomia transhiatal. Métodos: Estudo retrospectivo, aprovado pelo Comitê de Ética em pesquisa, analisando os prontuários de 56 doentes, divididos em dois grupos de pacientes, submetidos a radioterapia (4400 a 5400 cGY) e quimioterapia (5-Fluorouracil+Cisplatina versus Paclitaxel+Carboplatina) neoadjuvantes e posteriormente a tratamento cirúrgico, no período de 2005 a 2012, portadores de carcinoma espinocelular do esôfago. Resultados: Os grupos não diferiram significativamente quanto ao gênero, raça, idade, complicações pós-operatórias, sobrevida livre de doença e sobrevida global. A sobrevida em 5 anos de doentes com resposta incompleta e completa foram, respectivamente, 18,92% e 42,10% (p>0,05). Entretanto, os doentes que receberam Paclitaxel+Carboplatina, tiveram melhores respostas patológicas completas à neoadjuvância, em comparação ao 5-Fluorouracil+Cisplatina (47,37% versus 21,62% - p=0,0473, p<0,05). Conclusões: Não houve diferença estatística na sobrevida global e na sobrevida livre de doença dos doentes que apresentaram resposta patológica completa à neoadjuvância. Os doentes submetidos ao esquema terapêutico com Paclitaxel e Carboplastina, mostraram diferença significativa com melhor resposta patológica completa e evolução da doença. Novos parâmetros são indicados para esclarecer o real valor na sobrevida, da resposta patológica completa à neoadjuvância, no câncer de esôfago.
